LRM-00116: & #39;) & #39; followed by & #39; yyyy-mm-dd & #39; for oracle 11G EXPDP

For Oracle11G EXPDP

Data between a month of a table should be required

Expdp help = Y

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

So expdp shark/2013 directory = dir_dp dumpfile = traderecord. dmp query = traderecord: "where tr_datetime> = to_date ('2017-03-01 ', 'yyyy-mm-dd') and tr_datetime <to_date ('2017-04-01 ', 'yyyy-mm-dd ')"
LRM-00116: syntax error at ') 'Following 'yyyy-mm-dd'

So add the transfer symbol.
