Dag H. Wanvik updated DERBY-2927:
---------------------------------

    Attachment: derby-2927-diag-3.stat
                derby-2927-diag-3.diff

Uploading derby-2927-diag-3, which:

- improves code comments in StaticMethodCallNode
- wraps the LangProcedureTest in an English locale decorator so the test case testDerby2927 can assert on the new message strings as well as the (shared) SQL state.

> First off, this is not really a bug, it's more of a restriction.
>  
> As per the needs of my inhouse framework I need a procedure to be able to return a value other than
> a ResultSet (I need a integer). The reason I need to use a procedure; is because I'm using INOUT parameters.
>  
> When call my procedure, it needs to look like this:
>  
> { ? = call myProcedure(?,?,?,?,?,?)}
>  
> Where the first ? represents a status-code, ie a failure = -1, and a successfull would be 1.
> All the other procedure paramters are INOUT.
>  
> If I where to use normal scripting methods in any other DB, for instance DB2 or Oracle
> then I would be able to do this. It seems that the problem has to do with using
> JAVA "Stored" Procedures.
>  
> Is it possible to either make procedures return primitive types, OR
> for Functions to be able to use OUT and INOUT paramters?
>  
> I've got High Hopes for Derby, but it's issues like this that might just
> sway me to use a different DB.
>  
> I appreciate any feedback you can give me.
