Stored routines (procedures and functions) are supported in MySQL 5.0. A stored procedure is a set of SQL statements that can be stored in the server. Once this has been done, clients don't need to keep reissuing the individual statements but can refer to the stored procedure instead.
Write actions out in the order in which they happen. Avoid too many words. Use the active voice. Use lists and bullets. Don't be too brief, or you may give up clarity. Explain your assumptions, and make sure your assumptions are valid. Use jargon and slang carefully.

What are stored procedures and functions?
Stored Procedure: This is a pre-compiled object as this gets compiled for the first time and its compiled format gets saved as well, which gets executed (compiled code) when it is called.
