How to use different SQL Server databases in SAS?

pietinma — Thu, 13 Dec 2018 13:26:36 GMT

I use different databases in my SAS scripts. In Oracle I can define a database using a schema statement:

libname o1 oracle user=&user pw=&pw path=&path dbprompt=no schema="db1";

libname o2 oracle user=&user pw=&pw path=&path dbprompt=no schema="db2";

How can I do the same in SQL Server? How do I define, that I don't want to use master but db instead? This does not work:

LIBNAME SQL ODBC DSN="DSN" user=&user pw=&pw schema="db";

Define "does not work". There are a gazillion of "don't works", so how should we know which one hits you?

Read the log (Maxim 2), and post it here.

Also do a google search (Maxim 6) for the text of an ERROR or WARNING message, if you get one.

The idea is right, most likely the syntax is wrong. So you know the dsn works, you've tested that portion already?

I don't think the dsn name needs to be in quotes. This also assumes you're not on a server, otherwise that's a different issue.

This is my connection string to a DB2 instance, something like this should work for you as well.

libname home odbc schema="dbo" noprompt="server=SERVERNAME,PORT#;DRIVER=SQL Server;Trusted_Connection=yes;database=databasename";

Thanks,

You tracked me down. SAS does not give any erros messages. I thought that it should give an error message if my schema database doesn't exist. I tried this in Oracle:

libname o oracle user=&user pw=&pw path=some_path dbprompt=no schema="not_existing_database";

No error messages in log though there is a typo in the database name. Why? Database queries to "existing_database" don't work, of course.

libname o oracle user=&user pw=&pw path=some_path dbprompt=no schema="existing_database";

No error messages in log. Database queries to "existing_database" work.

In SQL Server the following statement does not point libname SQL to "existing_database" and database queries to "existing_database" don't work. The actual LIBNAME statement does not give any error messages. The connection to the server succeeds, however.

LIBNAME SQL ODBC DSN="server" user=&user pw=&pw schema=existing_database;

35 LIBNAME SQL ODBC DSN="server" user=user pw=pw schema=existing_database;
NOTE: Libref SQL was successfully assigned as follows:
Engine: ODBC
Physical Name: existing_database

I couldn't get schema definition to function. I just must create a new data source (DSN) for every database by using Microsoft ODBC Administrator. It is not very handy while then I have many SQL Server drivers for one server connection. I thought that I could create only one data source in ODBC Administrator, define default database and use SAS schema definition to make queries to other databases.
