Group and apply conditions


Apply limit and conditions per grouped data

Possible duplicate Apply limit and conditions per grouped data . But query is bit different from that. I want to select the student with minimum priority by grouping them by studentId. So that I need student with id 72 with priority 2 and 81 with priority 2 from the given table. Grouping result in all rows since subject id is different. Any help appreciated. DB used is POSTGRES
