Subj:   Re: Unique index vs. primary index
 
From:   Gregg, William

U have duplicates (with respect to the PI).

Run the following query

     Select Prod_Id, count (*)
       From DW_T_Test.Prod
     Group by 1
     Having count (*) > 1
     ;

If even one value of prod-id has a count of 2 or higher, it fails the UPI requirement.

Attempts to insert a duplicate record when a UPI is present will gen an error message.

Good Luck,


Rgrds,

Bill Gregg, Teradata DBA, GE
