MySQL：從函數調用存儲過程

Question

我在MySQL String_Split中存儲了過程。

DROP PROCEDURE IF EXISTS String_Split; 
DELIMITER $$ 
CREATE PROCEDURE String_Split(vString VARCHAR(8000),vSeparator VARCHAR(5)) 
BEGIN 

DECLARE vDone tinyint(1) DEFAULT 1; 
DECLARE vIndex INT DEFAULT 1; 
DECLARE vSubString VARCHAR(500); 

DROP TEMPORARY TABLE IF EXISTS tmpIDList; 
CREATE TEMPORARY TABLE IF NOT EXISTS tmpIDList (ID varchar(500)); 

WHILE vDone > 0 DO 
    SET vSubString = SUBSTRING(vString, vIndex, 
        IF(LOCATE(vSeparator, vString, vIndex) > 0, 
         LOCATE(vSeparator, vString, vIndex) - vIndex, 
         LENGTH(vString) 
        )); 
    IF LENGTH(vSubString) > 0 THEN 
     SET vIndex = vIndex + LENGTH(vSubString) + 1; 
     INSERT INTO tmpIDList VALUES (vSubString); 
    ELSE 
     SET vDone = 0; 
    END IF; 
END WHILE; 

END$$ 
DELIMITER ; 

我從函數調用這個存儲過程。

DROP FUNCTION IF EXISTS test; 
DELIMITER $$ 
    CREATE FUNCTION test (IDLIST VARCHAR(255)) 
    RETURNS VARCHAR(2000) 
    BEGIN 
     DECLARE returnData VARCHAR(2000); 

     DROP TEMPORARY TABLE IF EXISTS TEMP1;  
     CREATE TEMPORARY TABLE IF NOT EXISTS TEMP1(id bigint); 

     CALL String_Split(IDLIST,','); 
     INSERT INTO TEMP1 (SELECT * FROM tmpIDList); 

     SELECT GROUP_CONCAT(first_name) INTO returnData 
     FROM user_master 
     WHERE id IN (SELECT id FROM TEMP1); 

     RETURN returnData; 
    End $$ 
DELIMITER ; 

但我發現了以下異常

Error Code: 1146. Table 'backup25dec_latest.tmpidlist' doesn't exist 

Answer 1

我無法重現該問題。

確實生成了兩個警告（NOTE），但該行爲記錄在13.1.28 DROP TABLE Syntax中。
