Drupal 7.x

I have planned to secure the data by encrypting the entire database using Transparent Data Encryption(TDE).

I have done the same encryption in MSSQL server with .NET its works fine.

But am not sure, is that possible with Drupal and its impact. Can anyone suggest me?

I've built a small, barebones site for a local prayer group, using the Open Outreach distro of Drupal 7, and I want to re-arrange the blocks in the sidebar-second region so that the announcement of the next meeting time and place is at the top. The problem I've run into is that I can't move the user login blocks. When I clicked on it to edit it, it said it wasn't assigned to a region. I tried assigning the login block to the leaderboard region, and the result was that the login block now appeared in both sidebar-second and leaderboard.

I know D8 has a useful ability to hide fields on the "manage form display" tab, without actually deleting the field and losing its data. 

I'm curious if there's any comparable solution in D7 (without just cheating and adding CSS to display:none.) 

Firstly, a few housekeeping items:
- I am new to Drupal.
- Explanations are greatly appreciated.
- I am using Drupal 7.59 due to working with a pre-existing install.
- The only module I have installed is the PHP filter.

I've spent two days researching, educating myself, and trialling numerous example codes and before deciding to post.

The goal:
To insert data into a custom table in the database created by the Drupal install.

The problem:
Upon previewing the following example code, I am met with an 404 error:

I have two content type Story and Chapter in a book structure like:

- Story A
+++ Chapter a1 (post: 3/10/14)
+++ Chapter a2 (post: 3/11/14)

- Story B
+++ Chapter b1 (post: 3/20/14)
+++ Chapter b2 (post: 3/21/14)
+++ Chapter b3 (post: 3/22/14)

Now, I want a View to list Story pages in order of recent posted Chapter pages, like:

- Story B: Chapter b3 (3/22/14)
- Story A: Chapter a2 (3/11/14)

How can I make it?
