Create a linked server to connect ot an Access Database.

I would like to link an Access database into SQl Server.  I think I can do this using a linked server.  And I need and ODCB data source for the Access database.  Can anyone help me with this?

If you remove any of the inside elements from the complete 4 way qualification you will have the empty string between the dots. So the following are equivalent given the fact there are no ambiguities:

select * from server_name.db_name.owner.table

remove owner:
select * from server_name.db_name..table

remove database as well:
select * from server_name...table

hence the 3 dots.

ZberteocCommented:
In that image it says that you are trying to connect to an SQL server. Weren't you trying to connect to Access?

I want to connect to Access.  I have create a ODBC system Data Source called "Gravity".  What am I doing wrong?

Use the Jet  Engine drive as in the video.

Zberteoc - are you saying to use the JET engine in the ODBC datasource?

ZberteocCommented:
Yes.

HLRosenbergerAuthor Commented:
ah, I see what you mean.  I'll give that a shot.  Currently, I have Office 2010 32 bit, and I can't install the JET engine download.

Isn't it there already? It comes with Access and Excel, usually.

HLRosenbergerAuthor Commented:
no, it' not in my list.   I'm using SQL 2008, which is 64 bit?  I was thinking that only 64-bit providers would be shown?   I tried to install the 64-bit version of the Access Database engine, but I can't - it tell me that I have to uninstall the 32-bit Office stuff first.

Install this:

https://www.microsoft.com/en-us/download/details.aspx?id=13255

And then you can do this:
EXEC sp_addlinkedserver
   @server = 'Test'
  ,@provider = 'Microsoft.ACE.OLEDB.12.0'
  ,@datasrc = '\\srv\public$\path_hete\YourAccess.mdb'
  ,@srvproduct='Access'
GO 

Open in new window

I did install that.  But I do not see JET 4.0 listed as a provider on the Create Linked Server screen.

I'll give that a shot.

I used your SQL.  However, when I try to open a table using Studio Manager, I get this error below.   Is 'Microsoft.ACE.OLEDB.12.0' 64 bit?  What would I use for 32-bit?  Can 64 SQL server use the 32 bit access drivers?

That has to be installed on the same computer where the SQL server is. Also maybe a restart could help.

ah, that got me further.  Now I get authentication error.

authentication error.

Try adding the default Admin user:
EXEC sp_addlinkedserver
   @server = 'Test'
  ,@provider = 'Microsoft.ACE.OLEDB.12.0'
  ,@datasrc = '\\srv\public$\path_here\YourAccess.mdb'
  ,@srvproduct='Access'
  ,@rmtuser='Admin'
GO 

Open in new window

Of course you would have to use the real names.

I got it working.  I had to put the MDB in a folder on the SQL server,.  Then I selected "Be made without a security context" for Authentication.    

Now, how do I issue SQL command against those tables?

If the liniked server was created successfully then you should be able to see it in the Server Objects > Linked Server node in the Object Bowser in the Management Studio. Make sure you refresh that first. One way is to expand that node and then the linked server you have created > Catalogs > Database name and then you will be able to see all the tables there. Right click on any table > Select top 1000...

For a linked server object you have to use a full reference:

select * from linked_server.database.owner.table

You will see in the first method how it is refereed to. The main idea is that you can use them the same way you would use any SQL database object(table/view). You can select, join, update insert and delete as long as you use the proper name.

ah, I got it to work! like this:

SELECT * FROM OPENQUERY(gravity , 'select * from cal_agreement')

UPDATE OPENQUERY(gravity, 'select * from cal_agreement where id = 7')  SET frequency_months = 9999

HLRosenbergerAuthor Commented:
in Management Studio, I cannot right click on the table to get records, like with a SQL table.  

Now, next question - How does one connect to the database in code?  Is there a connection string involved?

ZberteocCommented:
Again. you have to remember this concept: objects on a linked server that your SQL server login has access to can be referred to and access like any other objects in any SQL database your login has access to. So let's say that on your SQL server you have 2 database, called DB_1 and DB_2 and you also have the Access linked server named ACC.

Then a you could do this:

select 
    *
from
    DB_1.dbo.some_tble_on_DBA_1 t1
    inner join DB_2.dbo.some_tble_on_DBA_2 t2
	   on t2.col=t2.col
    inner join ACC.AccessDatabaseName..some_tble_on_AccessDatabase a
	   on a.col=t1.col

Open in new window

Maind you the two dots, are not a typo, that is what you are supposed to do. They mean "whatever owner"(default)

Isn't it three dots, not two?
