Hi!
Just a quick note, the multi-table delete,update code was removed from
the tree. This was in an early list and just never happened.
Problems with it:
1) Multi/non-multi had different execution paths.
2) Test cases were added in 5.0 (since it hadn't really had testing).
3) The syntax was not in the SQL standard, and worse causes issues
with VIEWS longterm.
4) Caused a number of conflicts in the parser (all gone).
5) A single wrapped transaction gives you exactly the same thing.
6) WITH RETURNS was not possible with this in the code (which is...
well a thousand times more useful)
I did it as one large patch. Syntax aside.. if someone wanted to fix
the execution paths it might be ok to have, but it adds in all sorts
of other unresolved syntax issues.
I am working through a number of half completed features/oddballs
right now. This was the only user visable one.
As a heads up we are looking at refactoring our milestones right now
to bring Drizzle into production sooner.
Cheers,
-Brian
