A stored procedure is a compiled, optimized set of SQL statements placed on the database server, which can be called directly by the application. There are several advantages to using stored procedures:1. Faster execution speed than normal SQL statements2, easy to centralized control3, can reduce the network traffic4, ensure the security and integrity of the data

procedures with parameters, you can only use the command object to call (it can also be called through the connection object or recordset object, but I have not tried it ). 4. Stored Procedures with Input and Output Parameters The returned value is actually a special output parameter. In most cases, we use a stored procedure with both input and output parameters
