//necessary for Oracle related samples only 
$oci_connection = "some here";

please help me i badly need this to work

connector init for oracle will look similar to next

	require("../../codebase/db_oracle.php"); //extra include

        $res = oci_connect("ERXXA","ERXXA","mldb1003:1521/EXPROJ@TPD");	
	$grid = new GridConnector($res,"Oracle"); //different second param
        //all fields in upper case

Be sure that you have oci extension enabled in php.ini
Also, I’m not quite sure about valid connection string in your case, if the above one doesn’t work - check for more details

Dear user,

Try to put all the column names in uppercase, like that:

    //Initializes connector
	GridConnector c = new GridConnector(connection, DBType.Oracle);
            //configures the used table and fields
