RE: How to create 2 unique indexes (Field1, Field2) and (Field1,

Hi,

The second index failed because of dups found. You will need to check the data and correct them before creating the index. The following should tell you which ones have dupl. values and how many occured:

SELECT ACCTNO,PAYGRP,count(*) from SPY_ADHOC_PAYMENT group by ACCTNO,PAYGRP having count(*) > 1;

HTH,
Ross
