Here is a listing of the parameter file and the error I receive. directory=data_pump_dir dumpfile=in_multiplecode_dw.dmp logfile=in_multiplecode_dw.log tables=IN_MUTLIPLECODE query=in_multiplecode:\"where incidentid in (select incidentid from incidentkey where in_date \> TO_DATE('31-dec-2003','dd-mon-yyyy') and in_date \< TO_DATE('01-jan-2006','dd-mon-yyyy'))\" SYNTAX error in QUERY at "(" LRM-00116: syntax error at ')' following ''dd-mon-yyyy'' LRM-00113: error when processing file 'in_mc.par' I have also tried this... directory=data_pump_dir dumpfile=in_multiplecode_dw.dmp logfile=in_multiplecode_dw.log tables=IN_MUTLIPLECODE query=in_multiplecode:\"where incidentid in \(select incidentid from incidentkey where in_date \> TO_DATE \(\'31-dec-2003\',\'dd-mon-yyyy\'\) and in_date \< TO_DATE\(\'01-jan-2006\',\'dd-mon-yyyy\'\)\)\" Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options ORA-39001: invalid argument value ORA-39035: Data filter SUBQUERY has already been specified.
