ColdFusion Introduction to ColdFusion Using ColdFusion Variables Tutorial

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.

ColdFusion automatically creates some variables that provide information about the results of certain tags or operations. ColdFusion also automatically generates variables in certain scopes, such as Client and Server. For information on these special variables, see the CFML Quick Reference and the documentation of the CFML tags that create these variables.

ColdFusion does not support variables with Null - or no - values. Therefore, ColdFusion generates an error when it tries to use a variable before it is created. This can happen, for example, when processing data from an incompletely filled form. To prevent such errors, test for the variable's existence before you use it. For more information on testing for variable existence, see Developing ColdFusion Applications .
