Выдержка из SQL Server BOL:
============================
Two special tables are used in trigger statements: the deleted table and the inserted table. Microsoft® SQL Server™ 2000 automatically creates and manages these tables. You can use these temporary, memory-resident tables to test the effects of certain data modifications and to set conditions for trigger actions; however, you cannot alter the data in the tables directly.
The inserted and deleted tables are used primarily in triggers to:
-Extend referential integrity between tables.
-Insert or update data in base tables underlying a view.
-Check for errors and take action based on the error.
-Find the difference between the state of a table before and after a data modification and take action(s) based on that difference.
