## Bug Report
**For English only**, other languages will not accept.
Before report a bug, make sure you have:
- Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues).
- Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview).
Please pay attention on issues you submitted, because we maybe need more details.
If no response anymore and we cannot reproduce it on current information, we will **close it**.
Please answer these questions before submitting your issue. Thanks!
### Which version of ShardingSphere did you use?
we find java version: java8, full_version=1.8.0_282
ShardingSphere-5.1.3-SNAPSHOT
Commit ID: dirty-9dd0d3990c849d50c17c6dc7c92ec2d4ce0ad7e5
Commit Message: Implements openGauss version function by calcite (#19327)
Branch: 9dd0d3990c849d50c17c6dc7c92ec2d4ce0ad7e5
Build time: 2022-08-04T19:57:18+0800
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
ResultSet.getRow() returns the row number of the query result
### Actual behavior
ResultSet.getRow() returns exception
```
Exception in thread "main" java.sql.SQLFeatureNotSupportedException: getRow
at org.apache.shardingsphere.driver.jdbc.unsupported.AbstractUnsupportedOperationResultSet.getRow(AbstractUnsupportedOperationResultSet.java:90)
at com.feature.traffic.mydriver.main(mydriver.java:19)
```
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
```
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class mydriver {
public static void main(String[] args) throws Exception {
Class.forName("org.apache.shardingsphere.driver.ShardingSphereDriver");
String jdbcUrl = "jdbc:shardingsphere:classpath:mode-sharding-databases-tables.yaml";
String sql = "SELECT o.* FROM t_order o WHERE o.user_id=? ";
try (Connection conn = DriverManager.getConnection(jdbcUrl);
PreparedStatement ps = conn.prepareStatement(sql)) {
ps.setInt(1, 1);
try (ResultSet rs = ps.executeQuery()) {
while (rs.next()) {
System.out.println(rs.getRow());//exception
System.out.println(rs.getString(1));
System.out.println(rs.getString(2));
System.out.println(rs.getString(3));
System.out.println(rs.getString(4));
}
}
}
}
}
```
### Example codes for reproduce this issue (such as a github link).
