- 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, full_path=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.282.b08-1.el7_9.x86_64/bin/java

Commit ID: dirty-bcde6f374c4a3a025173fbc9f6d0e66ed686a042
Commit Message: Fix fetch forward all error in openGauss(#21421) (#21471)
Branch: bcde6f374c4a3a025173fbc9f6d0e66ed686a042
Build time: 2022-10-11T19:13:56+0800
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
drop table if exists t_broadcast;
create table t_broadcast(id int,c_id int,a int,b text);
insert into t_broadcast values (1,1,10,'test1'),(1,2,10,'Test12'),(1,2,null,'test12'),
(2,1,20,'test21'),(2,2,20,'test22'),(2,3,null,'Test22'),
(3,3,null,'test3'),(3,3,null,'test3'),(3,1,null,'test31'),(4,4,40,'test4'),(5,5,50,'Test5'),(6,6,60,'test6'),
(7,4,74,'test74'),(8,5,85,'test85'),(9,5,50,'test95'),(10,6,106,'test106');
--excute SQL by gslq success
```
start transaction;
cursor cur_test_01 for select id,sum(c_id) from t_broadcast group by id order by 1,2;
fetch from cur_test_01;
fetch all from cur_test_01;
close cur_test_01;
end;
```
--excute SQL by using JDBC failed
```
String tb_name = "t_broadcast";
stmt = connection.createStatement();
stmt.execute("start transaction;");
stmt.execute("cursor cursor1 for select id,sum(c_id) from " + tb_name + " group by id order by 1,2;");
ResultSet resultSet = stmt.executeQuery("fetch from cursor1;");
while (resultSet.next()) {
System.out.println(resultSet.getRow());
System.out.println(resultSet.getInt(1));
System.out.println(resultSet.getInt(2));
System.out.println(resultSet.getString(3));
System.out.println(resultSet.getString(4));
}
```
### Actual behavior
gsql and jdbc
```
Exception in thread "main" org.opengauss.util.PSQLException: [10.190.109.104:63086/7.212.123.28:11000] ERROR: java.lang.ArrayIndexOutOfBoundsException

Hi @peilinqian, thank you for your feedback. Now, cursor only support simple select and order by statement, and not support group by statement.
