I\'m using Microsoft Access unfortunately because of higher forces and trying to update a record with no luck.

This is the code:

Answer 1

You need ? for the place holder and the parameters must be added in the order in which they occur: http://msdn.microsoft.com/en-us/library/dw70f090.aspx

Answer 2

try

string query = "UPDATE [Contact] SET [FirstName] = ? [LastName] = ?, [MobileNumber] = ? WHERE [Id] = ?"

Add your parameters in the order of the statement, i.e. firstname...id
