    Is this a college assignment?
    Here is a hint, you have to update table S2 when S2.ecode = S1.ecode.

    If your table S2 dones no contain SAL column and if you want than 1st you have to add that column in S2 table using

    alter table s2 add (sal number());

    after that you can update this column as PAVB suggested.

    Your update will need to look like this:

    UPDATE s2
    SET s2.sal = (SELECT s1.sal
    FROM s1
    WHERE s2.ecode = s1.ecode)

    OP stated he wants to learn so IMHO this is the wrong approach... "give a man a fish, and you feed him for a day, teach him to fish, and you feed him for a lifetime".

    I agree to an extent, but nearly a week after originally posting 'its urgent plz provide the solution to this query', and not seeming any closer to a solution, I thought it time to counter some of the more sardonic replies the OP had received.

    got you but, this wasn't a production issue therefore no "urgent plz..." applies.
