整理QQ数据库sql语句

设置数据库的时候 qq 号如果用整型,设置成UNSIGNED,不然超过一定数值就错误

UPDATE `sao_qq` SET qq_num = REPLACE ( qq_num, '@qq.com', '' );

delete from sao_qq where qq_num not like '%qq.com%'

select * from sao_qq where LENGTH(0+qq_pass)=LENGTH(qq_pass) 判断是否纯数字

delete from sao_qq where length(qq_pass)<9 and LENGTH(0+qq_pass)=LENGTH(qq_pass)

select * from sao_qq where not LENGTH(0+qq_num)=LENGTH(qq_num) // 取不是纯数字
