MySQL Stored Procedure Call Methods

There are several ways to call a stored procedure in MySQL.

1. Invoke the stored procedure using the CALL statement: You can use the CALL statement to directly call a stored procedure, such as CALL procedure_name(arguments);
2. Call stored procedure by its name: directly use the stored procedure name in the SQL statement to call the stored procedure, for example: procedure_name(arguments);
3. By using the PREPARE statement and EXECUTE statement: you can dynamically generate the SQL statement for calling a stored procedure using the PREPARE statement and then execute that SQL statement using the EXECUTE statement.
4. Using the return value of a stored procedure: Use OUT parameters or the RETURN statement within the stored procedure to return results, then call the stored procedure in SQL or other stored procedures to retrieve the return value.

These are commonly used ways to invoke stored procedures, with the specific method depending on the definition of the stored procedure and the required operation.
