Re: IQ null values management

Behavior you are seeing for load for Zero length strings into a Null char column in expected.

To achieve the behavior you want , you will need to do following

1. Set option public.Load_ZEROLENGTH_ASNULL=on

2. Modify the load statement to direct IQ  load NULL when there is a blank data.

e.g

, col3 NULL(BLANKS)

Both conditions are essential for the desired effect
