7:23 a.m.
hi all,
i have to migrate an application from postgres to mssqlserver2005.
it went quite well, until so far, but now i'm blocked for a while.
When user enter my application, a row is written to a table "Sessions(id int, user
int, startTime datetime)".
(the id is auto-generated by the database).
I see the row is correctly written in the database, but when i want to retrieve the id
that the database generated,
the application crashes:

However, I think I changed everything correctly:
