             Summary: Implement ResultSet.getBytes()
                 Key: HIVE-7134
                 URL: https://issues.apache.org/jira/browse/HIVE-7134
             Project: Hive
          Issue Type: Improvement
            Reporter: Bill Oliver


I'd like to see an implementation of ResultSet.getBytes().

Here is my (untested) implementation. This could certainly be improved upon.

	public byte[] getBytes(int columnIndex) throws SQLException {
		Object value = getColumnValue(columnIndex);
		if (wasNull) {
			return null;
		}
		if (value instanceof byte[]) {
			return (byte[]) value;
		}

		try {
			// this implementation will work on any Object that implements java.io.Serializable
			// includes Number, Date, Timestamp, or String
			ByteArrayOutputStream b = new ByteArrayOutputStream();
			ObjectOutputStream o = new ObjectOutputStream(b);
			o.writeObject(value);
			return b.toByteArray();
		} catch (IOException e) {
			throw new SQLException(e);
		}
	}

  public byte[] getBytes(String columnName) throws SQLException {
    return getBytes(findColumn(columnName));
  }
