sql server 2008存儲過程多選mybatis

我有一個關於存儲過程多選的問題在mybatis中。在stored_procedure.sqlsql server 2008存儲過程多選mybatis

USE cellar; 
GO 
alter PROCEDURE findAll_sp 
AS 
SELECT * FROM wine ORDER BY name; //The results of this select statement are stored in the list. 
SELECT * FROM wine where id=5; //The results of this select statement are not stored in the list. 
GO

stored_procedure.sql

只有一個SELECT語句的結果

兩個SELECT語句（先選擇一句）在stored_procedure.sql保存在WineDAO.java的列表。但是我想要列出所有這兩個select語句的結果。我該如何解決這個問題？

以下是相關的源代碼。

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> 
<mapper namespace="org.coenraets.cellar.cellar-mapper"> 
    <select id="findAll" resultType="Wine"> 
     {call findALL_sp} 
    </select> 
</mapper>

mapper.xml

public class WineDAO { 

    private static SqlSessionFactory ssf; 

    static{ 
     try{ 
      Reader reader= org.apache.ibatis.io.Resources.getResourceAsReader("Config.xml"); 
      ssf=new SqlSessionFactoryBuilder().build(reader); 
     }catch(Exception ex){ex.getMessage();} 
    } 

    public List<Wine> findAll() { 
     List<Wine> list = new ArrayList<Wine>(); 
     list = ssf.openSession().selectList("findAll"); 

     for(int i=0; i<list.size(); i++) 
     { 
      System.out.println(list.get(i).getName()); 
     } 

     return list; 
    } 
}

WineDAO.java

謝謝。

因爲它是一個存儲過程，所以你正在執行兩個語句，你的過程的結果將是最後一個，你不能同時檢索這兩個語句。在不同的查詢（不同的mybatis語句）中分隔兩個語句的查詢使用UNION。類似於'SELECT * FROM wine ORDER BY name UNION SELECT * FROM wine where id = 5' –

「你不能同時檢索」 - 不正確。查詢MARS –

謝謝你的回答，Jorge。許多存儲過程在我的項目中都有一個多選擇句子。所以在mybatis中沒有別的辦法，我要放棄mybatis。再次感謝。 –

我使用resultMap的解決了這個問題。謝謝:)
