You can use structKeyExists() on a query to determine whether or not it includes a column of a specified name. This is useful, for instance, in validating uploaded spreadsheets, because cfspreadsheet gives you a query object back.

However, the .keyExists() member function for queries is not implemented.

I think it should be. What's the harm?

Comments:

While Calling structKeyExists(), Coldfusion explicitly convert an object to Map if possible. Same can't be done in for member function call. For member function, the object has to be an instance of Map object.

I do not accept that response, Awdhesh. "It's hard" is not a valid excuse for doing something that will make the language better. Here, let me do part of your job for you: You write a KeyExists member function on your query class that converts the row to a map, then checks to see if the key exists.

Same as with exceptions: just implement the same interface on queries. Simple. And what is the status of "open / totest" supposed to mean?

Added keyExists for Query via query object. Added new Query function (not diverting the call to StructKeyExists).
