PRIMARY KEY (`employeeID`),
KEY `FK_employeeID_departmentID` (`departmentID`)
) ENGINE=MyISAM AUTO_INCREMENT=9 DEFAULT CHARSET=latin1
here is the model and controller files and view

//id is not posted, just part of url in the link code

}
function deleteemp()
{
//the id is part of the url in the link in the empsview
//using sql in a query, but still using url helper
$this->db->query('delete from tblemployee where employeeID = "'.$this->uri->segment(3).'"');
