Create an Insert Trigger named ‘tgNoInsertBook’ on the Borrows table. This trigger must check data inserting, if number of borrower greater than book’ quantity it will be rollback and display a message “Out of stock” Example: if user insert a row (using: Insert into Borrows Values(10,1,4,getdate()) to Borrows table, no row will be inserted and message “Out of stock” will be displayed 13.
