Changing input field from XXXWhereInput from String to Int

[saschaseniuk]

Connecting to MySQL works fine.

Unfortunately the fields in the inputs (XXXWhereInput) doesn't match the corresponding table.

type Modelle {
  #
  id: Int!
  #
  hersteller_id: Int
  #
  hersteller_name: String
  #
  modell_id: Int
  #
  modell_name: String
}

#
input ModelleWhereInput {
  #
  id: String
  #
  hersteller_id: String
  #
  hersteller_name: String
  #
  modell_id: String
  #
  modell_name: String
}

How can I change "hersteller_id: String" to "hersteller_id: Int"?
