Your options are somewhat limited in 9i but for me that query runs in less than one second. There’s no reason that you should have to wait 24 hours on this query. It hasn’t changed in Toad since version 12.8, so I think if there were something really wrong with it, we would have heard about it before now.
You can try that query in the editor with various optimizer hints. If you get one that makes it go faster, you can go to Options -> Oracle -> Optimizer Hints, and add a row for DBA_CONS_COLUMNS with 9i as the Oracle version and then Toad will use whatever hint you plug in.
You might want to try Database -> Optimize -> Auto Optimize SQL. That will generate several rewrites and try them automatically. If you get lucky, one of them will just be an optimizer hint and you can plug in into Toad.
You might also want to look at your database - maybe there is a lot of memory swapping going on or something like that and you can throw some more memory at it.
