Mysql錯誤1064 while Insert

Question

我是MySql的新手。我創建了一個程序：

DELIMITER $$ 

CREATE PROCEDURE `sampledb`.`InsertSample` 
(
    IN aName VARCHAR(20), 
    IN aVersion VARCHAR(10), 
    IN pName VARCHAR(50), 
    OUT InsertStatus VARCHAR(30) 
) 
BEGIN 
IF NOT EXISTS(SELECT st.AName FROM sampletable st WHERE st.AName = aName) 
    INSERT INTO sampletable(AName, AVersion, PName) 
    VALUES(aName, aVersion, pName) 
    SET InsertStatus = 'Success' 
ELSE 
    SET InsertStatus = 'Already exists!' 
END IF 
END$$ 

DELIMITER $$; 

我試過其他方式插入太深：

INSERT INTO sampletable (aName, aVersion, pName) 

無論是時間，我得到這個錯誤：

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 .. 

我使用MySQL 5.0。 51b-community-nt

Answer 1

您的代碼缺少分號（;）。

變化

BEGIN 
IF NOT EXISTS(SELECT st.AName FROM sampletable st WHERE st.AName = aName) THEN 
    INSERT INTO sampletable(AName, AVersion, PName) 
    VALUES(aName, aVersion, pName) 
    SET InsertStatus = 'Success' 
ELSE 
    SET InsertStatus = 'Already exists!' 
END IF 
END$$ 

DELIMITER $$; 

TO

BEGIN 
IF NOT EXISTS(SELECT st.AName FROM sampletable st WHERE st.AName = aName) THEN 
    INSERT INTO sampletable(AName, AVersion, PName) 
    VALUES(aName, aVersion, pName); 
    SET InsertStatus = 'Success'; 
ELSE 
    SET InsertStatus = 'Already exists!'; 
END IF; 
END; 
$$ 

DELIMITER ; 

，它應該是工作。

Answer 2

試試這個：

DELIMITER $$ 

CREATE PROCEDURE `sampledb`.`InsertSample` 
(
    IN aName VARCHAR(20), 
    IN aVersion VARCHAR(10), 
    IN pName VARCHAR(50), 
    OUT InsertStatus VARCHAR(30) 
) 
BEGIN 

IF NOT EXISTS(SELECT st.AName FROM sampletable st WHERE st.AName = aName) THEN 
    INSERT INTO sampletable(AName, AVersion, PName) VALUES(aName, aVersion, pName); 
    SET InsertStatus = 'Success'; 
ELSE SET InsertStatus = 'Already exists!'; 

END IF; 

END$$ 

DELIMITER $$; 

你需要確保你標記每行的結束，你在發言中缺少一個THEN子句
