We have seen in previous chapters how to create variables and set values for those variables within ColdFusion. There are, however, some types of variables that can hold complex values or multiple values. These are what we refer to as complex data types. In ColdFusion development you will find that you can use complex data types, such as lists, arrays, structures, and queries, to greatly improve the performance and power of your applications.
In this chapter, we take a look at complex data types and show you how to create, set values for, and evaluate the data for use in your applications.
At the end of each section, we discuss the native ColdFusion functions associated with each type of data. We show you how to use them in real code and prove to you that they can make your programming life easier.
