How do you display rows from a cfoutput query 20 rows at a time with clickable link to see next 20 when their are over 200 recs. The query is sql 2005 and CF8 to display. I use a standard table to display the recs.

Firstly, take a look at both the following:
http://paginationcfc.riaforge.org/
http://listpages.riaforge.org/

Secondly, the basic way is to pass a URL parameter for the start row.  Code might be something like this (this is a very basic version but should give you an idea of how to proceed).

<cfparam name="URL.start" default=1>
<cfset Max = 20>	<!--- set this as a variable, allows you to easily change it later --->
 
<cfquery name="getData" ...>
	...
</cfquery>
 
<cfoutput query="getData" startrow="#URL.start#" maxrows="#Max#">
 
</cfoutput>
 
<cfif URL.start - Max GT 1>
<!--- previous pages --->
	<a href="?start=#(URL.start-Max)#">Prev</a>
</cfif>
 
<cfif URL.start + Max LTE getData.RecordCount>
<!--- more pages --->
	<a href="?start=#(URL.start+Max)#">Next</a>
</cfif>

if your data is just text and the look of your table is not significant (i.e. you do not have strict requirements on the colors, fonts, etc), then check out <cfgrid> tag - in CF8 it now comes in HTML format. it's a quick way to add paginated query display to your page, but customizing it to look any different from its default look is a true pain...

otherwise... see if these links help you:

(the second one is SQL Server 2005 specific and uses rather complicated stored procedure)

hi leadco
replace the filename with the file where u r implementing the pagination and replace the queryname with the query u r using...
<cfparam name="more" default="1">
		<cfif isdefined ("more")>
		<cfset still_more=#more#+20>
		</cfif>
	<cfset i=0>
		<cfoutput query="queryname" startrow="#more#" maxrows="20">
</cfoutput>
<table>
		<tr>
			<td>
				<table width="750">
				<tr>
					<td align="right">
					<cfoutput>
					<cfif #more# is not 1><br>
						<a href="filename.cfm?more=#evaluate(more-20)#"><< Previous 20 Records</a>
					</cfif> 
					</td>
					<td  align="right">
					<cfif #still_more# lte queryname.recordcount>
						<cfif #evaluate(still_more+9)# gt queryname.recordcount>
					<cfoutput>#evaluate(still_more+9)#</cfoutput>
						<cfset next_record_count=#queryname.recordcount# mod 20><br>
						<a href="filename.cfm?more=#still_more#">>> Next #next_record_count# Records</a>
						<cfelse><br>
					<cfoutput>#evaluate(still_more+9)#</cfoutput>
						<a href="filename.cfm?more=#still_more#"> >> Next 20 Records</a>
						</cfif>
					</cfif>
					</cfoutput>
					</td>
			 </tr>
			</table>
		</td>
	 </tr>
	</table>
