Importar datos a SQL Server

Declare @JSON varchar(max)

SELECT @JSON=BulkColumn
FROM OPENROWSET (BULK '/home/user/Downloads/data.json', SINGLE_CLOB) import

SELECT *
FROM OPENJSON (@JSON)
WITH 
(
    [code] nvarchar(2), 
    [name] nvarchar(50),
      [locations] nvarchar(50),
      [firstUpdated] datetime2,
      [lastUpdated] datetime2,
      [parameters] nvarchar(max),
      [count] bigint,
      [cities] bigint,
      [sources] bigint
)
