Most of the time even after executing dbcc dbreindex script on database you won't see much improvement in application/DB performance. Thats because dbreindex creates statistics for all tables but it executes sp_updatestats which is like sample statistics. To get the maximum performance we had to execute Update statistics with fullscan on table. This simple will […]

Here's an alternative to Clinton Herring's ufn_vbintohexstr which should be much faster with large varbinary values. First, in his original version, the inner-loop CASE statements can be replaced with this: select @value = @value + CHAR(@vbin/16+48+(@vbin+96)/256*7) +CHAR(@vbin&15+48+((@vbin&15)+6)/16*7) How does it work? By adding 6 to a hex-digit in (@vbin&15), you have a value from 16 […]

This is just an optimized version of Daniel Payne's two scripts, base64_encode and base64_decode, with changes to end-of-block handling and a bug fix or two. If the encoded string ends in =, the last character is truncated. If ending in ==, two characters are chopped off. That seems better than replacing NUL characters with spaces, […]

Challenged by Hans Lindgren's stored procedures of the same name, I created this. Note that it produces strange results on non-hexadecimal strings, overflows at 0x80000000, and could have issues with byte-ordering on some architectures.How does it work? Well, the distance between one after '9' (':') and 'A' is 7 in ASCII. Also, if I subtract […]

SQLStackEngine - simulate a character stack using a string. This script was developed specifically to support the operator stack in SQLCalcEngine(also on this site). However, the implementation is complete enough to stand on its own.There are several functions in the package that correspond to the common stack functions of Push, Pop, Peek, and so on.In […]

Sometimes you want to modify an object (like a stored procedure, Function, trigger and view) and you can not remember the name of that object, but you remember some words of the comments that you placed in the body of that object. If this is your case, you can use the following procedures depending on […]

Drops the specified column from the specified table as well as any constraints that depend on the column. By default the script will just find the corresponding column and constraints.Comes in handy for patching databases.
