Обсуждение: Query generator
Hi everyone,
Does anyone know a random query generator for Postgres? Something that gets my schema and, based on that, generates hundreds of different queries with join, group by, etc.
Thank you.

You should try sqlsmith (https://github.com/anse1/sqlsmith), which works
very well.
I had found this one before, but all I could get was queries using "standard" tables, like the ones from pg_catalog and information_schema. It didn't generate queries from the tables I've created. Was I doing something wrong?

I never had this issue myself, so I can only advice you to open an issue on the project repository if you still have this problem. -- Julien Rouhaud http://dalibo.com - http://dalibo.org

You could verify this for with, e.g., sqlsmith --dry-run | grep your_table_name Thanks to Julien, sqlsmith's master branch now has an option --exclude-catalog that inhibits use of catalog relations. If you are building from github, you might want to give it another chance with this option. I'll probably do a proper release in next two weeks. Feedback welcome :-) regards, Andreas

Yes, I was talking in private with him and he came up with this solution. Thank you again, Julien.
I need to try it again, did a quick test on friday, but it looks like it works perfectly! :)
