删除粉丝表中抓取错误的数据-微信公众平台开发

Jun 02, 2016 am 09:13 AM

由于将公众平台的粉丝数据进行对应的时候会存在openid和fakeid对应错的问题,所以需要及时清理数据库中抓取错误的数据,上边的sql中删除一个公众帐号中fakeid出现两次的数据,下次用户在进行互动的时候在进行抓取.

下面我给各位同学写了一条删除错误数据的sql希望对各位有帮助,代码如下:

SELECT *  
    FROM enet_wechatfans 
    WHERE fakeid 
    IN ( 
        SELECT fakeid 
        FROM ( 
            SELECT COUNT( * ) c, id, fakeid 
            FROM  `enet_wechatfans`  
            WHERE weid =135 
            GROUP BY fakeid 
            HAVING c >1 
        ) AS tmp 
    ) AND weid = 135 
    //开源代码phprm.com
