# query to update MV table:

mutation MyMutation($input: UpdateTableInput = {id: "mie-temp-mv", tags: [{name: "mie2"}], _version:5}) {
  updateTable(input: $input) {
    id
    tags {
      name
    }
    _version
  }
}

# _version is necessary. specify the given version

The query above will add
	tags: [{name: "mie2"}]
to the existing datebase.
