  • SQL Server, fetching data from multiple joined tables. Why is slow?

    - by user562192
    I have problem with performance when retrieving data from SQL Server. My sql query looks something like this: SELECT table_1.id, table_1.value, table_2.id, table_2.value,..., table_20.id, table_20.value From table_1 INNER JOIN table_2 ON table_1.id = table_2.table_1_id INNER JOIN table_3 ON table_2.id = table_3.table_2_id... WHERE table_1.row_number BETWEEN 1 AND 20 So, I am fetching 20 results. This query takes about 5 seconds to execute. When I select only table_1.id, it returns results instantly. Because of that, I guess that problem is not in JOINs, it is in retrieving data from multiple tables. Any suggestions how I would speed up this query?

  • SQL JOIN with two or more tables as output - most efficient way?

    - by littlegreen
    I have an SQL query that executes a LEFT JOIN on another table, then outputs all results that could be coupled into a designated table. I then have a second SQL query that executes the LEFT JOIN again, then outputs the results that could not be coupled to a designated table. In code, this is something like: INSERT INTO coupledrecords SELECT b.col1, b.col2... s.col1, s.col2... FROM bigtable AS b LEFT JOIN smallertable AS s ON criterium WHERE s.col1 IS NOT NULL INSERT INTO notcoupledrecords SELECT b.col1, b.col2... bigtable AS b LEFT JOIN smallertable AS s ON criterium WHERE s.col1 IS NULL My question: I now have to execute the JOIN two times, in order to achieve what I want. I have a feeling that this is twice as slow as it could be. Is this true, and if yes, is there a way to do it more efficiently?

  • SQL Server 2005: When clicking "Add" database I keep getting 'verify that the path or file exists'

    - by Code Sherpa
    When I right click on "databases" in Sql Server 2005 Management Studio and then Attach... Add I get the following error: C:\Documents and Settings\Administrator\My Documents\SQL Server Management Studio\ Projects\Path\To\MDF\And\LDF\Files\ cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists. The answer is easy - the MDF and LDF files where removed when Nant (by way of my dev machine) issued a drop command. But, after replacing the MDF and LDF files, I want to reattach the database but the above error keeps coming up when I select "Add". Also, I have already "unattached" the database in question and it no longer appears on the left under "databases". I have tried to replace a copy of the MDF and LDF files in the folder being referenced and that didn't work. Any ideas as to how to gracefully get rid of this error?

  • Use SQL to clone data in two tables that have a 1-1 relationship in each table

    - by AmoebaMan17
    Using MS SQL 2005, Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H I want to clone the data for GroupID == 1 into a new GroupID so that I result with the following: Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 5 | a | 23 | 3 6 | b | 24 | 3 7 | c | 25 | 3 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H 23 | H 24 | J 25 | K I've found some SQL clone patterns that allow me to clone data in the same table well... but as I start to deal with cloning data in two tables at the same time and then linking up the new rows correctly... that's just not something I feel like I have a good grasp of. I thought I could do some self-joins to deal with this, but I am worried in the cases where the non-key fields have the same data in multiple rows.

  • PASS: Bylaw Changes

    - by Bill Graziano
    While you’re reading this, a post should be going up on the PASS blog on the plans to change our bylaws.  You should be able to find our old bylaws, our proposed bylaws and a red-lined version of the changes.  We plan to listen to feedback until March 31st.  At that point we’ll decide whether to vote on these changes or take other action. The executive summary is that we’re adding a restriction to prevent more than two people from the same company on the Board and eliminating the Board’s Officer Appointment Committee to have Officers directly elected by the Board.  This second change better matches how officer elections have been conducted in the past. The Gritty Details Our scope was to change bylaws to match how PASS actually works and tackle a limited set of issues.  Changing the bylaws is hard.  We’ve been working on these changes since the March board meeting last year.  At that meeting we met and talked through the issues we wanted to address.  In years past the Board has tried to come up with language and then we’ve discussed and negotiated to get to the result.  In March, we gave HQ guidance on what we wanted and asked them to come up with a starting point.  Hannes worked on building us an initial set of changes that we could work our way through.  Discussing changes like this over email is difficult wasn’t very productive.  We do a much better job on this at the in-person Board meetings.  Unfortunately there are only 2 or 3 of those a year. In August we met in Nashville and spent time discussing the changes.  That was also the day after we released the slate for the 2010 election. The discussion around that colored what we talked about in terms of these changes.  We talked very briefly at the Summit and again reviewed and revised the changes at the Board meeting in January.  This is the result of those changes and discussions. We made numerous small changes to clean up language and make wording more clear.  We also made two big changes. Director Employment Restrictions The first is that only two people from the same company can serve on the Board at the same time.  The actual language in section VI.3 reads: A maximum of two (2) Directors who are employed by, or who are joint owners or partners in, the same for-profit venture, company, organization, or other legal entity, may concurrently serve on the PASS Board of Directors at any time. The definition of “employed” is at the sole discretion of the Board. And what a mess this turns out to be in practice.  Our membership is a hodgepodge of interlocking relationships.  Let’s say three Board members get together and start a blog service for SQL Server bloggers.  It’s technically for-profit.  Let’s assume it makes $8 in the first year.  Does that trigger this clause?  (Technically yes.)  We had a horrible time trying to write language that covered everything.  All the sample bylaws that we found were just as vague as this. That led to the third clause in this section.  The first sentence reads: The Board of Directors reserves the right, strictly on a case-by-case basis, to overrule the requirements of Section VI.3 by majority decision for any single Director’s conflict of employment. We needed some way to handle the trivial issues and exercise some judgment.  It seems like a public vote is the best way.  This discloses the relationship and gets each Board member on record on the issue.   In practice I think this clause will rarely be used.  I think this entire section will only be invoked for actual employment issues and not for small side projects.  In either case we have the mechanisms in place to handle it in a public, transparent way. That’s the first and third clauses.  The second clause says that if your situation changes and you fall afoul of this restriction you need to notify the Board.  The clause further states that if this new job means a Board members violates the “two-per-company” rule the Board may request their resignation.  The Board can also  allow the person to continue serving with a majority vote.  I think this will also take some judgment.  Consider a person switching jobs that leads to three people from the same company.  I’m very likely to ask for someone to resign if all three are two weeks into a two year term.  I’m unlikely to ask anyone to resign if one is two weeks away from ending their term.  In either case, the decision will be a public vote that we can be held accountable for. One concern that was raised was whether this would affect someone choosing to accept a job.  I think that’s a choice for them to make.  PASS is clearly stating its intent that only two directors from any one organization should serve at any time.  Once these bylaws are approved, this policy should not come as a surprise to any potential or current Board members considering a job change.  This clause isn’t perfect.  The biggest hole is business relationships that aren’t defined above.  Let’s say that two employees from company “X” serve on the Board.  What happens if I accept a full-time consulting contract with that company?  Let’s assume I’m working directly for one of the two existing Board members.  That doesn’t violate section VI.3.  But I think it’s clearly the kind of relationship we’d like to prevent.  Unfortunately that was even harder to write than what we have now.  I fully expect that in the next revision of the bylaws we’ll address this.  It just didn’t make it into this one. Officer Elections The officer election process received a slightly different rewrite.  Our goal was to codify in the bylaws the actual process we used to elect the officers.  The officers are the President, Executive Vice-President (EVP) and Vice-President of Marketing.  The Immediate Past President (IPP) is also an officer but isn’t elected.  The IPP serves in that role for two years after completing their term as President.  We do that for continuity’s sake.  Some organizations have a President-elect that serves for one or two years.  The group that founded PASS chose to have an IPP. When I started on the Board, the Nominating Committee (NomCom) selected the slate for the at-large directors and the slate for the officers.  There was always one candidate for each officer position.  It wasn’t really an election so much as the NomCom decided who the next person would be for each officer position.  Behind the scenes the Board worked to select the best people for the role. In June 2009 that process was changed to bring it line with what actually happens.  An Officer Appointment Committee was created that was a subset of the Board.  That committee would take time to interview the candidates and present a slate to the Board for approval.  The majority vote of the Board would determine the officers for the next two years.  In practice the Board itself interviewed the candidates and conducted the elections.  That means it was time to change the bylaws again. Section VII.2 and VII.3 spell out the process used to select the officers.  We use the phrase “Officer Appointment” to separate it from the Director election but the end result is that the Board elects the officers.  Section VII.3 starts: Officers shall be appointed bi-annually by a majority of all the voting members of the Board of Directors. Everything else revolves around that sentence.  We use the word appoint but they truly are elected.  There are details in the bylaws for term limits, minimum requirements for President (1 prior term as an officer), tie breakers and filling vacancies. In practice we will have an election for President, then an election for EVP and then an election for VP Marketing.  That means that losing candidates will be able to fall down the ladder and run for the next open position.  Another point to note is that officers aren’t at-large directors.  That means if a current sitting officer loses all three elections they are off the Board.  Having Board member votes public will help with the transparency of this approach. This process has a number of positive and negatives.  The biggest concern I expect to hear is that our members don’t directly choose the officers.  I’m going to try and list all the positives and negatives of this approach. Many non-profits value continuity and are slower to change than a business.  On the plus side this promotes that.  On the negative side this promotes that.  If we change too slowly the members complain that we aren’t responsive.  If we change too quickly we make mistakes and fail at various things.  We’ve been criticized for both of those lately so I’m not entirely sure where to draw the line.  My rough assumption to this point is that we’re going too slow on governance and too quickly on becoming “more than a Summit.”  This approach creates competition in the officer elections.  If you are an at-large director there is no consequence to losing an election.  If you are an officer the only way to stay on the Board is to win an officer election or an at-large election.  If you are an officer and lose an election you can always run for the next office down.  This makes it very easy for multiple people to contest an election. There is value in a person moving through the officer positions up to the Presidency.  Having the Board select the officers promotes this.  The down side is that it takes a LOT of time to get to the Presidency.  We’ve had good people struggle with burnout.  We’ve had lots of discussion around this.  The process as we’ve described it here makes it possible for someone to move quickly through the ranks but doesn’t prevent people from working their way up through each role. We talked long and hard about having the officers elected by the members.  We had a self-imposed deadline to complete these changes prior to elections this summer. The other challenge was that our original goal was to make the bylaws reflect our actual process rather than create a new one.  I believe we accomplished this goal. We ran out of time to consider this option in the detail it needs.  Having member elections for officers needs a number of problems solved.  We would need a way for candidates to fall through the election.  This is what promotes competition.  Without this few people would risk an election and we’ll be back to one candidate per slot.  We need to do this without having multiple elections.  We may be able to copy what other organizations are doing but I was surprised at how little I could find on other organizations.  We also need a way for people that lose an officer election to win an at-large election.  Otherwise we’ll have very little competition for officers. This brings me to an area that I think we as a Board haven’t done a good job.  We haven’t built a strong process to tell you who is doing a good job and who isn’t.  This is a double-edged sword.  I don’t want to highlight Board members that are failing.  That’s not a good way to get people to volunteer and run for the Board.  But I also need a way let the members make an informed choice about who is doing a good job and would make a good officer.  Encouraging Board members to blog, publishing minutes and making votes public helps in that regard but isn’t the final answer.  I don’t know what the final answer is yet.  I do know that the Board members themselves are uniquely positioned to know which other Board members are doing good work.  They know who speaks up in meetings, who works to build consensus, who has good ideas and who works with the members.  What I Could Do Better I’ve learned a lot writing this about how we communicated with our members.  The next time we revise the bylaws I’d do a few things differently.  The biggest change would be to provide better documentation.  The March 2009 minutes provide a very detailed look into what changes we wanted to make to the bylaws.  Looking back, I’m a little surprised at how closely they matched our final changes and covered the various arguments.  If you just read those you’d get 90% of what we eventually changed.  Nearly everything else was just details around implementation.  I’d also consider publishing a scope document defining exactly what we were doing any why.  I think it really helped that we had a limited, defined goal in mind.  I don’t think we did a good job communicating that goal outside the meeting minutes though. That said, I wish I’d blogged more after the August and January meeting.  I think it would have helped more people to know that this change was coming and to be ready for it. Conclusion These changes address two big concerns that the Board had.  First, it prevents a single organization from dominating the Board.  Second, it codifies and clearly spells out how officers are elected.  This is the process that was previously followed but it was somewhat murky.  These changes bring clarity to this and clearly explain the process the Board will follow. We’re going to listen to feedback until March 31st.  At that time we’ll decide whether to approve these changes.  I’m also assuming that we’ll start another round of changes in the next year or two.  Are there other issues in the bylaws that we should tackle in the future?

  • AdventureWorks2012 now available for all on SQL Azure

    - by jamiet
    Three days ago I tweeted this: Idea. MSFT could host read-only copies of all the [AdventureWorks] DBs up on #sqlazure for the SQL community to use. RT if agree #sqlfamily — Jamie Thomson (@jamiet) March 24, 2012 Evidently I wasn't the only one that thought this was a good idea because as you can see from the screenshot that tweet has, so far, been retweeted more than fifty times. Clearly there is a desire to see the AdventureWorks databases made available for the community to noodle around on so I am pleased to announce that as of today you can do just that - [AdventureWorks2012] now resides on SQL Azure and is available for anyone, absolutely anyone, to connect to and use* for their own means. *By use I mean "issue some SELECT statements". You don't have permission to issue INSERTs, UPDATEs, DELETEs or EXECUTEs I'm afraid - if you want to do that then you can get the bits and host it yourself. This database is free for you to use but SQL Azure is of course not free so before I give you the credentials please lend me your ears eyes for a short while longer. AdventureWorks on Azure is being provided for the SQL Server community to use and so I am hoping that that same community will rally around to support this effort by making a voluntary donation to support the upkeep which, going on current pricing, is going to be $119.88 per year. If you would like to contribute to keep AdventureWorks on Azure up and running for that full year please donate via PayPal to [email protected]: Any amount, no matter how small, will help. If those 50+ people that retweeted me beforehand all contributed $2 then that would just about be enough to keep this up for a year. If the community contributes more that we need then there are a number of additional things that could be done: Host additional databases (Northwind anyone??) Host in more datacentres (this first one is in Western Europe) Make a charitable donation That last one, a charitable donation, is something I would really like to do. The SQL Community have proved before that they can make a significant contribution to charitable orgnisations through purchasing the SQL Server MVP Deep Dives book and I harbour hopes that AdventureWorks on Azure can continue in that vein. So please, if you think AdventureWorks on Azure is something that is worth supporting please make a contribution. OK, with the prickly subject of begging for cash out of the way let me share the details that you need to connect to [AdventureWorks2012] on SQL Azure: Server mhknbn2kdz.database.windows.net  Database AdventureWorks2012 User sqlfamily Password sqlf@m1ly That user sqlfamily has all the permissions required to enable you to query away to your heart's content. Here is the code that I used to set it up: CREATE USER sqlfamily FOR LOGIN sqlfamily;CREATE ROLE sqlfamilyrole;EXEC sp_addrolemember 'sqlfamilyrole','sqlfamily';GRANT VIEW DEFINITION ON Database::AdventureWorks2012 TO sqlfamilyrole;GRANT VIEW DATABASE STATE ON Database::AdventureWorks2012 TO sqlfamilyrole;GRANT SHOWPLAN TO sqlfamilyrole;EXEC sp_addrolemember 'db_datareader','sqlfamilyrole'; You can connect to the database using SQL Server Management Studio (instructions to do that are provided at Walkthrough: Connecting to SQL Azure via the SSMS) or you can use the web interface at https://mhknbn2kdz.database.windows.net: Lastly, just for a bit of fun I created a table up there called [dbo].[SqlFamily] into which you can leave a small calling card. Simply execute the following SQL statement (changing the values of course): INSERT [dbo].[SqlFamily]([Name],[Message],[TwitterHandle],[BlogURI])VALUES ('Your name here','Some Message','your twitter handle (optional)','Blog URI (optional)'); [Id] is an IDENTITY field and there is a default constraint on [DT] hence there is no need to supply a value for those. Note that you only have INSERT permissions, not UPDATE or DELETE so make sure you get it right first time! Any offensive or distasteful remarks will of course be deleted :) Thank you for reading this far and have fun using AdventureWorks on Azure. I hope it proves to be useful for some of you. @jamiet AdventureWorks on Azure - Provided by the SQL Server community, for the SQL Server community!

  • PASS Summit 2013 Review

    - by Ajarn Mark Caldwell
    As a long-standing member of PASS who lives in the greater Seattle area and has attended about nine of these Summits, let me start out by saying how GREAT it was to go to Charlotte, North Carolina this year.  Many of the new folks that I met at the Summit this year, upon hearing that I was from Seattle, commented that I must have been disappointed to have to travel to the Summit this year after 5 years in a row in Seattle.  Well, nothing could be further from the truth.  I cheered loudly when I first heard that the 2013 Summit would be outside Seattle.  I have many fond memories of trips to Orlando, Florida and Grapevine, Texas for past Summits (missed out on Denver, unfortunately).  And there is a funny dynamic that takes place when the conference is local.  If you do as I have done the last several years and saved my company money by not getting a hotel, but rather just commuting from home, then both family and coworkers tend to act like you’re just on a normal schedule.  For example, I have a young family, and my wife and kids really wanted to still see me come home “after work”, but there are a whole lot of after-hours activities, social events, and great food to be enjoyed at the Summit each year.  Even more so if you really capitalize on the opportunities to meet face-to-face with people you either met at previous summits or have spoken to or heard of, from Twitter, blogs, and forums.  Then there is also the lovely commuting in Seattle traffic from neighboring cities rather than the convenience of just walking across the street from your hotel.  So I’m just saying, there are really nice aspects of having the conference 2500 miles away. Beyond that, the training was fantastic as usual.  The SQL Server community has many outstanding presenters and experts with deep knowledge of the tools who are extremely willing to share all of that with anyone who wants to listen.  The opening video with PASS President Bill Graziano in a NASCAR race turned dream sequence was very well done, and the keynotes, as usual, were great.  This year I was particularly impressed with how well attended were the Professional Development sessions.  Not too many years ago, those were very sparsely attended, but this year, the two that I attended were standing-room only, and these were not tiny rooms.  I would say this is a testament to both the maturity of the attendees realizing how important these topics are to career success, as well as to the ever-increasing skills of the presenters and the program committee for selecting speakers and topics that resonated with people.  If, as is usually the case, you were not able to get to every session that you wanted to because there were just too darn many good ones, I encourage you to get the recordings. Overall, it was a great time as these events always are.  It was wonderful to see old friends and make new ones, and the people of Charlotte did an awesome job hosting the event and letting their hospitality shine (extra kudos to SQLSentry for all they did with the shuttle, maps, and other event sponsorships).  We’re back in Seattle next year (it is a release year, after all) but I would say that with the success of this year’s event, I strongly encourage the Board and PASS HQ to firmly reestablish the location rotation schedule.  I’ll even go so far as to suggest standardizing on an alternating Seattle – Charlotte schedule, or something like that. If you missed the Summit this year, start saving now, and register early, so you can join us!

  • PASS Summit 2010 Recap

    - by AjarnMark
    Last week I attended my eighth PASS Summit in nine years, and every year it is a fantastic event!  I was fortunate my first year to have a contact (Bill Graziano (blog | Twitter) from SQLTeam) that I was expecting to meet, and who got me started on a good track of making new contacts.  Each year I have made a few more, and renewed friendships from years past.  Many of the attendees agree that the pure networking opportunities are one of the best benefits of attending the Summit.  And there’s a lot of great technical stuff, too, some of the things that stick out for me this year include… Pre-Con Monday: PowerShell with Allen White (blog | Twitter).  This was the first time that I attended a pre-con.  For those not familiar with the concept, the regular sessions for the conference are 75-90 minutes long.  For an extra fee, you can attend a full-day session on a single topic during a pre- or post-conference training day.  I had been meaning for several months to dive in and learn PowerShell, but just never seemed to find (or make) the time for it, so when I saw this was one of the all-day sessions, and I was planning to be there on Monday anyway, I decided to go for it.  And it was well worth it!  I definitely came out of there with a good foundation to build my own PowerShell scripts, plus several sample scripts that he showed which already cover the first four or five things I was planning to do with PowerShell anyway.  This looks like the right tool for me to build an automated version of our software deployment process, which right now contains many repeated steps.  Thanks Allen! Service Broker with Denny Cherry (blog | Twitter).  I remembered reading Denny’s blog post on Using Service Broker instead of Replication, and ever since then I have been thinking about using this to populate a new reporting-focused Data Repository that we will be building in the near future.  When I saw he was doing this session, I thought it would be great to get more information and be able to ask the author questions.  When I brought this idea back to my boss, he really liked it, as we had previously been discussing doing nightly data loads, with an option to manually trigger a mid-day load if up-to-the-minute data was needed for something.  If we go the Service Broker route, we can keep the Repository current in near real-time.  Hooray! DBA Mythbusters with Paul Randal (blog | Twitter).  Even though I read every one of the posts in Paul’s blog series of the same name, I had to go see the legend in person.  It was great, and I still learned something new! How to Conduct Effective Meetings with Joe Webb (blog | Twitter).  I always like to sit in on a session that Joe does.  I met Joe several years ago when both he and Bill Graziano were on the PASS Board of Directors together, and we have kept in touch.  Joe is very well-spoken and has great experience with both SQL Server and business.  And we could certainly use some pointers at my work (probably yours, too) on making our meetings more effective and to run on-time.  Of course, now that I’m the Chapter Leader for the Professional Development virtual chapter, I also had to sit in on this ProfDev session and recruit Joe to do a presentation or two for the chapter next year. Query Optimization with David DeWitt.  Anyone who has seen Dr. David DeWitt present the 3rd keynote at a PASS Summit over the last three years knows what a great time it is to sit and listen to him make some really complicated and advanced topic easy to understand (although it still makes your head hurt).  It still amazes me that the simple two-table join query from pubs that he used in his example can possibly have 22 million possible physical query plans.  Ouch! Exhibit Hall:  This year I spent more serious time in the exhibit hall than any year past.  I have talked my boss into making a significant (for us) investment in monitoring tools next year, and this was a great opportunity to talk with all the big-hitters.  Readers of mine may recall that I fell in love with the SQL Sentry Power Suite several months ago and wrote a blog entry about it just from the trial version.  Well as things turned out, short-term budget priorities shifted, and we weren’t able to make the purchase then.  I have it in the budget for next year, but since I was going to the Summit, my boss wanted me to look at the other options to see if this was really the one that we wanted.  I spent a couple of hours talking with representatives from Red-Gate, Idera, Confio, and Quest about their offerings, and giving them each the same 3 scenarios that I wanted to be able to accomplish based on the questions and issues that arise in our company.  It was interesting to discover the different approaches or “world view” that each vendor takes to the subject of performance monitoring and troubleshooting.  I may write a separate article that goes into this in more depth, but the product that best aligned with our point of view, and met the current needs we have is still the SQL Sentry Power Suite.  I’m not saying that the others are bad or wrong or anything like that, just that the way they tackled the issue did not align as well with our particular needs as does SQL Sentry’s product.  And that was something I learned too, when you go shopping for these products, you really need to know what you want to get from them.  It’s best if you have a few example scenarios from work that you can use to test out how well each tool fits your particular needs. Overall, another GREAT event.  I can’t wait to get the DVDs so I can sit in on a bunch of other sessions that I couldn’t get to because I was in one of the ones above.  And I can hardly wait until next year!

  • How to pass results of bc to a variable

    - by shaolin
    I'm writing a script and I would like to pass the results from bc into a variable. I've declared 2 variables (var1 and var2) and have given them values. In my script I want to pass the results from bc into another variable say var3 so that I can work with var3 for other calculations. So far I have been able write the result to a file which is not what I'm looking for and also I've been able to echo the result in the terminal but I just want to pass the result to a variable at moment so that I can work with that variable. echo "scale=2;$var1/var2" | bc

  • Windows Server 2008 / SQL 2008 Licensing for Authenticated Web Application

    - by MikeM
    Hello, I'm trying to crunch some numbers to see what the software costs involved are for hosting an application we are developing. Users will not be anonymous - they will need to log in. SQL Server 2008: SQL Server licensing is easy - it will be licensed per-processor. No real fuss there. The cost of CALs would be much higher for the number of users as compared to the processor licenses. Windows Server 2008: This is where it gets trickier. We need to license the OS for both the web servers (there will be a couple) plus the database servers (also a couple). The Web Servers could run on the Web Edition without a need for CALs, but if you continue reading, you will see that may not matter much because I will likely have user CALs for each user anyway. We can't use the "External Connector" for any of the Windows licenses, because that doesn't cover customers who are paying to access a hosted application. We can't use the Web Edition for the SQL Servers because that license only allows database running on Web Edition to host data for the local web application (i.e. other web servers can't connect to it). So that leaves us with the "full" editions of Windows Server for the database server OS. I find this a little rediculous, and I feel as though I must be missing something, but it looks to me like I will actually need to buy a CAL for every user who signs up to use our service. I feel like I'm missing something because that means that for every user, I have to shell out $40 for a CAL. That could be one or two years' worth of revenue from each user for an inexpensive service! Is there any way to serve a web application to authenticated users without paying for individual Windows Server CALs, if the web servers and SQL servers are seperate boxes?

  • Installing SQL Server 2008 on Windows 7 64-bit

    - by harriyott
    I'm having a shocking time trying to install SQL Server 2008 on 64-bit Windows 7. When I run setup.exe, I get the following error message: Microsoft .NET Framework 3.5 installation has failed. SQL Server 2008 Setup requires .NET Framework 3.5 to be installed Things I've tried: I've checked and double checked. I do have .NET Framework 3.5 installed, with SP1 I've read about a missing Windows Installer 4.5 installation producing the same error. Win7 comes with Windows Installer 5, which hopefully satisfies this requirement, as I've tried to install 4.5 and it won't let me Burning the ISO to DVD and installing from there. Installing on an XP machine using the same ISO. This works, so the ISO must be fine. Considering SQL Server 2005, but it really needs to be 2008 for the project. Update Creating a slipstream version gives the same error Update I could install SQL Server Express, and then SP1, but couldn't upgrade to Enterprise. If you've come across this issue, or know how to fix it, I'd love to know.

  • Unable to back up SQL Server databases using a maintenance plan

    - by Diogo Lopes
    I am trying to create a maintenance plan that will run automatically and back up my SQL Server 2005 databases automatically. I create a new maintenance plan and add a "Back Up Database Task", select all User databases, and choose a path to back up to. IMAGE in http://www.freeimagehosting.net/uploads/16be7dce43.jpg [new user limitation] When I save and try to execute this plan, I get the following error message: =================================== Execution failed. See the maintenance plan and SQL Server Agent job history logs for details. =================================== Job 'Backup.Subplan_1' failed. (SqlManagerUI) I've checked the maintenance plan log, the agent log, and just about every log file I can find and there are no entries at all to help me figure out why this is failing. If I right-click on a specific database and select "Back Up", the task succeeds. I tried changing the plan to back up just that one database and it still failed. I've tried running the plan with both Windows authentication and SQL Server authentication with the sa account. I also tried specifically granting the SQL Server Agent user account full privileges on the backup folder, but it still failed. Thanks for any suggestions!

  • How to get rank from full-text search query with Linq to SQL?

    - by Stephen Jennings
    I am using Linq to SQL to call a stored procedure which runs a full-text search and returns the rank plus a few specific columns from the table Article. The rank column is the rank returned from the SQL function FREETEXTTABLE(). I've added this sproc to the data model designer with return type Article. This is working to get the columns I need; however, it discards the ranking of each search result. I'd like to get this information so I can display it to the user. So far, I've tried creating a new class RankedArticle which inherits from Article and adds the column Rank, then changing the return type of my sproc mapping to RankedArticle. When I try this, an InvalidOperationException gets thrown: Data member 'Int32 ArticleID' of type 'Heap.Models.Article' is not part of the mapping for type 'RankedArticle'. Is the member above the root of an inheritance hierarchy? I can't seem to find any other questions or Google results from people trying to get the rank column, so I'm probably missing something obvious here.

  • Calling SQL Azure's stored procedure in silverlight

    - by sweetsweet
    I have a silverlight application to call the SQL Azure's stored procedure and show the data. I use the service to call stored procedure, and it is working when it is run at VS 2008. But when I integrate in php page, the data is not shown. I think the service is not running. How can I call SQL Azure stored procedure without using service? I cannot use ADO.Net Entity Domain Model and LINQ to SQL(I don't have permission to access that database in GUI). I cannot connect to SQL Azure, so which method can I use to call SQL Azure stored procedure in silverlight? Please give me the information. {I don't know very much about that silverlight. To take the detailes of my project. I want to call SQL Azure's stored procedure. So, I tried to call that Stored Procedure from ADO.Net Entity Domain Model. The problem is I cannot access that SQL Azure database. It show "Buit_in function suer_sname is not supported in this version of SQL server. Therefore, I connect to that Stored Procedure in code beind and call that function in Service and to use that data in presentation layer, I add service reference in silverlight(I mean the service is at the same project). It is perfectly working when it is running at VS. So,I take out xap file and call that xap file in php. The silverlight is running in that PHP page but the data is not shown. I think the service is not hosted. So, how can I solve my problem? I use xampp to run my php page. }

  • sql server 2008 cluster hang when a heavy load is run

    - by Billy OT
    we have a sql server 2008 active/active cluster running on wondows 2008R2 O/S. 14GB RAM, 4xCPU. we have set a ceiling of 12GB for sql server. We're running an agent job which loads 3 million records to a database. during this load the job fails and the cluster seems to attempt to fail over to the other node but unsuccessfully i.e., the cluster address is no longer accessible. we have to manually fail the cluster node back. during the load on viewing task manager we can see that memory usage hits a max of 12.5GB and CPU at times hits 100% on all 4 CPU, but for the most part fluctuates at an average of about 60%. I suppose my question is, will a cluster try to fail over if memory or CPU are taking a heavy hit? or am i barking up the wrong tree? also any ideas why it wouldn't fully fail over? we've crawled through logs, of which there are a lot, and can't find anything useful. we've also tried recreating the issue but it ran successfully at a later time. Also 3 million rows doesn't seem like a lot but in terms of resources should 14GB RAM and 4xCPU not be sufficient? Further information on this, we ran the load again today and corrupted the database! We received the error message : LogWriter: Operating system error 170. It looks like, under the heavy load, the sql cluster attempted to fail over and in doing so migrated a lun (or drive) which meant the disk was no longer reachable. (this is just our theory). The database is now 'suspect' and requiring restoration. The 170 error above also indicates that on failing over to the other node, the sql service could not start as it was already in use, therefore it couldn't fail over fully?? But I'm wondering why would it need to fail over in the first place? My assumptions could be completely wrong on this, so any ideas would be appreciated.

  • Can't add service account to domain group during SQL cluster install

    - by Sam
    I'm installing a 2008 instance on a Server 2003 machine which is already running SQL 2005. I need to set up domain groups for the security setup step: http://msdn.microsoft.com/en-us/library/ms179530.aspx On Windows Server 2003, specify domain groups for SQL Server services. All resource permissions are controlled by domain-level groups that include SQL Server service accounts as group members. Much more info on this here: http://support.microsoft.com/kb/910708 I've had problems with being able to add the windows service accounts to the groups at install time. The security admins had to make my account a domain admin - which they were hesitant to do. The account under which SQL Server Setup is running must have permissions to add accounts to the domain groups. Is there a specific security setting which would allow my account to add accounts to a group? UPDATE: I'm looking for specific instructions. I have a global group called domain\servicegroup - what do I tell the security folks to do. I'd love to figure it out myself, but I don't have access to this stuff.
