Using Git to track mysql schema - some questions

Question

If this is recommended ?

Can I ask some git command examples about how to track versions of mysql schema?

Should we use another repository other then the on

Answer 1

The following includes a git pre-commit hook to capture mysql database/schema, given user='myuser', password='mypassword', database_name='dbase1'. Properly bubbles errors up to the git system (the exit 0's in other answers could be dangerous and may not handle error scenarios properly). Optionally, can add a database import to a post-checkout hook (when capturing all the data, not just schema), but take care given your database size. Details in bash-script comments below.

pre-commit hook:

#!/bin/bash

# exit upon error
set -e
# another way to set "exit upon error", for readability
set -o errexit

mysqldump -umyuser -pmypassword dbase1 --no-data=true > dbase1.sql

# Uncomment following line to dump all data with schema,
# useful when used in tandem for the post-checkout hook below.
# WARNING: can greatly expand your git repo when employing for
# large databases, so carefully evaluate before employing this method.
# mysqldump -umyuser -pmypassword dbase1 > dbase1.sql

git add dbase1.sql

(optional) post-checkout hook:

#!/bin/bash
# mysqldump (above) is presumably run without '--no-data=true' parameter.
set -e
mysql -umyuser -pmypassword dbase1 < dbase1.sql
