Answer Posted / sanjay kumar dinda
Cursor is a database object used by applications to
manipulate data in a set on a row-by-row basis, instead of
the typical SQL commands that operate on all the rows in
the set at one time.
Trigger is a database object invoked automatically when any
event occured.
These aevents are
Delete, Insert, Update etc....
SQL server store the intermediate data into to dummy table
INSERTED and DELETED...
At the time of insert operation SQL Server STores inserted
rows into the INSERTED table and at the time of delete or
update SQL Server stores the information into DELETED dummy
table
