I suspect one of those group IDs has a trailing space or similar 'invible'

Hello,
I'm come across a situation where a table in our production DB has a
relatively small number of duplicative rows that seemingly defy the
unique constraint present on that table.
We're running MySQL 5.6.19a via Amazon RDS. The table in question is
~250M rows.

I am using this query to pull three random comments from a table:
"SELECT *, DATE_FORMAT(created_on, '%b %D') as date_format FROM comments
ORDER BY RAND() LIMIT 3";
The problem is that sometimes, I get two of the same comment. How can I
refine this query to give me 3 unique/distinct ones?

Select COUNT(*)
Select COUNT(*) as num_entries, url from table WHERE num_entries>1 GROUP
BY url
Untested, but the concept should work for you.

Well, doing on all tables at once woule probably bring the server to its knees
due to the cartesian product producing a VERY large temporary table. You can
do it on two tables at once like this (if my memory serves):

WHERE t1.column1 = t2.column1 AND
Thanks for the response, Joshua.
I am so very new to MySQL, that I am afraid I require more guidance.
Is there a way to join ALL tables in a database rather than just one table
to itself, or one particular table to another?

Yes, there is a way. It's called joins. :) I don't remember the exact syntax
off the top of my head, but the approach is thus:
Do a self join on the table and select records that match in their first three
columns, but do not have the same primary key (you *do* have primary keys on
your table
Is there a way to use a SELECT statement (or any other, for that matter)
that will look at every table in a database and return every row whose first
3 columns are duplicated in at least one other row in any of the tables?
Essentially, a command to find duplicate entries in the database . . .

I must admit I'm pretty stumped here. I'm using MySQL 4.0.12.
I have several tables with info, and one which servers as a link between
them (has id's that refer the id's in all the others).
The info tables hold people(table 1), which get assigned to groups(2) by
directives(3) and each time they a
