Re: SQL PROBLEM for duplicate rows..
I am sorry I made a mistake in naming . Correct one is below: delete from table_name where rowid not in (select maxrowid from (select column1,column2, max(rowid) maxrowid from table_name group by column1,column2)); - Original Message - To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> Sent: Friday, May 25, 2001 1:22 PM > I think this query eliminates the duplicated rows: > > delete from table_name where rowid not in (select maxrowid from (select > column1,column2, max(rowid) maxrowid from den group by column1,column2)); > > - Original Message - > To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> > Sent: Friday, May 25, 2001 1:01 PM > > > > Hi > > > > Table A got some duplicated rows..

Re: SQL PROBLEM for duplicate rows..
I think this query eliminates the duplicated rows: delete from table_name where rowid not in (select maxrowid from (select column1,column2, max(rowid) maxrowid from den group by column1,column2)); - Original Message - To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> Sent: Friday, May 25, 2001 1:01 PM > Hi > > Table A got some duplicated rows..
