Regular expression not working as expected (documented)?
I must have understood something wrong in the regexps docs:
SELECT
login
FROM
orolixMain.Usersu
WHERE
u.login REGEXP
'^wa[bhkl][_[.period.]-acegmnopqrsuvwxyz]{1,5}[14Lt][23890IJOQ].*'
;
[EMAIL PROTECTED](none) \. usr/src/oro/qry/phshr.sql
+---+
| login |
+---+
[…]
| walt[…] |
[…]
+---+
49 rows in set (4.46 sec)
The regexp I used was to return strings began by wa, followed by [bhkl],
and then by one to five characters in the [_[.period.]-acegmnopqrsuvwxyz] list.
But I get, among otherss, a string beginning with 'walt' (several, in fact).
Ideas?

Probably MySQL don't know about this [.period.] thing and just takes the
. in it
as any char, e.g. your t from walt.
I got that from cname.h, mentioned in the MySQL regexp documentation.
Try '^wa[bhkl][-_acegmnopqrsuvwxyz]{1,5}[14Lt][23890IJOQ].*', if there is a
- at the
beginning of a character class it is usually threaten literally as it makes
no sense
as from..to separator in those cases.
Hm, but I do need to take into account the period.
Also, do you mean the - at the beginning will make all following
characters be treated literally?

OK, I had taken the effects of - as being the effects of .
REGEXP BINARY '^wa[bhkl][-_.acegmnopqrsuvwxyz]{1,5}[14Lt][23890IJOQ].*'
It indeeds works much better.
I tried to improve it:
'^wa[bhkl][-_.acegmnopqrsuvwxyz]{1,5}[14Lt][23890IJOQ][-_.acegmnopqrsuvwxyz]*'
This is to account that the last characters can’t have ascendents
(don’t ask me why), but it still doesn’t seem to be quite right:
[…]
| wabatizelli | -- I don’t want two ‘l’s
| wabetosp| -- I want one of [23890IJOQ] after that t
| walvent33 | -- I don’t want two ‘3’s, only one.
[…]
I tried putting {1} after each of [14Lt] and [23890IJOQ] to no avail;
and MySQL didn’t accept *? at the end, to become non-greedy.
Perhaps regexps are just too hard to me…

Re: Pushing mysql to the limits

This is a hard call. You will have to keep data consistent among servers, and MySQL does not support distributed transactions: it does have the XA interface, but it does not do its job properly. As far as I know, the only free SQL DBMS supporting distributed transactions is Ingres. We are planning to use Intel based machines and will prefer ISAM since there is not much updates but mostly selects. You are asking for trouble. Hear the voice of experience. So, what I wanted to learn is how much can we push it to the limits on a single machine with about 2 gig rams? Do you think MYSQL can handle ~ 700-800 gigabyte on a single machine? Probably yes, but it will all depend on what you will do precisely with it. Anyway, you would be much better of with a more solid system, preferrably with proper XA distributed transactions (two-phase commit). And, is it OK to put this much data in a single table, or should we divide it over multiple tables? With a proper DBMS, you can partition the table in physical segments without complicating the logical model. Check Ingres or PostgreSQL, perhaps MySQL’s own MaxDB. -- Leandro Guimarães Faria Corcete DUTRA +55 (11) 9406 7191 (cel) Administrador de (Bases de) Dados +55 (11) 2122 0302 (com) http://br.geocities.com./lgcdutra/+55 (11) 5685 2219 (res) BRASILmailto:[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
