我的存儲過程的返回值

Question

我使用存儲過程來優化我的sql腳本的查詢。這是一個腳本來更新我的數據庫時，我執行它的表我沒有錯誤在同一時間，我沒有結果。我怎樣才能返回我的存儲過程的值？

這裏是我的腳本：

Answer 1

可以使用OUT參數的過程。

DELIMITER $$ 
CREATE PROCEDURE CountOrderByStatus(
IN orderStatus VARCHAR(25), 
OUT total INT) 
BEGIN 
SELECT count(orderNumber) 
INTO total 
FROM orders 
WHERE status = orderStatus; 
END$$ 
DELIMITER ; 

調用過程

CALL CountOrderByStatus('Shipped',@total); 
SELECT @total;
