Group by query design help
- by Midhat
Consider this data
PK field1 field2
1 a b
2 a (null)
3 x y
4 x z
5 q w
I need to get this data
select all columns from all rows where field1 has count 1
i tried and finally settled for
select * from mytable where field1 in
(select field1 from mytable group by field1 having count(field1)>1 ) order by field1
but there has to be a better way than this
