When the
Exportstatement specifies thedelete_existing_filesproperty, eachOutfilestatement generated by theExportwill carry this property. This causes eachOutfilestatement to delete existing files, so only the result of the last Outfile statement will be retained.So, we add a rpc method which can delete existing files for
Exportstatement and theOutfilestatements generated by theExportwill not carrydelete_existing_filesproperty any more.
