I\'m trying to export data from a query into a csv file from Oracle Enterprise Express installed on a Windows Server 2008 machine.
I\'ve found this solution:
As user: h_djebli pointed out in his comment you need to be connected as SYS user in the first place.
To do that, you have to be in your oracle home directory :
cd $ORACLE_HOME
Then execute :
sqlplus / as sysdba
sqlplus will start in your terminal and you'll be connected as the SYS user.
You can finally write the GRANT command in your sqlplus console :
GRANT EXECUTE ON SYS.utl_file TO your_db_username;
