Hi all,
I have a query as follows:
Select building, floor from T1
I would like to limit the output where the building, floor combination is present only once in the output.
For example, if the output is
blgdA, 2 bldgA, 3 bldgA, 3 bldgB, 1 bldgB, 2 bldgB, 2
I would like to filter it so that the output is only
blgdA, 2
bldgB, 1
I'm not sure about how to do this.
Can someone help out?
Thanks,
Sashi
