將存儲過程的結果插入現有表

Question

我有一個名爲Percentages with a Column的表稱爲5StarResults，我想用存儲過程名稱5star的結果填充此表。

當我使用'Call 5star'時，它只返回一個百分比，我想把這個百分比插入Percentages表中。

請你幫忙，我試圖編輯程序來包含一個Insert，但它總是返回說0行插入。

謝謝

編輯，

存儲過程如下

BEGIN 
    declare Rating5Total int default 5; 
    declare Rating5Win int default 5; 
    declare 5StarPerformance decimal; 
    set Rating5Total = (select COUNT(Ratings) from vHighPerformance where Ratings = 7); 
    set Rating5Win = (select COUNT(Results) from vHighPerformance where Ratings = 7 and Results = 1); 
    set 5StarPerformance = Rating5Win*100.0/Rating5Total; 
    Select 5StarPerformance; 
END 

Answer 1

如果某個選項是做在同一個存儲過程的INSERT，下面的代碼應該工作：

CREATE PROCEDURE `5star`() 
BEGIN 
    DECLARE Rating5Total INT DEFAULT 5; 
    DECLARE Rating5Win INT DEFAULT 5; 
    DECLARE 5StarPerformance DECIMAL(18, 3); 
    SET Rating5Total := (SELECT COUNT(Ratings) FROM vHighPerformance WHERE Ratings = 7); 
    SET Rating5Win := (SELECT COUNT(Results) FROM vHighPerformance WHERE Ratings = 7 AND Results = 1); 
    SET 5StarPerformance := Rating5Win*100.0/Rating5Total; 
    /* INSERT INTO percentages (percentage) VALUES (5StarPerformance); */ 
    INSERT INTO percentages (id, percentage) VALUES (1, 5StarPerformance) 
     ON DUPLICATE KEY UPDATE percentage = 5StarPerformance; 
    SELECT 5StarPerformance; 
END$$ 

一個例子可以在SQL Fiddle中看到。

UPDATE

如果您需要在表percentages一個單一的記錄，你可以做一個UPSERT。查看更新的代碼。
