I originally wrote this because I couldn't find a way to get the auto value, and the documentation for L2S was sparse at the time. Nice – I’ll have a try.

Simply navigate to your linq to sql(.dbml) file, click on the appropriate column and in the properties window set the "Auto Generated Value" to true. Now you dont have to spend time creating this function and calling it every time you want this to occur. It would be nice if you didnt even have to set "Auto Generated Value" property at all however.

If you use the code that Jay provided, the query will be ran separately, and the date will be passed as a parameter. Furthermore, it can't be used in precompiled queries! With the code provided by peteohanlon, linq will replace your GetSystemDate call in the linq query with GetDate in the resulting SQL query! And it can be used in precompiled queries :) It can also be used just to get the datetime though. In this case both are pretty much identical..

(VB) Private Function GetServerTime() as DateTime Dim result as IEnumerable(Of DateTime) = _ Me.ExecuteQuery(GetType(DateTime), _ "SELECT GETDATE() AS CurrentSQLDateTime", _ New Object() {}) Return result.Single End Function If so, any idea of the VB syntax for those bracketed attributes? Is there an advantage to this method over ExecuteQuery?
(VB)
Private Function GetServerTime() as DateTime
Dim result as IEnumerable(Of DateTime) = _
Me.ExecuteQuery(GetType(DateTime), _
“SELECT GETDATE() AS CurrentSQLDateTime”, _
New Object() {})
Return result.Single
End Function

If so, any idea of the VB syntax for those bracketed attributes?
