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")
}
// Find database.
di, err := q.MetaStore.Database(m.Database)
if err != nil {
return err
} else if di == nil {
return ErrDatabaseNotFound(m.Database)
}
// If no retention policy was specified, use the default.
if m.RetentionPolicy == "" {
if di.DefaultRetentionPolicy == "" {
return fmt.Errorf("default retention policy not set for: %s", di.Name)

// if required.
func (q *QueryExecutor) normalizeMeasurement(m *influxql.Measurement, defaultDatabase string) error {

// the same as the measurement name it came from in the FROM clause.
