Query error - with filtering records

Question

Hi. I have a gallery that shows 9 records at a time, which
you can then move on to subsequent pages. I added filters to narrow
down the record search, however, I am receiving query errors. This
is my code:
<!----- This is setting the initial defaults for the filter
variables ---->
<cfparam name="form.ART_CATEGORY_ID" default="">
<cfparam name="form.ART_TYPE_ID" default="">
<cfparam name="form.FINE_ART_CLASS_ID" default="">
<cfparam name="form.searchfield" default="">
<!----- Populate the CATEGORIES filter drop-down ---->
<cfquery name="categories" datasource="nancy">
SELECT *
FROM CATEGORIES
ORDER BY ART_CATEGORY_ID
</cfquery>
<!----- Populate the TYPES filter drop-down ---->
<cfquery name="types" datasource="nancy">
SELECT *
FROM TYPE
ORDER BY ART_TYPE_ID
</cfquery>
<!----- Populate the CLASS filter drop-down ---->
<cfquery name="class" datasource="nancy">
SELECT *
FROM CLASS
ORDER BY FINE_ART_CLASS_ID
</cfquery>
<!----- Create the filter drop-down selections ---->
<form method="post" action="root_fineart.cfm">
<select name="ART_TYPE_ID">
<option value="" <cfif trim(form.ART_TYPE_ID) eq
"">selected
</cfif>> All </option>
<cfoutput query="types">
<option value="#ART_TYPE_ID#"
<cfif form.ART_TYPE_ID eq
types.ART_TYPE_ID>selected</cfif>>#ART_TYPE#</option>
</cfoutput>
</select>
<select name="ART_CATEGORY_ID">
<option value="" <cfif trim(form.ART_CATEGORY_ID) eq
"">selected
</cfif>> All </option>
<cfoutput query="categories">
<option value="#ART_CATEGORY_ID#"
<cfif form.ART_CATEGORY_ID eq
categories.ART_CATEGORY_ID>selected</cfif>>#ART_CATEGORY#</option>
</cfoutput>
</select>
<select name="FINE_ART_CLASS_ID">
<option value="" <cfif trim(form.FINE_ART_CLASS_ID) eq
"">selected
</cfif>> All </option>
<cfoutput query="class">
<option value="#FINE_ART_CLASS_ID#"
<cfif form.FINE_ART_CLASS_ID eq
class.FINE_ART_CLASS_ID>selected</cfif>>#FINE_ART_CLASS#</option>
</cfoutput>
</select>
<!----- This also creates a SEARCH capability ---->
<input name="searchfield" type="text" size="10"
value="#form.searchfield#" /></cfoutput> </label>
<input name="submit" type="submit" value="Submit" />
<!----- I got this part of the code from a site, that allows
me to display the 9 records at a time in my gallery ---->
<cfparam name="start" type="numeric" default="1">
<cfparam name="step" type="numeric" default="9">
<!----- My query to retrieve the records... This may be where
I have something wrong... ---->
<cfquery datasource="nancy" cachedwithin=".01"
name="queryResults">
SELECT *
FROM ART
WHERE 1 = 1
<cfif val(form.ART_CATEGORY_ID) GT 0>
AND ART_CATEGORY_ID = <cfqueryparam
value="#form.ART_CATEGORY_ID#" cfsqltype="cf_sql_integer">
</cfif>
<cfif val(form.ART_TYPE_ID) GT 0>
AND r.ART_TYPE_ID = <cfqueryparam
value="#form.ART_TYPE_ID#" cfsqltype="cf_sql_integer">
</cfif>
<cfif val(form.FINE_ART_CLASS_ID) GT 0>
AND i.FINE_ART_CLASS_ID = <cfqueryparam
value="#form.FINE_ART_CLASS_ID#" cfsqltype="cf_sql_integer">
</cfif>
<cfif trim(form.searchfield) neq "">
AND ART_TITLE LIKE '%#form.searchfield#%'
</cfif>
ORDER BY ART_TITLE ASC
</cfquery>
<!----- This is also code I got somewhere else to display the
gallery ---->
<cfif queryResults.recordcount gt 0>
<cfoutput>
<p class="style1">
<!--- if past start --->
<cfif (start-step-step) gt 1>
<a href="#cgi.SCRIPT_NAME#?start=1"><img
src="images/Beginning_blue.png" alt="Beginning" width="31"
height="21" align="absbottom" /></a>
</cfif>
<cfif start gt 1>
<a href="#cgi.SCRIPT_NAME#?start=#start-step#"><img
src="images/previous_blue.png" alt="Previous" align="absbottom"
/></a>
</cfif>
<strong>#start# - #iif(start * 3 + step gt
queryResults.recordcount,queryResults.recordcount,start + step-1)#
of #queryResults.recordcount# records</strong>
<!--- if still some not displayed --->
<cfif (start + step) lte queryResults.recordcount>
<a href="#cgi.SCRIPT_NAME#?start=#start+step#"><img
src="images/next_blue.png" alt="Next" align="absbottom"
/></a>
</cfif>
<cfif (start+step+step) lte queryResults.recordcount>
<a
href="#cgi.SCRIPT_NAME#?start=#queryResults.recordcount-step+1#"><img
src="images/end_blue.png" alt="End" align="absbottom"
/></a>
</cfif>
</p>
</cfoutput>
</cfif>
<cfloop query="queryResults" startrow="#start#"
endrow="#start + step/3-1#">
<table width="100%" border="1" bordercolor="#FFFFFF"
cellspacing="0" cellpadding="2">
<tr> <cfoutput query="queryResults"
startrow="#start#" maxrows="3">
<td width="33%"
class="style1">#queryResults.ART_TITLE#</td>
</cfoutput>
<cfset #start# = #start# + 3>
</tr>
</table>
</cfloop>
</td>
</tr>
</table></form>
It seems that the CATEGORIES filter is the only one that does
not return a ERROR EXECUTING DATABASE QUERY error. However, it does
not filter all the records... it only seems to filter and return
the first 4 or 5 records.
Any thoughts?

Answer 1

your queryResults query selects only from ART table, while in
the WHERE
clause you are apparently using other tables whihc are not in
your FROM
clause...
you need to use JOIN/INNER JOIN/LEFT JOIN/RIGHT JOIN in your
FROM clause
to link the other tables. check your db manual for proper
usage of those
operators.
