MyBatis：Sybase存儲過程返回零行

Question

我已經從此處復制了文本： http : //code.google.com/p/mybatis/issues/detail?id=164 ，但是我們遇到了同樣的問題。

MyBatis版本3.0.1

我將MyBatis 3用作Java應用程序和sybase數據庫之間的OR映射。 用於從數據庫中查詢數據的sql是存儲過程，對於簡單過程來說可以，但是如果在存儲過程中聲明並使用了內部變量，則似乎無法正常工作，查詢結果為null，而也不例外。

下面是示例代碼，我也附上了附件。 JavaBean：

    public class Test {

    private String input1;
    private String input2;

    public String getInput1() {
        return input1;
    }

    public void setInput1(String input1) {
        this.input1 = input1;
    }

    public String getInput2() {
        return input2;
    }

    public void setInput2(String input2) {
        this.input2 = input2;
    }
    }

sqlMap：

    <mapper namespace="cargoStatus_shipment">
    <resultMap id="testMap"     type="com.icil.esolution.cargoStatus.AS.model.Test">
    <result column="result1" jdbcType="VARCHAR" property="input1" />
    <result column="result2" jdbcType="VARCHAR" property="input2" />
    </resultMap>

    <select id="getValidData" statementType="CALLABLE"     resultMap="testMap"     parameterType="String">
     {call tempdb..testSP #{in}}
    </select> 

    </mapper>

存儲過程：

    use tempdb
    go
    drop proc testSP
    go
    create proc testSP
      @in varchar(10)

    as
     declare @var char(3)
     select @var="XXX"
     select result1= '1', result2=@in
    go
    grant exec on testSP  to public
    go

Java代碼：

public class TestSP {


  private static SqlSessionFactory createSqlMapper() throws IOException {
        String resource = "resources/sqlMapConfig.xml";
        Reader reader = Resources.getResourceAsReader(resource);
        return new SqlSessionFactoryBuilder().build(reader,"development");
  }


  public static void main(String[] args) {

    SqlSession session=null;
    try {
          session = createSqlMapper().openSession(ExecutorType.SIMPLE, true); //autocommit = true

    } catch (Exception e) {
       e.printStackTrace();
       System.out.println("Error in open Session. Cause: " + e);
       System.exit(1);
    }


    List result = (List) session.selectList("getValidData", "mydata"); 

    System.out.println("Result = "+result);
    System.out.println(result.get(2).getInput2());

  }

}

通常結果應該是：

DEBUG PreparedStatement - ==>  Executing: {call tempdb..testSP ?} 
DEBUG PreparedStatement - ==> Parameters: mydata(String)
DEBUG ResultSet - 

but actually, there is no result get, neither exceptions: DEBUG PreparedStatement - ==> Executing: {call tempdb..testSP ?} DEBUG PreparedStatement - ==> Parameters: mydata(String) after counter test, if i remove the inner variable @var from the sp, then it will be ok.

    use tempdb
    go
    drop proc testSP
    go
    create proc testSP
      @in varchar(10)

    as
     select result1= '1', result2=@in
    go
    grant exec on testSP  to public
    go

but actually, there is no result get, neither exceptions: DEBUG PreparedStatement - ==> Executing: {call tempdb..testSP ?} DEBUG PreparedStatement - ==> Parameters: mydata(String) after counter test, if i remove the inner variable @var from the sp, then it will be ok.

 use tempdb go drop proc testSP go create proc testSP @in varchar(10) as select result1= '1', result2=@in go grant exec on testSP to public go 

您能否檢查出問題所在，該怎么辦以確保可以調用這種存儲過程？

我想為以上帖子修改一個錯字。

通常結果應該是：
DEBUG PreparedStatement - ==> Executing: {call tempdb..testSP ?}
DEBUG PreparedStatement - ==> Parameters: mydata(String)
DEBUG ResultSet - <== Columns: result1, result2
DEBUG ResultSet - <== Row: 1, mydata
