You have to "specify FULL=Y or provide FROMUSER/TOUSER or TABLES " with the import command in addition to show=y just as the error indicates. But, wouldn't it be easier to just generate the truncate script with a query on the source database like this: select 'truncate table ' || table_name || ';' from dba_tables where <insert desired filter conditions here>; Regards, Brandon ________________________________ Privileged/Confidential Information may be contained in this message or attachments hereto.
