Openrowset from CSV file - sql-server

Question

I am trying to read from a CSV file located on shared folder on the network but getting error for the following code:
SELECT * INTO #TempTbl
FROM OPENROWSET
('SQLNCLI11',
'ServerName = <username>;Trusted_Connection=yes;',
'Driver={Microsoft Text Driver (*.txt; *.csv)};
DefaultDir=\\sharedpath\DIR path\;
SELECT * FROM CSV_File.csv) as Test
Msg 102, Level 15, State 1, Line 4
Incorrect syntax near ','.
When I remove the server line like this:
SELECT * INTO #TempTbl
FROM OPENROWSET
('SQLNCLI11',
--'ServerName = <username>';Trusted_Connection=yes;',
'Driver={Microsoft Text Driver (*.txt; *.csv)};
DefaultDir=\\sharedpath\DIR path\;
SELECT * FROM CSV_File.csv) as Test
I get the following error:
OLE DB provider "SQLNCLI11" for linked server "(null)" returned message "Invalid authorization specification".
OLE DB provider "SQLNCLI11" for linked server "(null)" returned message "Invalid connection string attribute".
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "SQLNCLI11" for linked server "(null)" reported an error. Authentication failed.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "SQLNCLI11" for linked server "(null)".
What does that mean? Does this error message indicate something wrong in my script or is access permission issue? I was able to read from a table on the server suing the same openrowset connection when I no longer use the CSV driver.
I am not sure what to do in order to get this openrowset to read the CSV file. Any clue? Do you think it has to do with the server account does not have access to the account I am using does not have access to the shared folder?

Answer 1

You are using the wrong provider. Your connection string is written for connecting to a server (sort of). You should be using the bulk option for OPENROWSET per example E on this page.
It would look something like this, although you need to create a format file per the instructions here.
SELECT *
FROM OPENROWSET( BULK '\\sharedpath\DIR path\CSV_File.csv',
FORMATFILE = '\\sharedpath\DIR path\CSV_format.fmt');
