Structure functions
You can use the following functions to create and manage structures in ColdFusion applications. The table describes
the purpose of each function and provides specific, but limited, information that can assist you in determining whether

All functions except
StructDelete
For more information on these functions, see the CFML Reference.
Description
If the custom tag was called without an

Add the employee data passed in the empinfo structure to the
Employees table of the cfdocexamples database.
Use direct references to the structure entries, not StructFind
functions.
If the database does not support automatic generation of the

query.
Display a completion message. This code does not have to be
