  • Disallowing Running the Stored Procedure in Parallel

    I wrote a stored procedure a while back; it manipulates the database of a legacy and proprietary application. Few assumptions were taken like the stored procedure will always get invoked by the job and job doesn't run in parallel. Few weeks back there was a requirement to let the user do that operation from the web on demand; which triggered the ...

    Sometime while implementing some date/time specific business logic; we need to do some processing on datetime data; e-g trimming away the time, knowing the start of month datetime value.

  • Knowing current SPROC name

    Instrumentation though usually a ''non-functional requirement''; but its considered to be critical especially in ''enterprise class application''. For this we usually need to know what is the current part of code being executing; against which we can log some info. Same applies to data-tier; thankfully TSQL has required functionaliy.

  • TSQL :: Comparing multiple fields

    Sometimes you want to select from one list the items that exist (or don’t exist) in the second row; and for the comparison you want to use multiple rows.

    Comparing Checksum is one of the straight forward techniques to know if two things are different or not, especially when you are comparing some vector quantities. SQL Server 2005’s TSQL has two new relevant functions in this regard, checksum() and checksum_agg() Consider a test table having some values. Using checksum() you can have a computed ...

  • Can we use stored procedures in View?

    Well I have not gone through all the options yet; but I was able to did something that solved the problem at hand. The database at hand was exposed only through stored procedures; but one developer wanted to have a view; being new to Perl on Unix; he hasn’t yet explored how to execute stored procedures. He asked me to setup few views for him ...

  • Passing Array To Stored Procedures

    There are some scenarios; where you want to pass array to stored procedure. In SQL 2000; it was not possible. Different work-around was presented; like passing values as string and then parsing them out; passing data as XML and then using MSXML OLE automation object in SQL Server (sp_OACreate/sp_OADestroy). Both have the pit falls; parsing ...

  • sysxlogins

    SQL Server 2000 had certain system tables; using them was not encouraged and neither were they documented publicly. However no one was stopping you to use it and people have used it to do different things.

    Using transactions in SQL Server is sometimes tricky. Here is today’s learned lesson. If you set xact_abort to on; you don’t need to rollback the transaction; it gets automatically rolled back in case of any error. One thing that can lead you to problems is; that transactions get rolled back when you close the connection. If you want to perform ...

  • SQL Server:: Corrupt sysdepends can create problem in DTS

    SQL Server internally keeps tracks of database objects and their inter-dependencies.

The information of the database objects and their inter-decencies are stored in two special ...
