This is a minor annoying issue that had been bothering me for a few years (!) and was finally resolved with a ticket to SAS Tech Support. I have several libname statements that I have been using to connect to DB2 databases. In the past, the libname statements all ran successfully, and I was able to query the tables in the databases. However, when I tried to view the tables under my assigned libraries in the SAS Explorer window by clicking on the libname, the libraries appeared empty. This was irritating since I either had to use another tool if I wanted to browse the tables and look at the actual data, or rely on Proc Contents.

The answer to the problem turns out to be that some schemas are case-sensitive. SAS Tech Support suggested trying the following libname statements:

libname CRDM1 db2 dsn=crdm schema=appdm uid=xxxxx pwd=xxxxxx sql_functions=all dbindex=yes;

libname CRDM2 db2 dsn=crdm schema=”appdm” uid=xxxxx pwd=xxxxxx sql_functions=all dbindex=yes;

libname CRDM3 db2 dsn=crdm schema=APPDM uid=xxxxx pwd=xxxxxx sql_functions=all dbindex=yes;

libname CRDM4 db2 dsn=crdm schema=”APPDM” uid=xxxxx pwd=xxxxxx sql_functions=all dbindex=yes;

The first and second libname statements didn’t display the tables, but the last two with the schema in all CAPS both worked.
