SQL2000 only.We use the attached script to schedule a SQL Agent job that sets up a Profile trace looking for long queries, and hourly imports them into a table. This way we can historically (but with some degree of real time) look to see what queries put a load on the system. We then allow […]

This a script to compare two parallel data streams, in my case production and QA. Two extracts were created and a mapping table was created as a look-up between old and new recordids.

SQL 2000's sp_MSForEachDB and sp_MSForEachTable are useful procedures for performing operations against multiple objects; however, they aren't always extremely efficient, because internally they use cursors to do their work.These 2 sprocs, sp_ForEachDB and sp_ForEachTable, perform many of the same tasks as their Microsoft-shipped twins, but run faster because they dynamically build the SQL string without […]
