I have a statement like this:
<cfif string contains "this" or string contains "that" or etc.>
The contains comes from a database that might be two or more things to search for in the if statement. How can I write the cfif to keep adding OR until all of the things to search for are in the if statement above?

There are a couple of ways to achieve your goal. One is to use list functions.
<cfif ListFind(ValueList(YourQuery.YourField), YourString) gt 0>
That would be appropriate if you want your string to be one of the values. Or you could do something like this, which would match the logic from your question.
</cfscript>
MyString = "DISCHARGE";
SearchResult = false;
</cfscript>
<cfquery name="x" datasource="dw">
select trim(event_name) event_name
from event
</cfquery>
<cfloop query="x">
<cfif MyString contains event_name >
<cfset SearchResult = true>
<cfbreak>
</cfif>
</cfloop>
<cfdump var="#SearchResult#">
And then there is the ever popular query of queries.
<cfquery name="q2" dbtype="query">
select count(*) matches
from YourFirstQuery
where TheField like <cfqueryparam value="%#string#%">
</cfquery>
These all have slightly different logic, so you have to know what you want to do before you try to code it.

Coldfusion Complex Construct

I am trying to construct a coldfusion conditional statement that looks for incremental form ID checkboxes to have been selected. All checkboxes are defined as Component[component number]. I have established a loop that is looking for a URL variable that is different for every form that calls on the condition as seen below. The issue I am having is that I recieve an error when executing that tells me "Complex constructs are not supported with function parameterexists."
Clearly it has to do with the dynamic nature of the parameterexists statement, but I do not fully know what this means. Can anyone explain this and also offer a solution? I am fairly new to coldfusion and coding, so take it easy on me.
<cfloop from="1" to="#URL.loopcounter#" index="loopvar">
<cfif parameterexists(Form.Component#loopvar#)>
INSERT INTO Results (MP_Barcode, Reworked, Reworked_By)
VALUES ('#Form.MontaplastBarcode#', 'YES', '#URL.BadgeNumber#')
</cfloop>
<cfoutput>
<p class="success">YOUR REWORK HAS BEEN SUBMITTED SUCCESSFULLY.</p>
</cfoutput>
<cfelse>
<p class="error">NO REWORK WAS SUBMITTED. NO COMPONENTS SELECTED.</p>
</cfif>
Depending on the form that calls on this action, the URL loopcounter variable could range from 1 to 50.
To answer the question, there are several ColdFusion functions that won't allow you to create a dynamic name before the function evaluates it. parameterExists() was one of those. Both isDefined() and structKeyExists() will allow dynamic variables. So will the member function of structKeyExists() > structName.keyExists("theKey").
Again, if you are new to ColdFusion, I'd simply pretend you never saw parameterExists(). I believe it has been listed as "deprecated" since CF 4.5 or somewhere around there. That's almost 20 years ago. That function has actually become somewhat of a joke about how Adobe never really throws away their trash.
As I pointed out above, I'd get rid of it completely and go with structKeyExists(). I also don't know what your whole page is doing, but with the code you provided, I'd change it to something like this:
<cfloop from="1" to="#url.loopcounter#" index="loopvar">
<cfoutput>
<cfif structKeyExists(form,"Component#loopvar#")>
<!--- SANITIZE INPUTS --->
<cfset inMontplastBarcode = sanitizingFunction(FORM.MontaplastBarcode)>
<cfset inBadgeNumber = sanitizingFunction(URL.BadgeNumber)>
<!--- Now use sanitized inputs in query with queryparams --->
<cfquery name="InsertStuff" datasource="myds">
INSERT INTO Results (MP_Barcode, Reworked, Reworked_By)
VALUES (
<cfqueryparam value="#inMontaplastBarcode#" cfsqltype="cf_sql_varchar" maxlength="50">
, 'YES'
, <cfqueryparam value="#inBadgeNumber#" cfsqltype="cf_sql_varchar" maxlength="20">
)
</cfquery>
</cfif>
</cfoutput>
</cfloop>
In your database, Reworked should be a boolean datatype. It appears that it may be a 'Yes' or 'No' string. A true boolean will be a) smaller and b) easier to validate. In the cfqueryparams, if you are using a cf_sql_varchar datatype, make sure you set an appropriate max length. You'll need to look at the available CF datatypes and see how they match up to your database datatypes. (Also see https://cfdocs.org/cfqueryparam)
For your sanitizingFunction() that you'll use to sanitize your input variables, you'll want to write a function that will follow through the steps to clean up your variables to strip out unsafe characters or other things you don't want. That is an entirely different, extremely large topic all on its own.
In your form, name your checkboxes simpler. Like reworked01 through reworked50.
On the action page use cfparam to default them to zero (since html forms don't post unchecked boxes):
<cfloop from="1" to="#url.loopCounter#" index="i">
<cfparam name="form.reworked#numberFormat(i, 00)#" default="0">
</cfloop>
Then instead of fumbling with whether or not a variable exists, you can instead look for the value:
<cfloop from="1" to="#url.loopCounter#" index="i">
<cfif evaluate("form.reworked"&i) eq 1>
<!--- some logic here --->
<cfelse>
<!--- some other logic here --->
</cfif>
</cfloop>

Is there a shorter way to do this than qoq in coldfusion

I often have to switch between a code and name from a query in my code. Here's what it looks like:
<cfquery name="AllLocations" >
Select Name, Code From Locations
</cfquery>
Later in the page I will need the name and have the code, or visa-versa:
<cfquery name="ThisLocation" dbtype="query >
Select Name From Locations where Code = '#Code#'
</cfquery>
<cfoutput>#ThisLocation.Name#</cfoutput>
Is there a shorter way to do this so I don't have to do the qoq every time?
You could do something like this:
<cfoutput>
#allLocations.name[listfind(valuelist(allLocations.code), code)]#
</cfoutput>
Edit starts here
Given the comment about performance, I understand that arrays are faster than lists.
<cfoutput>
#allLocations.name[arrayFind(allLocations['code'], code)]#
</cfoutput>

Use FindNoCase to find url string

I've search around and find some valuable info. about FindNoCase but I have not yet found the answer to this specific question.
I'm using FindNoCase to find "/us/" in the url and then process some code. This works fine for one country site.
<cfif FindNoCase("/us/",#cgi.SCRIPT_NAME#)>
Process some code here.
</cfif>
My question is: Is there a way to find the piece of the url, "/xx/", for multiple country sites and process the same code between the cfif tags? For example "/us/", "/ca/", "/mx/", etc.
Hopes this makes sense.
If searching for multiple different codes among a string, I'd use REFindNoCase. Make a regex like so (/us/)|(/ca/) which would look for /us/ or /ca/ and per the documentation (http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-7e99.html) you can return the sub-expressions and reference them.
No looping required.
REFindNoCase("(/us/)|(/ca/)", URL, 1, true)
To reference the strings you would do:
<cfset URL = 'domaim.com/page/us/' />
<cfset match = REFindNoCase("(/us/)|(/ca/)", URL, 1, true) />
<cfif arrayLen(match) GT 0>
<cfset value = Mid(URL,match.pos[1],match.len[1]) />
<cfswitch expression="#value#">
<cfcase value="/us/">
<!--- Do something for US match --->
</cfcase>
<cfcase value="/ca/">
<!--- Do something for CA match --->
</cfcase>
<!--- ETC --->
</cfswitch>
<cfelse>
<!--- Do something if no match found --->
</cfif>
In this case, value would equal /us/. Or it should anyway. I'm writing all of this here and not actually testing on my server. You'd have to adjust this if you want to cover multiple matches in a string.
If I'm understanding your question correctly, you want to process the SAME code for several countries, if detected in the URL. You could just create a database of country codes you want to process a certain way (CountryTableXYZ), query it, then loop through that query so it'll search the URL for each entry you have in the table.
<cfloop query="CountryQuery">
<cfif FindNoCase("#countryCode#",#cgi.SCRIPT_NAME#)>
Process some code here.
</cfif>
</cfloop>
At least that's how I interpret it. If I'm not correct please let me know or clarify your initial post.

I am new bie on coldfusion, Please help me to get All ID, Name, Type Using CFLOOP?
<cfset categoryList = application.salesforce.queryObject("SELECT Id, Name FROM Category__c") />
<cfdump var="#categoryList#">
<cfloop list="#structKeyList(categoryList)#" index="key">
<cfdump var="#categoryList[key]#">
</cfloop>
The above Code give me the below result : true 3
This is a pretty basic question you could have easily found my googling, but here you go anyway.
<cfoutput>
<cfloop query="queryName">
#queryName.ID#
#queryName.name#
#queryName.type#
</cfloop>
</cfoutput>
Note you can replace cfloop with cfoutput and remove the cfoutput around everything.
I would just use a "cfoutput" tag...
<cfoutput query="yourquery">
#yourquery.ID#
#yourquery.name#
#yourquery.type#
</cfoutput>
Based on the updates that you have made to your question it looks like you might need to do something like this:
<cfoutput>
<cfloop query="categoryList.results">
<p>#id# - #name# - #type# </p>
</cfloop>
</cfoutput>
Note that I have not tested this code

Using coldfusion.sql.QueryTable.next() in Coldfusion 9

I am trying to write a custom tag that will iterate over a cfquery object in a special way. I found this page: http://www.zrinity.com/developers/mx/undocumentation/query.cfm outlining how to use the underlying java methods to navigate the result set, but it doesn't seem to be working in CF9.
I can call .next(), .previous(), .first(), and .last() just fine, and each method updates query.currentRow, but referencing query.columnName always returns the value from the first row, not currentRow.
Example:
<cfquery name="testQuery" datasource="source">
SELECT FooName FROM NumberedFoos
</cfquery>
<cfloop from="1" to="3" index="i">
<cfoutput>#testQuery.currentRow# => #testQuery.fooName#</cfoutput><br />
<cfset testQuery.next()>
</cfloop>
Produces:
1 => Foo 1
2 => Foo 1
3 => Foo 1
I know i could use something like testQuery.fooName[testQuery.currentRow], but that is pretty undesirable for the people I am making the custom tag for. Was the functionality described in the above link removed from CF9? If so is there an alternative?
EDIT
To expand on the why, the client wants a custom tag that allows them to "assert" certain things about a query. The client has a pretty low level understanding of CF, but are pretty solid writing SQL. Their desired end result is something akin to:
<cfquery name="purchaseTotals">
SELECT PurchaseId, Total FROM Purchases
</cfquery>
<CF_ASSERT query="purchaseTotals">
purchaseTotals.Total gte 0
</CF_ASSERT>
The desired output would be a html table with each row being the row from the query that fails the assertion. So to me, the CF_ASSERT tag need to be able to update the current row.
Edit 2:
The main challenge is to allow html in the body of the tag, while still having query values substituted from the appropriate row:
<CF_ASSERT query="purchaseTotals">
<CF_CONDITION expression="purchaseTotals.Total gte 0">
<!---error message when expression is false--->
<cfoutput>
Purchase #purchaseTotals.purchaseId# has a negative total!
</cfoutput>
</CF_CONDITION>
<CF_CONDITION expression="purchaseTotals.Total eq ''">
#PurchaseTotals.purchaseId# has a null total, this may be caused by:
<ul>
<li>Edge Case 1</li>
<li>Edge Case 2</li>
</ul>
</CF_CONDITION>
<CF_ASSERT>
The output here would be something like:
Purchase 120 has a negative total!
Purchase 157 has a negative total!
Purchase 157 has a null total, this may be caused by:
Edge Case 1Edge Case 2
Was the functionality described in the above link removed from CF9?
The internal stuff has definitely changed since the article was written in 2006. But I suspect the exact functionality you are describing may not have existed in any mx version. A key difference between your code and the linked examples is the usage of <cfoutput query=".."> (not just a plain <cfoutput>). The query attribute obviously provides some extra context when evaluating the variables. Remove it (like in your example) and the results are "the value from the first row, not currentRow.". Even under MX6, which does not bode well for subsequent versions. That exact functionality probably was not removed. It just never worked to begin with.
If so is there an alternative?
Like I said earlier, the cleanest approach would be to use array notion ie #query.column[row]#. Given that you seem to have rejected that option, you are basically left with evaluate(). You would need to loop through the query within the parent tag. Then use evaluate to process the subtag expression and content. It is not particularly elegant or simple IMO. But I think that may be good as it gets without array notation, or a ritual sacrifice of some kind.

solid writing SQL
Having said all that, are things being implemented this way because it is the best approach or because it is most similar to writing SQL ie comfortable ?
Classic example of the inner platform effect.
I would advise you not to do this as you are trying to create a system which mimics built in functionality of the base or running system which ultimately becomes a poorly implemented version of the system in which it is running on / implemented in.
Sounds confusing, I know - but this is a well known anti-pattern to avoid.
See here for more information : http://en.wikipedia.org/wiki/Inner-platform_effect
P.s. what you are looking for (although I disagree with the implementation) is itteration of a query outside of a cfloop, simply use array syntax :
#queryName.fieldName[rowNumber]#
Using this you can itterate the query however you wish, certainly no need for underlying java. Notice we aren't using queryName.currentRow. For previous() next() functionality, you just change the rowNumber up or down.
