SAS/ACCESS Interface to OLE DB passes the following SAS functions for OLE DB to DB2, Microsoft SQL Server, and Oracle for processing. Where the OLE DB function name differs from the SAS function name, the OLE DB name appears in parentheses. For more information, see Passing Functions to the DBMS Using PROC SQL.

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 OLE DB. Due to incompatibility in date and time functions between OLE DB and SAS, OLE DB might not process them correctly. Check your results to determine whether these functions are working as expected.
