As the topic says, when setting cardinality, what does changing the operator do?
I awlays have it on = but am currious to know what the other operators did and when they are used.
Thanks
Perform a search on theta joins!!
Basically this is a vast subject where you will learn about cartesian products (cross joins), triangular joins ( < , > ), non-equi joins (<>) and 'between' joins. They can all have their specific use, but since this is a Cognos forum I'll try and keep quiet ;)
In regular models you will not use anything else than = , mind you!!
