Thanks for that.   We use synonyms to refer to other databases so hopefully that shouldn't cause too many issues.

I'll give it a go with a test database and...

If you've got this all inside a VS database project, editing the .sql files for the tables and then Publishing does everything for you.

(for Phil - OP has DROP_EXISTING = ON so indexes are there already while...

Are you saying that this proc runs slower in SSIS than it would if you were running it from SSMS?
