Dynamic dates for calendar

Question

HI Folks,
Can anyone please tell me how I can create dates dynamically
for my quey?
I use the following query to query for events:
SELECT *
FROM events
LEFT JOIN eventtype
ON events.eventtype=eventtype.typeid
WHERE
(eventstart BETWEEN #startof# AND #endof#
OR eventend BETWEEN #startof# AND #endof#)
I would like to add previous month and next month links can
anyone tell me how I can add these to my query?
Thankyou

Hi,
Here's an example for the query as well as the previous-,
next-month links.
please note: your query is not correct, it would not return
any events that start before the selected timeframe and end after
the selected timeframe. Have a look below for a better way to query
for "overlapping dates".
cheers,

<cfparam name="year" default="#year( NOW() )#">
<cfparam name="month" default="#month( NOW() )#">
<cfset startdate= createdate(year,month,1)>
<cfset previousdate= dateadd("m", -1, startdate )>
<cfset nextdate= dateadd("m", +1, startdate )>
<cfoutput>
<strong>QUERY:<br></strong>
SELECT *<br>
FROM EVENTS<br>
WHERE event_start < #createodbcdate( nextdate )#<br>
AND event_end >= #createodbcdate( startdate )#<br>
<br>
<strong>NAVIGATION:<br></strong>
<a href="?YEAR=#YEAR( previousdate )#&MONTH=#month(
previousdate )#">PREVIOUS MONTH</a><br>
<a href="?YEAR=#YEAR( nextdate )#&MONTH=#month(
nextdate )#">NEXT MONTH</a><br>
</cfoutput>
