   but program below is ok :
   ```
   List<Integer> existRiskPlaceTypeIds = jpaQueryFactory.select(qBaseRecord.riskPlaceTypeId)
                   .from(qBaseRecord)
                   .fetch();
   ```
   
   I think the reason is jpa convert selectDistinct to `select distinct` with some special info, sharding-jdbc cannot understand the convert result
