java如何将一个List传入Oracle存储过程

注：本文来源于  深圳gg  《 java如何将一个List传入Oracle存储过程   》

 

一：数据库端建一个PL/SQL的数组。

CREATE OR REPLACE TYPE tables_array AS VARRAY(100) OF VARCHAR2(32) ;

drop table test purge;
create table test
(
  name varchar2(32)
);


create or replace procedure t_list_to_p(arr_t in tables_array) is
begin
  for i in arr_t.first .. arr_t.last loop
    insert  into test values(arr_t(i));
  end loop;
  commit;
end t_list_to_p;

 

二：java代码：

 import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;


public class TestListToProcedure {
    static final String driver_class  = "oracle.jdbc.driver.OracleDriver";
    static final String connectionURL = "jdbc:oracle:thin:@10.150.15.150:1521:orcl";
    static final String userID        = "test";
    static final String userPassword  = "test";
    public void runTest() {
        Connection  con = null;
        CallableStatement stmt = null ;
        try {
            Class.forName (driver_class).newInstance();
            con = DriverManager.getConnection(connectionURL, userID, userPassword);
            stmt = con.prepareCall("{call t_list_to_p(?)}");
            ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("TABLES_ARRAY",con);
            List list = new ArrayList();
            list.add("张三");
            list.add("李四");
            list.add("王五");
            ARRAY array = new ARRAY(descriptor,con,list.toArray());
            stmt.setArray(1, array);
            stmt.execute();
        }  catch (SQLException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }finally{
        	if(stmt != null){
        		try {
					stmt.close();
				} catch (SQLException e) {
					e.printStackTrace();
				}
        	}
        	if(con != null){
        		try {
        			con.close();
				} catch (SQLException e) {
					e.printStackTrace();
				}
        	}
        }
    }

    public static void main(String[] args) {
    	TestListToProcedure testListToProcedure = new TestListToProcedure();
    	testListToProcedure.runTest();
    }

}
