expdp scott/tiger directory=dp tables=t1  schemas=scott dumpfile=t1.dmp logfile=t1.log  query='"where hiredate>to_date('1982-01-02','yyyy-mm-dd')"'

说明query写的有问题

正确写法要用\转义引号

C:\Users\Administrator>expdp scott/tiger directory=dp tables=t1   dumpfile=t1.dmp logfile=t1.log  query=t1:\"where hiredate>to_date('1982-01-02','yyyy-mm-dd')\"
