sample sample

sample sample

Example queries for copy and past on Demo:

Queries can be simple and complex for several sets of data

{
  Sample_Person{
    Name
    DOB
    FavoriteColors
    Office {
      City
      State
      Street
      Zip
    }
  }
  Sample_Company{
    Mission
    Name
    Revenue
  }
}

Filtering

At the moment, only strict equality is supported:

{
  Sample_Person(id: 116){
    id
    Name
    DOB
    FavoriteColors
    Home {
      City
      State
      Street
      Zip
    }
    Office {
      City
      State
      Street
      Zip
    }
  }
}

Pagination

Pagination is supported through 4 functions that can be combined to achieve the necessary result:

  • after: n – all records with id greater than n
  • before: n – all records with id smaller than n
  • first: n – first n records
  • last: n – last n records
{
  Sample_Employee(after: 120, before: 123){
    id 
    Name
  }

Sample_Person(first: 2){
id
Home {
City
State
Street
Zip
}
}
Sample_Company(last: 3){
id
Name
}
}
