初めてカーソルを作っています。

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$$

私がやっていること 1) temp_weekly からすべてのキーを読み取り、反復します 2) 特定のキーの jira_local テーブルからすべてのレコードを見つけ、それが検証、解決された回数などを数えます。

問題：これをコンパイルするとエラーが発生します

ERROR 1193: Unknown system variable 'done1'

また、このリンクを参照して、ループ内にストアド プロシージャを作成しました

更新:私の手順 を宣言した後done/done1、次のようになります

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;
       .
       .
       .

これは私に与えます

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

done1で行ったように宣言する必要がありますdone：

から

DECLARE done INT DEFAULT FALSE;

に

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