MIDNIGHT_SECONDS

The MIDNIGHT_SECONDS function returns an integer value that is greater than or equal to 0 and less than or equal to 86 400 representing the number of seconds between midnight and the time value specified in the argument.


>>-MIDNIGHT_SECONDS--(--expression--)--------------------------><

expression: An expression that returns a value of one of the following built-in data types: a time, a timestamp, a character string, or a graphic string. It must not be a CLOB or DBCLOB, and its value must be a valid string representation of a time or timestamp. For the valid formats of string representations of times and timestamps, see String representations of datetime values.

The result of the function is large integer. If the argument can be null, the result can be null; if the argument is null, the result is the null value.

Examples

Find the number of seconds between midnight and 00:01:00, and midnight and 13:10:10. Assume that host variable XTIME1 has a value of '00:01:00', and that XTIME2 has a value of '13:10:10'.
```
  SELECT MIDNIGHT_SECONDS(:XTIME1), MIDNIGHT_SECONDS(:XTIME2)
    FROM SYSIBM.SYSDUMMY1
```
This example returns 60 and 47410. Because there are 60 seconds in a minute and 3600 seconds in an hour, 00:01:00 is 60 seconds after midnight ((60 * 1) + 0), and 13:10:10 is 47410 seconds ((3600 * 13) + (60 * 10) + 10).
Find the number of seconds between midnight and 24:00:00, and midnight and 00:00:00.
```
  SELECT MIDNIGHT_SECONDS('24:00:00'), MIDNIGHT_SECONDS('00:00:00')
    FROM SYSIBM.SYSDUMMY1
```
This example returns 86400 and 0. Although these two values represent the same point in time, different values are returned.
