Script example

In the script for capturing form input on page 120, the variable for capturing the last name has not been declared in the Razor script.
It is also not listed in the body under the "You entered" section, even though it is specified in the form input fields.

Step 1, first sentence

The first sentence of Step 1 currently mentions the file name "input.cshtml" but it should instead mention the file name "index.cshtml".

Code sample in Step 5

The code "7-1.sdf" should read "7.1" without the ".sdf".

Code

Why when I run the index.cshtml I can't have the same result as in figure 7-12? Mine comes out blank? Can I have an explaination?

Regards

codes

var db = Database.Open("7-1"); instead var db = Database.OpenFile("7-1"); and somewhere, it should have been said to put this:(
var updateQ = "UPDATE TwitterFriends SET FirstName=@0, LastName=@1, TwitterID=@2 WHERE id=@3";) on one line to avoid any error message.

Code sample, updateQ variable declaration

The SQL statement in the updateQ variable declaration should capitalize "Where" so that it reads "WHERE"

Code and alternative

I think it would be really awesome if the (edit.cshtml) file had code that allow real sorting for if the db is a large one. Or if I want to target names beginning with certains letters, wha do I do?

Code example

In the code you find:
if (eMailSubject==null) {}
This raises an error. It should be: if (eMailSubject.IsEmpty()){}
The same for the other examples on the page.

Step 2

In Step #2 in "Adding Data to the Database," it is unclear what actions the reader is supposed to perform. The directions are to "Open the database, and then call the Execute method on the database...." However, this seems more like a description of what the code is doing, rather than an instruction for the user to perform. Fortunately, if you skip this step, you can still complete the procedure successfully.

Code samples, SQLUPDATE variable declaration

In the "var SQLSELECT" statement, some of the words should have the case inverted. Instead of "where ID=@0" it should read "WHERE id=@0"
