I would advise against using global temporary table across multiple CF pages. CF data sources don't give you the fine control you would need to guarantee that connections across separate page requests will use the same database connection session. Global temporary tables will be dropped (in MS SQL) as soon as the session which created them is closed, assuming they are not currently in use by another session. In CF the underlying server controls the closing of connections, not the developer. An alternate approach, as previously suggested, would be to use standard tables.
