That sounds a lot like a background worker. > In case you are wondering why could anyone need something like that: I'm looking for a way to implement a small subset of HTSQL (see [ http://htsql.org/], of course not with the whole HTTP protocol) natively in one of popular RDBMS without extra URL-to-SQL conversion. Yes, I know that a lot of hard work was done for making query plans, optimizing etc. but I'm still really wish to do this for some very specific needs. I'm not going to completely replace the SQL and thus will be happy to do those manipulations on a SQL 2008-compliant DBMS. > Good luck with that :-) -- Guillaume
