在 laravel 查询中获取字段

Question

I have two tables user_master and user_teams with common field user_name. I want to join the table and get the team value group by teams tried as

$filter_teams = DB::table('user_teams')
->join('user_master','user_master.user_name','=','user_teams.user_name')
->whereIn('user_master.geo',$geo)
->groupBy('user_teams.team')
->pluck('user_teams.team')
->toArray();

by may values are duplicating.I'm using postgresql

Answer 1

since you didn't determine select fields... the default will be '*' this is why you are getting duplicated fields...

just add:

->select('user_teams.team') 

and i think that all.

i recommend not using group without aggregation.... so my advice your query to like this:

$filter_teams = DB::table('user_teams')
->join('user_master','user_master.user_name','=','user_teams.user_name')
->whereIn('user_master.geo',$geo)
->select('user_teams.team')->distinct()
->pluck('user_teams.team')
->toArray();
