Oracle编写带数组参数的存储过程

--功能：采用存储过程、type组合来实现批量操作，以节省系统开销，提高效率。  

      
      
--创建 Type bodies  
CREATE OR REPLACE TYPE TYPE_ARRAY AS OBJECT  
(  
  ID     NUMBER(10),  
  REMARK VARCHAR2(10)  
)  
--创建 Types  
CREATE OR REPLACE TYPE TYPE_ARRAY_TBL AS TABLE OF TYPE_ARRAY  
--创建表  
CREATE TABLE T_TEMP(ID NUMBER(10) NOT NULL, REMARK NUMBER(10))  
--创建存储过程  
 CREATE OR REPLACE PROCEDURE PROC_ARRAY_PARAM(TYPE_OBJECT IN TYPE_ARRAY_TBL) IS
     
 BEGIN
   INSERT INTO T_TEMP
     (ID, REMARK)
     SELECT ID, REMARK
       FROM THE (SELECT CAST(TYPE_OBJECT AS TYPE_ARRAY_TBL) FROM DUAL);
     
   FOR I IN 1 .. TYPE_OBJECT.COUNT LOOP
     DELETE FROM T_TEMP WHERE ID = TO_NUMBER(TYPE_OBJECT(I));
   END LOOP;
   COMMIT;
 END;
     
 END PROC_ARRAY_PARAM;


--创建包  
CREATE OR REPLACE PACKAGE PKG_PARAM AS  
  TYPE ARRAY_PARAMS IS TABLE OF VARCHAR2(20) INDEX BY BINARY_INTEGER; --先定义包，这个就相当于一个数组  
  PROCEDURE PROC_PARAM(PARAMS IN ARRAY_PARAMS);  
END PKG_PARAM;  
--创建包体  
CREATE OR REPLACE PACKAGE BODY PKG_PARAM AS  
  PROCEDURE PROC_PARAM(PARAMS IN ARRAY_PARAMS) AS  
    I NUMBER := 1; --这个可以不写  
  BEGIN  
    SAVEPOINT SP1;  
    FOR I IN 1 .. PARAMS.COUNT LOOP  
      DELETE FROM T_TEMP WHERE ID = TO_NUMBER(PARAMS(I));  
    END LOOP;  
    COMMIT;  
  EXCEPTION  
    WHEN OTHERS THEN  
      ROLLBACK TO SAVEPOINT SP1;  
  END PROC_PARAM;  
END PKG_PARAM;  

Java调用存储过程：

 package com.test.oracle;
 
 import java.sql.Connection;
 
 import java.sql.DriverManager;
 
 import java.sql.PreparedStatement;
 
 /** 调用存储过程 */
 public class ProcTest {
     
     public static void main(String[] args) {
 
         try {
 
             Class.forName("oracle.jdbc.driver.OracleDriver");
 
             String url = "jdbc:oracle:thin:@192.168.1.1:1521:orcl";
 
             Connection con = DriverManager.getConnection(url, "sys", "sys");
 
             PreparedStatement pstmt = null;
 
             String sql = "{call PROC_ARRAY_PARAM(?)}";
 
             pstmt = con.prepareCall(sql);
 
             Object[][] object1 = new Object[10][5];
 
             int max = 3615142;// 由于表有索引
 
             for (int i = 0; i < 10; i++) {
 
                 object1[i][0] = ++max;
 
                 object1[i][1] = 222;
 
                 object1[i][2] = 333;
 
                 object1[i][3] = 444;
 
                 object1[i][4] = 555;
 
             }
 
             oracle.sql.ArrayDescriptor desc = oracle.sql.ArrayDescriptor.createDescriptor("TYPE_ARRAY_TBL", con);
 
             oracle.sql.ARRAY array = new oracle.sql.ARRAY(desc, con, object1);
 
             pstmt.setArray(1, array);
 
             pstmt.executeUpdate();
 
         } catch (Exception e) {
 
             e.printStackTrace();
 
         }
 
     }
 }
