视图中的SQL转换错误

Question

我在视图中尝试以下SQL查询

select 
    ShiftDate, empid, firstin, lastout, totalhrsfilo 
from 
    [View_Name] 
where 
    [ShiftDate] between '2016-06-01' and '2016-06-30' 
    and empid in (1, 2, 3, 4, 5, 6, 7, 8) 
    and remarks != 'Weekly Off 1' 
    and remarks != 'Weekly Off 2'

我收到此错误：

  

将nvarchar值'External'转换为数据类型int时转换失败。

从此错误中，我无法确定转换错误发生在哪一列。

查看结构：

如何查找哪个列会产生错误以及如何解决？

Answer 1

我认为您的问题与此类似：Conversion failed when converting the nvarchar value ... to data type int

select ShiftDate,empid,firstin,lastout,totalhrsfilo from [View_Name] where [ShiftDate] between '2016-06-01' and '2016-06-30' and Convert(int,empid) in (1,2,3,4,5,6,7,8) and remarks!='Weekly Off 1' and remarks!='Weekly Off 2'

如果这不起作用，请发布您的视图结构，以便我们深入挖掘。

Answer 2

我的问题得到了答案。

select ShiftDate,empid,firstin,lastout,totalhrsfilo from [View_Name] where [ShiftDate] between '2016-06-01' and '2016-06-30' and empid in ('1','2','3','4','5','6','7','8') and remarks!='Weekly Off 1' and remarks!='Weekly Off 2'

Empid是varchar字段;改变以下条件后的工作

empid in ('1','2','3','4','5','6','7','8')
