Edward Capriolo commented on HIVE-454:
--------------------------------------
Digging into this some more it seems that the query processor and cli driver
would have to work together in a different way.
As of now the CLIDriver is physically splitting on ';' it can not tell the
difference between ';' and '/;'. My patch adds some logic to detect '/;' and
unescape it before passing to qp.run(String).
Right now we can argue that the CliDriver has an implicit 'autocommit=true'. We
can make this an explicit variable. with autocommit='false' the query
processor would hold a StringBuffer or a queue of query strings. 'commit ' ;
would cause QP to run each query in its queue.
This is a non-trivial change. If we add this feature we can set autocommit=true
so the default behavior does not change. For no though my patch has a fairly
way to deal with this problem.
