Linq insert statement ...

[slen]

Dim db As New TableDataContext
db.GetTable(Of TableA).InsertOnSubmit(newItem)
db.SubmitChanges()

Linq executes this statement without any problem. But the things is it doesn't write to database ...

Does anyone knows the problem? Is there any setting I need to do ...

my server is MS SQL ..

executing from web service ...

Thanks
