问题描述
大家好,
这是我的存储过程:
Hi all,
This is my stored procedure:
USE [NCP]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[spTest]
(
@DateFrom datetime,
@DateTo datetime
)
as
begin
set nocount on
SELECT
FORMAT(convert(datetime,SCHEDULE_NEXT_DATE,104), 'yyyy-MM-dd HH:mm:ss') AS SCHEDULE_NEXT_DATE
FROM dbo.TestTable
WHERE
SAMPLE_TYPE = 'SampleSchedule'
AND SCHEDULE_NEXT_DATE BETWEEN @DateFrom AND @DateTo
end
我的TestTable列如下所示:
SCHEDULE_NEXT_DATE varchar(MAX) - 允许空值
当我选择前1000行时数据看起来像这样
SCHEDULE_NEXT_DATE
21-04-2015 10:30
21-04-2015 10:35
22-04-2015 10:30
22-04-2015 10:35
当我用sql profiler检查查询时,我没有得到任何结果。任何人都可以帮我解决这个疑问吗?
exec spTest @ DateFrom ='2015-04-21 10:30:00',@ DateTo ='2015-04- 21 10:35:00'
结果:0行
My TestTable column looks like this:
SCHEDULE_NEXT_DATE varchar(MAX) - Allow Nulls
Data looks like this when i select the top 1000 rows
SCHEDULE_NEXT_DATE
21-04-2015 10:30
21-04-2015 10:35
22-04-2015 10:30
22-04-2015 10:35
When i check the query with sql profiler i get no result. can anyone help me with this query?
exec spTest @DateFrom='2015-04-21 10:30:00',@DateTo='2015-04-21 10:35:00'
Result: 0 rows
推荐答案
WHERE
SAMPLE_TYPE = 'SampleSchedule'
AND
Convert(datetime, SCHEDULE_NEXT_DATE, 104) BETWEEN @DateFrom AND @DateTo
