Question

注意：使用Lravel 4.1框架

您对POSTGRES DB的我的Sql查询是

$results1 = DB::table('vehicle_brands')
                    ->where('vehicle_brands.caption','ilike', '%'.$_GET['key_word'].'%')
                    ->join('vehicle_manufacturers','vehicle_manufacturers.id', '=', 'vehicle_brands.vehicle_manufacturer_id')
                    ->select('vehicle_brands.*','vehicle_manufacturers.caption AS vm_caption');
                    $results = DB::table('vehicle_brands')
                    ->where('vehicle_manufacturers.caption','ilike', '%'.$_GET['key_word'].'%')
                    ->join('vehicle_manufacturers','vehicle_manufacturers.id', '=', 'vehicle_brands.vehicle_manufacturer_id')
                    ->select('vehicle_brands.*','vehicle_manufacturers.caption AS vm_caption')
                    ->union($results1)
                    ->orderBy('vehicle_brands.caption','ASC')
                    ->get();
                return Response::json(array('status' => true,'data' => $results));

我得到的错误如下：

SQLSTATE [42601]：语法错误：7错误：语法错误在或附近＆＃34;联合＆＃34;第1行：... ilike $ 1 order by＆＃34; vehicle_brands＆＃34;。＆＃34; caption＆＃34; ASC union sele ... ^（SQL：select＆＃34; vehicle_brands＆＃34;。，＃＆34; vehicle_manufacturers＆＃34;＆＃34;字幕＆＃34; as＆＃34; vm_caption＆＃34;从＆＃34; vehicle_brands＆＃34;内部联合＆＃34; vehicle_manufacturers＆＃34;上＃＆34; vehicle_manufacturers＆＃34;＆＃34; ID＆＃34; = ＆＃34; vehicle_brands＆＃34;＆＃34; vehicle_manufacturer_id＆＃34;哪里＃＆34; vehicle_manufacturers＆＃34;＆＃34;字幕＆＃34; ilike％o％order by ＃＆34; vehicle_brands＆＃34;＆＃34;字幕＆＃34; asc union select＆＃34; vehicle_brands＆＃34;。，＃＆34; vehicle_manufacturers＆＃34;＆＃34;字幕＆＃34; as＆＃34; vm_caption＆＃34;从＆＃34; vehicle_brands＆＃34;内部联合＆＃34; vehicle_manufacturers＆＃34;上＃＆34; vehicle_manufacturers＆＃34;＆＃34; ID＆＃34; = ＆＃34; vehicle_brands＆＃34;＆＃34; vehicle_manufacturer_id＆＃34;哪里＃＆34; vehicle_brands＆＃34;＆＃34;字幕＆＃34; ilike％o％）

我在查询中做错了什么？

我使用Laravel 4.1作为框架并使用postgres作为数据库。

我在发布上述问题后进一步研究并找到了我的问题的解决方案，如下所示。

这是一个可以在https://github.com/laravel/framework/pull/3901讨论的错误，讨论也提供了解决方案。

也找到了Stackoverflow解决方案（这与上面相同但是很清楚）

我将我的代码转换为如下：

$query1 = DB::table('vehicle_brands')
            ->where('vehicle_brands.caption','ilike', '%'.$term.'%')
            ->join('vehicle_manufacturers','vehicle_manufacturers.id', '=', 'vehicle_brands.vehicle_manufacturer_id')
            ->select('vehicle_brands.*','vehicle_manufacturers.caption AS vm_caption');
        $query2 = DB::table('vehicle_brands')
            ->where('vehicle_manufacturers.caption','ilike', '%'.$term.'%')
            ->join('vehicle_manufacturers','vehicle_manufacturers.id', '=', 'vehicle_brands.vehicle_manufacturer_id')
            ->select('vehicle_brands.*','vehicle_manufacturers.caption AS vm_caption');
        $query = $query1->union($query2);
$items = DB::table(DB::raw("($querySql order by 'caption' 'ASC') as a"))->mergeBindings($query)
                        ->take($limit)
                        ->skip($limit * ($page - 1))
                        ->get();

$term是搜索关键字。

谢谢。

在UNION查询中的orderBy给出了SQLSTATE [42601]错误
