SYSDATE

SYSDATE is a valid default only for a DATETIME variable. If the YEAR TO FRACTION(5) is the declared precision of the variable, no qualifier is needed. Otherwise, you must specify the same DATETIME qualifier when SYSDATE is the default, as in the following example of a DATETIME variable:
DEFINE GLOBAL dt_var DATETIME YEAR TO DAY 
      DEFAULT SYSDATE YEAR TO DAY;
