title: create trigger by checking the value of a field being inserted in oralce
body: <p>I need to create a before insert trigger on <code>TABLE1</code> such that it inserts <code>COL2</code> and <code>COL3</code> of the new row being inserted in <code>TABLE1</code> into <code>TABLE2</code> only when <code>TABLE1.FIELD1 = 'XYZ'</code>. How do I do this so that trigger gets fired only when the condition is met?</p>
