MySQL DECLARE/SELECT INTO語法錯誤？

Question

我真的不知道我在這裏做錯了什麼。

Routine Name: procInsertName 
Type: PROCEDURE 
Parameters: IN Name VARCHAR 30 Charset 

DECLARE tempNameID INT; 

SELECT nameID 
INTO tempNameID 
FROM name 
WHERE value = @Name; 

IF tempNameID IS NULL THEN 

    INSERT INTO name (value) 
    VALUES (@Name); 

END IF; 

Is deterministic: unchecked 
Definer: <blank> 
Security type: DEFINER 
SQL data access: CONTAINS SQL 
Comment: <blank> 

我走出來的一個錯誤：

One or more errors have occurred while processing your request: 

The following query has failed: "CREATE PROCEDURE `procInsertName`(IN `Name` VARCHAR(30)) NOT DETERMINISTIC CONTAINS SQL SQL SECURITY DEFINER DECLARE tempNameID INT; 

SELECT nameID 
INTO tempNameID 
FROM name 
WHERE value = @Name; 

IF tempNameID IS NULL THEN 

    INSERT INTO name (value) 
    VALUES (@Name); 

END IF;" 

MySQL said: #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 'DECLARE tempNameID INT; 

SELECT nameID 
INTO tempNameID 
FROM name 
WHERE valu' at line 1 

任何幫助，將不勝感激，我已經花了近30分鐘線上看四周，找不到任何東西。謝謝。

我認爲錯誤可能在於@符號...您必須來自SQL Server後臺; MySQL不使用變量@表示法，因此您的參數實際上只稱爲Name。嘗試將您的Name參數重命名爲p_Name，然後在存儲過程的主體中將@Name的兩個實例替換爲p_Name。

I.e.像這樣：

CREATE PROCEDURE `procInsertName`(IN `p_Name` VARCHAR(30)) NOT DETERMINISTIC CONTAINS SQL SQL SECURITY DEFINER 
DECLARE tempNameID INT; 

SELECT nameID 
INTO tempNameID 
FROM name 
WHERE value = p_Name; 

IF tempNameID IS NULL THEN 

    INSERT INTO name (value) 
    VALUES (p_Name); 

END IF;
