BASH problem with IFS within nested while loops reading from MySQL

I am having a problem with my bash script -- And I think honestly it's a matter of understanding IFS completely.

I have read multiple questions on SO but seem to be going in circles I think because none address the issue specifically having to do with MySQL ... But I'll defer to your expertise on that. First here is the script I am having trouble with:

#!/bin/bash

mysql --login-path=main-data -Nse "SELECT b.name, a.section_id
FROM some_table" | while read section_name section_id; do

echo "$section_name - $section_id"

    mysql --login-path=main-data -Nse "SELECT a.page_id, b.page_url
                FROM some_table" | while read page_id page_url; do
                echo "    - $page_url";
    done

 get_children() {
        mysql --login-path=main-data -Nse " SELECT b.sections_id, b.name
        FROM some_table" | while read child_id section_name; do
            echo "  -- $section_name";
            # If statement goes here -- Then recursive
            if [[ $child_id = *[!\ ]* ]]; then
            section_id=$child_id

            # Now get pages for child sections
            mysql --login-path=main-data -Nse "SELECT page_id, page_url
            FROM some_table" | while read page_id page_url; do
                echo "        - $page_url";
            done

            get_children $section_id
            fi

        done
    }

    get_children $section_id

done

If I run my script without IFS as-is the output looks like:

HOME - 732
    - Home.htm
    - Home2.htm
    - Nome3.htm
WHY - US        742
ROOFING - 743
    - Residential-Roofing.htm
  -- Certainteed
        - CertOverview.htm

The issue comes with "WHY US" -- If you notice the dash ended up in the wrong spot -- Obviously a delimiter issue because there is a space there .. Now if I change the first loop to :

mysql --login-path=main-data -Nse "SELECT a.page_id, b.page_url
FROM some_table" | while IFS='\n' read page_id page_url; do

My output becomes :

HOME    732 - 
WHY US  742 - 
ROOFING 743 - 

Which you'll notice the dashes are ALL in the wrong spot but "WHY US" has the correct space in it. In addition to that my nested loops did not run. I am thoroughly confused about the "correct" way to deal with spaces in these names, and still get the desired nested output! Where am I going wrong?

SO QUESTION Again same issue ... Obviously I tried what they have in the answer section to no avail.
