Hope this helps The problem is you are creating the PDF file in the while loop, I don't think you want 52k PDF files, so you should create the PDF file first, then loop through all of the results and paste them into the file.
EDIT: I would suggest adding line to insert/update PDF to database after
code :
NewDoc.Close();

seems to work fine Yes that's correct behavior since you are actually trying to merge multiple column values in single column which is not possible
code :
( SELECT c.name AS Company,
CONCAT(UPPER(u.forename),' ', u.surname) AS Username,
count(c.case) AS 'No. of Private Cases Generated',
) AS 'No. of Private Cases Generated',
SELECT c.name AS Company,
CONCAT(UPPER(u.forename),' ', u.surname) AS Username,
count(c.case) AS 'No. of Private Cases Generated'
FROM some_table  --first part of query

UNION            -- combine the data

SELECT c.name AS Company,
CONCAT(UPPER(u.forename),' ', u.surname) AS Username,
count(c.case) AS 'No. of Web Cases Generated'
FROM some_other_table;  -- second part of query
select xx.Company, xx.Username,xx.'No. of Private Cases Generated',
xxx.Company1, xxx.Username1, xxx.'No. of Web Cases Generated'
FROM (
SELECT c.name AS Company,
CONCAT(UPPER(u.forename),' ', u.surname) AS Username,
count(c.case) AS 'No. of Private Cases Generated',
FROM some_table  ) xx

JOIN (
SELECT c.name AS Company,
CONCAT(UPPER(u.forename),' ', u.surname) AS Username,
count(c.case) AS 'No. of Web Cases Generated'
FROM some_other_table ) xxx
ON xx.Company = xxx.Company;

it fixes the issue This code is only displaying one row. How can I show the other rows that are in the MySQL table when I execute one of the queries? Thank you for anything you can offer! Help is appreciated! , Could you try:
code :
 while ($row = $queryresults->fetch_assoc()) {
 /* do stuff with the $row */
 }

this will help The text 001234 is not the same thing as the text 1234. But if you cast both to integers, then they become the same number 1234.
The moral of the story here is that if you intend the policy numbers to behave just as that, namely numbers, then store them in a numeric column.
code :
SELECT * from POLICY WHERE PolicyNumber = 1234;
