在java語言中調用儲存過程

今天寫的這個是在java語言中調用oracle的儲存過程，

首先先建一個儲存過程

Createor replace procedure selectemp(eid number,empname out varchar,empsal outnumber)

As

begin

Selectename,sal into empname,empsal from emp where empno=eid;

End;

然後是java程序

importjava.sql.CallableStatement;

importjava.sql.Connection;

importjava.sql.DriverManager;

importjava.sql.ResultSet;

importjava.sql.SQLException;

 

importoracle.jdbc.OracleCallableStatement;

 

publicclass TestOracle {

 

   private static Connection conn;

 

   static {

      try {

        // 第一步：加載驅動

        Class.forName("oracle.jdbc.driver.OracleDriver");

        // 得到連接對象

        conn = DriverManager.getConnection(

              "jdbc:oracle:thin:@localhost:1521:orcl","test", "test");

      } catch (ClassNotFoundException e) {

        // TODO Auto-generated catch block

        e.printStackTrace();

      } catch (SQLException e) {

        // TODO Auto-generated catch block

        e.printStackTrace();

      }

 

   }

 

  

   public static void main(String[] args) throwsSQLException {

 

      // 參數 in out參數 通過站位符號

      CallableStatement cas = conn.prepareCall("{callselectemp(?,?,?)}");

      // 從1開始

      int index = 1;

      // 爲佔位符賦值

      cas.setInt(index++, 7369);

      // 輸出參數

      cas.registerOutParameter(index++, oracle.jdbc.OracleTypes.VARCHAR);

      cas.registerOutParameter(index++,oracle.jdbc.OracleTypes.NUMBER);

 

      // 執行操作 Resulset rs rs true |false

      boolean flag = cas.execute();

      // 判斷

      if (!flag) {

        String name = cas.getString(2);

  

        int sal = cas.getInt(3);

       

        System.out.println(name);

     

        System.out.println(sal);

     

      }

 

   }
