Accessing Hashed Files using UV stage.
Posted: Tue Feb 24, 2004 1:20 am
Hi,
is there an performance improvement if we dump an odbc table in to a hash file and look up this hash file using an UV stage instead of looking up the odbc table directly.
The reason why i am using an UV stage is that i have ' >' and '<' in look up conditions, and this can be achieved only through UV stage.
The odbc table size is 50- 60 k records.
