Hi,
I am attempting to write a query to return whether or not a particular items value entered is the lowest value and also unique.
For example, if an item as 6 values against it e.g.
user_id item_id value
1 101 3
2 101 3
2 101 4
3 101 1
3 101 1
4 101 5
... the lowest unique value in this is the item with the value 4 because items with values 3 and 1 are not unique and although 5 is also unique it is not the lowest!
i want to find out a query for this....
