Question

如何在下面编写SQL查询，以提及使用FOR JSON的表结构和JSON输出。

表结构

CREATE TABLE [dbo].[TreeView](
[AuditId] [int] NOT NULL,
[Id] [int] NOT NULL,
[FatherId] [int] NULL,
[MotherId] [int] NULL,
[EnglishName] [varchar](500) NULL,
[Description] [nchar](10) NULL,
[Image] [varchar](500) NULL,

JSON输出

 { id: 1, title: "Meera Mohaideen", description: "", image: "demo/images/photos/m.png" },
            { id: 2, title: "Rahman Beevi", description: "", image: "demo/images/photos/f.png" },
            { id: 3, title: "Abdul Jabbar", description: "", image: "demo/images/photos/m.png" },
            { id: 4, title: "Jahabar Natchiyal", description: "", image: "demo/images/photos/f.png" },
            { id: 5, parents: [1,2] ,title: "AJhir Ali", description: "", image: "demo/images/photos/m.png" },
          { id: 6, parents: [3, 4], title: "Kamila Begam", description: "", image: "demo/images/photos/f.png" },
           { id: 7, parents: [5, 6], title: "Simra", description: "7", image: "demo/images/photos/f.png" }

查询

SELECT Id AS Id, 
CASE WHEN ISNULL(FatherId,0) <> 0 OR ISNULL(MotherId,0) <> 0 THEN 
CAST(FatherId AS VARCHAR(25)) + ',' + CAST(MotherId AS VARCHAR(25)) END AS parents, 
EnglishName AS title, 
[Description] AS Description, 
[Image] AS Image FROM TreeView 
FOR JSON AUTO

我尝试过，但结果是{“ Id”：5，“父母”：“ 1,2”，“标题”：“ AJhir Ali”} 但我期望这个{“ Id”：5，“父母”：[1,2]，“标题”：“ AJhir Ali”}

谢谢
