NjuptMei opened a new issue, #33678: URL: https://github.com/apache/shardingsphere/issues/33678
### Which version of ShardingSphere did you use? shardingsphere Ver. shardingsphere, 5.4.1 oracle Ver. oracle12c ojdbc Ver. ojdbc8 ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior config： actualDataNodes: ds0.dmg_kettle_conf, ds0.dmg_kettle_config_dmgtmp logicTable: dmg_kettle_config behavior： when executing SQL "select * from dmg_kettle_config order by create_timstmp desc", except the ordered result, the dataTye of **create_timstmp is TimeStamp With Time Zone**, (doesn't support this dataType?) ### Actual behavior when executing SQL "select * from dmg_kettle_config order by create_timstmp desc", the error message "Order by value must implement Comparable." occurs ### Reason analyze (If you can) When executing query, in `oracle.jdbc.driver.OracleResultSetMetaData.getColumnType`, the create_timstmp dataType is 181, and mappings to code -101  and in shardingJdbc, when merging resut, it only transfer the code 93 to java.sql.Timestamp, but the code -101 convert to Object: `org.apache.shardingsphere.sharding.execute.sql.execute.result.MemoryQueryResult.getRows(ResultSet resultSet)`  so, when code running the order executor: `org.apache.shardingsphere.sharding.merge.dql.orderby.OrderByValue.getOrderValues()`, cause this error.  btw: Setting the following parameter: System.getProperties().setProperty("oracle.jdbc.J2EE13Compliant", "true") is ineffective.
