Question

我想将JSON文件的数据保存在SQL表的本地路径中。

存在JSON文件的我的本地路径为E：\ 20180824LocalDump.json

我已经在SQL中使用以下代码从JSON文件中获取数据，但出现错误。

DECLARE @Details VARCHAR(MAX)  
SELECT @Details = BulkColumn FROM OPENROWSET(BULK 'E:\20180824LocalDump.json', SINGLE_BLOB) JSON;   
SELECT * FROM OPENJSON(@Details)   
WITH(Departure_airport nvarchar(50)  ,
    DisplayName nvarchar(40), 
    Email nvarchar(60),
    Keep_me_deals nvarchar(40),
    Phone_Code nvarchar(50),
    Provider nvarchar(50),
    SignUpDate nvarchar(50),
    Telephone nvarchar(50),
    [Platform] nvarchar(50),
    AppVersion nvarchar(40))

创建了一个表格，如下所示：

Create Table Dump
(
Departure_airport nvarchar(50),
DisplayName nvarchar(40),
Email nvarchar(60),
Keep_me_deals nvarchar(40),
Phone_Code nvarchar(50),
Provider nvarchar(50),
SignUpDate nvarchar(50),
Telephone nvarchar(50),
[Platform] nvarchar(50),
AppVersion nvarchar(40)
)

我的Json文件内容：

[{"Departure_airport":"Test","DisplayName":"Test","Email":"Tst","Keep_me_deals":"Test","Phone_Code":"Test","Provider":"Test","SignUpDate":"Test","Telephone":"Test","Platform":"Test","AppVersion":"Test"},{"Departure_airport":"Test","DisplayName":"Test","Email":"Tst","Keep_me_deals":"Test","Phone_Code":"Test","Provider":"Test","SignUpDate":"Test","Telephone":"Test","Platform":"Test","AppVersion":"Test"},{"Departure_airport":"Test for IE","DisplayName":"Test for IE","Email":"Tst for IE","Keep_me_deals":"Test for IE","Phone_Code":"Test for IE","Provider":"Test for IE","SignUpDate":"Test for IE","Telephone":"Test for IE","Platform":"Test for IE","AppVersion":"Test for IE"},{"Departure_airport":"Test for UK","DisplayName":"Test for UK","Email":"Tst for UK","Keep_me_deals":"Test for UK","Phone_Code":"Test for UK","Provider":"Test for UK","SignUpDate":"Test for UK","Telephone":"Test for UK","Platform":"Test for UK","AppVersion":"Test for UK"},{"Departure_airport":"Test for UK 1","DisplayName":"Test for UK 1","Email":"Tst for UK 1","Keep_me_deals":"Test for UK 1","Phone_Code":"Test for UK 1","Provider":"Test for UK 1","SignUpDate":"Test for UK 1","Telephone":"Test for UK 1","Platform":"Test for UK 1","AppVersion":"Test for UK 1"}]

我遇到类似以下错误：

SQL中无效的对象名称'OPENJSON'。

请帮助我

Answer 1

如果您使用的是SQL 2016或更高版本，则还应该检查运行查询的数据库的兼容性级别。

main

如果它不是至少130，则需要（在您的DBA的许可下）更改它。

USE <your database>;  
GO  
SELECT compatibility_level FROM sys.databases WHERE name = '<your database>';  
GO

您可能想让Google获得更改兼容性级别的其他效果，但这从来没有给我造成任何问题。

不幸的是，您不能在SQL Server 2014中使用openjson：SQL Server 2016引入了本机json函数（有关openjson here的更多信息）。

链接页面的摘录：

适用于：服务器（从2016年开始）

您仍然可以使用OPENROWSET导入json文件，但是您将不得不依靠字符串操作函数或自定义函数从json文件中提取数据。

如何将JSON文件的数据保存到SQL表的本地路径中？
