Magic Tables ?..

Answer / rani

Refer this link which nicely demonstrates the Magic Table.
Magic Table are the INSERTED and DELETED tables which we
cannot see from the database, but can be accessed using
Triggers.
When a new row is added an INSERTED table gets created with
the inserted row. Similarly when a row is updated a DELETED
table is created with the deleted row. For update the old
data is moved to the DELETED table and the new updated row
gets created in the INSERTED table.
