I've always incorporated the at register the parameter title when utilizing AddWithValue, however i just observed some code compiled by another person that does not utilize it. Is an excellent method more correct compared to other?

cmd.Parameters.AddWithValue("ixCustomer", ixCustomer);


cmd.Parameters.AddWithValue("@ixCustomer", ixCustomer);

No, both of them are equivalent ultimately. Personally, i often make use of the notation using the @ sign myself, to become in conjuction with the T-SQL code for saved proc I write.

But so far as I understand, both techniques are acceptable for .Internet applications interfacing with SQL Server.
