Code

public function testInsertSelectFields() {
  $query = $this->connection
    ->select('test_people', 'tp');

  // The query builder will always append expressions after fields.
  // Add the expression first to test that the insert fields are correctly
  // re-ordered.
  $query
    ->addExpression('[tp].[age]', 'age');
  $query
    ->fields('tp', [
    'name',
    'job',

  // The resulting query should be equivalent to:
  // INSERT INTO test (age, name, job)
  // SELECT tp.age AS age, tp.name AS name, tp.job AS job
  // FROM test_people tp
  // WHERE tp.name = 'Meredith'

  ])
    ->fetchField();

    ->assertSame('30', $saved_age, 'Can retrieve after inserting.');
