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'

去掉所有的prepared statements，使用固定的表名，行得通，所以问题出在prepared statement stmt3。

如果我更改开始日期，我会得到相同的错误但具有不同的值。

最佳答案

问题是您在创建的查询字符串中没有将 full_date 引号括起来。所以，你会得到类似的东西:

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,
        . . . 

您的版本进行算术计算 (1900 - 04 - 01 = 1895)，因此它变成:

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

顺便说一下，如果您查看变量替换后的字符串，我猜这会很明显。无论何时使用动态 SQL，您都应该始终查看生成的查询字符串。

您可以通过在整个语句中放置单引号分隔来解决此问题。或者，更好的是，将语句参数化并使用 EXECUTE 。 . .使用(参见 here )。

编辑:

您可以将查询写成以下形式:

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。
