RE: DECODE or not to DECODE
Thanks To all for the support! I managed to use a combination of thesuggestions which worked great! Denham -Original Message- Sent: Monday, August 04, 2003 4:24 PM To: Multiple recipients of list ORACLE-L 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.

RE: DECODE or not to DECODE
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.

Re: DECODE or not to DECODE
One possibility that comes to mind is to write a really, really long DECODE: DECODE((SYSDATE - COL_DATE), 1, '30_days', 2, '30_days', 3, '30_days', ... NULL) Days30 But there must be a better possibility. Perhaps use the SIGN function: DECODE ( SIGN((SYSDATE - COL_DATE)-30), -1, '30_DAYS', 0, '30_DAYS', NULL) If the difference is 1-29, subtracting 30 will result in a negative value, and SIGN will return -1. If the difference is exactly 30, the subtraction will result in 0, and SIGN will return 0. The only other possible return is 1, for positive numbers, and I let the default (NULL) handle that case. My guess is that you could do something similar for your second DECODE statement, though the math would get a bit more complex. I'd have to think a bit longer to work up a solution, but I'm optimistic that there is one. Hope this helps.
