java - 将对象类型表从 java 传递到 oracle 8i

Question

我需要将对象列表（如值表）从 java 传递到 oracle 8i。

我正在尝试使用 oracle 8i 中的以下数据库对象。

这在 8i 中可能吗？
如果可能，请帮助我解决问题。

create or replace type GROUP_OBJ as object    (          

 GROUP_TYPE VARCHAR2(32), 
 PARAM_1 VARCHAR2(16), 
 PARAM_2 VARCHAR2(16)
);
/


CREATE OR REPLACE
TYPE GROUP_table AS TABLE OF GROUP_OBJ; 
/

CREATE OR REPLACE PROCEDURE GROUP_TABLE_TEST (TABLE_OBJ IN GROUP_table)
IS

BEGIN
    null;
EXCEPTION
   WHEN OTHERS
   THEN
      ROLLBACK;
END GROUP_TABLE_TEST;

Answer 1

我得到了答案。由于区分大小写的问题，我遇到了麻烦。传递给 Structdescriptor 和 arraydescriptor 的类型名称区分大小写。当为两者都提供大写时，它起作用了。

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.SQLException;

import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
import oracle.sql.STRUCT;
import oracle.sql.StructDescriptor;

public class PassTableOfObject {

      public static void main(String[] args) throws SQLException {
         Connection conn=FucntionTest.getConnection();

            try{

                StructDescriptor itemDescriptor = StructDescriptor
                        .createDescriptor("GROUP_OBJ", conn);

                STRUCT[] structs = new STRUCT[2];
                for (int index = 0; index < 2; index++)
                {

                    String[] params = new String[2];
                    params[0] = "Group "+index;
                    params[1] = "Param  1 "+index;
                    STRUCT struct = new STRUCT(itemDescriptor, conn, params);
                    structs[index] = struct;
                }

                ArrayDescriptor desc = ArrayDescriptor.createDescriptor("GROUP_TABLE", conn);
                ARRAY oracleArray = new ARRAY(desc, conn, structs);



                CallableStatement cs = null;
                cs = conn.prepareCall("{call GROUP_TABLE_TEST(?)}");
                cs.setArray(1, oracleArray);
                cs.execute();
                conn.commit();


                System.out.println("insert procedure executed successfully");                  

                }catch(SQLException e){
                    e.printStackTrace();        
                }finally{
                    conn.close();
                }
      }
}
