在 WHERE 子句中使用枚举的 FlexibleSearch

Question

我正在使用 Hybris 并尝试在 Java 代码中查询所有批准状态为 APPROVED 的产品。它应该如下所示，但我无法让它在 HAC 或 Java 代码中工作。

正确的做法是什么？

SELECT {p:pk} FROM {Product as p join EnumerationValue as enum on enum.pk = p.approvalStatus } WHERE {enum:code[en]} = 'APPROVED'

谢谢大家，这是有效的最终答案，请参阅其他回复中的评论以了解我的更多问题，并希望得到一些非常明智的回复：

        final StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("SELECT {p:").append(ProductModel.PK).append("} ");
        stringBuilder.append("FROM {").append(ProductModel._TYPECODE).append(" as p join ")
                .append(ArticleApprovalStatus._TYPECODE).append(" as enum on {enum.pk} = {p.").append(ProductModel.APPROVALSTATUS).append("} join ")
                .append(CatalogVersionModel._TYPECODE).append(" as cv on {cv.pk} = {p.").append(ProductModel.CATALOGVERSION).append("} } ");
        stringBuilder.append("WHERE ( {enum:code} = ?approvalStatus1 or {enum:code} = ?approvalStatus2} and {cv:")
                .append(CatalogVersionModel.VERSION)
                .append("} = ?version");

        final String unapprovedString = ArticleApprovalStatus.UNAPPROVED.toString().toLowerCase();
        params.put("approvalStatus1", unapprovedString);
        params.put("approvalStatus2", ArticleApprovalStatus.UNAPPROVED.toString().toLowerCase());

Answer 1

您需要使用枚举的类型。此外，枚举代码区分大小写；这取决于 items.xml.

中定义的内容

SELECT * FROM {Product 
JOIN ArticleApprovalStatus ON {Product.approvalStatus} = {ArticleApprovalStatus.pk}}
WHERE {ArticleApprovalStatus.code} = 'approved'

Answer 2

尝试像这样用 {} 包裹属性：

SELECT {p:pk} FROM {Product as p join EnumerationValue as enum on {enum.pk} = {p.approvalStatus} } WHERE {enum:code[en]} = 'APPROVED'

在 WHERE 子句中使用枚举的 FlexibleSearch

FlexibleSearch using enum in WHERE clause
