It seems the I was misunderstanding this help mailing list. I thought it's also
support for 'System.Data.SQLite'.
In the way 'System.Data.SQLite' is an ADO.NET provider for SQLite and also give
support for entity framework.
that because I was asking if it support

Hi,
how can I trunc time in EntityFramework?
I tried it this way:

.GroupBy(d => DbFunctions.TruncateTime(d.TimeStamp))
.Select(d => d.Key.Value)
.ToArray();
But get this error:

The 'T' devide the date from the time. Looking here

Oh sorry, i looked wrong. I insert this way:
INSERT INTO [filed1] VALUES '2011-01-01 08:00:00'
And because of the init of:
CREATE TABLE tabel1 (
[field1] time,
);
SQLite writes only the time to the database.
But this fails:
E() produces a string of the form '12:34:56' (hours:minutes:seconds).

NEW.TimeStamp is a complete datetime. But I only want to compare the time part
in my trigger.

No i think i can exclude this as the problem.
Because my code goes like this:
using (dataDBEntities context = new dataDBEntities())
//create context
{
using (TransactionScope transaction = new TransactionScope()) //begin
transaction
{
ta base are now 6 rows, that mean all after the failing insert are not
executed be the transaction.
So I think if I'm doing all right with checking out your fix, it is not working
at all. :(
