Parameterize SQL query

Question

Many posts about Parameters in SQL with C# but I am still missing something. I am not getting an error message but no data is inserted. What is missing? I have text boxes na

Answer 1

There are many ways of going about it. One of the ways is to replace the lines in the try block with:

comm.Parameters.AddWithValue("@first", first);
comm.Parameters.AddWithValue("@last", last);
comm.Parameters.AddWithValue("@addy", addy);
comm.Parameters.AddWithValue("@city1", city1);
comm.Parameters.AddWithValue("@stat", stat);
comm.Parameters.AddWithValue("@zippy", zippy);

If you do that, you dont need all the SqlParameter initializations

And you obviously need to execute the command:

comm.ExecuteNonQuery();
