Hello Steven,
I came up with a further question regarding virtual procedures. The question is related to
transactions. Let's say I have multiple Teiid instances running which access the same
mysql database, or alternatively other clients with direct access to the mysql database.
Do I explicitly have to wrap my virtual procedures and functions which I write in the ddl
file into a transaction? And how would the command syntax for this look like?
Further question regarding visibility of stored procedures and functions. I learned from a
discussion with Ramesh, that there is a visibility attribute which I can set on the entire
schema to set all tables and functions inaccessible. However, in that case I would have to
wrap each table I like to export to odata into a view, which seems like odd extra work for
me.
My thinking is the following. If I have a stored procedure or function in the source
database, I would like to use it within my virtual procedures but at the same time would
not like to allow access via odata. Would it be possible to add a visibility option to the
procedure definition in the dll definition? Or does something similar already exist?

Please improve documentation on definition of stored procedures,
virtual functions and virtual procedures

https://issues.jboss.org/browse/TEIID-5725
Project: Teiid
Issue Type: Enhancement
Reporter: Christoph John
Assignee: Steven Hawkins
Priority: Critical
I refer to the discussion with Ramesh in
https://developer.jboss.org/message/989048#989048 and would like to ask for a more
detailed explanation on how to write virtual procedures and functions.
-Especially, how are OUT and INOUT params set and how can they be obtained via odata.
- How is the return value of a virtual function set?
- How are collections and arrays of collections returned?
