TDataGridColumn trazendo um SELECT de outra tabela

Claudio Colares 07/02/2021 (há 3 anos)

Queria preencher a TDataGridColumn 'movimento_estoque' com o resultado do select:
select sum(quantidade_estoque) as total from produto_movimento where id_produto = [id do produto da linha processada]

Poderiam me ajudar ?

No MODEL ProdutoMovimento criei esse método, porém dá erro... não encontra o "$this->id_produto"

<?php
public static function get_saldo()
{
TTransaction::open('local');
$conn = TTransaction::get(); // get PDO connection
$query = 'select sum(quantidade_estoque) as total from produto_movimento where id_produto = '.$this->id_produto;
$sth = $conn->query($query);
$sth->execute();
$result = $sth->fetchAll();
$result = $result[0];
return $result;
}
?>
