When it comes to SP I have limited experience but some. I currently am in a MySQL environment and need to create and update many SPs. I would like to purchase a good SP book but I'm not sure if it should be based on MySQL or MS SQL. Is there that much of a difference in a MySQL SP and a MS SQL SP?? Ideally I would like to purchase just one book. I'm thinking maybe going with the MS SQL/SP book and using it for the MySQL environment as well. I would appreciate any advise as to why I should get one or the other.
