    What value? What table? You need to provide some more details about your problem.

            Aight, first you'd need a Sql-statement to select the value you're interested in. Something like this

            SELECT [connType]
            FROM [Login]
            WHERE [Id] = @Id

                  :confused::confused::confused::confused: if the user is logged in as you say, you must already have read the table to identify him, so you already know how to obtain data from a table.
