  • SQL Server replication - how to sync tables from internal database to read-only website database

    - by frankadelic
    I have an internal SQL Server 2005 database "ADMIN_DATA" that is used by admin users. We would like to sync three of the database tables in ADMIN_DATA out to another SQL Server 2005 database "WEB_DATA", which is used by a public web app. WEB_DATA is read-only - only SELECT statements are allowed, while ADMIN_DATA is updated all the time. What is the best solution? How can this be accomplished with minimal custom coding and/or changes to database tables? Notes: ADMIN_DATA and WEB_DATA are different physical machines and on different subnets. The syncing operation doesn't need to be instantaneous.

  • SQL SERVER – Beginning New Weekly Series – Memory Lane – #001

    - by pinaldave
    I am introducing a new series today.  This series is called “Memory Lane.”  From the last six years and 2,300 articles, there are fantastic articles I keep revisiting.  Sometimes when I read old blog posts I think I should have included something or added a bit more to the topic.  But for many articles, I still feel they are fantastic (even after six years) and could be read again and again. I have also found that after six years of blogging, readers will write to me and say “Pinal, why don’t you write about X, Y or Z.”  The answer is: I already did!  It is here on the blog, or in the comments, or possibly in one of my books.  The solution has always been there, it is simply a matter of finding it and presenting it again.  That is why I have created Memory Lane.  I will be listing the best articles from the same week of the past six years.  You will find plenty of reading material every Saturday from articles of SQLAuthority past. Here is the list of curetted articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2006 Query to Display Foreign Key Relationships and Name of the Constraint for Each Table in Database My blogging journey began with this blog post. As many of you know my journey began with creating a repository of my scripts. This was very first script which I had written to find out foreign key relationship and constraints. The same query was updated later on using the new SYS schema modification in SQL Server. Version 1: Using sys.schema Version 2: Using sys.schema and additional columns 2007 Milestone Posts – 1 Year (365 blogs) and 1 Million Views When I reached 1st week of Nov in 2007 SQLAuthority.com blog had around 365 blog posts and 1 Million Views. I was not obsessed with the statistics before but this was indeed an interesting moment for me as I was blogging for myself and did not realize that so many people are reading my blog. In year 2006 there were not many bloggers so blogging was new to me as well. I was learning it as I go. 2008 Stored Procedure WITH ENCRYPTION and Execution Plan If you have stored procedure and its code is encrypted when you execute it what will be displayed in the execution plan. There are two kinds of execution plans 1) Estimated and 2) Actual. It will be indeed interesting to know what is displayed in both the cases when Stored Procedure is encrypted. What is your guess? Now go ahead and click on here and figure out your answer. If the user is not able to login into SQL Server due to any error or issues there were two different blog post addresses the same issue here and here. 2009 It seems like Nov is the month of SQLPASS month. In 2009 on the same week I was in USA attending SQLPASS event. I had a fantastic experience attending the event. Here are the blog posts covering the subject Day 1, Day 2, Day 3, Day 4 2010 Finding the last backup time for all the databases This little script is very powerful and instantly gives details when was the last time your database backup performed. If you are reading this blog post – I say just go ahead and check if everything is alright on your server and you have all the necessary latest backup. It is better to be safe than sorrow. Version 1: Above script was improved to get more details about the database Version 2: This version of the script will include pretty much have all the backup related information in a single script. Do not miss to save it for future use. Are you a Database Administrator or a Database Developer? Three years ago I created a very small survey and the results which I have received are very interesting. The question was asking what is the profile of the visitor of that blog post and I noticed that DBA and Developers have balanced with little inclination towards Developers. Have you voted so far? If not, go ahead! 2011 New Book Released – SQL Server Interview Questions And Answers One year ago, on November 3, 2011 I published my book SQL Server Interview Questions and Answers.  The book has a lot of great reviews, and we have even received emails telling us this book was a life changer because it helped get them a great new job.  I don’t think anyone can get a job just from my book.  It was the individual who studied hard and took it seriously, and was determined to learn something new.  The book might have helped guide them and show them the topics to study, but they spent their own energy on it.  It was their own skills that helped them pass the exam. So, in this very first installment, I would like to thank the readers for accepting our book, for giving it great reviews and for using it and sharing it.  Our goal in writing this book was to help others, and it seems like we succeeded.

  • Problem with apt-get update on ubuntu server

    - by Ben
    I have ubuntu 32 bit 12.04 server edition but i am having issues with apt-get updating. The server is able to ping the outside world (both 8.8.8.8 and www.google.com) but when I attempt to sudo apt-get update the first bit works but then I get this: If i attempt to check or autoclean with: sudo apt-get check I get this: I have tried the fix detailed here: How do I fix a "Problem with MergeList" error when trying to do an update? But it does not work, the same thing occurs again. Any suggestions? PS. The server is a fresh install, no external programs have been added. EDIT: We have tried using different sources, both aarnet and au.archive sources were tried.

  • SQL Server 2008 database mirroring madness

    - by Dmitri Nesteruk
    I'm trying to get database mirroring to work on SQL Server 2008 between two computers. I checked connectivity, but here's what I end up with: on the principal machine, the server can connect to the mirror but refuses to set up a mirroring partnership due to it being 'unable to connect' (I checked connectivity, everything works). The weird thing has happened on the mirror. First, the mirror now thinks it's being mirrored. Second, after I delete and recover the mirrored database, it goes into Restoring... mode and just gets stuck there. Any ideas you might have on this are appreciated. Thanks!

  • Database security / scaling question

    - by orokusaki
    Typically I use a database such as MySQL or PostGreSQL on the same machine as the application using it, which makes access easy and secure. I'm just now building the first site that will have a separate physical database server (later this year it will). I'm wondering 3 things: (security) What things should I look into for starters pertaining to security of accessing a separate machine's database? (scalability) Are their scalability issues that I should think about pertaining to this (technology agnostic)? (more ServerFaultish but related) If starting the DB out on the same physical server (using a separate VMWare VM) and later moving to a different physical server, are there implicit problems that I'll have to deal with? Isn't another VM still accessed via localhost? If these questions are completely ludicrous, I apologize to you DB experts.

    - by GameBuilder
    Hi I have developed a game on android.Now I want to play it on wifi or 3G. I have game packets which i want to send it form client(mobile) to server then to another client2(mobile). I don't know how to write code in Java to send the playPackets continuously to server and receive the playPacket continuously from the server to the clients. I guess i have to use two thread one for sending and one for receiving. Can someone help me with the code, or the procedure to write code for it. Thanks in advance.

  • How can I use Spring Security without sessions?

    - by Jarrod
    I am building a web application with Spring Security that will live on Amazon EC2 and use Amazon's Elastic Load Balancers. Unfortunately, ELB does not support sticky sessions, so I need to ensure my application works properly without sessions. So far, I have setup RememberMeServices to assign a token via a cookie, and this works fine, but I want the cookie to expire with the browser session (e.g. when the browser closes). I have to imagine I'm not the first one to want to use Spring Security without sessions... any suggestions?

  • System.Security.Permissions.SecurityPermission and Reflection on Godaddy

    - by David Murdoch
    I have the following method: public static UserControl LoadControl(string UserControlPath, params object[] constructorParameters) { var p = new Page(); var ctl = p.LoadControl(UserControlPath) as UserControl; // Find the relevant constructor if (ctl != null) { ConstructorInfo constructor = ctl.GetType().BaseType.GetConstructor(constructorParameters.Select(constParam => constParam == null ? "".GetType() : constParam.GetType()).ToArray()); //And then call the relevant constructor if (constructor == null) { throw new MemberAccessException("The requested constructor was not found on : " + ctl.GetType().BaseType.ToString()); } constructor.Invoke(ctl, constructorParameters); } // Finally return the fully initialized UC return ctl; } Which when executed on a Godaddy shared host gives me System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

  • Traffic fall after a server problem

    - by Sébastien
    I have a website from which I analyse the traffic with Google analytics. Day after day the traffic (mainly from Google SE) incresed until I get a problem with my server. For one day the server has been offline and after that I have no longer had as much users as I had before. Now it's like the site is no more referenced on Google index (but when I type "site:mysite.com", I still have all the results). Do you know if this is a normal behaviour and if the traffic will come back as before (the server has had problems two days ago) ?

  • Group SQL tables in SQL Server Management Studio object explorer

    - by MainMa
    I have a table which has approximately sixty tables, and other tables are added constantly. Each table is a part of a schema. A such quantity of tables makes it difficult to use Microsoft SQL Server Management Studio 2008. For example, I must scroll up in object explorer to access database related functions, or scroll down each time I need to access Views or Security features. Is it possible to group several tables to be able to expand or collapse them in Object Explorer? Maybe a folder may be displayed for each schema, letting collapse the folders I don't need to use?

  • Looking for SQL Server Performance Monitor Tools

    - by the-locster
    I may be approaching this problem from the wrong angle but what I'm thinking of is some kind of performance monitor tool for SQl server that works in a similar way to code performance tools, e.g. I;d like to see an output of how many times each stored procedure was called, average executuion time and possibly various resource usage stats such as cache/index utilisation, resultign disk access and table scans, etc. As far as I can tell the performance monitor that comes with SQL Server just logs the various calls but doesn't report he variosu stats I'm looking for. Potentially I just need a tool to analyze the log output?

  • SQL Server version of MySQL's group_concat and escaped strings

    - by TheObserver
    I only have the Express versions of MS SQL Server 2008 and Visual Studio. Given that I can't create a SQL Server project and therefore CLR solutions are out of the question, I've attempted to use select col1, stuff( ( select ' ' + col2 from StrConcat t1 where t2.col1 = t1.col1 for xml path('') ),1,1,'') from StrConcat t2 group by col1 order by col1 to get a row concatenated col2. col2 is a varchar field with some control characters like & and \n. When it is concatenated with the above SQL, it appears to escape those control characters ie. & becomes & amp ; and \n becomes &#xOD, which is not what I want it to do. So, the question is, what black box magic is causing that to happen?

  • Want to Learn SQL Server 2012?

    - by andyleonard
    Or SSIS 2012? SSRS 2012? SSAS 2012? There’s no substitute for getting your hands on the product, in my opinion. I can hear you thinking, “But Andy, I can’t afford to purchase a copy of SQL Server 2012.” Are you sure? What if I told you that you can get a full-feature version of SQL Server 2012 Enterprise Edition for $50? Well, you cannot… it’s actually less than $50! SQL Server 2012 Developer Edition is available at Amazon on the day of this writing for $41.24USD. That’s about the price of eight...(read more)

  • User account design and security...

    - by espinet
    Before I begin, I am using Ruby on Rails and the Devise gem for user authentication. Hi, I was doing some research about account security and I found a blog post about the topic awhile ago but I can no longer find it again. I read something about when making a login system you should have 1 model for User, this contains a user's username, encrypted password, and email. You should also have a model for a user's Account. This contains everything else. A User has an Account. I don't know if I'm explaining this correctly since I haven't seen the blog post for several months and I lost my bookmark. Could someone explain how and why I should or shouldn't do this. My application deals with money so I need to cover my bases with security. Thanks.

  • Data-related security Implementation

    - by devdude
    Using Shiro we have a great security framework embedded in our enterprise application running on GF. You define users, roles, permissions and we can control at any fine-grain level if a user can access the application, a certain page or even click a specific button. Is there a recipe or pattern, that allows on top of that, to restrict a user from seeing certain data ? Sample: You have a customer table for 3 factories (part of one company). An admin user can see all customer records, but the user at the local factory must not see any customer data of other factories (for whatever reason). Te security feature should be part of the role definition. Thanks for any input and ideas

Say by joining to another table perhaps?

  • Unable to connect to iFolder server

    - by Sven
    I tried to install iFolder on Ubuntu 10.10 server 64 bit using this guide. Everything "worked" except: If I try to acccess the server with http://myurl/admin I get the error-message "Unable to connect to the iFolder server." Has anyone succeeded with this guide, or is there an iFolder specialist who could help me with the last steps? Update 1: I could connect to the /admin-Interface by not changin anything in the config-script. Changing the ServerName in anything else than localhost brings back the error. And changing username and/or password has no affect.

  • Session ID Rotation - does it enhance security?

    - by dound
    (I think) I understand why session IDs should be rotated when the user logs in - this is one important step to prevent session fixation. However, is there any advantage to randomly/periodically rotating session IDs? This seems to only provide a false sense of security in my opinion. Assuming session IDs are not vulnerable to brute-force guessing and you only transmit the session ID in a cookie (not as part of URLs), then an attacker will have to access your cookie (most likely by snooping on your traffic) to get your session ID. Thus if the attacker gets one session ID, they'll probably be able to sniff the rotated session ID too - and thus randomly rotating has not enhanced security.
