Hi,
I'm facing an issue with date culture conversion (probably), but I don't know if i'm not seeing the obvious or...
In my SqlDataProvider I have two Sub-s - one for adding data and the other one for updating. The calls are:

    SqlHelper.ExecuteNonQuery(ConnectionString, GetFullyQualifiedName("mySprocAdd"), DateFrom, DateTo, Description)
and
    SqlHelper.ExecuteNonQuery(ConnectionString, GetFullyQualifiedName("mySprocUpd"), ID, DateFrom, DateTo, Description)

The adding works fine, the update des not. So, the date format in Croatia is dd.mm.yyyy and the format in DNN for hr-HR is dd.mm.yyyy. (notice the dot in the end of the year part). So, when i execute the sproc through SQL Management Console with the parameters from DNN it returns an error for the date formatting. When I remove the dot behind the year everything works fine. What I don't understand is why the adding records through DNN works fine and the updating not? I'm not doing any format changes anywhere in the code.

Any ideas anyone.

Thanks

..me again.

now, for testing purposes, I've tried sending the date to the sproc as a string and in the sproc convert it again to smalldatetime format.

So, I'm sending this
    Dim localDateFrom As String = Format(DateFrom, "yyyy-mm-dd hh:mm")

The sproc looks like
...
UPDATE [dbo].[myTable]
   SET [DateFrom] = Convert(smalldatetime, @DateFrom,20) ,[DateTo] = Convert(smalldatetime, @DateTo,20)
  ....

And the error I'm getting is:

DefaultDataProvider: DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider
ExceptionGUID: c6cb54d0-0184-4917-9904-03c8c3b185db
InnerException: Conversion failed when converting character string to smalldatetime data type.
FileName:
FileLineNumber: 0
FileColumnNumber: 0
Method: System.Data.SqlClient.SqlConnection.


The problem is not in the SQL server as when you try this:

Declare @SQLQuery AS nvarchar(max)
set @SQLQuery ='2011-11-17 16:20'
print convert(smalldatetime,@SQLQuery ,20)

You will get

Nov 17 2011 4:20PM

I'm just stuck here. No more ideas.

well, after some debuging (and peeking to others code) I've started to use the DateTime format instead of Date in vb and smalldatetime in sql server and now everything works.

Maybe thie experience will help someone...
