How to delete rows in a table are same identical rows in all the fields where clause column. Recently, i got this from one of my friend.

 

create table tbl_delete (id int, name varchar(30))

insert into tbl_delete values (1,'Muthu')

insert into tbl_delete values (1,'Muthu')

insert into tbl_delete values (2,'SQL')

insert into tbl_delete values (2,'SQL')

-- Two rows are same with all fileds

select * from tbl_delete WHERE id =1

Begin tran

SET ROWCOUNT 1

DELETE FROM tbl_delete WHERE id =1

SET ROWCOUNT 0
-- Run this when you see (1 row(s) affected), otherwise rollback tran

Commit tran


Hope this help someone.
