Re: [GENERAL] get the previous assigned sequence value

Orakle's fault :-) I remembered there was a thorough (very thorough)
discussion months before. This raises a question: because the web
based search engine is slow, why can't setup a text file achive?
so that people can ftp the big file and use vi do whatever they
want locally? does using the search engine increase potential value
to the site? if in that case, I'd better shut up ;-), but I can not
see any, it is rather a load burden. perhaps some commercialization
plan for future?
