wht target override?wht advantages it has compare to target update?..

Answer / siva

Target Update (by using Update strategy) will work only
when we have the Primary key in Target. Update override
will happen based on this key.If we don't have the Pkey
Update override will not work.

To overcome the above issue..If our Target is not having
any key column or if we want to update the Target based on
a column other than PKey column then we need to go for
Target Update override option available in Target
properties.
