How to delete the reduplicate row in a table?

There are two columns in the table1,
ID|AccountName | ContactName |
1 | ebay.com | Alex
2 | ebay.com |
Look the second row, it is reduplicate info which is absolutely same with
the first row. So I'd like to delete the second row. How to use SQL to do
that?
Cheers,
JimDELETE FROM
SOMETABLE ST
WHERE yourid Column >
(SELECT youridcolumn From sometable ST2 where
ST1.col1 = ST2.col1 AND ST1.col2 = ST2.col2)
--Where
ST1.col1 = ST2.col1 AND ST1.col2 = ST2.col2 is the criteria that matches the
exact data. perhaps put that in a transaction to see if it works
BEGIN TRANSACTION
DELETE ...
Select ... --See the result
--Then Commit or Rollback if not as excpected

I noticed this command: (SELECT MIN(youridcolumn) From sometable ST2 where
which is not what I wanted, becasue I want to remove the row which has NO
ContactName included. It maybe not the MIN(youridcolumn).
So what can I do?|||CEO, This might do what you want:
delete from auction
where id in (select a1.id
from auction a1, auction a2
where a1.account = a2.account
and a1.contact = ' ' and a2.contact != ' ')

f
a missing contact name, I thought this was just a copy & paster error from
you.

SQL statement:
create table auction(
id int,
account varchar(25),
contact varchar(25)
)
go
insert into auction values(1, 'ebay.com', 'Alex')
insert into auction values(2, 'ebay.com', '')
insert into auction values(3, 'aol.com', 'Alexsey')
insert into auction values(4, 'aol.com', '')
insert into auction values(5, 'aol.com', '')
delete from auction
where id in (select distinct a1.id
from auction a1, auction a2
where a1.account = a2.account
and a1.contact = ' ' and a2.contact != ' ')
