Subject: [Pljava-dev] Array Support
Message-ID: <497F8274.8020300@mssm.edu>

I just started using PL/Java and it works very well.  Compared to what 
has to be done in Oracle to start creating functions in Java, it is 100 
times easier.

In Oracle, I have functions like:

CREATE OR REPLACE FUNCTION count(match varchar,neg varchar,args vNum) 
RETURN number deterministic as language java name 
'whdpPkg.countMatch(java.lang.String, java.lang.String,oracle.sql.ARRAY) 
return double';

Where "vNum" is a: CREATE OR REPLACE TYPE vNum as TABLE OF NUMBER;
Basically, an array of numbers (numerics).

Ideally in Postgres/PLJava I would like to:

CREATE OR REPLACE FUNCTION count(match varchar,neg varchar, args 
numeric[]) RETURNS numeric as 'whdpPkg.countMatch(java.lang.String, 
java.lang.String, ?????)' LANGUAGE java;


Is this possible? Is there a "oracle.sql.ARRAY" equivalent for Postgres?
What work is required to support something like this?

Thanks,
