Home -> Community -> Mailing Lists -> Oracle-L -> RE: Using DUAL
Dan:
The discussion was recent, but I cannot find reference to it.
I kinda thought Kirti was involved in the thread, and it had something to do
with creating an x$dual table as a workround to hammering dual.
Sorry I can't remember any more . . .
