oracle10g - SQL query , How to select a generated field in GROUP BY -
I'm trying to select two things: customer_id and segment (based on some arguments), both of them Should be in the group
I tried to use without the surname (like giving it to the case ... END) but it failed because it has the MAX GROUP BY field area if I cut the maximum It also fails to compile it.
What should I do to keep this in mind?
I'm not sure that you have already " Why do I strongly believe that by removing the "group by" section from your query, you will get the information you expected.
