Barry,
How about
<cfparam name="FORM.selCategory" default="2">
<cfparam name="FORM.txtTitle" default="q">
<cfquery name="qArticle" datasource="weblog">
SELECT *
FROM tArticle
<cfif FORM.selCategory GT 0>
<cfif len(FORM.txtTitle)>
WHERE tArticle.idCategory = <cfqueryparam
value="#form.selCategory#" cfsqltype="CF_SQL_INTEGER">
<cfelse>
WHERE tArticle.idCategory = <cfqueryparam
value="#form.selCategory#" cfsqltype="CF_SQL_INTEGER">
AND tArticle.titleArticle
LIKE '%<cfqueryparam value="#form.txtTitle#"
cfsqltype="CF_SQL_VARCHAR">%'
</cfif>
<cfelse>
<cfif len(FORM.txtTitle)>
WHERE tArticle.titleArticle
LIKE '%<cfqueryparam value="#form.txtTitle#"
cfsqltype="CF_SQL_VARCHAR">%'">
</cfif>
</cfif>
</cfquery>
I have not tested it, but it should work...
And since you know about Stored Procedures, why not use them? They are
fast, more secure and the above is easy to archieve with them.
Taco
PS. Let me know if it works...

Subject: [cfaussie] <CFQUERY > SQL as a string command
Hi all.
I'm using some of my ASP tricks and trying to build a SQL statement as a
string (eg: with conditional WHERE clauses) and executed with <CFQUERY>
I'm getting "Syntax error in query expression" although the SQL
statement
itself looks - and works - fine.
To make the code (below) work, I've had to move the WHERE condition
building
to within the CFQUERY tag with the rest of the SQL
This works (sort of) in this simple example but it's not the way I like
to
work when things get more complicated.
is doing it this way (a string for a SQL command) impossible in CFMX?
eg:
<cfquery name="qArticle" datasource="weblog">
#strSQL#
</cfquery>
any ideas, thoughts, etc appreciated
cheers

(PS: yeah I know about SP's)
<!--- the code I'm using --->
<cfparam name="sqlWhereClause" default="" type="string">
<cfparam name="FORM.selCategory" default="2">
<cfparam name="FORM.txtTitle" default="q">
<cfif FORM.selCategory GREATER THAN 0><!--- category IS selected --->
<cfif trim(FORM.txtTitle) eq ""><!--- title clue NOT selected --->
<cfset sqlWhereClause = " WHERE tArticle.idCategory =
#form.selCategory#">
<cfelse> <!--- title clue IS selected --->
<cfset sqlWhereClause = " WHERE tArticle.idCategory =
#form.selCategory#
AND tArticle.titleArticle LIKE
'%#PreserveSingleQuotes(FORM.txtTitle)#%'">
</cfif>
<cfelse> <!--- category NOT selected --->
<cfif trim(FORM.txtTitle) neq ""><!--- title clue IS selected --->
<cfset sqlWhereClause = " WHERE tArticle.titleArticle
LIKE '%#PreserveSingleQuotes(FORM.txtTitle)#%'">
</cfif>
</cfif>
<cfset strSQL = "SELECT * FROM tArticle " & sqlWhereClause>
<!--- check how it looks --->
<cfoutput>#strSQL#</cfoutput>
<!--- run it --->
<cfquery name="qArticle" datasource="weblog">
#strSQL#
</cfquery>
