The CURRENT TIME special register specifies a time that is based on a reading of the time-of-day clock when the SQL statement is executed at the application server. If this special register is used more than once within a single SQL statement, or used with CURRENT DATE or CURRENT TIMESTAMP within a single statement, all values are based on a single clock reading.
Using the CL_SCHED table, select all the classes (CLASS_CODE) that start (STARTING) later today. Today's classes have a value of 3 in the DAY column.
SELECT CLASS_CODE FROM CL_SCHED
WHERE STARTING > CURRENT TIME AND DAY = 3
