查看身份证校验不对的

--select *,KSData.dbo.checkid18(sfzh) from [表] where sfzh<>KSData.dbo.checkid18(sfzh)

更新不对的

--update [表] set sfzh=KSData.dbo.checkid18(sfzh) where sfzh<>KSData.dbo.checkid18(sfzh)

删除年份错的

--delete from [表] where substring(sfzh,7,2)<>'19'

查出月日错的

--delete from [表] where substring(sfzh,11,2)>12 or substring(sfzh,13,2)>31
