Solution 1

AddWithValue takes the actual value as second parameter, not the Type of the value. So, assuming the column "Newsales" is of Type Int32, this would be valid:

C#

int newsales = 1;
cmd.Parameters.AddWithValue("@two", newsales);

is my select sum function correct?

Yes - or to be more specific: What it will do is to produce the sum of all TotalPrice of those records in the table that have Newsales = @two . If that is what you want, then it's correct.
