Solution 1

You have to user FULL OUTER JOIN
here is the query

SQL

SELECT table1.id, 
CASE WHEN table2.sal IS NULL then 'unmatched'
ELSE 'matched' END  AS status,
table1.name,table1.address
 FROM table1 FULL OUTER JOIN table2 ON TABLE1.id = tables2.id

please mark it as answer if it helps.

Solution 2

Check your table structure if it's right. I don't see a reason to have salary in table2. Anyway, You can get a start from here[^]
