Name of the table for which you want to collect copies of original values of rows that were changed.

Property of



When doing an update( ) or appendUpdate( ), rows will be changed. The original contents of the rows that are changed are copied to the table specified by the changedTableName property. If the table does not exist, it is created. If it does exist, it is erased first so that it contains only those rows that were changed on the last update.

By making copies of the original values of the rows that are changed, you can undo the changes by doing another update( ), using the changedTableName table as the source table.
