Logging Messages with Raiserror – #SQLNewBlogger

Another post for me that is simple and hopefully serves as an example for people trying to get blogging as #SQLNewBloggers.

I recently ran across some people discussing how to log some information in a script. One person was using PRINT, which I often use for quick checks, but someone else noted the RAISERROR works well, and you can customize messages.

For example, I can have this type of script:


-- do stuff

RAISERROR('%s - something happened at this time', 0, 1, @d)

This allows me to add information into an error message. I can certainly construct @d with other stuff and then use that in PRINT, but I could get out of order messages. If  I add NOWAIT, I can ensure my messages get returned immediately.

There are lots of options with RAISERROR, which I still use in place of THROW at times. While I like THROW, I think it doesn’t always give me the options I want for error handling, such as logging to the Windows lots.

When I saw this, I realized that I didn’t know, or remember, some of the ins and outs of RAISERROR, so I spent a few minutes looking through docs and playing with the code. I then wrote this quick post to help me remember a bit more.

Short and quick is a good way to structure posts. I didn’t walk about all the options or ways I can use things. I’ll do some of that in another post.
