Parameters : the answer (3 replies)

Hello everybody,

I do not know exactly why this thread is closed :

Here is the answer :
The question mark that comes before the name of a parameter in a query is not part of the name of the parameter.

When I type this instruction :
cmd.Parameters.Add("?Username", MySqlDbType.VarChar, 255).Value = Username;

there is a mistake in it : no parameter name begins with a question mark.

Replacing the line by this will solve the problem :

cmd.Parameters.Add("Username", MySqlDbType.VarChar, 255).Value = Username;
