[GitHub] [shardingsphere] vther opened a new issue #6332: JPA [count distinct] cause [javax.persistence.NoResultException: No entity found for query]
vther opened a new issue #6332:
URL: https://github.com/apache/shardingsphere/issues/6332
## Bug Report
```java
Object singleResult = entityManager
.createQuery("SELECT count (distinct i.orderItemId) from OrderItemEntity i where i.orderId = :orderId")
.setParameter("orderId", 11111111111111111L)
.getSingleResult();
```
when use `count distinct` and `entitymanager#getSingleResult()` cause javax.persistence.NoResultException
### Which version of ShardingSphere did you use?
[4.0.1 , 4.1.1] the bug remains
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
### Actual behavior
### Reason analyze (If you can)
Actual SQL lack of count ，is it intentional or a bug？
```

```
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
.setParameter("orderId", 11111111111111111L)
this step is necessary
### Example codes for reproduce this issue (such as a github link).
