SAS/ACCESS Interface to Aster passes the following SAS functions to Aster for processing. Where the Aster function name differs from the SAS function name, the Aster name appears in parentheses. For more information, see Passing Functions to the DBMS Using PROC SQL.
| ABS | MAX |
| ARCOS (ACOS) | MIN |
| ARSIN (ASIN) | MINUTE (date_part) |
| ATAN | MLOWCASE (lower) |
| ATAN2 | MOD (see note) |
| AVG | MONTH (date_part) |
| BYTE (chr) | QTR (date_part) |
| CEIL (ceiling) | REPEAT |
| COALESCE | SIGN |
| COS | SIN |
| COT | SQRT |
| COUNT | STRIP (btrim) |
| DAY (date_part) | SUBSTR (substring) |
| EXP | SUM |
| FLOOR | TAN |
| HOUR (date_part) | TRANWRD (replace) |
| INDEX (strpos) | TRIMN (rtrim) |
| LOG (ln) | UPCASE (upper) |
| LOG10 (log) | YEAR (date_part) |
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 Aster. Due to incompatibility in date and time functions between Aster and SAS, Aster might not process them correctly. Check your results to determine whether these functions are working as expected. For more information, see SQL_FUNCTIONS= LIBNAME Statement Option.
| COMPRESS (replace) | ROUND |
| DATE (now::date) | TIME (now::time) |
| DATEPART (cast) | TIMEPART (cast) |
| DATETIME (now) | TODAY (now::date) |
| LENGTH | TRANSLATE |
