Steven Hawkins resolved TEIID-5729.
-----------------------------------
    Resolution: Done


The problem here is actually that the auto value for the update count is being treated the same as no updates.  However to get an actual value that requires fully planning the procedure as the closest logic we have comes from the requires transaction logic on the plan.  That is quite involved, so the initial fix is just to be safe and map instead to an action.  The docs have been updated to say that an explicit updatecount of 0 is expected to map to a function.

> This is a follow up regarding https://issues.jboss.org/browse/TEIID-5725
> As discussed there, Teiid currently does not map virtual procedures and functions to odata functions and procedures according to the notion of "side effect free"
> Please introduce a mechanism to allow for a mapping according to adequate odata semantics.
