我正在使用AZURE SQL(SQL Server 2016)并创建一个查询来为我提供JSON对象的输出.我FOR JSON PATH在查询结束时添加.

当我执行该过程而不添加FOR JSON PATH查询时,我得到244行(我的表中没有记录); 但是当我通过添加FOR JSON PATH我获取消息33行来执行该过程时,我也得到了被截断的JSON对象.

我使用不同类型的查询测试了这一点,包括只选择10列的简单查询,但我总是得到更少的行数,FOR JSON PATH并且最后截断了JSON对象.

这是我的查询

SELECT 
    [Id]
    ,[countryCode]
    ,[CountryName]
    ,[FIPS]
    ,[ISO1]
    ,[ISO2]
    ,[ISONo]
    ,[capital]
    ,[region]
    ,[currency]
    ,[currencyCode]
    ,[population]
    ,[timeZone]
    ,[timeZoneCode]
    ,[ISDCode]
    ,[currencySymbol]
FROM 
    [dbo].[countryDB]

上面的查询返回2行.

我使用以下查询来获取JSON中的输出

SELECT 
    [Id]
    ,[countryCode]
    ,[CountryName]
    ,[FIPS]
    ,[ISO1]
    ,[ISO2]
    ,[ISONo]
    ,[capital]
    ,[region]
    ,[currency]
    ,[currencyCode]
    ,[population]
    ,[timeZone]
    ,[timeZoneCode]
    ,[ISDCode]
    ,[currencySymbol]
FROM 
    [dbo].[countryDB] 
FOR JSON PATH

上面的查询返回33行,输出为
