第 2 部分：使用产品和产品库存表创建存储过程。此存储过程应声明一个变量并将其设置为产品表中所有产品的计数。如果计数大于或等于 20，存储过程应显示一条消息“库存计数大于或等于 20”。否则，应显示“产品库存数量少于 20”。
CREATE PROCEDURE Moreorless20ProductInventory
AS
BEGIN
DECLARE @countprod INT
SELECT @countprod = countprod
FROM
(SELECT COUNT(*)
INTO countprod
FROM Production.ProductInventory);
IF @countprod >= 20
BEGIN
SELECT 'The number of products is greater than or equal to 20' as col1;
ELSE
SELECT 'The number of products is less than 20' as col1;
END IF;
END
