Using Access engines like OLEDB, ODBC or ORACLE result in an

  Error: Invalid Operation
  Error: Termination due to Floating Point Exception

when using the CASE statement with missing values(s) in SAS 9.1.

The same code works in SAS 8.2 and SAS 9.0.

An example of SAS code which gives the above error message is:

   (CASE WHEN x.abc > 0 THEN x.def/x.abc ELSE . END)

The problem only occurs with missing value(s) in the CASE expression.
If you use all non-missing value(s), the query will execute
successfully.

A workaround is to use DIRECT_SQL=NO in the LIBNAME statement. Setting
DIRECT_SQL=NO on the LIBNAME statement indicates that generated SQL is
not passed to the DBMS for processing.
