"invalid name pattern" when trying to user packaged TYPE

Question

Hi,
I have problem with creating ArrayDescriptor instance of packaged DB TYPE.
There is declared TYPE
   type OBJ_ARRAY_TYPE is table of number(30)
in a DB package specification,
when i try to create description through jdbc, it fails on "java.sql.SQLException: invalid name pattern: PKG_NAME.OBJ_ARRAY_TYPE":
   desc = ArrayDescriptor.createDescriptor ("PKG_NAME.OBJ_ARRAY_TYPE", conn);
When OBJ_ARRAY_TYPE defined globally, outside the package, everything works fine. Is it limitation of JDBC(classes12.jar)/OracleDB9i not to allow using packaged types?
Thx for any suggestion.

Answer 1

I have same hiccup with 10g JDBC Driver (ojdbc14.jar) and 9i Database.
Test Case: Create the package with the type and a procedure that use this type as OUT parameter. Create a java application to invoke this procedure and consume the type.
Steps:
Create following package.
CREATE OR REPLACE PACKAGE test_type AS
  type avarchartabletype IS TABLE OF VARCHAR2(256) INDEX BY binary_integer;
  PROCEDURE getvcttdata(avcttdata OUT avarchartabletype,   irows IN OUT INTEGER);
END test_type;
CREATE OR REPLACE PACKAGE BODY test_type AS
  PROCEDURE getvcttdata(avcttdata OUT avarchartabletype,   irows IN OUT INTEGER) AS
  BEGIN
    FOR i IN 1 .. irows
    LOOP
      avcttdata(i) := 'Yo ' || i;
    END LOOP;
  END getvcttdata;
END test_type;2. Try to execute the above procedure using following Java code:-
public class TestType {
     public static void main(String[] args) throws Exception {
          java.sql.DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
          java.sql.Connection con = java.sql.DriverManager.getConnection(args[0],
                    args[1], args[2]);
          oracle.jdbc.driver.OracleCallableStatement stmt = (oracle.jdbc.driver.OracleCallableStatement) con
                    .prepareCall("call Test_Type.getVCTTData(?,?)");
           stmt.registerOutParameter(1, oracle.jdbc.driver.OracleTypes.ARRAY,
                    "test_type.avarchartabletype");
          stmt.registerOutParameter(2, oracle.jdbc.driver.OracleTypes.INTEGER);
          stmt.executeUpdate();
          // Get the ARRAY object and print the meta data assosiated with it
          oracle.sql.ARRAY simpleArray = stmt.getARRAY(1);
          System.out.println("SQLTypeName=" + simpleArray.getSQLTypeName());
          System.out.println("BaseType=" + simpleArray.getBaseType());
          System.out.println("length=" + simpleArray.length());
          String[] values = (String[]) simpleArray.getArray();
          for (int i = 0; i < values.length; i++) {
               System.out.println("row[" + i + "]=" + values[i] + "<BR>");
          stmt.close();
          con.close();
Result:
Exception in thread "main" java.sql.SQLException: invalid name pattern: test_type.avarchartabletype
     at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
     at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146)

     at oracle.sql.ArrayDescriptor.<init>(ArrayDescriptor.java:272)
     at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:196)
     at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:165)
     at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:150)
     at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:115)

     at oracle.jdbc.driver.OracleCallableStatement.registerOutParameter(OracleCallableStatement.java:179)
     at TestType.main(TestType.java:32)
This works fine when execute as PL/SQL using following snippet.
declare
  thepage   Test_Type.aVarCharTableType;
  irows     integer       := 10;
  cl        clob;
  begin
  Test_Type.getVCTTData(thepage, irows);
   for i in 1 .. irows
   loop
     cl := thepage (i);
     dbms_output.PUT_LINE(cl);
   end loop;
