Re: Autoindexing
Under mysql 5.0.18 you can do something like: // get the current value of the auto_increment counter mysql select @@auto_increment_offset; +-+ | @@auto_increment_offset | +-+ |1105 | +-+ 1 row in set (0.00 sec) // set it to your required value mysql set @@auto_increment_offset = 201; Query OK, 0 rows affected (0.01 sec) // make sure it is set to what you want it to be mysql select @@auto_increment_offset; +-+ | @@auto_increment_offset | +-+ | 201 | +-+ 1 row in set (0.02 sec) mysql HTH Keith Roberts In theory, theory and practice are the same; in practice they are not.

RE: New to the group
Well, php was designed basically from the ground-up as a replacement for CGI programming. AFAIK you can do similar things in PERL, but there is alot more to learn. php has an easy learning curve, and seems to be alot more suitable for server sided web programming than PERL. If you are an experienced PERL programmer then you may want to use the Apache PERL module, and do server sided programming with that. If you are new to server side programming then I would recommend starting with php, due to the easy learning curve. See http://www.php.net/manual/en/introduction.php for an intro to what php is, and what it can do. HTH Keith Roberts In theory, theory and practice are the same; in practice they are not.

Re: Problem With Join Syntax
Hi Chris. I cannot see how it can be done with the current table schema. Maybe you need to redeclare your table so the values in the value column are more distinct? What is value supposed to contain anyway? First name, last name and email address? What about a structure like: id | userid | ipf_1 | ipf_2 | ipf_3 1 2 JohnSmith email_addy Which will allow you to retrieve all the values you want from the table as one row without having to repeat the userid column?

Re: my-huge.cnf quite outdated
This seems to be the way things are with mysql nowdays. Is it not time for the developers to take a serious look into culling all the outdated and multiple ways of accomplishing the same thing from mysql and the documentation? All the excess documentation for different ways of accomplishing the same outcome makes the learning curve for mysql alot harder. It doesn't make things any easier for people that want to take the MySQL certification exams either. Why should we have to remember many different ways to accomplish the same thing, when one or two ways at the most would be quite sufficient? For example, do we really need so many ways to start a server? Do we really need different ways to add or drop indexes and modify tables? With the newer versions of mysql (5.0.21+ or maybe version 6.0.x), can we not dump the old syntax that is in mysql for backward compatibility reasons? I would really like to see a slim and trim version of mysql, the SQL commands, and the supporting cli programs, that is up to date and has a very fast learning curve. Just my little gripe.

Re: Transfer users and permissions between servers
Are you moving to a new unpopulated server, or are there already mysql users on the new server? If it is a new server with no other mysql users onboard, then I guess it is as easy as copying the mysql system database (/var/lib/mysql/mysql on my system) across to the new server, with the other databases you are moving. If both servers are connected by LAN, you could set up FTP to transfer everything you need from the old server to the new one. I find Kbear is a very easy to use GUI front end to FTP.

There is no reason why you cannot use diffeent package managers for your system. The only thing is do not run two managers at the same time, as they require exclusive access to the rpm database. Trying to use more than one package manager, or multiple instances of the same one is not a good idea, may not be possible due to locks on the rpm database, or could end up corrupting the rpm database.

For any major changes to a database such as you describe, if you have the disk space, I would advise copying the database and performing your changes on the copy, just in case you do make an irreversible mistake. At least you will still have the original tables to work with again, and not loose your database. As a matter of interest, how large is the database in MB's or GB's?

Re: Find invalid email formats using MySQL query.
Well, mysql has support for regex matching. The thing is
though, why store invalid email addresses in you database?
I think what you are doing is the right approach.
Check the email address validity first in php BEFORE saving
it to the database. At least you then know you are only
storing valid emails in your database.
If you store invalid emails in your database then how do you
get the user to correct the email address from mysql?

Probably the most efficient place to do this sort of field

As far as I know there is no way to do this in a query command. You
have to read every row's email field and then process against the
php code to check/validate followed by a DB delete for all bad ones.
Far better to fix code that edits the email field before adding it
to db.
Denying bad field content before adding it is the normal way this is
done.

{
$reg = ^([a-zA-Z0-9._-]+)@([a-zA-Z0-9-])+(\.[a-zA-Z0-9-]+)+$;
if (eregi($reg, $str)) {
return true;//-- good email
}else{
return false;//--bad email
}
}//--close function
Thanks in advance for any comments or help.

Re: MySQL, PHP and Yahoo webhosting
Hi. call this function, phpinfo(); in a *.php file. That should return alot of usesfull info. Make sure the mysql extension is being loaded. If so check the value of the following php config var: ; Default socket name for local MySQL connects. If empty, ; uses the built-in ; MySQL defaults. mysql.default_socket = /var/lib/mysql/mysql.sock You may need to change the setting in php.ini to tell php to use the correct socket to talk to mysql on.
