TAILIEUCHUNG - SQL Server Tacklebox- P29

SQL Server Tacklebox- P29: This book, as with almost all books, started out as an idea. I wanted to accumulate together those scripts and tools that I have built over the years so that DBAs could sort through them and perhaps adapt them for their own circumstances. | 5 DBA as detective .

You might decide that you would like to take this query and make it into a stored procedure. You can then load it into a maintenance database on each server so that you have it always available. It also means that you can parameterize it to control its behavior. For example you may decide that you do not want to execute the portion of the query that counts locks which on a very busy system could take quite a bit of time. Listing shows the code to create this stored procedure named usp_Find_Problems with a flag to execute the lock count portion based on need.
