### Reason analyze (If you can)
ShardingSphere-JDBC just does a union on the `exists` result of the sharding tables and returns two row
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
```
@Select("select exists(select * from t_order where order_name=#{orderName} limit 1) as c")
boolean existsOrderAsByOrderId(@Param("orderName") String orderName);
```
### Example codes for reproduce this issue (such as a github link).
