Question

我想在SQL Server 2016表中插入一些JSON对象。

我的表格结构如下：

field           type            nullable   default
name          | nvarchar(max) | true     | Null
age           | nvarchar(max) | true     | Null
homeAddress   | nvarchar(max) | true     | Null
officeAddress | nvarchar(max) | true     | Null

我使用以下查询来插入我的数据：

DECLARE @json NVARCHAR(MAX) = N'{"name":"John Smith","age":32,"homeAddress":{"addr1":"123rd West Street, Willow Apt","addr2":"#55 Suite","zipCode":12345,"city":"Austin","state":"TX"},"officeAddress":{"addr1":"23rd West Street","addr2":"","zipCode":12345,"city":"Austin","state":"TX"}}';

INSERT INTO Employee 
    SELECT * 
    FROM OPENJSON(@json)
    WITH (name nvarchar(50), 
          age int, 
          homeAddress nvarchar(max), 
          officeAddress nvarchar(max)
         );

但是，表格中仅填充name和age的值。 homeAddress和officeAddress值均为NULL。

我的查询有什么问题？如何将JSON对象作为nvarchar插入？

我承认我在SQL Server 2016中没有使用JSON的经验，但是看看本教程：

https://docs.microsoft.com/en-us/sql/relational-databases/json/solve-common-issues-with-json-in-sql-server

在AS JSON列之后添加NVARCHAR(max)似乎是您需要的：

INSERT INTO Employee 
    SELECT * 
    FROM OPENJSON(@json)
    WITH (name nvarchar(50), 
          age int, 
          homeAddress nvarchar(max) AS JSON, 
          officeAddress nvarchar(max) AS JSON
         );
