Creating package-level associative array in java

问题

Is it possible to create a java representation of a package-level oracle associative array. For example, given the following:

CREATE OR REPLACE PACKAGE MyPackage AS
    TYPE t_numbers IS TABLE OF NUMBER INDEX BY PLS_INTEGER;

I find I cannot write the following java:

ArrayDescriptor descriptor =
    ArrayDescriptor.createDescriptor("MyPackage.t_numbers", connection);

(throws a SQLException "Invalid name pattern").

What is the correct syntax for an ArrayDescriptor referencing a package-level associative array? Does such a thing even exist?

You can also use OracleConnection.createOracleArray()

Note that arrayTypeName should be the table of type.

Also, you may find my my answer on getArray() and writeArray() useful.
