A number of code examples in the ColdFusion Developer's Guide reuse code, particularly queries. To illustrate the advantages of CFCs, these examples invoke the appropriate method in the CFC that appears in the following example. Although Adobe recommends using CFCs to create structured, reusable code, some code examples in this manual contain queries within a CFML page, rather than invoking a CFC, in order to clearly illustrate a particular element of ColdFusion.
