mysql Stored procedure is supported by mysql5.0 or later. It is similar to IBM's DB2 implementation, as both are based on SQL:2003 standard. Merits(why)Stored procedure can run in all environments, since they are on the database server.It makes no difference what application environment is used.Stored procedure can reduce network traffic,because complex repetative tasks can be done on databas...
