Hi there,

I have the following query:

select blue, red, green, id, height
from table1
group by blue, red, green, id, height
having count (*) =1

The matter is that HAVING COUNT I just want to count the Id's, not the other columns that I have in group by.

Any tips?

Thank you

do you mean this?


select blue, red, green, id, height
from table1
group by blue, red, green, id, height
having count (id) =1

Depends on what your data is and what you want for output. With over a hundred posts I'm surprised you still don't post sample data and expected output. If you want to provide that we can certainly help you out.
