SAS/ACCESS Interface to Impala passes the following SAS functions to Impala for processing. Where the Impala function name differs from the SAS function name, the Impala 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 Impala functions that are passed down to Impala. Only when SQL_FUNCTIONS=ALL can the SAS/ACCESS engine also pass these SAS SQL functions to Impala. Due to incompatibility in date and time functions between Impala and SAS, Impala might not process them correctly. Check your results to determine whether these functions are working as expected.
| COMPRESS (REGEXP_REPLACE) | DATETIME (NOW()) |
| DATE (CURRDATE()) | TODAY (CURRDATE()) |
| DATEPART (TO_DATE()) |
