     [ https://issues.jboss.org/browse/TEIID-2150?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-2150.
-----------------------------------

    Resolution: Done

Updated the resolving logic to allow defaultable end parameters.  This will enable adding procedure parameters to existing procedures and not break existing sql.

> We should allow procedures to be called positionally and use default values for end parameters if they are not specified.
> Condiser:
> create foreign procedure proc (x integer, y string);
> If you currently issue "call proc()", we'll assume named parameters and use "call proc(null, null)".
> If you issue "call proc(1)", you'll get an exception.  The new behavior would be to use "call proc(1, null)".
> Of course something like "call proc('a')" would still result in an exception.
