将字符串转换为MS Access查询中的日期
我试图从我的访问表中检索数据基于日期列,要求是显示大于某个值的一切
I am tyring to retrieve data from my access table based on Date column, requirement is to display everything greater than certain value
我试图强制转换我的值是使用Format&
I am trying to cast my value which is a string using Format & CDate function with date time type, it throws out as Overflow.
这里是查询:
Select * from Events
Where Events.[Date] > cDate(Format("20130423014854","yyyy-MM-dd hh:mm:ss"))
示例日期记录值来自表:2013-04-23 13:48:54.0
Sample Date Record Value from Table : 2013-04-23 13:48:54.0
事件。[Date]是访问中的日期/时间类型字段
Events.[Date] is a Date/Time type field in access
如何解决这个问题?
$ c>创建>模块并粘贴以下代码
In Access, click Create > Module
and paste in the following code
Public Function ConvertMyStringToDateTime(strIn As String) As Date
ConvertMyStringToDateTime = CDate( _
Mid(strIn, 1, 4) & "-" & Mid(strIn, 5, 2) & "-" & Mid(strIn, 7, 2) & " " & _
Mid(strIn, 9, 2) & ":" & Mid(strIn, 11, 2) & ":" & Mid(strIn, 13, 2))
End Function
点击 Ctrl + kbd>并将模块保存为 modDateConversion
。
现在尝试使用像
Select * from Events
Where Events.[Date] > ConvertMyStringToDateTime("20130423014854")

避免用户定义的VBA函数的备选解决方案:
Alternative solution avoiding user-defined VBA function:
SELECT * FROM Events
WHERE Format(Events.[Date],'yyyyMMddHhNnSs') > '20130423014854'
