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.

INDEXES - A Science AND an Art
I've been continuing to look for answers to my own questions. I've found
a few ...
Q1. What good does it do to store the primary key or a unique key if
you're normally SELECTing columns that don't use that primary or unique
key?

I have a few questions about indexes. I understand (1) what an index
is, and (2) why indexes are useful, but I don't have even a rough idea
about HOW they work. The internet resources I've been able to find don't
answer the questions I'm asking. I also tried
cat /var/lib/mysql/srms07/staff.
"Databases are used to store data"
This line spoke the loudest to me. Over the years I had become very
proficient with FileMaker Pro's built in scripting language. I had even
gotten FileMaker to construct the web pages that would be used to
connect to FileMaker (including writing the page's Javasc
Instead of individual replacements, as in ...
SELECT REPLACE('De Long', ' ', '');
would this global approach work?
SELECT REPLACE(imgName,' ','') FROM staff WHERE imgName REGEXP ' ';

Is there a mysql command line equivalent to | less or | more to make it
easier to scan rows one screen at a time?

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.

I've discovered that I can type ...
use mysql;
show tables;
describe user;
update user set user='newName' where user='oldName'
However, this seems to have no effect on the user name in the privileges
table when I searched them.
The MySQL site says the alternative way to do this has the same pro

I'm having problems understanding NULL. I grasp what a NULL value is,
but I can't get NULL to perform correctly. For instance, if I do a
Select statement, I see that I have columns with a NULL value.
select first, last, suffix from persons LIMIT 5;
