Delete Orphan Records

I have a couple of tables, one with Sources and one with Articles. I link the articles back to sources with a Source ID column in the Articles table.

What I'm wondering is if theres a simple way to delete all Articles records where the Source record it has in the Source ID column does not exist in the Sources table.

It seems like I should be able to do this with a single SQL statement, but I haven't been about to find how to do it. Right now I'm doing crazy loops through thousands of records to check for matches and delete ones that don't match.

Any suggestions?

Try

DELETE FROM Articles WHERE SourceID NOT IN (SELECT SourceID FROM Sources)
