SQL_FUNCTIONS=ALL allows for SAS functions that have slightly different
behavior from corresponding database functions that are passed down
to the database. Only when SQL_FUNCTIONS=ALL can the
SAS/ACCESS engine
also pass these SAS SQL functions to Informix. Due to incompatibility
in date and time functions between Informix and SAS, the Informix
server might not process them correctly. Check your results to determine
whether these functions are working as expected.
