/*
   This program demonstrates how to emulate calling a stored procedure
   with PL/SQL table parameters via JDBC.  You cannot call a PL/SQL table
   parameter directly, but you can use an Object of Type Table.

   The Script used to create the procedure used in this example is as
   follows:

   create or replace type tabtype as table of varchar2(30);
   /

   create or replace package ioArray as

   procedure testproc(iotab in out tabtype,otab out tabtype);

   end ioArray;
   /

   create or replace package body ioArray as

   procedure testproc(iotab in out tabtype,otab out tabtype) is
   begin
      otab := iotab;
      if iotab.count = 0 then
         iotab.extend;
         iotab(1) := 'Record 1';
      else
         iotab.extend;
         iotab(iotab.count) := 'Second'||iotab(1);
      end if;
   end testproc;
   end ioArray;
   /
*/
   public static void main(String[] args) throws SQLException {
      DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());

    // Connect to the database

      Connection conn =
         DriverManager.getConnection ("jdbc:oracle:oci8:@S692815.WORLD",
                                   "scott", "tiger");

   //  First, declare the data arrays that will store the data.

      String [] p1obj = {"First"};
      String [] p2obj = {};

   //  Now, declare a descriptor to associate the host array type with the
   //  array type in the database.

      ArrayDescriptor desc1=ArrayDescriptor.createDescriptor("TABTYPE",conn);

   //  Create the ARRAY objects to associate the host array
   //  with the database array.

      ARRAY p1arr = new ARRAY(desc1,conn,p1obj);
      ARRAY p2arr = new ARRAY(desc1,conn,p2obj);

   //  Declare the callable statement.
   //  This must be of type OracleCallableStatement to use:
   //     setArray(ARRAY)
   //         and
   //     registerOutParameter(position,type,oracletype)

      OracleCallableStatement ocs =
         (OracleCallableStatement)conn.prepareCall("{call ioarray.testproc(?,?)}");

   //  The first parameter is in out, so you must use setArray to
   //  pass it to the statement.

      ocs.setArray(1,p1arr);

   //  The first parameter is in out, so you must Register the parameter as
   //  well.
   //  Note the reuse of the TYPE.

      ocs.registerOutParameter(1,OracleTypes.ARRAY,"TABTYPE");

  //   The second parameter is out, so that must be registered too.
  //   Note the reuse of the TYPE.

      ocs.registerOutParameter(2,OracleTypes.ARRAY,"TABTYPE");

   //  Execute the procedure

      ocs.execute();

   //  Associate the returned arrays with the ARRAY objects.

      p1arr = (ARRAY)ocs.getArray(1);
      p2arr = (ARRAY)ocs.getArray(2);

   //  Get the data back into the data arrays.

      p1obj = (String[])p1arr.getArray();
      p2obj = (String[])p2arr.getArray();

   //  Show the results:

      System.out.println("p1obj[p1obj.length-1] is " + p1obj[p1obj.length-1]);
      System.out.println("p2obj[0] is " + p2obj[0]);
