In SAS^® Scalable Performance Data Server^®, incorrect results might be generated when you use the LIBNAME statement option IP=YES and an SQL procedure that contains date calculations in a WHERE clause. The problem occurs because of incorrect implicit pass-through processing, the results of which are passed to SAS Scalable Performance Data Server.

Note: This problem occurs in SAS 9.1.3 Service Pack 4 if Hot Fix E9BC46 has been applied.

Suppose, for example, that you have the following calculation in a WHERE clause:

The calcualation is transformed into the following during the implicit pass-through processing:

This condition is passed by PROC SQL to SAS Scalable Performance Data Server, which then evaluates the condition to the following:

Because the software incorrectly evaluates the clause to 0, it interprets the value to be '01jan1960'd, as shown here:

To avoid incorrect results, either omit the IP= option in the LIBNAME statement or use IP=NO.
