MySQL存儲過程INSERT問題

Question

適用以下情況：

CREATE TEMPORARY TABLE IF NOT EXISTS `smth_table` (
  `login` VARCHAR(20),
  `password` VARCHAR(20),
  `type` INT(11),
  `account_state` DECIMAL(12,4)
);

PREPARE Selection FROM
   "INSERT INTO `smth_table`
    (SELECT ta.`login`, ta.`password`, ta.`type`, ta.`account_state`
    FROM tableA ta
    INNER JOIN tableB tb ON tb.id_client = ta.id_client
    WHERE tb.id_lot = ? AND ta.`type` MOD 2 = 0
    AND ta.first_use = '0000-00-00 00:00:00'
    AND ta.account_state = 0
    LIMIT ?)";
SET @WHERE = var1;
SET @LIMIT = var2;
EXECUTE Selection USING @WHERE, @LIMIT;
DEALLOCATE PREPARE Selection;

DECLARE curs CURSOR FOR
  SELECT `password` FROM `smth_table`;

DECLARE CONTINUE HANDLER
FOR NOT FOUND SET v_finished = 1;


OPEN pin_curs;

get_pass: LOOP
  FETCH curs INTO pass;
  IF v_finished = 1 THEN
     LEAVE get_pass;
  END IF;

  UPDATE tableA ta INNER JOIN tableB tb
  ON tb.id_client = ta.id_client
  SET `type` = `type` | 1,
  `account_state` = `account_state` + 5
  WHERE tb.id_lot = var1
  AND `password` = pass;


END LOOP get_pass;

 CLOSE curs;

END

為什么在運行此存儲過程時，臨時表中的填充量是否超過限制？ 請記住，我通過過程中傳入的IN變量設置了LIMIT，順便說一句，它是10。 但是，當我運行該過程時，它將在臨時表中插入更多的100行，而我不明白為什么，當它僅應插入10行時。

解決了！

問題是我沒有在再次創建表時刪除表，因此一遍又一遍地插入相同的值。

DROP TABLE IF EXISTS `smth_table`; 

這是在創建它之前插入的，並且查詢運行順利:-)
