为什么json_value返回null？

标签： sql json sql-server

我注意到JSON_VALUE函数的异常行为，有时即使返回的值几乎与数据集相同也返回null。这是一个示例：

null value 

select JSON_VALUE([value],'$.result_serialized_data') as value,  value as orig 
from #tempFromFile

有效时我从中提取json_value的数据：

我在做什么错了？

2 个答案:

答案 0 :(得分：1)

如documentation中所述，如果该值大于4000个字符，则JSON_VALUE（）在宽松模式下返回null，在严格模式下返回错误。您需要改用OPENJSON()（具有默认或显式架构），因为第二个JSON字符串中的result_serialized_data键的值大于4000个字符。

声明：

SELECT [value]
FROM OPENJSON(@json,'$')
WHERE [key] = 'result_serialized_data'

-- or

SELECT *
FROM OPENJSON(@json,'$') WITH (
   result_serialized_data nvarchar(max) '$.result_serialized_data'
)

答案 1 :(得分：1)

看起来您的值大于4000个字符，这就是JSON_VALUE为空的原因。

MSDN表示值是否大于4000个字符：

  • 在宽松模式下，JSON_VALUE返回null。

  • 在严格模式下，JSON_VALUE返回错误。

为此尝试OPENJSON 

SELECT j.[value] AS value, 
       t.value   AS orig 
FROM   #tempfromfile t 
       CROSS apply OPENJSON(t.value) j 
WHERE  j.[key] = 'result_serialized_data'
