Subject: Selecting different views from a Boolean expression
Date: Mon, 26 Mar 2007 09:36:10 -0400
Message-ID: <7CCC5BEF5E72394C963E529B54EB4A642A198C@SD01ITMV12.PROD.NET> (raw)

Hi there, 
I have a web based reporting system that I am coding.  I need to be able
to view statistics by the calendar year or the fiscal year depending on
what the user selects.

My issue is how do I change y select statements to change the column
output?

Example

Incident		Jan 	Feb	Mar	Apr	May	June
July	Aug	Sep	Oct	Nov	Dec
=======	===	===	===	====	===	====	===	====
====	====	====	====
Falls		1	1	0	0	0	0	0
0	0	0	0	0

Overdose	0	1 	0	1	1	1	0
0	0	1	1	0



But if the user selects fiscal year the output could be:


Incident		Jun 	Jul	Aug	sept	Oct	Nov
Dec	Jan	Feb	Mar	Apr	May
=======	===	===	===	====	===	====	===	====
====	====	====	====
Falls		1	1	0	0	0	0	0
0	0	0	0	0

Overdose	0	1 	0	1	1	1	0
0	0	1	1	0


I have created select views for each month possibility, but I don't know
how to select the view I need from an IF/Then/else statement!!

Any help would be appreciated.

Thanks
