c# - How to use OdbcParameter for MySQL?

How to use OdbcParameter for MySQL?

This is my current attempt:

command.Parameters.Add(new OdbcParameter("@username", username.Text));
command.Parameters.Add(new OdbcParameter("@password", password.Text));
command.CommandText = "INSERT INTO test.test (`user`,`password`) VALUES (@username,@password);";
command.ExecuteNonQuery();

but it seems to be not working. The database does create a new row, but it's values are NULL.

This works: (but I really need the parameters for other stuff)

command.CommandText = "INSERT INTO test.test (`user`,`password`) VALUES (`" + username.Text + "`,`" + password.Text + "`);";
command.ExecuteNonQuery();

What am I doing wrong?

Change your CommandText to be a valid one for OdbcCommand:

command.CommandText = "INSERT INTO test.test (`user`,`password`) VALUES (? , ?);";

Instead of the parameter name as @paramname, it takes a ? in the CommandText - leave the name in the actual parameters.

See this blog post for an example.
