有没有办法在jpa中创建从sql查询到实体对象查询的查询

Question

我有一个如下所示的查询：

SELECT
  SUM (LIMIT_AMOUNT)
FROM
  (SELECT
    CTR_NO
    , REPORT_DATE
    , LIMIT_AMOUNT
    , ROW_NUMBER()
  OVER (PARTITION BY CTR_NO, REPORT_DATE ORDER BY REPORT_DATE) rn
  FROM LOD_CONTRACT
  WHERE
    br_cst_code='3432434'
  AND REPORT_DATE BETWEEN '20-FEB-15' AND '28-FEB-15') b
WHERE
  b.rn=1;

如何为JPA管理的实体构建SQL查询，如：

SELECT
  SUM (o.limit_amount)
FROM
  (SELECT
    o.ctr_no
    , o.rpt_dt
    , o.limit_amount
    , ROW_NUMBER()
  OVER (PARTITION BY o.ctr_no, o.rpt_dt ORDER BY o.rpt_dt) rn
  FROM LOD_CONTRACT o
  WHERE
    o.br_cst_code='3432434'
  AND o.rpt_dt BETWEEN '20-FEB-15' AND '28-FEB-15') b
WHERE
  b.rn=1;

Answer 1

JPQL当前不支持Oracle分区表。要使用此功能，您必须坚持使用本机查询。
