George,

Here is one way:

select distinct a.DODAAC,b.NSN,c.CONTRACT count(*) from tablea a, tableb b, tablec c
where (whatever your where clause is)
group by a.DODAAC,b.NSN,c.CONTRACT
having count(*) > 1

This will give you the PK values of those records from your select where you are producing duplicate values.

You could obviously use the 'distinct' clause in your insert statement to produce unique PK's, but this may notbe what you want.

hope this helps

Good Morning,

I am selecting information from 3 tables and inserting it into a new table. My compound primary key is composed of:

  DODAAC       VARCHAR2(6)
  NSN              VARCHAR2(13)

CONTRACT VARCHAR2(14) The results BEFORE I put the PK on the INSERT resulted in about 650,000 records. After I put the PK in I am getting: ORA-00001: unique constraint (SHOPPINGSA.SCAN_CONTRACT_PK) violated

How do I find the bad data ???
