[teiid-issues] [JBoss JIRA] (TEIID-3750) Allow the parsing of an expression

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-3750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13592194#comment-13592194 ] 

Steven Hawkins commented on TEIID-3750:
---------------------------------------

> FUNCTION execution does not work

That is not supported.  There is no concept of a default value for a parameter and only positional invocation is supported (whereas procedures support named parameters)

> According to docs, VIRTUAL FUNCTION can have DEFAULT value specified.

Could have been a copy and paste error from procedures.  It's not supported, so that should be corrected.

> Now that we have an extension property, we could allow an expression to be used in parsing rather than just a string.
