jdbc調用mysql存儲過程實現代碼帶有輸入和輸出

轉載自 http://www.jb51.net/article/34747.htm

1. 創建存儲過程 
建立一個MySQL的存儲過程 add_pro 

復制代碼代碼如下:

delimiter // 
drop procedure add_pro // 
create procedure add_pro(a int , b int , out sum int ) 
begin 
set sum = a * b; 
end; 
// 

2. 調用存儲過程 

復制代碼代碼如下:

package com.zhanggaosong; 
import java.sql.CallableStatement; 
import java.sql.Connection; 
import java.sql.DriverManager; 
import java.sql.Types; 
public class CallableStatementTest { 
public static final String DRIVER_CLASS = "com.mysql.jdbc.Driver"; 
public static final String URL = "jdbc:mysql://127.0.0.1:3306/test"; 
public static final String USERNAME = "root"; 
public static final String PASSWORD = "123456"; 
public static void main(String[] args) throws Exception { 
Class.forName(DRIVER_CLASS); 
Connection connection = DriverManager.getConnection(URL, USERNAME, 
PASSWORD); 
String sql = "{CALL add_pro(?,?,?)}"; //調用存儲過程 
CallableStatement cstm = connection.prepareCall(sql); //實例化對象cstm 
cstm.setInt(1, 122); 
cstm.setInt(2, 2); // 
cstm.registerOutParameter(3, Types.INTEGER); // 設置返回值類型 
cstm.execute(); // 執行存儲過程 
System.out.println(cstm.getInt(3)); 
cstm.close(); 
connection.close(); 
} 
}
