Laravel 5 SQLSTATE[42S22]: 找不到列
Laravel 5 SQLSTATE[42S22]: Column not found
我正在做一些连接并试图获取数据。我的查询生成器是：
$datasource = DB::table('vehicles')->join('brands', 'vehicles.brand_id', '=', 'brands.id')->join('sections', 'vehicles.section_id', '=', 'sections.id')->select('vehicles.*, vehicles.id AS vid');
但是我收到这个错误：
SQLSTATE[42S22]: Column not found: 1054 Unknown column
'vehicles.model,' in 'field list' (SQL: select vehicles.model, as
AS from vehicles inner join brands on vehicles.brand_id =
brands.id inner join sections on vehicles.section_id =
sections.id limit 4 offset 0) Line 620
我做错了什么？
你应该使用 selectRaw() 而不是 select():
->selectRaw('vehicles.*, vehicles.id AS vid');
