使用vb.net将JSON文件导入SQL Server数据库

Question

I want to import a big JSON file with this structure:

{
  "series_id":"NG.RL2R04SOK_1.A",
  "name":"Oklahoma Natural Gas Plant Liquids, Reserves Revision Decreases, Annual",
  "units":"Million Barrels",
  "f":"A",
  "unitsshort":"MMbbl",
  "description":"Oklahoma Natural Gas Plant Liquids, Reserves Revision Decreases",
  "copyright":"None","source":"EIA, U.S. Energy Information Administration",
  "iso3166":"USA-OK",
  "start":"1979",
  "end":"2008",
  "last_updated":"13-AUG-13 11.49.51 AM",
  "data":[
     ["2008","136"],
     ["2007","73"],
     ... 
     ["1980","69"],
     ["1979","54"]
  ]
}

into a SQL Server database.

Usually I use VB.net to import CSV/TXT/Excel into this database, but I have no knowledge of JSON.

Is there a simple way to do that ?

Thanks a lot

In SQL Server 2016 you can open (and import) json files directly using TSQL:

SELECT import.*
FROM OPENROWSET (BULK 'f:\import.json', SINGLE_CLOB) as j
CROSS APPLY OPENJSON(BulkColumn)
WITH( 
    [series_id]    nvarchar(100), 
    [name]         nvarchar(100),
    [units]        nvarchar(100),
    [f]            nvarchar(100),
    [unitsshort]   nvarchar(100),
    [description]  nvarchar(100),
    [copyright]    nvarchar(100),
    [iso3166]      nvarchar(100),
    [start]        int,
    [end]          int,
    [last_updated] nvarchar(100),
    [data]         nvarchar(100) 
) AS import

This query returns a table containing data read from json file and organized with the columns specified in the WITH clause.
