mysql 使用 if 退出 sp

Question

在下面的 msql sp 中，如果星期几是星期五，我将尝试退出，但我无法让它工作，因为 "END IF;" 处存在语法错误，我只是看不到它.

    CREATE PROCEDURE `bookFreeDay`()
    proc_label:BEGIN

  DECLARE bDone INT;
  DECLARE t1 VARCHAR(5);

  -- todo exclude sa/so
  IF DAYOFWEEK(SUBDATE(CURDATE(),1)) = 5 THEN
      LEAVE proc_label;
  END IF;

  DECLARE curs CURSOR FOR select durTime from freeDays where
    (year is not null && year= substring(CURDATE(),1,4) && start=substring(SUBDATE(CURDATE(),1), 6,5))
    || (year is null && start=substring(SUBDATE(CURDATE(),1), 6,5));

  DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;

  OPEN curs;

  SET bDone = 0;
  REPEAT
    FETCH curs INTO t1;

        select CONCAT(SUBDATE(CURDATE(),1), " 08:00:00") into @st;
        select addtime(@st, t1) into @en;

       insert into timeEntries
         (select
           null,
           idUsers,
           @st,
           @en,
           null,
           2
         from users
         where right(pensum,1)='%');

  UNTIL bDone END REPEAT;

  CLOSE curs;

END

14.6.6.2 Cursor DECLARE Syntax

...

Cursor declarations must appear before handler declarations and after variable and condition declarations.

...

/*
-- todo exclude sa/so
IF DAYOFWEEK(SUBDATE(CURDATE(),1)) = 5 THEN
  LEAVE proc_label;
END IF;
*/

DECLARE curs CURSOR FOR select durTime
                        from freeDays
                        where (year is not null &&
                               year= substring(CURDATE(),1,4) &&
                               start=substring(SUBDATE(CURDATE(),1), 6,5)) ||
                              (year is null &&
                               start=substring(SUBDATE(CURDATE(),1), 6,5));

DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;

-- todo exclude sa/so
IF DAYOFWEEK(SUBDATE(CURDATE(),1)) = 5 THEN
  LEAVE proc_label;
END IF;
