Subject [jira] Commented: (DERBY-319) Derby returns incorrect values for "LENGTH" column of DatabaseMetaData.getProcedureColumns() result set.

    [ http://issues.apache.org/jira/browse/DERBY-319?page=comments#action_12313084 ] 

David Van Couvering commented on DERBY-319:
-------------------------------------------

I took a look at this patch and it looks good, very clean and well-documented.  Looks like
you also covered
some types that were missing in the metadata test.

My only question was why some of the columns in the metadata test  alltypes table, some of
the columns 
have lots of underscores in them.  I couldn't follow the logic for this.

It compiles fine.  I am running derbyall and will add a separate comment regarding that when
it completes.

> Based on discussion from the following thread:
> http://article.gmane.org/gmane.comp.apache.db.derby.devel/2585
> The Derby implementation of DatabaseMetaData.getProcedureColumns() returns incorrect
values for the "LENGTH" column of the result, primarily because there is no clear definition
in the JDBC spec regarding what this method is _supposed_ to return.  Discussion in the above-posted
thread concluded that the intent of the JDBC metadata is to "match the ODBC metadata", at
least regard to this particular issue.  So changes reflecting this conclusion should be submitted
to Derby.
