Writing script creates and calls a stored procedure

Question

Write a script that creates and calls a stored procedure named test. This stored procedure should declare a variable and set it to the count of all products in the Products table. If the count is greater than or equal to 7, the stored procedure should display a message that says, “The number of products is greater than or equal to 7”. Otherwise, it should say, “The number of products is less than 7”.

DROP PROCEDURE IF EXISTS test;
CREATE  procedure test()
BEGIN
DECLARE count_of_7 DECIMAL(10,2);

SELECT  count(product_id) 
into count_of_7

FROM products;
IF count_of_7 >= 7 THEN

SELECT 'The number of products is greater than or equal to 7' AS message;
ELSE

SELECT 'The number of products is less than 7' AS message;
end if;
call test();

21:38:55 CREATE procedure test() BEGIN DECLARE count_of_7 DECIMAL(10,2) Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3 0.016 sec

Answer 1

You need to change the delimiter before declaring your procedure. Also, you are missing an END statement. This should work:

DROP PROCEDURE IF EXISTS test;
DELIMITER //
CREATE  procedure test()
BEGIN
    DECLARE count_of_7 DECIMAL(10,2);

    SELECT count(product_id) into count_of_7 FROM products;
    IF count_of_7 >= 7 THEN
        SELECT 'The number of products is greater than or equal to 7' AS message;
    ELSE
        SELECT 'The number of products is less than 7' AS message;
    END IF;
END //
DELIMITER ;
call test();
