本文介绍如何使用ODAC11.2.0.3.0与OracleDeveloperToolsforVisualStudio进行本地安装并提取7个DLL。通过新建项目连接Oracle数据库，展示在其他机器上打包安装测试成功的过程，并探讨了最大DLL文件无法删除的问题。同时，介绍了如何在Oracle数据库中创建和调用存储过程的传统数组，实现数据操作。

ODAC 11.2.0.3.0 with Oracle Developer Tools for Visual Studio
安装本机为了提取7个DLL

新建项目

连接字符串代码：

        private void Button_Open_Click(object sender, EventArgs e)
        {

            string tns = "(DESCRIPTION =";
    tns+="(ADDRESS_LIST =";
      tns+="(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.98.87)(PORT = 1521)))";
    
    tns+="(CONNECT_DATA =(SERVICE_NAME = TestDev) )  )";
      
   
            string CON = "Data Source="+tns+";User Id=APPS;Password=123456;"; 
 ;

         try
         {
             using (OracleConnection conn = new OracleConnection(CON))
             { 

                 conn.Open();
                 MessageBox.Show("Open");

             }
         }
         catch(Exception ex)
         {
             MessageBox.Show(ex.Message);
         }

        }

在其他机器上打包安装测试成功，做了个实验最大的那个DLL不能删除

Oracle存储过程传统数组

  /**

  type  myList is table of varchar2(32767) INDEX BY BINARY_INTEGER;
   
  TYPE DAY_ARRAY_TYPE IS VARRAY(3) OF VARCHAR2(2);

  procedure list(ilist in number_list);
end;
            create or replace package body Pkg_Test is

  procedure list(ilist in myList) as
  
  begin
  
    for i in 1 .. ilist.count loop
    
      insert into apps.test (id) values (ilist(i));
    end loop;
    commit;
  exception
    when others then
      rollback;
  end;
end;

             */
