A client wants a database converting from MS SQL to MySql.
Personally I wouldn't do this, I prefer MS SQL for larger databases and like the tools available when working with MSSQL.
However I do use MySql on smaller projects. I've never moved a database from one to the other, or made much use of sprocs when using mysql.
Is there a lot of work involved in rewriting the sprocs, considering I have no prior knowledge of the ms sql database itself, so will need to first gain an understanding of what each sproc does.
This isn't a discussion on which to use as that's already been decided by the client for a few reasons.
