When I submit this query, it is just returning a blank white page.

Code:

---

SELECT * FROM `leads`
WHERE (`id` != "31769629-4a63-83b2-de31-49b3a5e72271"
OR `id` != "162541ac-8842-86c9-6fa8-49af50d437e6"
OR `id` != "df61cc92-4af1-6f22-6aa3-4a4a9fd293e6")

Except it is MUCH bigger... I am trying to pull all IDs from a DB of over 22,000 records EXCEPT about 3000 of them.

Any ideas how I can do that without the DB timing out like that?

SELECT *'s pull a lot of data and is slow, especially with MySQL. I wrote a PHP webapp using MSSQL, and working on one now with MySQL, and MySQL is dog slow.

Anyway, try selecting just one field.

Or, you could selecting one-third of the table and union that with the two-thirds and final third.

I thought of trying that.. but I don't know how I would sift out just a third, then grab another third without grabbing any of the same records, then the final third without grab anymore of the same records.

The only way I know how to do this is using a != and that seams to be what is causing it all to time out.

The temporary solution I had to do was pull the whole table... then use Excel to find the matching ID#s from another tab and marking the original list. Then sorting and deleting based on that marking.

With 20,000 records though, it was a pain in my @ss...

I didn't realize what I posted. I wrote one thing but was thinking another. I guess this would be how to do it, not sure if it'll run but it looks okay.

Wait a second, are you trying to retrieve all records but those three? If that's the case, use AND instead of OR.
