export mysql data to csv file

Question

I am trying to do 2 output data from mysql to a csv file. My code is as follows:

public void exportData(Connection conn,String filename) {
        Statement stmt;
        String query;
        try {
            stmt = conn.createStatement();

            //For comma separated file
            query = "SELECT * into OUTFILE  '/tmp/input.csv' FIELDS TERMINATED BY ',' FROM router ";
            stmt.executeQuery(query);

        } catch(Exception e) {
            e.printStackTrace();
            stmt = null;
        }
    }
}; 

I get the following error at the line where stmt.executequery is called.

java.sql.SQLException: Access denied for user 'nxy'@'%' (using password: YES)
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1075)

    at DBase.exportData(automateExport.java:50)
    at automateExport.main(automateExport.java:18)

I am able to connect to the database properly and even execute basic queries but unable to export data to a .csv file. Please help.

Thank you

You need to have the FILE privilege for your user account to allow for the file to be created at the server host, via a SELECT .. INTO OUTFILE command.
