[OASIS Issue Tracker] (ODATA-739) Allow default values for function and action parameters

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

    [ https://issues.oasis-open.org/browse/ODATA-739?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=59545#comment-59545 ] 

Ralf Handl commented on ODATA-739:
----------------------------------

We could add a special symbol that can be used in URLs to "provide" the default value:

GET RevenueForecast(Year=$default,Currency=$default)
GET Companies(42)/RevenueForecast(Year=$default,Currency=$default)


This would allow to uniquely identify the overload based on function name, binding parameter type, and non-binding parameter names.

> In SQL, function and stored procedure parameters can have default values (used when no value is specified for the parameter).  We should consider allowing action and function parameters to have default values as well.
