ORA-00933: SQL command not properly ended

Hi folks
I am trying to export the table data to a text file using the following sql query :

SELECT * FROM departments INTO OUTFILE C:/outfile.txt ;

When the command is run on a sql editor , it gives the following error -

Error code 933, SQL state 42000: ORA-00933: SQL command not properly ended

Please help sort out this error.

Thank you
