here is an output from

Hi Ben,
When using column/index names with odd characters (such as spaces), you
need to use backticks (SHIFT + the ~ key) around the name: `index id`
This ALTER TABLE query should make all the changes you want:
ALTER TABLE v2easy0_users
DROP INDEX `login connexion`,
DROP INDEX `index id`,

Just use
SET FOREIGN_KEY_CHECKS=0
To turn off all foreign key contraints before you import the data.
Then use
SET FOREIGN_KEY_CHECKS=1
to turn them back on.
Go to http://www.innodb.com/ibman.html and search for foreign_key_checks for the docs.
Hope this helps.

Hi !
I'm working on a regex to validate emails stored in a table.
I'll try other regex from php tips or javascripts tips, but the exact
syntaxe of regex in mysql are differents and nothing work fine... And
I'm not very good with regex :\
I find this :
SELECT email FROM mailing WHERE email
Hi,
Not sure about php syntax, but check out the perl module (in CPAN)
Email::Valid.
Here is the code fragment for the regex:
# Regular expression built using Jeffrey Friedl's example in
# _Mastering Regular Expressions_ (http://www.ora.com/catalog/regexp/).
$RFC822PAT = 'EOF';
Bonjour Matthew !
MS Not sure about php syntax, but check out the perl module (in CPAN)

I'm not searching the PHP syntax, but the SQL syntax... :)

You cannot mark the table as unanalyzed - so you need to rebuild it

Hi
I know that there are two problems when using NFS and MySQL.
One is speed.
My question is that with a good filer like a Netapps with Gig Ethernet would

Two locking.
Why is this a problem? Do locks get missed when righting from the system to
the filer?
