EXPDP HELP=Y

QUERY
Predicate clause used to export a subset of a table.
For example, QUERY=employees:"WHERE department_id > 10".

於是  expdp shark/2013 directory=dir_dp dumpfile =traderecord.dmp query=traderecord:"where tr_datetime >= to_date('2014-03-01','yyyy-mm-dd') and tr_datetime < to_date('2014-04-01','yyyy-mm-dd')"
LRM-00116: syntax error at ')' following 'yyyy-mm-dd'

於是要加轉移符號 

]expdp shark/2013 directory=dir_dp dumpfile =traderecord.dmp query=traderecord:\"where tr_datetime \>= to_date\(\'2014-03-01\'\,\'yyyy-mm-dd\'\) and tr_datetime \< to_date\(\'2014-04-01\',\'yyyy-mm-dd\'\)\"
