Why it is called stored procedure?
A stored procedure is a set of instructions for a database, like a function in EGL. Stored procedures differ from prepared statements because the stored procedure is kept permanently in the database itself, while a prepared statement is local to your program or logic part and is cached by the database only temporarily.
