Hi,
After trying for a week now I've come to the conclusion that help is needed. I've got the following problem:
I have a table with id column, another id (id2) column and a value column. For each id there can be more id2. I want id2 for id where the value is min. I tried several things with having but it doesn't produce what I need. Example:
select id, id2, min(value) from table
group by id
having count (*) >1 and min(value) = (select min(value) from table)
Now it complains about id2 not being part of aggregate.
In order to get the min value I have to group by id, right? But because id2 is unique it won't do min on those values, right? So how do you tackle a problem like that? Any suggestions?
thanks sjors
