示例1: normalizeMeasurement

// normalizeMeasurement inserts the default database or policy into all measurement names,
// if required.
func (q *QueryExecutor) normalizeMeasurement(m *influxql.Measurement, defaultDatabase string) error {
	if m.Name == "" && m.Regex == nil {
		return errors.New("invalid measurement")
	}

	// Measurement does not have an explicit database? Insert default.
	if m.Database == "" {
		m.Database = defaultDatabase
	}

	// The database must now be specified by this point.
	if m.Database == "" {
		return errors.New("database name required")
