How-To Synchronize data Between Excel 2007 and SQL Server 2008 | OPENDATASOURCE

Opendatasource provides the means to create adhoc connections. It uses a linked server object. You can access server locally or remotely. You can add the same kind of parameters as a linked server object including username and password. If you need to access a remote server using an ole db provider such as the “Microsoft.ACE.OLEDB.12.0” you need to set the registry option “DisallowAdhocAcces “ to 0 and of course the Ad hoc Distributed Queries needs to be enabled which is the case many of these examples like OPENROWSET and Linked Server Objects.

Below are a series of examples to demonstrate the OPENDATASOURCE function to insert, update, select and delete data in Excel from SQL Server. They are simple examples to get you going. But I have found that even the more complex situations still use the basic syntax.

I struggled a good while with the syntax. I admit I have scoured the forums looking for an answer to the question:

Msg 7399, Level 16, State 1, Line 2

The OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)" reported an error. The provider did not give any information about the error.

Msg 7303, Level 16, State 1, Line 2

Cannot initialize the data source object of OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)".


What we need to understand about the “Microsoft.ACE.OLEDB.12.0” is that it is primarily made to connect to an Access 2007 database. Also with Office 2007 we are dealing with Xml type of documents.

First to solve this equation I decided to change the “Data source” keyword to “Database” like this : Database=C:\temp\music.xlsx. Next Excel has two file types, xlsx and xlsm. The first is a macro free file, pure xml, othe other is a macro enable file. Knowing this it is important to specify that the database is Excel. You specify this with the Extended Properties clause and specifying that we are dealing eithe an XML or Macro file type. This is the syntax: “Extended Properties="Excel 12.0 Xml;”. So when working with OPENDATASOURCE you need to use this init string:


'Microsoft.ACE.OLEDB.12.0','Excel 12.0;Database=C:\temp\music.xlsx; Extended Properties="Excel 12.0 Xml;HDR=YES";',



One other tidbit of information is that it seems that when I tried using variables like

Declare @serviceprovider nvarchar(500)
Declare @initString nvarchar(2000)

SET @serviceprovider='Microsoft.ACE.OLEDB.12.0'
SET @initString='Excel 12.0;Database=C:\temp\music.xlsx;Extended Properties="Excel 12.0; Xml;HDR=YES";'

INSERT INTO OPENDATASOURCE(@serviceprovider, @initString)...[music$]

You will get the following error message: Msg 102, Level 15, State 1, Line 8
Incorrect syntax near '@serviceprovider'.

The workaround is to use the literal string when specific the Service Provider and initializing string.

Here are the examples:

Insert


SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author: <Author,,Name>
-- Create date: <Create Date,,>
-- Description: <Description,,>
-- =============================================
CREATE PROCEDURE dbo.InsertIntoExcelUsingOPENDATASOURCE

AS
BEGIN

INSERT INTO OPENDATASOURCE('Microsoft.ACE.OLEDB.12.0','Excel 12.0;Database=C:\temp\music.xlsx; Extended Properties="Excel 12.0 Xml;HDR=YES";')...[music$]
SELECT * FROM dbo.Music

END
GO

Select


SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE dbo.SelectExcelUsingOPENDATASOURCE

AS
BEGIN

SELECT * FROM  OPENDATASOURCE ('Microsoft.ACE.OLEDB.12.0','Excel 12.0;Database=C:\temp\music.xlsx;Extended Properties="Excel 12.0; Xml;HDR=YES";')...[music$]

END
GO

Update


SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE dbo.UpdateExcelUsingOPENDATASOURCE

AS
BEGIN
UPDATE OPENDATASOURCE ('Microsoft.ACE.OLEDB.12.0',
'Excel 12.0;Database=C:\temp\music.xlsx;
Extended Properties="Excel 12.0; XmlHDR=YES";')...[music$]

SET [Song Title]='Miracles', Artist='Jefferson Starship',[Release Date]='1975', Album='Red Octopus', Decade='70'


END
GO

Delete



SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE dbo.DeleteExcelUsingOPENDATASOURCE

AS
BEGIN
DELETE FROM OPENDATASOURCE ('Microsoft.ACE.OLEDB.12.0',
'Excel 12.0;Database=C:\temp\music.xlsx;
Extended Properties="Excel 12.0; XmlHDR=YES";')...[music$]

WHERE  [Song Title]='Miracles'

END
GO

Yes make sure your Excel file is closed before executing sproc.

Also under sql server service in windows, make sure user has read /write access to folder and excel file
