When you use SAS/ACCESS Interface to DB2 to connect to the DB2 database, the SAS^® System looks for tables that are owned or created by the user ID that is listed in the LIBNAME statement. If the software does not find any tables associated with that user ID, the SAS log still shows that the library was assigned successfully, as shown in the following example output:

libname mylib db2 user=user-id password=password datasrc=data-source-name;
NOTE: Libref MYLIB was successfully assigned as follows:
Engine:        DB2

However, no tables appear in the library in the SAS Explorer window, as shown here:

The library does not show any tables because there are no tables owned or created by the user ID from the LIBNAME statement. Therefore, you need to define a schema in the LIBNAME statement. A schema is the owner or creator of tables. To see tables that are owned or created by a different user, you must use the SCHEMA=schema-name option in the LIBNAME statement.

To determine the schema for your tables, follow these steps:

1. Submit the following code using your DB2 user ID, password, and data source:
   proc sql; connect to db2 (datasrc=data-source-name user=user-id password=password); create table work.db2schema as select * from connection to db2 (select TABSCHEMA, TABNAME from syscat.tables order by tabschema); disconnect from db2; quit;

   After you run the code, open the created table to see the schema and table names:

   

2. Scroll through the Work.db2schema table to find the owner name for the table that you want to see.
3. Use the owner name for that table as the value in the SCHEMA= option in your LIBNAME statement. For example, if you want to see the MY_CLASS table, you must use SCHEMA=DBITEST in the LIBNAME statement, as shown here:
   libname mylib db2 user=user-id password=password datasrc=data-source-name schema=dbitest;

When you submit the LIBNAME statement in this example, the tables with a schema value of DBITEST appear in the Explorer window.

Note: When you connect to DB2, the schema name can, at times, case sensitive. Therefore, you need to try the schema name in the following four ways:

• all lowercase (for example, schema=dbitest)
• all uppercase (for example, schema=DBITEST)
• all lowercase with double quotation marks (for example, schema="dbitest")
• all uppercase with double quotation marks (for example, schema="DBITEST")
