Good potential job interview question

I've just solved a problem and then realized it could serve as a great
job interview question:

You have an auto-generated SQL select query with 1000 or so columns
being selected. Each selected column uses a combination of functions.
One of them uses a combination the SQL server cannot handle. The error
message does not tell you which one. Describe a method to track down
the trouble column in a reasonable amount of real time  without
modifying the query generating code or creating an automated tool.
