Teradata : Alter table to change primary index to unique primary index
If the table already has a primary index and if it needs to be changed to UPI, for the same column combination,
- First add a USI on the NUPI columns, then execute the below alter command
ALTER TABLE xxx MODIFY UNIQUE PRIMARY INDEX (NUPI_cols)
This will also drop the USI automatically
