I want to pick the records with the minimum quantity per package_id
I have these data on TableA
package_id  group_id    quantity
1013        2           8
1013        3           6
1091        4           4
1091        2           8
1014        4           4
and I need to end up to this result
package_id  group_id    quantity
1013        3           6
1091        4           4
1014        4           4
I cannot have a simple Min() because it would Group By group_id as well so I will miss the point.
Thank you
