Hi

One way would be to do

select dodaac, msn, contract, count(*)
from table
group by dodaac, msn,contract
having count(*) >1

There is also a feature in Oracle that will send all the bad records to an
exception table if it violates a constraint but you'll have to read the
fine manual to find out how it works.

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 ???


TIA
