Question

Is it possible to sort a query object by the length of a varchar column using Query of Queries in ColdFusion?

Answer 1

There is no way to do this entirely with QoQ, no: the QoQ implementation does not provide a len() function. Instead, you could get the database to provide the length data for you.

In the original query add:

len(fieldYouNed) as fieldYouNedLen

In the QoQ then use:

SELECT * FROM query ORDER BY fieldYouNedLen
