Subject Re: [jira] Commented: (DERBY-925) Implement new JDBC 4 metadata API getFunctionParameters()
Date Fri, 03 Mar 2006 17:48:28 GMT
I have noticed on the JDBC4 EG mailing list that this method appears to 
be going through revisions.  Lance, do you have the latest on this?

4.0. The result set it returns now conatains a number of new columns and is, in fact, a super
set of the columns returned by getFunctionParameters. For JDBC 4.0 it will likely be necessary
to extend the existing GetProcedureColumns.java VTI with much of the same information that
I was thinking about putting into the new VTI. Perhaps both methods can be implemented with
queries against a single VTI? We will probably need a separate getProcedureColumns40 query
in metadata.properties to maintain backward compatibility?
