Re: Formula Question

i know this is not a formula but can you just subtract 1 from the year and
build the select statement like this:
move inputyear tyeara    4
eval inputyear = inputyear -1
move inputyear fyeara    4
move inputperiod perioda  2

eval sqlstm =  'select * from table where (digits(year)||digits(period)) >
"' + fyeara + perioda + '" and (digits(year)||digits(period)) <= "' + tyeara
+ perioda + '"'

Okay, this may be a difficult one. I have a simple table layout like this.

Company (4,0)
Year(4,0)
Period(2,0)
Amount(15,2)

I want to be able to take an ending period and determine 12 months back from
the ending date and select records in the DB via a select statement. We are
really close with the following formula: ( ( ( (period-12) / (period-12) ) *
12 ) - 11 )+period. A co-worker of mine got this far. If it wasn't for the
whole divide by zero bit as this portion ( (period-12)/(period-12) ) would
for period 12, it would work great. Short of a case statement is there a
better way to handle divide by zero? Or is the a better formula that we
aren't seeing?
