Stored Procedures

Important Points

  • A Stored Procedure is a set of SQL commands. Each Stored Procedure has a unique name, and it acts like a function. Therefore, it can be called or executed like a function;

  • Stored Procedures can be created using the CREATE PROCEDURE statement;

  • Stored Procedures can be executed using the CALL statement;

  • We can use the ExecuteReader or ExecuteNonQuery methods of the MySqlCommand object for calling a Stored Procedure;

  • If the Stored Procedure has an OUT parameter (a parameter which has an out keyword before it), we need to manually specify the values for its arguments using the AddWithValue and Add methods of the MySqlCommand's Parameter attribute;

  • The direction of an out parameter of a Stored Procedure must be set to ParameterDirection.Output before executing the Stored Procedure.
