执行 hql 查询时出错

Question

在 hql 查询下方执行此操作时出现错误。 以下是 hql 中的查询及其生成的错误消息。 请提出更改建议

这是错误，它的显示，可能缺少某些东西。

unexpected token: ( near line 1, column 16 [SELECT c  FROM (select DISTINCT b FROM (select a.gcsAccountId, a.msisdn, a.partnerCode as bankID,0 as processingStatus from ( select min(additionDate) fechaAfilia, a.gcsAccountId, a.partnerCode, a.msisdn from

这是更改后的查询。

Answer 1

SELECT c  FROM (select DISTINCT b FROM (select ...

好吧，您正在从返回distinct b的子查询中选择c 。 那行不通。
