任宇华 created IOTDB-5487: -------------------------- Summary: Fix the problem that the timestamp is "null" when using jdbc Key: IOTDB-5487 URL: https://issues.apache.org/jira/browse/IOTDB-5487 Project: Apache IoTDB Issue Type: New Feature Components: Client/JDBC Reporter: 任宇华 Attachments: image-2023-02-07-15-02-01-340.png
代码: while (resultSet.next()) { for (int i = 1; i <= columnCount; i++) { int ct = metaData.getColumnType(i); if (ct == Types.TIMESTAMP) { Timestamp rValue = resultSet.getTimestamp(i); if (resultSet.wasNull()) { System.out.println(i + "is null"); } else { System.out.println(i + "value:" + rValue.toString()); } } else { String rValue = resultSet.getString(i); if (resultSet.wasNull()) { System.out.println(i + "is null"); } else { System.out.println(i + "value:" + rValue); } } } } !image-2023-02-07-15-02-01-340.png! Because the last value is null, the lastReadWasNull field is true. An error occurred when using wasNull method to judge. -- This message was sent by Atlassian Jira (v8.20.10#820010)
