MSSQL查询2个字段一起重复语句错误~HELP
我要查询inventory表,字段broken与nameid一起重复的记录,构造如下语句,出错,返回',' 附近有语法错误。据说in只能有1列,要用and,求助如何修改~~~~
select * from inventory a
where (a.broken,a.nameid) in (select broken,nameid from inventory group by broken,nameid having count(*) > 1)
补充：一楼的语句可以成功执行,但是返回结果nameid没有重复,broken重复的记录也列出了.....
答案：select * from inventory a
join (select broken,nameid from inventory group by broken,nameid having count(*) > 1) b on a.broken=b.broken and a.nameid=b.nameid
其他：select * from inventory a
where (a.broken+a.nameid) in (select broken+nameid from inventory group by broken,nameid having count(*) > 1)
