CREATE OR REPLACE PROCEDURE is a SQL statement used to create or modify a stored procedure in a database.
The syntax for creating a stored procedure using CREATE OR REPLACE PROCEDURE is as follows:
```
CREATE OR REPLACE PROCEDURE procedure_name
(parameter1 datatype, parameter2 datatype, …)
AS
BEGIN
-- SQL statements
END;
```
The procedure_name is the name of the stored procedure that you want to create or modify. The parameters are optional and represent the input parameters for the procedure. The SQL statements within the BEGIN and END blocks define the logic of the stored procedure.
If a stored procedure with the same name already exists, using CREATE OR REPLACE PROCEDURE will replace the existing procedure with the new definition. This can be useful when modifying an existing stored procedure without having to drop and recreate it.
Once the stored procedure has been created or modified, it can be executed using the EXECUTE statement.
