  • SQL Import to update existing records?

    - by Kenundrum
    I've got a table in a database that contains costs for items that gets updated monthly. To update these costs, we have someone export the table, do some magic in excel, and then import the table back to the database. We're running MSSQL 2005 and using the built in SQL Management Studio. The problem is that when importing back into the table, we have to delete all the records before we import or else we'll get errors. The ideal situation would be for the import to recognize the primary keys and then update the records instead of trying to create a second record with a duplicate key- halting the import. The best illustration of the behavior we're trying to get can be found at http://sqlmanager.net/en/products/mssql/dataimport/documentation/hs2180.html the update or insert example. Is something like this possible with the built in tools or do we have to get third party software to make it happen?

  • Changing an MSSQL clustered index field from containing "random" GUIDs to sequential GUIDs - how wil

    - by Eyvind
    We have an MSSQL database in which all the primary keys are GUIDs (uniqueidentifiers). The GUIDs are produced on the client (in C#), and we are considering changing the client to generate sequential (comb) GUIDs instead of just using Guid.NewGuid(), to improve db performance. If we do this, how will this affect installations that already have data with "random" GUIDs as clustered PKs? Can anything be done (short of changing all the PK values) to rebuild the indexes to avoid further fragmentation and bad insert performance? Please give explicit and detailed answers if you can; I am a C# developer at heart and not all too familiar with all the intricacies of SQL Server. Thanks!

  • MSSQL Backup Question

    - by MJ
    I'm currently taking over for someone who was in charge of backing up over 250 servers on different platforms, until we hire a replacement. The main question I have is: If we use a backup software, such as Symantec backup exec, does this perform the correct backup for MSSQL Server? I was listening to Stack Overflow Podcast, and I heard them talk about you cannot just backup the SQL data files, but you also need the transaction log? So, if we just backup the whole machine, would we be able to recover it correctly, since we would be backing up the data file and the log? Thanks!

  • How to schedule daily backup in MSSQL Server 2008 Web Edition

    - by Xenon
    In MSSQL Management Studio I created a maintenance plan but it won't work Error is; "Message Executed as user: LITESPELL-19C34\Administrator.

  • Migrate Data and Schema from MySQL to MSSQL

    - by colithium
    Are there any free solutions for automatically migrating a database from MySQL to MSSQL Server that "just works"? I've been attempting this simple (at least I thought so) task all day now. I've tried: MSSQL Server Management Studio's Import Data feature Create an empty database Tasks - Import Data... .NET Framework Data Provider for Odbc Valid DSN (verified it connects) Copy data from one or more tables or views Check 1 VERY simple table Click Preview Get Error: The preview data could not be retrieved. ADDITIONAL INFORMATION: ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.1.45-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"table_name"' at line 1 (myodbc5.dll) A similar error occurs if I go through the rest of the wizard and perform the operation. The failed step is "Setting Source Connection" the error refers to retrieving column information and then lists the above error. It can retrieve column information just fine when I modify column mappings so I really don't know what the issue is. I've also tried getting various MySql tools to output ddl statements that MSSQL understand but haven't succeeded. I've tried with MySQL v5.1.11 to SQL Server 2005 and with MySQL v5.1.45 to SQL Server 2008 (with ODBC drivers 3.51.27.00 and 5.01.06.00 respectively)

  • Equivalent of phpMyAdmin for MSSQL?

    - by Tedd Hansen
    Is there any webinterface for administrating MSSQL similar to phpMyAdmin (for MySQL)? I want a self-service setup where developers can create a database through webinterface and upload/download backups of the database without local access. I've considered phpMSAdmin, but it hasn't had a release since 2006 so I'm not sure its worth the effort of setting it up. If there is something else (free or not-so-free) that would be great. My question is similar to this one posted 2 years ago, but no good webinterface was found back then. SQL Web Data Administrator seems interesting, but it lacks a few features - most notably creating new databases (also, not updated since 2007).

  • Windows, Apache and MSSQL Authentication

    - by user1114330
    I have a create database script written in perl. I remember it working just fine another machine. A couple years later using a Vista machine I am trying to use it again and it keeps failing. The main difference is that now I am using Apache instead of IIS. In the script the IUSR account is granted permissions as it needs to write to the database as a part of another program. IIS has been uninstalled on this machine but the IUSR account still exists. The NT AUTHORITY\IUSR is also seen in the logins drop down in MSSQL(2012). The machine is running Vista Home Edition. However when running the script I get errors that say that NT AUTHORITY\IUSR cannot be found. I tried also with COMPUTERNAME\IUSR just for the heck of it and of course it was not found. I also tried with IUSR alone and for some reason the user isn't being "found"? Any ideas?

  • MSSQL 2012 Error 26 and remote connection

    - by Rayfloyd
    I'm trying to set up MSSQL 2012 for a school project and I need to be able to connect to it remotely as my teammates will also be working on it. I did a clean install of SQL Server 2012 Express. Knowing I can't connect remotely straight off, I tweaked the settings that needed tweaking according to the internet. What I did 1.Made sure remote connections were allowed 2.Enabled TCP/IP 3.Removed 0s from Dynamic ports and set 1433 in TCP Port 4.Enabled Named Pipes 5.Created Outbound and Inbound traffic rules in the firewall for TCP port 1433 and UDP port 1434 6.Port forwarded 1433 to my "server" and 1434 too 7.made sure I was pingable 8.SQL Server authentication is enabled 9.I have restarted my computer so that changes to the config are saved So whenever I try to connect using management studio on another computer than the server using myusername.dyndns.org\SQLEXPRESS I get error 26 I have been searching for different solutions for 3 hours with no luck.

  • How to force a drop of MSSQL Server database

    - by ng01
    I am trying to delete an MSSQL Server database, however I am having no luck. I have tried multiple things such as user ALTER DATABASE my_database SET RESTRICTED_USER WITH ROLLBACK IMMEDIATE; GO DROP DATABASE my_database; GO I have also tried to right click on it a delete it. This does not work, it tells me "Cannot drop database "ima_debts" because it is currently in use". The thing is there is definately no other user connected to it. In fact I disabled TCP/IP for the database and restarted it. Not even "Microsoft SQL Server Management Studio (Administrator)" is connected to it. I have made sure to login to "master". Why is it telling me it is currently in use. Is it possible for me to delete perhaps a directory or something from the file system to get rid of this database? Any help would be appreciated. Thanks.

    We have seen some increase in activity with more people downloading our driver and either reporting their successes or reporting any issues they run into – for the native driver (sqlsrv_xxxx API) to the PDO driver (PDO API). We’d like to thank you all for your effort and hope that our responses were quick enough as well as accurate. To keep things simple, let us call the former the SQLSRV-PHP extension (php_sqlsrv.dll) whereas the latter will be the SQLSRV-PDO extension (php_pdo_sqlsrv...(read more)

  • Incremental Statistics Maintenance – what statistics will be gathered after DML occurs on the table?

    - by Maria Colgan
    Incremental statistics maintenance was introduced in Oracle Database 11g to improve the performance of gathering statistics on large partitioned table. When incremental statistics maintenance is enabled for a partitioned table, oracle accurately generated global level  statistics by aggregating partition level statistics. As more people begin to adopt this functionality we have gotten more questions around how they expected incremental statistics to behave in a given scenario. For example, last week we got a question around what partitions should have statistics gathered on them after DML has occurred on the table? The person who asked the question assumed that statistics would only be gathered on partitions that had stale statistics (10% of the rows in the partition had changed). However, what they actually saw when they did a DBMS_STATS.GATHER_TABLE_STATS was all of the partitions that had been affected by the DML had statistics re-gathered on them. This is the expected behavior, incremental statistics maintenance is suppose to yield the same statistics as gathering table statistics from scratch, just faster. This means incremental statistics maintenance needs to gather statistics on any partition that will change the global or table level statistics. For instance, the min or max value for a column could change after just one row is inserted or updated in the table. It might easier to demonstrate this using an example. Let’s take the ORDERS2 table, which is partitioned by month on order_date.  We will begin by enabling incremental statistics for the table and gathering statistics on the table. After the statistics gather the last_analyzed date for the table and all of the partitions now show 13-Mar-12. And we now have the following column statistics for the ORDERS2 table. We can also confirm that we really did use incremental statistics by querying the dictionary table sys.HIST_HEAD$, which should have an entry for each column in the ORDERS2 table. So, now that we have established a good baseline, let’s move on to the DML. Information is loaded into the latest partition of the ORDERS2 table once a month. Existing orders maybe also be update to reflect changes in their status. Let’s assume the following transactions take place on the ORDERS2 table this month. After these transactions have occurred we need to re-gather statistic since the partition ORDERS_MAR_2012 now has rows in it and the number of distinct values and the maximum value for the STATUS column have also changed. Now if we look at the last_analyzed date for the table and the partitions, we will see that the global statistics and the statistics on the partitions where rows have changed due to the update (ORDERS_FEB_2012) and the data load (ORDERS_MAR_2012) have been updated. The column statistics also reflect the changes with the number of distinct values in the status column increase to reflect the update. So, incremental statistics maintenance will gather statistics on any partition, whose data has changed and that change will impact the global level statistics.

  • How to manage and improve web application with 50 customers?

    - by Muhammet Göktürk Ayan
    First of all, sorry for my English. We've developed a Web Application using ASP.NET and Sql Server. We've started selling it and of course are still continually improving and developing it. The question is, how do we go about updating each client's version of the site? We have, maybe, 50 customers. 50 different folders and 50 different db's sounds like a bad idea. Is there any known method for solving this kind of scenario? For Explain: We are developing a Crm, for 50 companies. They will have 10 users maybe. It makes 500 users and their customers and products.

  • What can I do to make sure my code gets maintained in a developer light environment?

    - by asjohnson
    I am a contract data analyst, so I bounce between jobs every 3-6 months, which I find to be a good fit for me, but it leads to some problems when it comes to coding. I mostly do statistics (I've asked a similar question on cross validated, but the answers there are not relevant here), but I have also found out that the business world loves excel and loves copying and pasting the same thing over and over again even more. This led me to learn how to write VBA scripts and then VB.NET programs to automate as many of these reports as I can. I am certain my programs are not the most elegant, but I put a good bit of effort into making sure they work under as many cases as I can test, I add in exceptions and try to code so the program can handle changes in the files that it processes, but there is a limit, if you remove a huge portion of the data, there is a good chance my program is going to trip up, which I accept will inevitably happen. Usually a pretty minor change in the code fixes the problem and I do try and comment my code and make it readable under the assumption that some other person will have to read it some day. My problem is that I generally get put on teams of folks with essentially no experience with programming (like VBA would be a huge stretch for anyone I work directly with). I am wondering what I should be doing as the person that wrote the code to do my best to keep it maintained. I have two approaches in mind (outlined next), but would be very happy to get any advice. Solution 1: Find the more tech savvy coworkers and run them through the programs and what basic changes can be made. Honestly automating excel is about as easy as it can get when it comes to programming, so I feel like I could teach someone the basics of maintaining it pretty quick. Solution 2: Get in touch with the IT department and show them what is going on and maybe they will be able to help. The problem here is that the IT department is constantly swamped (as I'm sure many of you know) and I feel like kind of a jerk for dumping more things on them. I do leave my personal email address with places and am willing to answer quick questions via email, but I view the need for more exhaustive maintenance as something of an inevitability and would like to make sure I do my due diligence to make sure it gets done. I imagine some combination of the two approaches outlined there, but is there any kind of heads up I should give IT? I feel like I would be annoyed if I started getting requests to fix a program that I had never seen from some random guy that is no longer there.

  • How to deal with transactions when creating a database connection for each query

    - by webnoob
    In line with this post here I am going to change my website to create a connection per query to take advantage of .NET's connection pooling. With this in mind, I don't know how I should deal with transactions. At the moment I do something like (psuedo code): GlobalTransaction = GlobalDBConnection.BeginTransaction(); try { ExecSQL("insert into table ..") ExecSQL("update some_table ..") .... GlobalTransaction.Commit(); }catch{ GlobalTransaction.Rollback(); throw; } ExecSQL would be like this: using (SqlCommand Command = GlobalDBConnection.CreateCommand()) { Command.Connection = GlobalDBConnection; Command.Transaction = GlobalTransaction; Command.CommandText = SQLStr; Command.ExecuteNonQuery(); } I'm not quite sure how to change this concept to deal with transactions if the connection is created within ExecSQL because I would want the transaction to be shared between both the insert and update routines.

  • Maintenance window and recovery for a large database

    - by NYSystemsAnalyst
    One of our teams is developing a database that will be somewhat large (~500GB) and grow from there (I know 500 Gigs may seem small to many of you, but it will be one of the larger databases in our shop). One of the issues they are grappling with is backing up and restoring the database. Basically, the database will have several "data" tables and one table used for storing images / documents. We need to accomplish the following: Be able to quickly backup and restore only the data tables (sans images) to our test server for debugging and testing purposes. In the event of a catastrophic database failure, restore the data tables only to get most of the application up and running ASAP. Then, restore the images table when possible. Backup the database within the allotted nightly time window (a few hours). My questions are: Is it possible to accomplish the first two goals while still having the images stored in the same database? If so, would we use filegroups, filestream, or something else? How do other shops backup their databases in a reasonable time window while maintaining high availability? Do you replicate to a second server and backup from there?

  • powershell vs GPO for installation, configuration, maintenance

    - by user52874
    My question is about using powershell scripts to install, configure, update and maintain Windows 7 Pro/Ent workstations in a 2008R2 domain, versus using GPO/ADMX/msi. Here's the situation: Because of a comedy of cumulative corporate bumpfuggery we suddenly found ourselves having to design, configure and deploy a full Windows Server 2008R2 and Windows 7 Pro/Enterprise on very short notice and delivery schedule. Of course, I'm not a windows expert by any means, and we're so understaffed that our buzzword bingo includes 'automate' and 'one-button' and 'it needs to Just Work'. (FWIW, I started with DEC, then on to solaris and cisco, then linux of various flavors with a smattering of BSD nowadays. I use Windows for email and to fill out forms). So we decided to bring in a contractor to do this for us. and they met the deadline. The system is up and mostly usable, and this is good. We would not have been able to do this. But it's the 'mostly' part that is proving to be the PIMA now, and I'm having to learn Microsoft stuff anyway until/if we can get a new contract with these guys for ongoing operations. Here's my question. The contractor used powershell almost exclusively for deployment, configuration and updating. My intensive reading over the last week leads me to think that the generally accepted practices for deployment, configuration and updating microsoft stuff uses elements of GPOs and ADMX templates, along with maybe some third party stuff like PolicyPak. Are there solid reasons that I've not found yet that powershell scripts would be preferred over the GPO methods? I'm going to discuss this with the contractor lead when he gets back from his vacation, and he'll be straight with me (nor do I think they set us up). But I can also see this might be a religious issue, so I would still like some background on this. Thoughts? or weblinks? Thanks!

  • Oracle vocabulary, what is the mysql/mssql equivalent of a database

    - by jeph perro
    Hi, I need some help with vocabulary, I don't use Oracle that often but I am familiar with MySQL and MSSQL. I have an application I need to upgrade and migrate, and part of the procedure to do that involves exporting to an XML, create new database tables, then populate the new database tables from the XML export. In Oracle, my database connection specifies a username, password, and an SID. This SID contains tables belonging to several applications. My question is: Can I re-use the same user to create the new tables ( with the same names ). In MySQL or MSSQL, I would create a new database and grant my user privileges to create tables in it. OR, do I need to create a new database user for my upgraded tables?

  • custom MSSQL driver

    - by hoodoos
    I had a crazy thought about writing my own MSSQL driver to make it work something like non-blocking http client, so it won't be thread thirsty and could handle lots of db queries within one thread. I tried to look over google for some guidelines about implementing MSSQL client protocol, but found none really, where do those guys get information about it when they write own implementations for PHP or python? I need a really low level to be documented so I can implement all phases of working with a connection through sockets. And would be really nice to have a an example in c# langauge. :)

  • Problems with sp_addlinkedserver in MSSQL 2000

    - by manneorama
    Hi! I'm having a bit of a problem with moving specific data from one server running MSSQL 2000 (A) and another running MSSQL 2008 (B). I'm writing a script according to customer specifications which is to be executed on A, populating tables in B with data. However, I can't seem to get the server link to work. -- Bunch of declarations here EXEC sp_addlinkedserver @server = @ServerName, @srvproduct = @ServerProduct, @provider = @ProviderString, @datasrc = @RemoteHost -- Data migration stuff here EXEC sp_dropserver @ServerName Now if I run the script in its entirety I get an error saying: Msg 7202, Level 11, State 2, Line 55 Could not find server 'remoteServer' in sysservers. Execute sp_addlinkedserver to add the server to sysservers. However, if I higlight only the sp_addlinkedserver-part and execute that, there is no error and I can highlight the rest of the script and run it. What am I missing here? Please help! PS. If backup-restore was an option, I would have done that already.
