when every there is a change in the source database, those changes only has to reflect in the target table.
It should not delete all the rows or drop the target table and recreate the table and load all the records.

what all the load properties has to change in the target table.

source table can be any thing and target table can be any.

ok, take source as MS Access and target table MS SQL Server database table.

when i run the procedure/mapping in iway, it should display number of rows updated for the updated rows and number of rows inserted for newly inserted rows.

please go through my above posts also.

Renuka,

I assume that you are talking about iWay ETL manager. The way you do it if the target object is an RDBMS is to use the Preprocessing option on the Load object. You select the option update the existing record.

But be careful preprocessing is very costly in times of run time as iWay no starts comparing the input with what is already in the target before it decides what rows to update.
