Eva -

I dredged this out of some ancient code that I wrote against a 7.2 database. The inner trunc functions were there to get rid of the time - I don't remember why the outer trunc function was there at this point
(it was five years ago). This doesn't get you completely there, but
will hopefully get you started.

Decode
(sign(30-(trunc(trunc(SysDate)-trunc(col_date)))),
1,'30 days',null)

Hello Listers,

I need some help please,
I am trying to create a DECODE statement, on a date column and looks something like this, but does not work.
SELECT COL1,

                COL2,
                DECODE((SYSDATE - COL_DATE), <= 30, '30_days', NULL)
Days30,
                DECODE((SYSDATE - COL_DATE), (between 31 and 60), '60

Days',
NULL) Days60,
.......
.......
FROM ACCOUNT_TBL
WHERE COL = '0' Obviously, I have worked out that this can not be done. The problem is also
that the server is 7.3.4 and I need to use the code in a view. Does anyone have any solutions/work arounds for this? Any help will be appraciated.

TIA
