Ask HN: What tooling do you use for SQL/DB migrations
My team is growing and maturing, and we want to start keeping migrations and changes to the DB structure in a deployable manner. What tooling have you found that works best for this need?

We write the migrations in SQL, committed as part of the pull request. Migrations tested on copies of production database along with the code changes. Automatically applied by a script when a pull request gets merged/deployed. No special tooling really, just a couple of SQL files.
We have a SQL preprocessor that lets us refer to environment globals and class constants in SQL, so we're not hard-coding magic numbers and strings in the SQL. It resolves those with reflection on the code and replaces the named globals/constants before sending the SQL to the database.
since we use django, its own migration works best.
