Update columns

Update columns

Update columns are columns that uniquely identify rows in the target table. Add update columns when the database target table does not contain a primary key and the
data transfer
task uses an update, upsert, or delete operation.
When you run the
data transfer
task, the task uses the field mapping to match rows in the source to the database table. If the
data transfer
task matches a source row to multiple target rows, it performs the specified task operation on all matched target rows.
