为什么 SQL returns 是数组而不是对象?
Why SQL returns an Array instead of an Object?
我正在使用 SQL SERVER 2016 JSON 结果,但我不知道为什么它将所有内容都转换为数组,例如如果我执行以下查询,它 return 是一个数组而不是对象:
SELECT 1 AS One,2 AS Two,3 AS Three
FOR JSON PATH
结果是:
[{"One":1,"Two":2,"Three":3}]
但我想 return:
{"One":1,"Two":2,"Three":3}
我也测试了这个查询,但结果是一样的,还是一个数组:
SELECT TOP 1 1 AS One,2 AS Two,3 AS Three
FOR JSON PATH
您只需要 WITHOUT_ARRAY_WRAPPER
选项:
SELECT 1 AS One,2 AS Two,3 AS Three
FOR JSON PATH ,WITHOUT_ARRAY_WRAPPER;
