在VFP中用select 命令查询表中重复的姓名，为什么不能得到结果?
在一表中有不少姓名重复，用下面的命令为什么查不到结果？select * count(*) from bmk5 group by xm having count(*)>1
谢谢!
1、select * from bmk5 a order by xm where exists (select * from bmk5 b where b.xm==a.xm group by xm having count(*)>1) into cursor temp &&此句代码的含义是什么？
2、为什么下句代码查不出结果吗？
select * count(*) from bmk5 group by xm having count(*)>1
