Answer 1

Use Model like this. Use project table as first and boq table as second.
function show_boq($data){
$this->db->select('*');
$this->db->from('project');
$this->db->join('boq', 'project.id = boq.project_id');
$this->db->where('project.id',$id);
$query = $this->db->get();
$result = $query->result();
}
And view file is
<?php
if (is_array($boq) || is_object($boq))
{
foreach ($boq as $row): ?>
<tr>
<td><?php echo $row->id; ?></td>
<td><?php echo $row->item_no; ?></td>
<td><?php echo $row->description; ?> </td>
</tr>
<?php endforeach;
}
?>
