Solution 1

Maybe you must delete ToLongTimeString() in

XML

DateTime.Now.ToLongTimeString()

into

XML

DateTime.Now()

because you data type column inTime is smalldatetime, you can't use ToLongTimeString()

Why????

Why are you issuing this kind of statement directly in Entity Framework? Is there no entity in the model you can address? Than why are you using EF on the first hand?

But if you stick to this approach, have a look here: http://www.inforbiro.com/blog-eng/entity-framework-how-to-use-datetime-in-esql-query/[^]

You have an other option though: if you want to execute something outside the context, you can extract the ADO connection string from it, and use regular ADO approach for that. Have a look here: http://stackoverflow.com/questions/13003797/get-the-entity-framework-connection-string[^]

I figured it out, but why are you issuing this insert statement as raw sql - why not with EF via the entity model? Please read the linked pages also!
