Mysql ：根据某字段值作判断再来更新某字段的值

1、问题描述：

    今天更新某表时出现You can't specify target table '表名' for update in FROM clause这种错误，意即不能先select出同一表中的某些值，再update这个表(在同一语句中)，即不能依据某字段值作判断再来更新某字段的值。

2、解决方案：

     将SELECT出的结果再经过中间表SELECT一遍，具体可参考以下：

UPDATE `auto_picture_text_library` c -- 从图文库表中获取未使用的图文库id
SET c.`is_deleted` = 0,
c.`modify_time` = NOW( ) 
WHERE
	c.id IN (
	SELECT
		d.id 
	FROM
		(
		SELECT
			a.id 
		FROM
			auto_picture_text_library a
			LEFT JOIN auto_picture_text_library_page b ON a.id = b.library_id 
		WHERE
			a.id IN ( 1, 2, 3 ) 
			AND a.is_deleted = 0 
			AND a.company_id = 3 
			AND ( b.is_deleted = 1 OR b.page_id IS NULL ) 
		) d
	)
