    Comment on it

    Hello readers, today we will discuss about the "SQL query with INNER JOIN".

    UPDATE 
    (SELECT table1.value as OLD, table2.CODE as NEW
     FROM table1
     INNER JOIN table2
     ON table1.value = table2.DESC
     WHERE table1.UPDATETYPE='blah'
    ) t
    SET t.OLD = t.NEW
    

    The above query will update the data in table1 and table2.

    here we are updating the table1 data like :- WHERE table1.UPDATETYPE='blah'

    I hope it helps you.

    Thank-you readers.
