Question

我正在尝试计算一些信息，并希望使用构造函数通过namedquery将它们插入到我的数据库中这是代码：

@NamedQuery(name = PageEntity.FIND_ALL_PAGES_BY_TYPE, query = "SELECT DISTINCT new PageEntity
(e.id,e.backendId,e.name,e.pageType,e.updatedOn,e.updatedBy,e.mobileEnabled,e.desktopEnabled,e.mobileEnabledBy,e.desktopEnabledBy,e.mobileEnabledOn,e.desktopEnabledOn,
    (SELECT COUNT(sc) FROM SectionContentEntity sc, PageSectionEntity ps WHERE ps.section.archived = false AND ps.page = e AND ps.section = sc.section), 
    (SELECT COUNT(sc) FROM SectionContentEntity sc, PageSectionEntity ps WHERE ps.section.archived = false AND ps.page = e AND ps.section = sc.section AND sc.desktopEnabled = false AND sc.mobileEnabled = false),
    (SELECT COUNT(sc) FROM SectionContentEntity sc, PageSectionEntity ps WHERE ps.section.archived = false AND ps.page = e AND ps.section = sc.section AND sc.desktopEnabled = true),
    (SELECT COUNT(sc) FROM SectionContentEntity sc, PageSectionEntity ps WHERE ps.section.archived = false AND ps.page = e AND ps.section = sc.section AND sc.mobileEnabled = true), 
    (SELECT COUNT(ps) FROM PageSectionEntity ps WHERE ps.section.archived = false AND ps.page = e),
    (SELECT COUNT(ps) FROM PageSectionEntity ps WHERE ps.section.archived = false AND ps.page = e AND ps.mobileEnabled = true),
    (SELECT COUNT(ps) FROM PageSectionEntity ps WHERE ps.section.archived = false AND ps.page = e AND ps.desktopEnabled = true)
) FROM PageEntity e  WHERE e.archived=false AND e.removed=false AND e.pageType IN (:pageTypes) ORDER BY e.id"),

这是我得到的错误：

使用构造函数在一个查询中选择多个计数
