BUMP

connector init for oracle will look similar to next

	require("../../codebase/grid_connector.php");
	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
	$grid->render_table("EMPLOYEES","EMPLOYEE_ID","FIRST_NAME,LAST_NAME");

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 php.net/oci_connect 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
	c.dynamic_loading(200);
	c.render_table("SS_REMOTE_MACHINES", "ID", "HOST,NAME,DESCRIPTION,METHOD,REMOTE_ID,LAST_UPDATED");
