MySQL的遊標錯誤1193：未知的系統變量

Question

我創建的第一次光標（指this site） 我做了這個至今（

CREATE PROCEDURE `abc`.`cursordemo` (IN start_date DATETIME,IN end_date DATETIME) 
BEGIN 
DECLARE done INT DEFAULT FALSE; 
    DECLARE k1,k2,g,s,last_status VARCHAR(45); 
    DECLARE b, c INT; 
    DECLARE cur1 CURSOR FOR SELECT `key` FROM `abc`.`temp_weekly`; 
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE; 

OPEN cur1; 
read_loop: LOOP 
    FETCH cur1 INTO k1; 
    IF done THEN 
     LEAVE read_loop; 
    END IF; 
    block_cursor:BEGIN 
     DECLARE cur2 CURSOR FOR SELECT `key`,`group`,`status` FROM `abc`.`jira_local` WHERE `key` = k1 AND updateddate < end_date; 
     DECLARE CONTINUE HANDLER FOR NOT FOUND SET done1 = TRUE; 
     OPEN cur2; 
     REPEAT 
      FETCH cur2 INTO k2,g,s; 
      IF NOT done1 THEN 


      IF s != last_status THEN 
       CASE 
        WHEN s = 'verified' THEN 
        SET c = c +1; 
        WHEN s = 'closed' THEN 
        SET c = c +1; 
        WHEN s = 'to be scheduled' THEN 
        SET c = c +1; 
        WHEN s = 'deferred' THEN 
        SET c = c +1; 
/*'resolved','closed','to be scheduled','deferred','validated','assigned','l3 need more info','l2 need more info','need more info'*/ 
        WHEN s = 'resolved' THEN 
        SET c = c +1; 
        WHEN s = 'validated' THEN 
        SET c = c +1; 
        WHEN s = 'assigned' THEN 
        SET c = c +1; 
        WHEN s = 'l3 need more info' THEN 
        SET c = c +1; 
        WHEN s = 'l2 need more info' THEN 
        SET c = c +1; 
        WHEN s = 'need more info' THEN 
        SET c = c +1; 
       END CASE; 
       SET last_status = s; 
      END IF; 
      END IF; 
     UNTIL NOT done1 END REPEAT; 
     INSERT INTO ticketsResolvedCount values(k2,g,s,c); 
    END block_cursor; 

    END LOOP; 

    CLOSE cur1; 
    CLOSE cur2; 
END$$ 

我在做什麼 1）讀取所有的鍵temp_weekly和迭代 2）找到jira_local表中的所有記錄一個特定的鍵和計數的時候，它被驗證的數量，解決等

問題： 當我編譯這個它給出了一個錯誤

ERROR 1193: Unknown system variable 'done1' 

而且，我提到this鏈接，創建一個循環內的存儲過程

UPDATE： 聲明done/done1後，我的過程是這樣的

BEGIN 

     DECLARE k1,k2,g,s,last_status VARCHAR(45); 
     DECLARE b, c INT; 
     DECLARE cur1 CURSOR FOR SELECT `key` FROM `abc`.`temp_weekly`; 
     DECLARE done1 BOOLEAN DEFAULT FALSE; 
     DECLARE done BOOLEAN DEFAULT FALSE; 
     DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE; 
     . 
     . 
     . 
block_cursor:BEGIN 
     DECLARE cur2 CURSOR FOR SELECT `key`,`group`,`status` FROM `abc`.`jira_local` WHERE `key` = k1 AND updateddate < end_date; 
     DECLARE CONTINUE HANDLER FOR NOT FOUND SET done1 = TRUE; 
     . 
     . 
     . 

這給了我

ERROR 1337: Variable or condition declaration after cursor or handler declaration 

Answer 1

您需要申報done1爲您done做：

從

DECLARE done INT DEFAULT FALSE; 

到

DECLARE done, done1 INT DEFAULT FALSE; 
      ^^^^^^^
