Access denied. You need the FILE privilege for this operation

[hirakumar maharjan]

I am testing to back the database into my computer's disk. While I backup the database into my computer. I got problem of "Access denied. You need the FILE privilege for this operation". How could I backup to my hardDisk.

$lock=mysql_query("LOCK TABLES onetable READ,twotable READ") or die (mysql_error());

echo "Sucess Lock Process<BR><BR \>";



echo "BACKUP PROCESS:<BR \>";
