RE: An easy (I think) SQL question

Hi Bill
Look up iDate - google is your friend
I installed it on our system a couple of years ago - because I was having problems with converting a field supposedly representing a date, but contained a glut of non date values
IDate was a god send

Subject: An easy (I think) SQL question

Hello all,

I have what I think is a fairly simple SQL question but it's baffling me.
I have a field in a file that is a date (field is in packed format). The date in the field looks like this: 1160628. The need is to only grab records from this file that go back 3 months from the first day of the current month, so in this case I'd only want records with a date greater than 1160301. This also needs to work if when subtracting the 3 months I had to go across multiple years. I know I can do a formula something like
this:

(CURRENT_DATE - (DAY(CURRENT_DATE)-1) DAYS - 3 MONTH)


But I'm not sure how to use the packed numeric date field I have to get
there. Any thoughts would be greatly appreciated. Thanks!


Bill
