將varchar值'7:00'轉換爲數據類型int轉換失敗int

Question

我無法計算如何轉換此時間。我看到了如何轉換其他值但不是時間的其他方法。誰能幫助謝謝。

select count(*) 
from reporting_call_matrix AS A WITH (NOLOCK) 
Where CALENDAR_DATE Between '10/1/2015' and '10/31/2016' and Call_hour Between '7:00' and '19:00' 

Answer 1

根據錯誤消息，call_hour將顯示爲整數。所以，試試這個：

select count(*) 
from reporting_call_matrix AS A WITH (NOLOCK) 
Where CALENDAR_DATE Between '2015-10-01' and '2016-10-31' and 
     Call_hour Between 7 and 19; 

我強烈建議你爲日期常量使用ISO標準日期格式。
