查询重复记录

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[p_qry]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[p_qry]

/*--查询重复记录的通用存储过程

可以查询出表中那些数据是重复的,这里的重复,是指除主键外重复的记录
如果表中有主键,请指定主键.
如果表中有标识字段,而且标识字段无重复,请在调用时,将主键指定为标识字段
如果标识字段重复,不能用此存储过程

create proc p_qry
@tbname sysname, --要查询的表名
@keyfdname sysname=null --表中的主键,如果未指定,则表中无主键

--调用示例
--创建测试数据
create table 表(f1 int,f2 int,f3 int,f4 int,f5 int)
insert into 表
select 1,1,1,1,1
union all select 2,1,1,1,1
union all select 3,2,1,23,1
union all select 4,2,3,1,3
union all select 5,1,1,1,1
go

--调用通用存储过程实现楼主的查询
exec p_qry '表','f1'

--删除测试环境
drop table 表
