Builder query question From table AS table01, table AS table02

#1
I would like to make a Builder Query base on

PHP Code:
$tQRY "SELECT node.*
         FROM "
.$this->dbTable." AS node,
              "
.$this->dbTable." AS parent
         WHERE node.LFT BETWEEN parent.LFT AND parent.RGT
              AND parent.NAME = '"
.$node."'
         ORDER BY node.LFT"
;
$query $this->db->query($tQRY);
$this->dbLastQuery =  $this->db->getLastQuery(); 

Result of this query :

Code:
SELECT node.*
FROM da_mainmenu AS node, da_mainmenu AS parent
WHERE node.LFT BETWEEN parent.LFT AND parent.RGT AND parent.NAME = 'Elektriciteit'
ORDER BY node.LFT

When is transform it to a full builder
PHP Code:
$builder $this->db->table($this->dbTable);
$builder->resetQuery();
$builder->select('node.*');
$builder->from($this->dbTable .' AS node');
$builder->from($this->dbTable .' AS parent');
$builder->where('node.LFT BETWEEN ''parent.LFT AND parent.RGT');
$builder->where('parent.NAME '$node);
$builder->orderBy('node.LFT');
$query =  $builder->get(); 

with following result
Code:
SELECT node.*
FROM da_mainmenu, da_mainmenu AS node, da_mainmenu AS parent
WHERE node.LFT BETWEEN 'parent.LFT AND parent.RGT' AND parent.NAME = 'Elektriciteit'
ORDER BY node.LFT

I get the first da_mainmenu to much.
So there is problem with

PHP Code:
$builder->from($this->dbTable .' AS node');
$builder->from($this->dbTable .' AS parent'); 

How can i transform the query to builder?
Also I'm not sure how to do the 'WHERE X BETWEEN y  AND Z'
** solved **

Class is included

Just code the where clause directly, like so:

Code:
$builder->where('node.LFT BETWEEN parent.LFT AND parent.RGT');

There's no variable interpolation or substitution so it should be fine.

Thanks

Also problems solved with the table selection
PHP Code:
$this->db db_connect($this->dbActiveGroup);

$builder $this->db->table("$this->dbTable AS da_node,  $this->dbTable AS da_parent");
$builder->resetQuery();

$builder->select("da_parent.*");
$builder->where("da_node.LFT BETWEEN da_parent.LFT AND da_parent.RGT");
$builder->where("da_node.NAME "$node);

$builder->orderBy("da_parent.LFT");

$query =  $builder->get();
$this->dbLastQuery =  $this->db->getLastQuery();
return 
$query
