Question

I am using SQL Server 2008 and I would like to know if there’s a way to find invalid SQL queries that have been executed in a database. For example:

SELECT * FROM NonExistingTable

…where the database didn’t exist or a SELECT/INSERT/UPDATE with incorrect syntax.

Answer 1

SQL Server doesn’t keep a log of these things, so if you want to capture them you’ll have to do so using a server-side trace with a filter to only capture statements with errors. It will be quite an expensive trace, and you’ll get some false positives if you do things like RAISERROR WITH NOWAIT… I guess it’s easier than implementing TRY/CATCH everywhere and logging the errors yourself?

There may be ways to do it with SQL Server Audit (depending on your edition)
or Extended Events but I haven’t tried to do this specific thing with either…
