Question

Is it possible to update a column of a table from two optional tables, in Oracle. I mean, there are 2 tables whose columns are exactly same and, according to input Id, I want to update related table.
For eg.

UPDATE CASE WHEN EXISTS (
    SELECT A.ID FROM Table_A A 
    WHERE  A.ID = 'B1'
    )
    THEN
      Table_A A 
      SET A.Status = '0'
      WHERE A.ID = 'B1'
    ELSE
      Table_B B
      SET B.Status = '0'
      WHERE B.ID = 'B1'

Where Table_A and Table_B has exactly same columns with different records.

Thank you.

BEGIN
UPDATE Table_A A SET STATUS = ‘0’ WHERE A.ID = #ID#;
if sql%notfound then
UPDATE Table_B B SET STATUS = ‘0’ WHERE B.ID = #ID#;
END IF;
END;
