thinkphp分表如何使用

            $field   =   $data[$this->partition['field']];<br />
            switch($this->partition['type']) {<br />
                case 'id':<br />
                    // 按照id范围分表<br />
                    $step    =   $this->partition['expr'];<br />
                    $seq    =   floor($field / $step)+1;<br />
                    break;<br />
.........<br />
            return $this->getTableName().'_'.$seq;<br />

                case 'mod':<br />
                    // 按照id的模数分表<br />
                    $seq    =   ($field % $this->partition['num'])+1;<br />
                    break;<br />
