我正在使用Laravel 5.5
,我翻译了以下查询:
'SELECT *
FROM instruments
LEFT join financials on instruments.id=financials.instruments_id
WHERE financials.id IN
( SELECT MAX(financials.id)
FROM financials
GROUP BY financials.instruments_id )
ORDER BY instruments.id ASC'
进入雄辩:
$overviewArray = DB::table('instruments')
->leftJoin('financials', 'instruments.id', '=', 'financials.instruments_id')
->whereIn('financials.id', DB::raw('SELECT MAX(financials.id)
FROM financials
GROUP BY financials.instruments_id )
ORDER BY instruments.id ASC'))->get()->toArray();
但是,我收到以下错误:
在Grammar.php第135行:
Type error: Argument 1 passed to Illuminate\Database\Grammar::parameterize() must be of the type array, object given, called
in C:\Users\admin\Desktop\Coding Projects\laravel_project\vendor\laravel\framework\src\Illuminate\Database\Query\Gramm
ars\Grammar.php on line 250
我的猜测是我的雄辩查询错了?有什么建议吗?
感谢您的回复!

$overviewArray = DB::table('instruments')
->leftJoin('financials', 'instruments.id', '=', inancials.instruments_id')
->whereIn('financials.id', function($query){
$query->select(DB::raw('MAX(financials.id)'))->
from('financials')->
groupBy('financials.instruments_id');})
->orderBy('instruments.id')
->get()
->toArray();
我想会没事的。

就我而言,这是因为我在执行 Event::get(44)
而不是 Event::find(44)
。
