WHAT IS UPDATE OVERRIDE . DIFFERENCE BETWEEN SQL OVERRIDE
AND UPDATE OVERRIDE ?

Answer Posted / vishnu_kr

Hi,

i guess the SQL override is used in the source qualifier trf
to implement joins, filter, sorter etc..

but update override is used in the Target table definition.
u use this option to update Targets that have no primary
key (hence u can't use update strategy) coupled
with 'Update as update' property in the session mappings tab
and 'Treat rows as' property set as 'Update' in the session
Properties tab.

Is This Answer Correct ?    25 Yes 3 No
