BULK INSERT and csv format, new in vNext 1.1

In SQL Server vNext 1.1 we now have the ability to import a csv via the BULK INSERT command without having to specify the field or row terminator

 You still need to specify the format, if you only do something like the following

BULK INSERT AlexaSongs  
   FROM 'c:\Songs played with Alexa.csv'  

You will be greeted with these errors


Msg 4832, Level 16, State 1, Line 10
Bulk load: An unexpected end of file was encountered in the data file.
Msg 7399, Level 16, State 1, Line 10
The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.
Msg 7330, Level 16, State 2, Line 10
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".

So let's take a look at how this all works

First create the following table

USE tempdb
GO

CREATE TABLE AlexaSongs(PlayDate varchar(100), 
   SongName varchar(200), 
   Artist varchar(200), 
   Album varchar(200))
GO

Now grab the csv file from here Songs played with Alexa.csv  Either download the whole project and grab the file, or open in raw mode and copy and paste it into a file and save as Songs played with Alexa.csv

Now that you have the file and table ready, let's first take a look at how this was done before vNext 1.1

Here is what it looked like

BULK INSERT AlexaSongs  
   FROM 'c:\Songs played with Alexa.csv'  
   WITH  
     (  
        FIELDTERMINATOR =',',  
        ROWTERMINATOR = '\n'
      ); 

As you can see, we specified a comma as the field terminator and a newline as the row terminator

You could also get it to work by just specifying the field terminator in this case

BULK INSERT AlexaSongs  
   FROM 'c:\Songs played with Alexa.csv'  
   WITH  
     (  
        FIELDTERMINATOR =','
      ); 

So what does the new syntax look like?

Here is the code that accomplished the same as above but by using the new WITH FORMAT = CSV option

BULK INSERT AlexaSongs
FROM 'c:\Songs played with Alexa.csv' 
WITH (FORMAT = 'CSV'); 

I guess you could say it is a little cleaner, but all this really is is syntactic sugar

For Azure, it looks like this, I grabbed this straight from this Books On Line Page here

First you need to create a data source

CREATE EXTERNAL DATA SOURCE MyAzureInvoices
    WITH  (
        TYPE = BLOB_STORAGE,
        LOCATION = 'https://newinvoices.blob.core.windows.net', 
        CREDENTIAL = UploadInvoices  
    );

And then you use that data source

BULK INSERT Colors2
FROM 'week3/inv-2017-01-19.csv'
WITH (DATA_SOURCE = 'MyAzureInvoices',
      FORMAT = 'CSV');

That's all for today
