Boolean
true
Purpose
The DropHistoricalTableOnAddExisting parameter controls the behavior when you add an existing property or method to a historical table in an RPS mapping. The default value of true specifies that the historical table is dropped if an existing property or method is added.
If you want to retain a historical table (rather than drop the table) when an existing property or method is added, set the value of this parameter to false. When the alter table script is created, ALTER TABLE <> ADD is then used to modify the table. Any existing rows will have a column value of NULL.
