Often I find myself working on a new project with a giant RDBMS whose schema I don’t yet understand. I want to be able to mark a checkpoint in the database, do something in the app, and then go back to the database and ask it which tables changed (and ideally, what records changed).
Is there a way to do something like this with SQL? I found this, but it’s MSSQL-only (which I’m not using).
It doesn’t need to be super efficient. It’s just going to be on my dev box and I can wait a few seconds if need be, but I am looking for something better than ‘dump the whole DB twice and diff the results’.
If your DBMS supports query logging, turn it on and tail -f the log.
