Answer 1

Simply Use Inner Join

SELECT A.*, B.UAS
FROM tbl1 AS A JOIN tbl2 AS B ON A.StudentID = B.StudentID AND A.SubjectID = B.SubjectID

Answer 2

SELECT t1.*, t2.UAS
    FROM uts AS t1 
    LEFT JOIN uas AS t2
        ON t1.StudentID = t2.StudentID AND t1.SubjectID = t2.SubjectID

You just have to join the two tables on the two common columns.

Answer 3

A JOIN clause is used to combine rows from two or more tables, based on a related column between them.

   select t1.*,t2.UAS from table1 t1 
     inner join table2 t2 
     ON t1.StudentID = t2.StudentID AND
     t1.SubjectID = t2.SubjectID
