But JOIN is the right tool for the job. Why not use it? Is this an interview or test question?

Solution 1

Why not JOIN?
You can still get the required result, though.
Try this-

SQL

SELECT Id,Name, ( SELECT Salary FROM Tab2 WHERE Tab1.Id=Tab2.Id) AS Salary
FROM Tab1

Note: Haven't runned this quey in SSMS but something like this should work.

Thank you Giri. It worked. I have used the correlated sub query in Where clause, but not in select clause.

Learnt one new point :-)
