Box 1: openrowset

The easiest way to see to the content of your CSV file is to provide file URL to OPENROWSET function, specify csv FORMAT.

Example:

SELECT *

FROM OPENROWSET(

BULK ‘csv/population/population.csv’,

DATA_SOURCE = ‘SqlOnDemandDemo’,

FORMAT = ‘CSV’, PARSER_VERSION = ‘2.0’,

FIELDTERMINATOR =’,’,

ROWTERMINATOR = ‘n’

Box 2: openjson

You can access your JSON files from the Azure File Storage share by using the mapped drive, as shown in the following example:

SELECT book.* FROM

OPENROWSET(BULK N’t:booksbooks.json’, SINGLE_CLOB) AS json

CROSS APPLY OPENJSON(BulkColumn)

WITH( id nvarchar(100), name nvarchar(100), price float, pages_i int, author nvarchar(100)) AS book
