CREATE PROCEDURE is a SQL statement used to create a stored procedure in a database. A stored procedure is a set of SQL statements that are saved in the database and can be executed repeatedly without needing to rewrite the code.
Here is an example of how to create a simple stored procedure in MySQL:
```
CREATE PROCEDURE myProcedureName()
BEGIN
SELECT * FROM myTable;
END;
```
This stored procedure is named `myProcedureName` and it simply selects all the rows from a table named `myTable`. Once the stored procedure is created, it can be executed by calling its name:
```
CALL myProcedureName();
```
This will execute the code inside the stored procedure and return the result set to the caller. Stored procedures are useful for encapsulating complex logic in a database and making it easier to manage and maintain.
