Solution 2

SQL

SELECT sm.rollno, sm.name, sm.[any other column name] FROM Student_mst sm
WHERE NOT EXISTS
(
SELECT * FROM medical_mst mm WHERE mm.rollno = sm.rollno

Solution 1

you can make your query something like this...

SQL

SELECT Student_mst.* FROM Student_mst
WHERE rollno NOT IN (SELECT rollno FROM medical_mst)
