Building URL Dynamically - coldfusion

I am trying to build a URL dynamically, i have a product feature table which holds the url. The purpose of this exercise is for a user to click on a link;
www.domain.com/climbing-frames_rockwall/ then the user can click on another link www.domain.com/climbing-frames_rockwall_step-ladder (rockwall and step-ladder are individual features). Each time a user clicks on a link i need to append the next feature.
So far i have
<cfset filterURL = "" />
<cfif IsDefined('url.feat') AND url.feat NEQ "">
<cfquery name="geturl" datasource="#application.dsn#">
SELECT txt_feat_url
FROM tbl_features
WHERE uid_features=<cfqueryparam cfsqltype="cf_sql_integer" value="#url.feat#">
</cfquery>
<cfset filterURL = filterURL & "_" & geturl.txt_feat_url>
</cfif>
Its not appending though?
Jason

You are setting filterURL = "" at the top. So, in the following line you are just appending geturl.txt_feat_url to a blank string:
<cfset filterURL = filterURL & "_" & geturl.txt_feat_url>
That is why you are ending up with values such as "_monkey-bar" instead of "climbing-frames_rockwall-ladder_monkey-bar".Where are you expecting the value of filterURL to come from, is it the URL scope?

conditional query in coldfusion

I need to provide some status on items in my table which I do in the last column of my table.
First I go and query one table to see if I have a confirmation for the item .
<cfquery name="focnotice" datasource="******" result="FocResult">
SELECT ecspc
FROM tbl_CNR_H
WHERE icsc = '#myarray[i].ICSC#'
AND asr_no = '#myarray[i].ASR#'
</cfquery>
The ECSPC is a field in my Table, so logic is see if there is a record. If so, see if the ECSPC value is something other then "". If so, query another table to see if there is a matching record for this ECSPC.
<cfset ISUPStatus = "#focnotice.ecspc#">
<cfif ISUPStatus NEQ "">
<cfquery name="isupStatus" datasource="******" result="ISUPResult">
select *
from tbl_ISUP
where dpc = '#ISUPStatus#'
</cfquery>
<cfset isupcount = #ISUPResult.RecordCount#>
<cfif #isupcount# GT 0>
<cfset ISUPorder = "Yes">
<cfelse>
<cfset ISUPorder = "No">
</cfif>
<cfelse>
<cfset ISUPorder = "No">
</cfif>
I get the following error in my debug
Complex object types cannot be converted to simple values.
The expression has requested a variable or an intermediate expression
result as a simple value. However, the result cannot be converted to a
simple value. Simple values are strings, numbers, boolean values, and
date/time values. Queries, arrays, and COM objects are examples of
complex values. The most likely cause of the error is that you tried
to use a complex value as a simple one. For example, you tried to use
a query variable in a cfif tag.
What am I missing here ?
You are passing invalid parameter into the Query "myarray[i].ICSC",'#myarray[i].ASR#'. You need to specify what index of array you are using.
<cfquery name="focnotice" datasource="*******" result="FocResult">
Select ecspc
From tbl_CNR_H
Where icsc = <cfqueryparam cfsqltype="cf_sql_varchar" value="#myarray[1].ICSC#">
AND
asr_no = <cfqueryparam cfsqltype="cf_sql_varchar" value="#myarray[1].ASR#">
</cfquery>
I believe the error causing you the issue lies in:
<cfset isupcount = #ISUPResult.RecordCount#>
From a quick look of your code, try using instead:
<cfset isUpCount = isUpStatus.recordCount>
But in addition please look at the comments above, especially joins.

ColdFusion Query-of-Queries Wildcard LIKE condition not working with single quotes?

I have a query-of-queries that performs a LIKE condition on a variable string:
When the variable contains a single word that includes a single quote, some results are returned, but not all:
<cfset _myVar = "Women's" />
<cfquery name="_qData" dbtype="Query">
SELECT
ID
FROM MyQoQ
WHERE NAME LIKE '%#_myvar#%'
OR DESCRIPTION LIKE '%#_myvar#%'
</cfquery>
When the variable contains more than one word, and one of those words includes a single quote, no records are returned:
<cfset _myVar = "Women's Initiative" />
<cfquery name="_qData" dbtype="Query">
SELECT
ID
FROM MyQoQ
WHERE NAME LIKE '%#_myvar#%'
OR DESCRIPTION LIKE '%#_myvar#%'
</cfquery>
I've tried PreserveSingleQuotes() as well as wrapping the varaibles with CFQUERYPARAM, but, to no avail - I get the same results.
Is there a way to make this work?
Adding in a repro case
<cfset myQuery = queryNew('hello')>
<cfset queryAddRow(myQuery,5)>
<cfset querySetCell(myQuery,"hello","what up",1)>
<cfset querySetCell(myQuery,"hello","what's up",2)>
<cfset querySetCell(myQuery,"hello","what's up friends",3)>
<cfset querySetCell(myQuery,"hello","what u",4)>
<cfset querySetCell(myQuery,"hello","what",5)>
<cfdump var="#myQuery#">
<cfquery name="res" dbtype="query">
SELECT *
FROM myQuery
WHERE hello LIKE <cfqueryparam cfsqltype="cf_sql_varchar" value="%$what's up%">
</cfquery>
<cfdump var="#res#">
Railo 4.1.1.009 - returns both results (rows 2 and 3)
ColdFusion 10,0,13,287689 - returns no results
If I change my SQL to
WHERE hello LIKE '%what''s up%'
I still get no results
aarh!! a classic case of royal pain in the rear.
To solve this, you have to add an extra ' to every ' in your search term, there by escaping it.
<cfset myQuery = queryNew('hello')>
<cfset queryAddRow(myQuery,5)>
<cfset querySetCell(myQuery,"hello","what up",1)>
<cfset querySetCell(myQuery,"hello","what's up",2)>
<cfset querySetCell(myQuery,"hello","what's up friends",3)>
<cfset querySetCell(myQuery,"hello","what u",4)>
<cfset querySetCell(myQuery,"hello","what",5)>
<cfdump var="#myQuery#">
<cfset x = "what's up" />
<cfquery name="res" dbtype="query">
SELECT *
FROM myQuery
WHERE hello LIKE <cfqueryparam cfsqltype="cf_sql_varchar" value="#replace(x, "'", "''", "all")#%">
</cfquery>
<cfdump var="#res#">
if you do this directly, as you mentioned,
WHERE hello LIKE '%what''s up%'
the parser is going bonkers. But, if you pass the value via a function return value, the run time assignment of values via a variable somehow makes the parser happy.
I remember using such tricks in sending multiple SQL statements delimited with ';' in cfquery. Directly writing
"DECLARE x NUMBER; SELECT 2 INTO x FROM DUAL;"
inside cfquery fails, but assigning them to a string and then sending the string as a return value for any string manipulator function (lcase, ucase, etc) worked perfectly.
Note: the problem is solved, but if my explanation and approach is diff, feel free to correct and comment.
I'm running ColdFusion 10 u13.
Modifying your repo code this seemed to work:
<cfset myQuery = queryNew('hello')>
<cfset queryAddRow(myQuery,5)>
<cfset querySetCell(myQuery,"hello","what up",1)>
<cfset querySetCell(myQuery,"hello","what's up",2)>
<cfset querySetCell(myQuery,"hello","what's up friends",3)>
<cfset querySetCell(myQuery,"hello","what u",4)>
<cfset querySetCell(myQuery,"hello","what",5)>
<cfdump var="#myQuery#">
<cfquery name="res" dbtype="query">
SELECT *
FROM [myQuery]
WHERE [hello] LIKE <cfqueryparam cfsqltype="cf_sql_varchar" value="%what''s up%">
</cfquery>
Note the double single quotes in the <cfqueryparam> tag. Like Dan I would have thought that the <cfqueryparam> tag would have taken care of this for you automatically. Perhaps this is a bug in QoQ?

ColdFusion cfset issue

I am new to ColdFusion. Anyone know why this code is not working. When I leave the form null it is not showing 100 in the database.
<cfif isdefined("FORM.Percentage")>
<cfset Form.Percentage = #Form.Percentage#>
<cfelse>
<cfset Form.Percentage = 100>
</cfif>
<cfquery name="percent" datasource ="abc">
Insert into Employees
(Percentage)
Values
(#Form.Percentage#)
</cfquery>
If you have a textbox it is submitted to the form even if it's left blank, so you want to check if the field was left blank. If it was then you can set the default.
You'll also want to do some server side validation that the value is a number and use cfqueryparam for inserting your value into the database.
<cfif NOT len(trim(FORM.Percentage))>
<cfset Form.Percentage = 100>
<cfif>
<cfquery result="percent" datasource="abc">
Insert into Employees (Percentage)
Values (
<cfqueryparam cf_sql_type="cf_sql_integer" value="#Form.Percentage#">
)
</cfquery>
When using cfquery with an INSERT the name attribute doesn't provide anything. Using result would allow you to view some data about the query if needed, but generally it shouldn't be used.
You could also have dumped form to the screen by using <cfdump var="#form#"> to see what it was returning. If you want to check that the key exists for a radio button or checkbox you can use structKeyExists(form,'myCheckbox') rather than using isDefined().

Set a variable dynamically into a structure via CFLOOP

I am trying to set a variable dynamically into a structure via CFLOOP. I have read Ben Nadal's blog post but cant seem to get the assignment correct. I would like to use dot notation and make the VIN a sub structure of values.
Here is my code:
<cfloop query="VINs">
<cfquery name="carsQue" datasource="carsData">
SELECT VIN, MODEL, MAKE, etc
FROM CarsDB
WHERE (VIN = #VIN#)
</cfquery>
<cfset carsStruct= StructNew()>
<cfset carsStruct.[VIN].MAKE = '#carsQue.MODEL#'>
<cfset carsStruct.[VIN].MODEL = '#carsQue.MAKE#'>
</cfloop>
Any guidance would be greatly appreciated,
Thanks
Running a query inside a loop is almost always a bad idea. In your case, a better option would be:
<cfif ListLen(valuelist(vins.vin)) gt 0>
<cfquery name=CarsQue datasource = "carsData">
select vin, model, make, etc
from carsDB
where vin in (<cfqueryparam cfsqltype="cf_sql_varchar"
value="#valuelist(vins.vin)#" list="true">)
</cfquery>
<cfset carsStruct = StructNew()>
<cfloop query="carsQue">
code for your struct
</cfloop>
<cfelse>
code for vins query returning no data
</cfif>
Better yet would be to get all the data with one query. You didn't provide enough information to determine if this was possible, but it often is.
Create a structure outside loop and and setting variable within loop can solve the problem. in a current scenario each time loop run its create a new structure.
you can do some thing like this
<cfset carsStruct= StructNew()>
<cfloop query="VINs">
<cfquery name="carsQue" datasource="carsData">
SELECT VIN, MODEL, MAKE, etc
FROM CarsDB
WHERE VIN = <cfqueryparam cf_sql_type="cf_sql_varchar" value="#VINs.VIN#">
</cfquery>
<cfset carsStruct[VINs.VIN].MAKE = carsQue.MODEL>
<cfset carsStruct[VINs.VIN].MODEL = carsQue.MAKE>
</cfloop>
Based on the limited information you've given you should be able to run one query and loop through that to add to your struct.
<cfset carsStruct= {}> //new struct
<cfif VINs.RecordCount> //your VINs query has records
<cfquery name="carsQueue" datasource="carsData">
SELECT VIN, MODEL, MAKE, etc
FROM CarsDB
// Quoted list of all your VINs. cfqueryparam prevents against SQL injection
WHERE VIN IN (<cfqueryparam cf_sql_type="cf_sql_varchar" value="#ValueList(VINs.VIN)#" list="true">
</cfquery>
<cfloop query="carsQueue">
<cfset carsStruct.[carsQueue.VIN].MAKE = carsQueue.MODEL>
<cfset carsStruct.[carsQueue.VIN].MODEL = carsQueue.MAKE>
</cfloop>
<cfelse>
// if VINs query return nothing a blank struct will be returned.
//You do NOT need this <cfelse> unless you are returning something when the query is blank
</cfif>

ColdFusion having multiple cfqueries in cffunction

I am trying to write a function for a survey where it pulls questions from a database. The catch is that there are both active and unactive questions. I need older questions to show up when someone views the results from an old survey.
Here is the code I am trying within a CFC:
<cffunction name="getAllQuestions" access="public" returntype="query">
<cfargument name="survey" default=0>
<cfif len(#survey#) gt 0>
<cfquery name="getsdate" datasource="blah.database">
select * from past_survey
where survey_id = #survey#
</cfquery>
<cfreturn getsdate>
</cfif>
<cfquery name="getquestions" datasource="blah.database">
select * from pool_questions
<cfif len(#survey#) eq 0>
where active_flag='Y'
<cfelse>
where <cfqueryparam value="#dateformat
(getsdate.survey_date, "yyyy/mm/dd")#"> BETWEEN start_date AND
end_date
</cfif>
order by qtn_nb
</cfquery>
<cfreturn getquestions>
</cffunction>
#survey# is the survey id which is generated by the form. What I am trying to do is that if survey has a value to run query getsdate. Then the second query would run no matter if survey has a value or not. If there is not value it should pull all active questions. If there is a value then it should check if the survey date is between the start date and end date for past questions.
Any advice on how to make this work would be greatly appreciated. Thank you in advance!
<cffunction name="getAllQuestions" access="public" returntype="struct">
<cfargument name="survey" required="true" default="0" type="numeric">
<cfset var qryReturn = ""> <!---Always var scope your variables to prevent them from leaking to other functions --->
<cfset var structReturn = structNew()>
<cfset structReturn.pastSurvey = "">
<cfset structReturn.surveyQuestions = "">
<cfif survey GT 0>
<cfquery name="qryReturn" datasource="blah.database">
SELECT *
FROM past_survey
<!--- Always cfqueryparam to prevent SQL injection attacks & also always reference the scope to prevent confusion --->
WHERE survey_id = <cfqueryparam cfsqltype="cf_sql_integer" value="#arguments.survey#">
</cfquery>
<cfset structReturn.pastSurvey = qryReturn>
<cfelse>
<cfquery name="qryReturn" datasource="blah.database">
SELECT *
FROM pool_questions
<cfif arguments.survey EQ 0>
WHERE active_flag = 'Y'
<cfelse>
WHERE <cfqueryparam value="#dateformat
(getsdate.survey_date, "yyyy/mm/dd")#"> BETWEEN start_date AND
end_date
</cfif>
ORDER BY qtn_nb
</cfquery>
<cfset structReturn.surveyQuestions = qryReturn>
</cfif>
<cfreturn structReturn>
</cffunction>
You probably should be doing this in two separate functions, but I will attempt to answer your question.
My code will return a struct of queries (you can change to an array if you prefer) that returns a past survey and the survey questions
Note: In your example code, you have a few bad practices.
You are checking the length of the survey value rather than checking the value itself.
If you want to ensure that survey always has a value regardless of if it is passed or not, set requried=true and give it a default value.
Use cfqueryparam to prevent sql injection attacks
Any variables created in the function need to be var scoped to prevent them from leaking to other cffunctions in the same cfcomponent. I always do this at the top. Yes, even the name you give a cfquery needs to be var scoped.
Since you are doing a return after your first query, if the survey value is greater than 0 it will never get to the second query where it has the date check.
I see the following problems you need to address.
First, your survey argument has a default value of 0 and you are doing conditional logic on the length of it. The length of "0" is 1, so that condition will always return true.
Next, you state that you want the 2nd query to run whether the first one runs or not, but you refer to a value from the 1st query in the 2nd one. That means if the 1st query does not run, the 2nd one will crash due to an undefined variable.
Next, dateformat returns a string. Applying it the way you do in the 2nd query is at best unnecessary, and at worse, and indication that you are storing the start and end dates in pool_questions as strings. If you are attempting to strip out the time portion of the datefield in the first query, ColdFusion has a cast() function for that.
Also, scope your variables. ie - instead of <cfif len(survey), do this <cfif len(arguments.survey).
Also, var your local variables. In this case, it's the names of your two queries.
That should get you started.
