Syntax error trying to update multiple tables in codeigniter - php

Question

I'm trying to update multiple joined tables in codeigniter but it is giving the following error:
Error Number: 1064
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near '.carro_id INNER JOIN a ON ac.atributo_id = a.id INNER JOIN
m ON c.`modelo_' at line 1
UPDATE `carro c, atributo_carro ac, atributos a, modelos m, marcas ma
INNER JOIN ac ON c`.`id = ac`.`carro_id INNER JOIN a ON
ac`.`atributo_id = a`.`id INNER JOIN m ON c`.`modelo_id = m`.`id INNER
JOIN ma ON m`.`marca_id =` `ma`.`id` SET `marcas`.`marca` = 'Opel',
`modelos`.`modelo` = 'AMmmmmm', `carro`.`kilometragem` = '12000',
`carro`.`cor` = 'Azul', `carro`.`ano` = '1992', `carro`.`descricao` =
'dfghjk', `carro`.`valor` = '1288.00', `atributos`.`atributo` =
'rapido' WHERE `carro`.`id` = '10'
This is my function to update.
public function update_carro_query($id, $data)
{
// print_r($data); die();
$query =
$this->db->set('marcas.marca', $data['marca']);
$this->db->set('modelos.modelo', $data['modelo']);
$this->db->set('carro.kilometragem', $data['kilometragem']);
$this->db->set('carro.cor', $data['cor']);
$this->db->set('carro.ano', $data['ano']);
$this->db->set('carro.descricao', $data['descricao']);
$this->db->set('carro.valor', $data['valor']);
$this->db->set('atributos.atributo', $data['atributo']);
$this->db->where('carro.id', $id);
$this->db->update('carro c, atributo_carro ac, atributos a, modelos m, marcas ma INNER JOIN ac ON c.id = ac.carro_id INNER JOIN a ON ac.atributo_id = a.id INNER JOIN m ON c.modelo_id = m.id INNER JOIN ma ON m.marca_id = ma.id');
return $query;
}
This is my database tables and relationships
The query is generated by the function. What can be causing the syntax error? Am i missing something?

Answer 1

The update() method only expects a table name as first parameter, not a complete statement including a join and more. So it'll wrap the first parameter into backticks. This leads to the sql syntax error you have.
Better use query() to generate your (not straightforward) update statement.
