Question

我正在尝试从3个表中更新一个表工作正常，但我想在第4个表中插入数据之后从3更新表，这里我正在做什么

INSERT INTO relation_table(cid,pid,liid,lnid,lgid,l_key)
SELECT  a.cid,
        a.pid,
                b.liid,
                c.lnid,
                d.lgid,
                md5(CONCAT(a.cid, a.pid, a.lurl, c.lnid, d.lang))
FROM    links a
        INNER JOIN links_table b
            ON a.lurl = b.lurl
        INNER JOIN lname_table c
            ON a.lname = c.lname
                INNER JOIN lang_table d
            ON a.lang = d.lang
where a.checked != "3" limit 2;

update links SET checked='3'
WHERE lid=a.lid

最后声明不适用于更新

请帮助;）
