摘要：java调用Oracle存储过程的方法实例

[b]1.测试添加数据的procedure [/b]

public void testProcedure() {
        Connection con = getConnction();
        // **1.测试添加数据的procedure
          String procedure = "{call users_insert_proc(?,?,?,?) }";

        CallableStatement cs = null;
        try {
             cs = con.prepareCall(procedure);
             cs.setInt(1, 123450);
             cs.setString(2, "xxiaox");
             cs.setString(3, "Ww342864");
             cs.setString(4, "742621646@qq.com");
             } catch (SQLException e) {
              e.printStackTrace();
        }
        try {
             cs.executeUpdate();
        } catch (SQLException e) {
               e.printStackTrace();
        }
    }

[b]2.测试删除数据的procedure[/b]

[u]复制代码[/u] 代码如下:

public void testDelPro() {
        Connection con = getConnction();
        // **2.测试删除数据的procedure
         String procedure = "{call delete_usersbyid_proc(?) }";

        CallableStatement cs = null;
        try {
             cs = con.prepareCall(procedure);
                      cs.setInt(1, 123450);
             } catch (SQLException e) {
              e.printStackTrace();
        }
        try {
             cs.executeUpdate();
        } catch (SQLException e) {
               e.printStackTrace();
        }
    }

[b]3.测试更新数据的procedure[/b]

[u]复制代码[/u] 代码如下:

public void testDelPro() {
        Connection con = getConnction();
        // **3.测试更新数据的procedure
        String procedure = "{call users_updatebyId_proc(?,?,?,?) }";

        CallableStatement cs = null;
        try {
             cs = con.prepareCall(procedure);
         cs.setInt(1, 101);          cs.setString(2, "小第三方的浩");          cs.setString(3, "asdf342864");         cs.setString(4, "742621646@qq.com");
             } catch (SQLException e) {
              e.printStackTrace();
        }
        try {
             cs.executeUpdate();
        } catch (SQLException e) {
               e.printStackTrace();
        }
    }

[b]4.测试查找数据的procedure[/b] a)建包体 b)创建查询的procedure

[u]复制代码[/u] 代码如下:

create or replace package userspackage as
type users_cursor is ref cursor;
end  userspackage;

[u]复制代码[/u] 代码如下:

create or replace procedure users_packageAll(
s_id in number ,u_cursor out userspackage.users_cursor) is
begin
   if s_id = 0 then
       open u_cursor for select id,name,pword,email  from users;
      else
       open u_cursor for select id,name,pword,email  from users where id=s_id;
      end if;
  end;

c)Java调用

[u]复制代码[/u] 代码如下:

public void testDelPro() {
        Connection con = getConnction();
        // 返回查询procedure
       String procedure = "{call users_packageAll(?,?) }";
        CallableStatement cs = null;
        try {
             cs = con.prepareCall(procedure);
                     cs.setInt(1, 0);
     cs.registerOutParameter(2, oracle.jdbc.OracleTypes.CURSOR);

             } catch (SQLException e) {
              e.printStackTrace();
        }
        try {
             cs.execute();
              ResultSet rs = (ResultSet)cs.getObject(2);
            while (rs.next()) {
              System.out.println(rs.getInt(1) + " " + rs.getString(2));
            }
        } catch (SQLException e) {
               e.printStackTrace();
        }
    }
