HAVING COUNT(*) >= 10;
I want to use this query to return instances of the C.PHR_C_ID that are more than or equal to 10. However, when I limit my select statement to that column I get the desired result but when I add all these columns to it 'having count' returns 0. There are more than zero records; I think there is something wrong with the query.

Answer 1

The problem is that when you add in your fields and GROUP BY them, you get a count of records for that distinct list of fields. You can probably switch to a QUALIFY statement instead. This will sum up the results by distinct C.PHR_C_ID ignoring the other fields, and then return any fields for that distinct C.PHR_C_ID which has a count(*) >= 10.
