Accessing SAS/UNIX files using MS ACCESS

Hello, I am a SAS novice and learning SAS on my own. Here is what I'm trying to do:

 

I have SAS installed on UNIX. I use MS ACCESS to produce GUI based reports. I have few large files in SAS/UNIX. Is it possible to run query in SAS/UNIX files and produce report in MS ACCESS? I don’t want to import huge files from SAS/UNIX to MS ACCESS.

Re: Accessing SAS/UNIX files using MS ACCESS

If you have a SAS/SHARE server set up, you can use the SAS ODBC driver:

 

http://support.sas.com/software/products/odbc/

 

If you have SAS Integration Technologies (for use with SAS Enterprise Guide, for example), you can use the SAS IOM OLE DB provider.  You'll have to specify a connection string that includes your SAS Workspace host, port, and credentials.

 

Be sure to apply proper filters when you access (SQL or WHERE clause) so that you don't pull that huge data into your MS Access session.

Is it possible to run query against SAS files stored on UNIX without importing files to MS Access?

Re: Accessing SAS/UNIX files using MS ACCESS

One approach might be to do all of your big volume data processing in SAS, producing summary SAS tables that you then export to Access. If you have SAS/ACCESS Interface to PC Files you can export to MS Access instead of importing from it.

Re: Accessing SAS/UNIX files using MS ACCESS

You should be able to do this with the IML interface to R

You will need a prebult access database to write into.
Microsoft changes the structure of access so R works better
if you supply the access database.

You can find a sample access databases at
C:\Program Files\sashome\SASFoundation\9.4\access\sasmisc


* I have 64bit SAS 9.4M2 on Windows and 64 bit Office
* there are options for all combinations of 32 and 64bit R or/and Office
* Should work almost everywhere (Windows/Unicies/Mac OS but not Z/OS or VMS)

Re: Accessing SAS/UNIX files using MS ACCESS

You can apply a filter as a query on the "command" you send via OLE DB.  This SAS Note has some VB Script examples.  These might be overkill for what you're looking for.

 

It sounds like you need to access SAS as a database via MS Access.  ODBC and OLE DB are standard approaches from MS Access, if you have a running SAS instance (like SAS/Share or a SAS Workspace) that you can connect to.
