[GitHub] [shardingsphere] ben905713861 opened a new issue #8978: SeataAT transaction in ShardingSphere-Proxy block abnormally
ben905713861 opened a new issue #8978:
URL: https://github.com/apache/shardingsphere/issues/8978
## Bug Report
### Which version of ShardingSphere did you use?
4.1.1
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
When I use Seata-AT transaction in ShardingSphere-Proxy,I have start transaction and send a `select for update` SQL,the ShardingSphere-Proxy is blocking forever.
（使用Seata-AT事务，执行select for update语句会永久阻塞）
```sql
BEGIN;
SELECT * FROM user WHERE id=1 FOR UPDATE;
```
After sending this SQL,ShardingSphere-Proxy is blocking.
In this test, I use wireshark to analysis, I can see the SQL send to ShardingSphere-Proxy and MySQL-Server successfuly, and MySQL-Server echo the result successfuly.
（抓包分析，mysql服务收到了分片语句并成功返回）
### Another behavior
Using `insert`, `update` or `delete` SQL is successful, only the `select for update` is failed (Blocking forever)
（使用增删改是正常的，只有select for update语句是永久阻塞）
