在SQL Server 2005 Reporting Services 报表中格式化日期的方法可以 FormatDateTime的函数,下面是它的定义: Visual Basic (Declaration) Public Shared Function FormatDateTime ( _ Expression As DateTime, _ <OptionalAttribute> Optional NamedFormat As DateFormat = DateFormat.GeneralDate _ ) As String Visual Basic (Usage) Dim Expression As DateTime Dim NamedFormat As DateFormat Dim returnValue As String returnValue = Strings.FormatDateTime(Expression, NamedFormat)
下面是NamedFormat 的定义: Constant Description DateFormat.GeneralDate Display a date and/or time. Display a date part as a short date. If there is a time part, display it as a long time. If present, both parts display. DateFormat.LongDate Display a date using the long date format specified in your computer's regional settings. DateFormat.ShortDate Display a date using the short date format specified in your computer's regional settings. DateFormat.LongTime Display a time using the time format specified in your computer's regional settings. DateFormat.ShortTime Display a time using the 24-hour format (hh:mm).
它的类型就这么几种,很有限的,远远不能满足我们的需要。那怎么办?
实际上在报表中可以使用 ToString 的方法,来定义任意格式的字符串格式。比如: cdate(“2007-12-12 1:3:40”).ToString("yyyy-MM-dd") 可以格式化成 2007-12-12的格式,还可以格式化成12/12/2007这样的格式,甚至可以格式化成 2007+12+12这样的格式。这样只要你的format 格式化字符串正确,就可以实现你想要的日期格式。
