Question

String dateString = null;
SimpleDateFormat sd = new SimpleDateFormat("yyyy/MM/dd");
dateString = sd.format(pumpTime);

PreparedStatement st = con.prepareStatement("{call dbo.HrMin(?,?)}");   st.setString(1,dateString);      
st.setInt(2,7);   
ResultSet rs = st.executeQuery();    while(rs.next())  {}  

procedure is :
USE [NC26]
GO

/****** Object:  StoredProcedure [dbo].[HrMin]    Script Date: 03/29/2016 15:40:56 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

)

-- insert the survey table structures for use

insert into #finalresults (hr, val)
Select distinct hr,(Select top 1 val from hrtableView where tagindex=@tagindex 
and dt=@date and hr=t1.hr ) from hrtableView t1 where tagindex =@tagindex
and dt=@date  group by hr;


insert into #finalresults (hr, val)
Select distinct hr,(Select top 1 val from hrtableView1 where tagindex=@tagindex 
and dt=@date and hr=t1.hr ) from hrtableView1 t1 where tagindex =@tagindex
and dt=@date  group by hr;

SELECT hr,val FROM #finalresults
drop table #finalresults

END

GO

error: The statement did not return a result set.

我使用了可调用语句，但是出现了同样的错误。我曾经使用过谷歌的这么多技巧，但一次又一次地犯了同样的错误。

Answer 1

在程序中按SET NOCOUNT将解决错误
