Question

我有两个查询：

查询1

$usersdetails = DB::table('users as a')
    ->join('Appraiser_commands as b', 'a.id', '=', 'b.user_id')
    ->select('a.id as userid', 'b.cycle_id as cycleid', 'a.name as uname', 'b.mode as mode')
    ->where('a.head_id', '=', $id)
    ->where('b.mode', '=', 'proceed')
    ->get()->toArray();

查询2

$usersdetailsApp = DB::table('users as a')
    ->join('Appraiser_commands as b', 'a.id', '=', 'b.user_id')
    ->select('a.id as userid', 'b.cycle_id as cycleid', 'a.name as uname', 'b.mode as mode')
    ->where('b.mode', '=', 'Approved')
    ->get()->toArray();

两个查询都运行良好。我试图将两个查询合并为一个查询，所以我尝试了

$usersdetails = DB::table('users as a')
    ->join('Appraiser_commands as b', 'a.id', '=', 'b.user_id')
    ->select('a.id as userid', 'b.cycle_id as cycleid', 'a.name as uname', 'b.mode as mode')
    ->where('a.head_id', '=', $id)
    ->where('b.mode', '=', 'proceed')
    ->orWhere('b.mode', '=', 'Approved')
    ->get()->toArray();

但这不起作用。我是laravel的新手，请帮助。

Answer 1

尝试一下：

$usersdetails = DB::table('users as a')
    ->join('Appraiser_commands as b', 'a.id', '=', 'b.user_id')
    ->select('a.id as userid', 'b.cycle_id as cycleid', 'a.name as uname', 'b.mode as mode')
    ->where(function ($query) use ($id) {
        $query->where('a.head_id', $id)->orWhereIn('b.mode',
            ['proceed', 'Approved']);
    })
    ->get()->toArray();

Answer 2

尝试这个

$usersdetails = DB::table('users as a')
    ->join('Appraiser_commands as b', 'a.id', '=', 'b.user_id')
    ->select('a.id as userid', 'b.cycle_id as cycleid', 'a.name as uname','b.mode as mode')
    ->where('a.head_id', '=', $id)
    ->where(function($query){
         $query->where('b.mode', '=', 'proceed');
         $query->orwhere('b.mode', '=', 'Approved');
     })
    ->get()->toArray();

使用where group，您可以创建and or查询组，以更好地实现明智的结果组

Answer 3

在查看查询时，查询2中没有->where('a.head_id', '=', $id)。

删除该条件并将head_id添加到选择项中，以便之后可以手动检查head_id是否匹配：

$usersdetails = DB::table('users as a')
    ->join('Appraiser_commands as b', 'a.id', '=', 'b.user_id')
    ->select('a.id as userid', 'b.cycle_id as cycleid', 'a.name as uname', 'b.mode as mode', 'a.head_id as headid')
    ->where('b.mode', 'proceed')
    ->orWhere('b.mode', 'Approved')
    ->get()->toArray();

将两个查询合并为单个Laravel
