Data type mismatch in criteria expression | Access, OleDb, C#

Question

I read/update data from MS Access using C#. My code is:

public static void UpdateLastLogin(int userid, DateTime logintime) ///logintime = DateTime.Now
{
             


        

Answer 1

Firstly, no your SQL statement should be:

"UPDATE Customers SET LastLogin=@LastLogin"

Secondly, the reason you are receiving the date mismatch error will probably be your passing '?' as your date time into the LastLogin field instead of the actual logintime parameter.
