Subj:   Re: Deleting Duplicates with a single DELETE statement
 
From:   Thyagarajan, Vivek

Guys,

Thanks for all your response.

I never knew that I could use ROWID in Teradata. That's what I use all the time in Oracle.

Below is my SQL which deletes all duplicates:

     delete from  vthyagar.Inv_Header a
     where a.rowid
     >(
     select min(b.rowid)
     from vthyagar.Inv_Header  b
     where a.Invoice_Nbr=b.Invoice_Nbr
     and a.Company_Cd=b.Company_Cd)
     ;
