如何在JPA JPQL中编写此SQL select？

Question

我有一个表 ，称为REI_BODY ，另一个，有一个表 REI_AMT_INFO 。 我在oracle pl / sql中有一个选择：

选择 *，

  (SELECT AMT FROM REI_AMT_INFO I WHERE I.REI_ID=T.REI_ID AND AMT_TYPE_CD = '01') AMT_01, (SELECT AMT FROM REI_AMT_INFO I WHERE I.REI_ID=T.REI_ID AND AMT_TYPE_CD = '02') AMT_02, (SELECT SGN_CD FROM REI_AMT_INFO I WHERE I.REI_ID=T.REI_ID AND AMT_TYPE_CD = '01') SGN_01, (SELECT SGN_CD FROM REI_AMT_INFO I WHERE I.REI_ID=T.REI_ID AND AMT_TYPE_CD = '02') SGN_02, FROM REI_BODY T 

这是REI_AMT_INFO表， 没有外键！ ：

REI_ID (Number);
AMT_TYPE_CD (Varchar);
AMT (Number);
SGN_CD (Varchar);

我必须用JPA JPQL语言创建此选择。 我该怎么办？

@NamedQuery(
    name="REI_BODY",
    query="SELECT *,

  (SELECT AMT    FROM REI_AMT_INFO I WHERE I.REI_ID=T.REI_ID AND AMT_TYPE_CD = '01') AMT_01,
  (SELECT AMT    FROM REI_AMT_INFO I WHERE I.REI_ID=T.REI_ID AND AMT_TYPE_CD = '02') AMT_02,

  (SELECT SGN_CD FROM REI_AMT_INFO I WHERE I.REI_ID=T.REI_ID AND AMT_TYPE_CD = '01') SGN_01,
  (SELECT SGN_CD FROM REI_AMT_INFO I WHERE I.REI_ID=T.REI_ID AND AMT_TYPE_CD = '02') SGN_02,

FROM REI_BODY T"
)
