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

I have found the following options to be mandatory for a version control / git-compatible mysqldump.

mysqldump --skip-opt --skip-comments |sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/'

(and maybe --no-data)

--skip-opt is very useful, it takes away all of --add-drop-table --add-locks --create-options --disable-keys --extended-insert --lock-tables --quick --set-charset. The DEFINER sed is necessary when the database contains triggers.

While I am not using Git, I have used source control for over 15 years. A best practice to adhere to when deciding where and how to store your src and accompanying resources in Source Control: If the DB Schema is used within the project then you should be versioning the schema and all other project resources in "that" project. If you develop a set of schemas or programming resources that you resuse in other projects then you should have a seperate repository for those reusable resources. That seperate Reusable resources project will be versioned on it's own and will track the versions of the actual reusable resources in that repository.

If you use a versioned resource out of the reusable repository in a different project then you have the following scenario, (just an example). Project XYZ version 1.0 is now using DB Schema_ABC version 4.0 In this case you will understand that you have used a specific version of a reusable resource and since it is versioned you will be able to track its use throughout your project. If you get a bug report on DBSchema_ABC, you will be able to fix the schema and re-version as well as understand where else DBSchem_ABC is used and where you may have to make some changes. From there you will also understand which projects contain wich versions of which reusable resources... You just have to understand how to track your resources.

Adopting this type of development Environment and Resource Management strategy is key to releasing usable software and managing a break/fix enhancement environment. Even if you're developing for your own edificcation on your own time, you should be using source control.. as you are..

As for Git, I would find a gui front end or a dev env integration if I can. Git is pretty big so I am sure it has plenty of front end support, maybe?
