I've flipped the approved switch to "N", so it should no longer show up.

A quick test brings up a lot of "We die horribly and painfully, you go to hell and I spend eternity in the arms of baby Jesus. Gunn, 'There's No Place Like Plrtz Glrb'"

I just got that one on 4/7 refreshes.

[edit: And, FWIW, every time Read New has sent me to the Message Center in the past few minutes has given me that Gunn quote. Don't know if that's relevant, or just coincidence.

And it's a Gunnathon here, too. Hmm. Plus two Mayors.

It likes the first quote in the table more than it likes all the rest.

Me, I don't really care. I'll toss a seed in and see if anything changes.

I'm researching this in newsgroups, and you know how you said you didn't want to get all the rows and then throw them all away?

That's apparently what it's doing anyway.

Yeah.  Basically this query is implemented as
  (a) select all 35000 rows of "poetry";
  (b) compute a random() value for each row;
  (c) sort by the random() values;
  (d) take the first row, discard the rest.


The good news: this gives you a pretty-durn-random selection.  The bad
news: you didn't really care about choosing a random ordering of the
other 34999 rows, but it computed one anyway.


This problem's been discussed before, but I've not seen any really
ideal answer.  SQL is not designed to offer unpredictable results ;-)

But the database is doing it, and so it's faster than us having to handle a PHP data structure. That's where I want the work to lie. You'd have to page through the record set a random number of times in PHP. I don't like that at all, not on each and every page.

I hope I'm not being a pain, but I honestly don't get this.

Leaving aside the fact that the DB doesn't seem to do Random properly anyway, what are the efficiency issues that concern you?

If we get PHP to pick a random number between x and the number of quotes, then get it to select the quote that's greater than or equal to that number, that's somehow always less efficient than getting the DB to do it? Even though we know that DB does it in a very inefficient way (according to some dude on USENET anyway)?

There's something about back- and and front-end efficiencies that I obviously don't get.

What do you mean "the quote that's greater than or equal to that number"?

I'm missing something. You want to pick a random number between 1 and what? And then select the quote with that ID, or something near it?

select the quote with that ID, or something near it

Well I only said that because you said the ids weren't consecutive, so I was thinking we'd select quote ID $x, and if there wasn't one, it could find the next one up -- is that feasible? Pseudocode: "select where equal to or greater than $x, limit of one"?

Or just go back and rewrite the numbers so they are consecutive.
