[英]Generate JSON from SQL Server
I need to generate JSON string from a sql table (using the FOR JSON AUTO
qualifiers), while one (or more) of the columns is (are) stored as json string. 我需要从sql表(使用
FOR JSON AUTO
限定符)生成JSON字符串,而其中一列(或多列)存储为json字符串。
eg: 例如:
Table Persons: 表人员:
First_Name | Family_Name |City | Children
--------------+---------------+----------+---------------
David |Bin | Miami |[{"First_Name" :"John","Family_Name":"Bin"}]
Mary |Nis | New York |[]
The required result would then be: 所需的结果将是:
[
{"First_Name":"David",
"Family_Name":"Bin",
"City":"Miami",
"Children": [{"First_Name" :"John",
"Family_Name":"Bin"}
]
},
{"First_Name":"Mary",
"Family_Name":"Nis",
"City":"New York",
"Children": []
}
]
My current issue is that in the result, all the occurrences of the "
are escaped and hence the application receiving it fails (illegal JSON). 我当前的问题是,结果中所有出现的
"
都将转义,因此接收它的应用程序将失败(非法JSON)。
Could anyone suggest the correct phrasing for the SELECT
command that would generate the result shown above? 谁能为
SELECT
命令提供正确的措词,以产生上面显示的结果?
Thanks in advance. 提前致谢。
Try this: 尝试这个:
SELECT First_Name ,
Family_Name ,
City ,
JSON_QUERY(Children)
FROM Person FOR JSON AUTO ;
