Charles explained sysdummy1 pretty good. Often used in STRSQL to test
certain functions like
select current_date from sysibm/sysdummy1
Now, it's been deprecated by the VALUES statement.
VALUES CURRENT_DATE
....+....1
VALUES
2009-05-12
You can even do a
VALUES CURRENT_DATE INTO :HostVar
Which may make more sense than a dummy read of a file (like
sysibm/sysdummy1) to get a value.
See also:
values date(current date)
values date('2009-05-12')
values date('2009-02-31')
VALUES
++++++++++
values month(date('2009-05-12'))
Or last day of previous month
values day(
date(substr(char(date(current date)),1,8) concat '01')
- 1 day)
or
values
case
dayofweek(
date(substr(char(date(current date)),1,8) concat '01'
- 1 day)
when 1 then 'Sunday'
when 2 then 'Monday'
when 3 then 'Tuesday'
when 4 then 'Wednesday'
when 5 then 'Thursday'
when 6 then 'Friday'
when 7 then 'Saturday'
End
Will give you 'Thursday'.
