Rick Hillegas commented on DERBY-2927:
--------------------------------------

Hi Dag,

I'm confused. I haven't looked at the patch but I thought you were moving in the direction of implementing procedures which return values. Going back through the comments, I see that you may be attempting something more modest: using JDBC escape syntax to call a function. Perhaps that functionality belongs on a separate issue. It seems to me that what is being asked for on this issue is a way to bind a SQL routine to a static method which both returns a value and supports IN, OUT, and IN/OUT args. Thanks.

>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 10.2.2.0
>         Environment: Java 1.4.2
> Windows XP SP 2

> 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.
