title: TableB which usess column from TableA should update on updating tableA
body: <p>I have two table t1 and t2. T2 uses two columns from t1 and everytime a new record is added to t1, t2 gets a record too. ID is a primary key in t1 and is used to check for duplicate records in t2. Now when my application updates a record on T1, how do I proceed to update t2. New to SQL and learning it myself. Please help me here.</p>
