sql 查询到 laravel 查询与联合

Question

我想将下面的联合查询转换为 laravel 查询

DB::select("select lead_master.lead_stage from lead_master inner join  user_master on 
user_master.user_name=lead_master.assigned_user_name where region in (".$geo_string.") and teams 
in (".$filter_teams_string.") group by (lead_stage) union
select  meeting_hash from meetings_master where assigned_user_name in 
(".$filter_username_string.") and meeting_hash in ('follow_up','first_time') group by 
(meeting_hash) 
 union
 select sales_stage from opportunity_master where sales_stage in ('Identified','QO_to be 
 approved') and assigned_user in (".$filter_username_string.") group by (sales_stage)");

以下查询在 postgre 中运行良好

Answer 1

在此开始之前，我假设您了解laravel Eloquent

假设您的lead_master表是LeadMaster Model ，也是MeetingsMaster和OpportunityMaster

$lead_master = LeadMaster::select("lead_master.lead_stage as stage")
    ->join('user_master','user_master.user_name','=','lead_master.assigned_user_name')
    ->whereIn('region',$geo) //$geo is an array
    ->whereIn('teams',$filter_username) //also an array
    ->groupBy('lead_stage');

$meetings_master = MeetingsMaster::select('meeting_hash as stage')
    ->whereIn('assigned_user_name',$filter_username)
    ->whereIn('meeting_hash',['follow_up','first_time'])
    ->groupBy('meeting_hash');

$opportunity_master = OpportunityMaster::select('sales_stage as stage')
    ->whereIn('sales_stage',['Identified','QO_to be approved'])
    ->whereIn('assigned_user',filter_username)
    ->groupBy('sales_stage');

$query = $lead_master->union($meetings_master)->union($opportunity_master)->pluck('stage'); //your result
dd($query);

这就是您使用Laravel Eloquent时的样子

ps：你不需要为此做3个变量，我只是用它来方便维护
