Problem Note 20199: The same query produces different results when submitted using the Pass-Through Facility in SAS/ACCESS® Interface to Teradata and using Teradata BTEQ
 |  |  |  |  |
When you submit a query using the SQL Procedure Pass-Through Facility in SAS/ACCESS Interface to Teradata, the results in SAS might not be the same as the results from the same query when submitted using Teradata BTEQ.
When a column is not selected in SAS but is selected in Teradata, SAS will bypass that column. SAS also fails to bypass the NULL indicator that goes with that column.
As a result, if a NULL column is not selected followed by a NOT-NULL column that is selected, the NOT-NULL column will be treated as NULL.
To work around this behavior, the Pass-Through select list must match the select list in SAS, if any of the columns are NULLABLE.
