Hi, Bodla, Sravan Kumar wrote:
No. If the table has a unique index (either upi or usi) then you will ** not ** have a problem with 'duplicate row checks'. The only time you have problems with duplicate row checks is when: - the table is SET, AND - the table has NO unique indexes, AND - you have lots of rows with the same PI rowhash value. If any of the above conditions are NOT met then you will not have a problem with duplicate row checks during insert processing.
