我有一张表 HouseholdProfile hasMany HouseholdMembers 。我想查询所有HouseholdProfile的附加字段,其中包含特定配置文件的成员数。
我想要的是什么:
ID Profile No of Dependents
1 Greg 3 <--- 3 is Number of child record in member table
2 Roger 2
我已尝试过以下查询,但我认为它缺少一些东西
$query = HouseholdProfile::whereExists(function ($query) {
$query->select(\DB::raw(count('household_members.id')))
->from('household_members')
->whereRaw('household_members.household_profile_id = household_profiles.id');
})
->where('disaster_risk','like','%1%')->get();
答案 0 :(得分:1)
如果您没有明确需要包含子计数的额外列,那么您可以急切加载关系:
hive>create table testTableNew(id int ,name string ) clustered by (id) into 2 buckets stored as orc TBLPROPERTIES('transactional'='true');
然后您可以访问模板中每条记录的计数,如下所示:
$results = HouseholdProfile::with('household_members')
->where('disaster_risk','like','%1%')
->get();
