Mysql错误：1292显示日期不存在的日期时间值不正确

我在此存储过程中遇到了错误：

    EXECUTE stmt3;

    SET full_date = DATE_ADD(full_date, INTERVAL 1 DAY);
END WHILE;
END

如果我执行：

CALL populateTimeTable('dim_time','1900-04-01','1901-01-01')

我得到：

Error Code: 1292 Incorrect datetime value: '1895'

删除所有准备好的语句并使用固定的表名即可,因此问题出在准备好的语句stmt3上.

如果更改开始日期,则会出现相同的错误,但值不同.

解决方法:

问题是您在创建的查询字符串中在full_date前后没有引号.因此,您得到的是：

VALUES ( 
        DATE_FORMAT( 1900-04-01, "%Y%m%d"),'
        1900-04-01,
        . . . 

这不同于：

VALUES ( 
        DATE_FORMAT('1900-04-01', "%Y%m%d"),'
        1900-04-01,
        . . . 

您的版本执行算术计算(1900-04-01 = 1895),因此变成：

VALUES ( 
        DATE_FORMAT( 1895, "%Y%m%d"),'
        1895,
        . . . 

顺便说一句,我猜测如果您在变量替换后查看字符串,这将是显而易见的.每当使用动态SQL时,都应该始终查看正在生成的查询字符串.

您可以通过在整个语句中使用单引号分隔来解决此问题.或者,更好的是,对语句进行参数化并使用EXECUTE. . .使用(请参阅here).

编辑：

您可以使用以下形式编写查询：

insert into table_name(. . . )
    select DATE_FORMAT(full_date, '%Y%m%d), 
           full_date,
           YEAR(full_date),
           . . .
    from (select ? as full_date, . . .) t;

每个参数都在子查询中.然后可以在外部查询中使用这些值.
