Question

我正在尝试通过JPQL更新表列，我的其余查询看起来像下面这样。

http://localhost:6765/salesfactory/rest/v2/queries/sales$Applications/update?status=KILLED&appID=a896f3e5-9abc-a9a1-f14d-24c9eb22896a

        <jpql> <![CDATA[
                   UPDATE sales$Applications v
                   SET v.status = :status
                   WHERE v.id = :appID
                ]]>
        </jpql>
        <params>
            <param name="status" type="java.lang.String"/>
            <param name="appID" type="java.util.UUID"/>
        </params>

    </query>

我能够进行各种选择操作，但是当涉及到更新时，我无法做到，我认为这与我如何查询JPQL有关。我用谷歌搜索，但我找不到任何非常接近解决方案的东西。

另请注意，我正在使用cuba-platform and rest queries.下面的异常跟踪 - 希望它有用。

CUBA不支持通过rest v2 query api进行批量更新。您可以使用其他服务调用。请参阅相关文档：https://doc.cuba-platform.com/manual-6.5/rest_api_v2_services_config.html

如何修复eclipselink.refresh对于JPQL中的此类查询无效？
