Dealing with Large SQL Scripts

Kevin Chant has some advice when you have to deal with a giant SQL script:

If you have been given a script that is thousands of lines long from a developer, the first thing I would ask is if they can split it up.

I say this because a lot of developers who write long scripts tend to have come from various backgrounds. Hence, some of them are used to developing on other programming languages.

So, they do not always appreciate that SQL is a set-based language. In addition, they do not always appreciate SQL Server is optimised for set based queries.

Sometimes you can break these scripts down, though there are of course good ways and bad ways to do so.
