Hi I was wondering about the INDEX BY options for Associative Arrays with an INTEGER type. The two options available for this purpose are: BINARY_INTEGER and PLS_INTEGER (do let me know if there is any other type). I believe PLS_INTEGER uses machine arithmetic. But my general observation in the code I've seen through my career, has been the widespread use of BINARY_INTEGER. Is there any specific reason for this? Will I see any significant performance increase if I change the type from BINARY_INTEGER to PLS_INTEGER? Thanks!
