Subject: Summary of my post: PC SAS --> MS Access Date: Thu, 29 Aug 1996 17:57:00 -0400 From: "Hu, Raymond" <rch@S-3.COM> Newsgroups: comp.soft.sas Dear SAS-Lers: Many thanks to all of the people who responded to my question. The following is a summarization of the answers received and what I plan to do: Question: >Dear SAS-Lers: > I want to send data from a SAS session to a MS Access table during the >run-time. "During the run-time" is important to me because in this way I >can keep everything in one SAS program and the program can be run 100 times. > I checked the SAS Companion for the Microsoft Windows Environment, SAS >technical support doc TS 325, and talked to SAS Institute consultant, the >answer is no since SAS cannot send data to MS Access by DDE. > The only hope is that pre-coding some Access codes in MS Access, which >can read a ascii file, then sending a system command from SAS to MS Access Suggestions: 1. Buy SAS/ACCESS and use ODBC interface to MS Access (by Karsten Self, Amy Miceli, Darryl Hunter). 2. Buy DBMSCopy (www.conceptual.com) and translate SAS datasets to MS Access (by Karsten Self). 3. Output a delimited (column or comma, preferred) file and import to Access (by Karsten Self). 4. Buy DBMS/Engines and then read and write MS Access table directly. Option #4 is what I am planning to use right now. The following are my reasons for selecting DBMS/Engines: a) DBMS/Engines and SAS/Access can almost do the same thing. b) DBMS/Engines is easy to use not only with MS Access but also with other formatted files. So far I have used this software to read Paradox, MS Access, Excel 5, Quattro Pro for DOS, FoxPro(dBaseIII), and SPSS data files successfully. However, I am having some problems reading Quattro Pro for Windows and am working on that right now. For example, I am trying to use a Paradox table, equip.db: libname mypara dbpdox 'c:\data'; proc print data=mypara.equip (obs=20); run; c) DBMS/Engines is a one-time cost of $295, unlike the SAS annual fee. d) I didn't opt for #2 or #3 because they are short-term, one-time solutions, and I need to send data from SAS to a MS Access database throughout the year. Efficiency and fewer steps are preferable. Thank you again for your responses. SAS-L is a great place to learn and to find the best solutions.

I know how to do this with DDE. The difficult bit was iscovering all the bits for the DDE triplet and for the infile options eg
FILENAME ddedat2 DDE "msACCESS|DATAMODEL;query ENTITY-ATTR!ALL";
to read query ENTITY-ATTR from database DATAMODEL or
FILENAME ddedat2 DDE "msACCESS|DATAMODEL;table ENTITY!ALL";
to read the table ENTITY
That does the trick of reading the column headers.
Instead of OBS=1 use firstOBS=2 to read the data.
So, with DDE phasing out perhaps, what are the corresponding methods to infile through OLE.
Surely it won't be necessary to buy the SAS/access product ?
If the transfer from MS-Access to the SAS System is specific (the MS-Access
table/query is known and its columns informats known) you can use the windows
dde access to support the transfer.
I can't remember where I captured the following example.
When you use the infile dde method, you will need source database open in MS-Access.
It has been said that you can't use this (dde) method to go the opposite
direction ( out of the SAS System into MS-Access ) with a datastep.

/*** DDE--Example using Microsoft Access ***/
/* MS Access cannot have a '.' or missing value for numerics.
Have the user enter a number that could be out of range such as -99 or 0 for missing values then do a if-then to convert it to '.' Must use a firstobs=2 to bypass the column names on the MS Access data that is being read in clipboard. You must select the datatable from the TABLE window then do a 'Edit' 'copy'. You cannot do it from the datatable itself by hightlighting certain rows and cols. It's all or nothing. This is the only way the DDE triplet can be seen.

if weight=0 then weight =.;
if height=0 then height =.;

Although I have never used it myself, I was under the understanding that DBMS Copy could handle Access *.mdb's without any trouble, so perhaps you do just need an upgrade. There are, however, two other solutions that I have used that work very nicely: DDE and ODBC. I'm not sure how familiar you are with either, so I will attempt a brief but useful description of how to get Access data to SAS via ODBC and feel free to ask question if you need more information. Although the solution seems fairly straightforward to me now, there was some frustration along the way.
I) You have to set up an ODBC data source using the ODBC administrator. I usually use a "System DSN" for this (the other options are to set up "User" or "File" DSNs).
1) From the ODBC administrator (in the Control Panel on a Win '95/NT machine), click on the "System DSN" tab.
2) Click the "Add" button.
3) Choose the driver: in this case "MS Access."
4) Specify a name for the Data Source--I'll use "Test" in this example (this is what you'll use to identify the data from within SAS).
5) Click the "Select" button and specify the *.mdb file you want to access from SAS.
6) Click "OK" and you're done with step "I".
II) Get the data from within SAS using PROC SQL.
Here is some sample code that will return all the data from the table "tblTest" in the database specified by the "Test" DSN set up above:
PROC SQL NOPRINT;
CONNECT TO ODBC AS cnctn (DSN="Test" UID=admin);
CREATE TABLE work.sastable AS
FROM CONNECTION TO cnctn
DISCONNECT FROM cnctn;
1) You can see where the Data Source Name (DSN) was important in the CONNECT statement.
2) The (SELECT * FROM tblTest) is a valid Access SQL statement and could certainly be more elaborate.
Sorry, I've run out of time.
I'll leave it here for now mostly because I'm going to be late for something if I don't. There are several things that could go wrong along the way or things that might not make sense or give you exactly what you want. Like I said, I hope this is helpful, but feel free to contact me (or I'm sure many others on SAS-L) if it doesn't quite work for you.
