Using ColdFusion Variables - A ColdFusion variable is created by assigning a value to it. Most commonly, you create variables by using the CFSet tag. You can also use the CFParam tag and assignment statements in CFScript. Tags that create data objects also create variables. For example, the cfquery tag creates a query object variable

Creating Variables in Coldfusion - Tutorial for Creating Variables, including Kinds of Variables, Client Variables, Server Variables, and Session Variables

The form and variables Scopes - Variables can be a little confusing as you set out to learn ColdFusion, they needn't be, but we do need to understand about variable scopes and how ColdFusion handles them. If we don't get a handle on that, well it can lead to a few problems and we'll investigate those problems as we progress.

Coldfusion Foundations - A variable is a named location in memory that holds a value. The "type" of variable refers to the type of data stored at that memory location.

How do I pass a complex variable (query, array, structure ) from one ColdFusion page to another? - You have constructed a complex datatype and want to pass the entire structure (with data) to another ColdFusion page to use.

Using Variables in Coldfusion - This article takes a look at variables, how they are created, the types of information they can contain, and how we can begin to harness their power in our web applications.

Variables In Cold Fusion - In this article I'm going to cover one of the most fundamental things that is in every programming language. Variables, now don't get scared, in ColdFusion they're dead easy to use. Unlike Dynamic SQL statements in ASP, they won't make your brain hurt.

Using ColdFusion Variables - We've seen what types of variables exist, now lets see how we use them. In ColdFusion code, variables come in the form of variabletype.variable. Wherever we want to have a variable value used in your code you have to use #variabletype.variable#. Therefore if we wanted to output the browser information, the clients IP address we would do the following. Again, I'll do the code and explain it later

 

Shared Scope Variable Locking - This will teach you how to lock shared scope variables. This can lead to the elimination of some problems and poosibly major conflicts in your server.

Understanding Coldfusion Variables - A variable is "a quantity capable of assuming any of a set of values."

Creating Coldfusion Variables - In some other languages you have to specify what kind of variable it is, example: string, number, integer or text. You don’t have to do that in ColdFusion, because Coldfusion determines the variable type by the way it being used. That is one of the reasons why some programmers call Coldfusion a type less language.

Scope of a variable - Compared to the scope of a variable in JavaScript, ColdFusion has more fine grained scope definition for its variables

Using Sessions Variables - Questions you may have about session variables are: Exactly, what are session variables? How are they applied to a given session? What is an example of the use of session variable? The lesson will try to answer those questions.

Using Variables in Coldfusion - How to use variables in Coldfusion, including Creating Variables, Variable Characteristics, Data Types, Passing Variables to Custom Tags & Functions, Data Type Conversion, and Scopes
