Problem Note 20130: Aliases columns or aliased tables in the SQL procedure blocks Implicit Pass-Through
 |  |  |  |  |
Using the LIBNAME statement as the access method, PROC SQL queries that contain aliased in-line views, aliased columns, or aliased tables can cause incorrect textualization of the query.
Incorrect query textualization can prevent Implicit Pass-Through from passing the query to the associated database for execution. As a result, the query will be executed in SAS® instead. Significant performance problems can occur because of the potential for retrieving large amounts of data that are returned to SAS before the processing is finished.
