当我尝试使用 IF 语句时 mySql 查询错误

Question

我无法在 MySQL 查询中找到错误。

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 10

当我删除时:

IF DAYOFWEEK(curdate()) BETWEEN 2 AND 6 THEN
END IF;

然后查询就可以正常执行。

我尝试在 IF 语句中使用制表符/空格

CREATE EVENT UPLOADTASK
ON SCHEDULE EVERY '1' DAY
STARTS '2019-07-09 00:00:00'
DO
IF DAYOFWEEK(curdate()) BETWEEN 2 AND 6 THEN
  INSERT INTO TABLE1 VALUES
  (1,"TASK1",curdate()-1,NULL),
  (6.5,"TASK2",curdate()-1,NULL),
  (3.0,"TASK3",curdate()-1,NULL),
  (8,"TASK44",curdate()-1,NULL);
END IF;

Answer 1

将 If 包含在 Begin End block 中

CREATE EVENT UPLOADTASK
ON SCHEDULE EVERY '1' DAY
STARTS '2019-07-09 00:00:00'
DO
 BEGIN
    IF DAYOFWEEK(curdate()) BETWEEN 2 AND 6 THEN
      INSERT INTO TABLE1 VALUES
      (1,"TASK1",curdate()-1,NULL),
      (6.5,"TASK2",curdate()-1,NULL),
      (3.0,"TASK3",curdate()-1,NULL),
      (8,"TASK44",curdate()-1,NULL);
    END IF;
 END
