QDB_Select 实现对字段名映射的支持 #50

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
映射名是指可以在查询参数中使用映射名作为字段名。QDB_Sele
ct 会负责在生成查询时将映射
名转换为实际的字段名。

例如：

{{{
$select->columnMapping('title', 'post_title')
       ->where(array('post_title' => $title));
// 生成的查询条件是 `title` = {$title} 而不是 `post_title` = {$title}
}}}

通过 QDB_Select::columnMapping() 方法设置字段名映射。
