## 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, full_path=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.282.b08-1.el7_9.x86_64/bin/java ShardingSphere-5.2.1-SNAPSHOT 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 at org.opengauss.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2901) at org.opengauss.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:2630) at org.opengauss.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:362) at org.opengauss.jdbc.PgStatement.runQueryExecutor(PgStatement.java:562) at org.opengauss.jdbc.PgStatement.executeInternal(PgStatement.java:539) at org.opengauss.jdbc.PgStatement.execute(PgStatement.java:397) at org.opengauss.jdbc.PgStatement.executeWithFlags(PgStatement.java:339) at org.opengauss.jdbc.PgStatement.executeCachedSql(PgStatement.java:325) at org.opengauss.jdbc.PgStatement.executeWithFlags(PgStatement.java:302) at org.opengauss.jdbc.PgStatement.executeQuery(PgStatement.java:241) at cursor.CursorTest01.main(CursorTest01.java:32) ``` ### Reason analyze (If you can) ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
