Description

Unless I'm wrong, I believe SqlIntervalQualifer#getFractionalSecondPrecisionPreservingDefault() returns the wrong field:

  public int getFractionalSecondPrecision(RelDataTypeSystem typeSystem) {
    if (fractionalSecondPrecision == RelDataType.PRECISION_NOT_SPECIFIED) {
      return typeName().getDefaultScale();
    } else {
      return fractionalSecondPrecision;
    }
  }

  public int getFractionalSecondPrecisionPreservingDefault() {
    if (useDefaultFractionalSecondPrecision()) {
      return RelDataType.PRECISION_NOT_SPECIFIED;
    } else {
      return startPrecision;
    }
  }
