我有这个gridview,我使用sqldatasource
这是我的select命令,
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:TAXIConnectionString %>"
SelectCommand="SELECT [TripId] FROM [BookingMaster]
WHERE(([PickupLocation] = @PickupLocation or @PickupLocation is null)
AND ([DestinationLocation] = @DestinationLocation
or @DestinationLocation is null )
AND ([Status] = @Status or @Status is null)
AND (cast([PickupDateTime] as date) = @PickupDateTime
or @PickupDateTime is null))"
CancelSelectOnNullParameter="False">
<SelectParameters>
<asp:ControlParameter ControlID="ddPickup" Name="PickupLocation"
PropertyName="SelectedValue" Type="String"
ConvertEmptyStringToNull="true" />
<asp:ControlParameter ControlID="ddDestination" Name="DestinationLocation"
PropertyName="SelectedValue" Type="String"
ConvertEmptyStringToNull="true" />
<asp:ControlParameter ControlID="ddStatus" Name="Status"
PropertyName="SelectedValue" Type="String"
ConvertEmptyStringToNull="true" />
<asp:ControlParameter ControlID="txtBookingDate" Name="PickupDateTime"
PropertyName="Text" Type="String" ConvertEmptyStringToNull="true" />
</SelectParameters>
</asp:SqlDataSource>
,但错误出现,因为我选择日期后13或其他…
Server Error in '/' Application.
Conversion failed when converting date and/or time from character string.
这有什么问题?
听起来像是本地化问题。我猜你输入日期的年月日格式,但ASP。NET或SQL Server试图用不变文化或en-US来解析它们,它期望使用mm/dd/yy格式。或者相反。当将日期传递给SQL Server时,最好已经使用DateTime.Parse
对它们进行了解析,或者使用yyyy-MM-dd HH:mm:ss
格式将它们作为字符串传递,这是完全明确的。
