but I think you'll have to extract the file to disk.

Looks like I will, going by the answers so far. Oh well, I suppose there's worse! Thanks for the pointer re: File::Temp and tempdir's's CLEANUP flag, that sounds mighty useful.

(FWIW, performance wouldn't have mattered much. Famous last words, I know, but I really just need to run one SELECT query against this DB in order to extract the information I need.)
