Thanks for the quick and flame free reply Erland. I did fail to
mention the version of SQL I am using: SQL 2005.
I found in Query > Query Options > Execution > General > Execution
Time Out (currently set to 0 seconds).
I'm guessing that if I set this to 600, my query would terminate at 10
minutes if it didn't complete?
