第一个:

DELETE
			a
			FROM
				[dbo].[PAT_FOLLOW_UP] AS a
				LEFT JOIN [dbo].[PAT_FOLLOW_UP_TREAT] AS b ON a.FU_TIMES= b.FU_TIMES
				LEFT JOIN [dbo].[PAT_FOLLOW_UP_RESULT] AS c ON a.FU_TIMES= c.FU_TIMES
			WHERE
				a.FOLLOW_UP_DATE = ''
				AND a.FU_REASON = ''`

我想删除三个表中根据 WHERE 条件中查询到的数据,但是报了 语法 错误。那位大佬知道应该怎么改吗?

第二个:

我想查询所有 FOLLOW_UP_DATE 为空的数据,以验证上边删除是否成功了。但是报了 数据类型 错误,请问 access 中的时间格式应该怎么写?

我上面的代码在 SQL server 中是可以运行成功的。但是 access的语法好像和 SQL server 中的不太一样,有没有什么学 access 语法的教程可以推荐下?
