I thought this would have been a simple query but I'm stuck.
I have a table that has a field that should have unique data but doesn't. I'm trying to get results that will return only the rows that have data that has more than one unique value.
So if field A has values
20
30
30
40
50
50
50
I only want rows that have more that the one unique value, in this case, the rows with 30 and 50.
