Question

Hi
I am getting an error
‘Conversion failed when converting date and/or time from character string’
When calling a stored procedure using EF4.

I am passing from my c# 2 DateTimes like this

@FromDate=’2010-11-10 12:30:14.2558729′
@ToDate= ‘2010-11-10 12:30:15.1169590’

How can I prevent this error?

if I do the following in my UI it works

FromDate = new DateTime   (SelectedFromDate.Year,SelectedFromDate.Month,SelectedFromDate.Day),
ToDate = new DateTime(SelectedToDate.Year, SelectedToDate.Month, SelectedToDate.Day),

Thanks for any suggestions

Answer 1

Reduce the number of digits on the fractional seconds to three. Try it out…

What you are trying to do:

select convert(datetime,'2010-11-10 12:30:14.2558729')
--                                           ^^^^^^^

OUTPUT:

-----------------------
Msg 241, Level 16, State 1, Line 1
Conversion failed when converting datetime from character string.

Using only 3 decimal digits:

select convert(datetime,'2010-11-10 12:30:14.255')
--                                           ^^^

OUTPUT:

-----------------------
2010-11-10 12:30:14.257
