Execution of Code on Multiple Servers Remotely

Do you have more than 10 sql servers you must manage? Most DBA s do, I have over 120 sql instances to manage. Before I used to use ISQL/OSQL in a batch to execute a command on all these instances. It works but not very nice. Below is the code I use to collect information […]

faster dbo.ufn_vbintohexstr - varbinary to hex

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 […]

HexToInt

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 […]
