I like it because it takes into account the use of aliases, but in the explode it does not take into account the passing of a schema through the model, I would like to handle this issue.

private function getFullName(string $table): string
	{

        $tableExploded = explode('.', $table);

        $alias = '';

        if (count($tableExploded) === 2)
        {
            $this->db->schema = str_replace('"', '', $tableExploded[0]);
            $tableName        = $tableExploded[1];
            
        }
        else
        {
            $tableName = $table;
        }


        if (strpos($tableName, ' ') !== false)
        {
            $alias = explode(' ', $tableName);
            $tableName = array_shift($alias);
            $alias = ' ' . implode(' ', $alias);
        }
        

        if ($this->db->escapeChar === '"')
        {
            return '"' . $this->db->getDatabase() . '"."' . $this->db->schema . '"."' . str_replace('"', '', $tableName) . '"' . $alias;
        }
        return '[' . $this->db->getDatabase() . '].[' . $this->db->schema . '].[' . str_replace('"', '', $tableName) . ']' . str_replace('"', '', $alias);;
	}

@hdrodriguez This seems more like a feature request. Please send it in a separate PR after this one will be merged. In this PR we're just fixing a buggy functionality.
