Parameter names in JDBC methods

[Kristian Waagan]

Hello,

I have noticed that DatabaseMetaData.supportsNamedParameters returns 
false for Derby. We support using column names instead of indices in 
ResultSet, but JDBC methods using parameter names throw not-implemented 
exceptions (most of them are in CallableStatement, I think).

Am I correct in saying all JDBC methods using parameter names will throw 
not-implemented exceptions?
I am implementing CallableStatement.getCharacterStream, and I have the 
impression we are missing the basic functionality for using parameter 
names instead of indices. I do not know how much work it will be to add 
the feature, but I do not plan to add it in my current work.

I see there are some methods using parameter names in DERBY-1181. If my 
assumptions are confirmed, I will add a comment stating these methods 
will not be implemented, but throw not-implemented exceptions.
