The solution was CREATE TABLE copyname SELECT * FROM originalname
I was having problem with a PHP command that's not pulling what I want
from the table Ruling out random order for the rows was narrowing the
focus on the PHP problem.

I went to the MySQL documentation pages and read up on using COLLATE. I
knew SELECT was case-insensitive, but I was sort of surprised that using
a character class didn't override that. Anyway, I next tried the
status command to see if it gave me any characterset information.
Client characterset:
* = mods last to grab anything after that...
actually you should just be able to get by with ^[a-z]

John,
Are you sure they are actually NULL and not NULL (i.e. the string NULL)?
Try this:
SELECT first, last, ISNULL(suffix), LENGTH(suffix) FROM persons LIMIT 5;

For possible educational research purposes, I was playing around with a
query that would randomly select people from a database. The database I
experiment with has a group of fictitious persons with id numbers
(primary key) ranging sequentially from 2 to 378. When I ran these
queries below, I was
using char(10) {I think that is new
line} instead of \n. That should work in both scenerios.
