Query Question
I have a couple of very simple tables to handle a client signin site: The client table has the following fields: client_id int(11) primary key auto_increment first_name char(90) last_name char(90) The signin table has the following fields record_id int primary key auto_increment client_id int date datetime Essentially, the client enters his id and it creates a record in the signin table. I need a query that can identify all the clients who signed in for the first time during a specific month. I have fought this one for a couple of days now and just can't seem to get it. -- Aaron Clausen [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Tough Query Problem
I am trying to write a script that can take logs from our mail server, boil down the rejections to determine the sources of distributed SMTP dictionary attacks against our mail server. Basically I have a table send_failures like this that gets fed with the raw data from the logs: host_ip date --- 111.111.111.110 2004-06-03 13:42:22 34.23.28.1 2004-06-03 13:42:25 65.2.88.25 2004-06-03 13:42:25 111.111.111.110 2004-06-03 13:42:27 65.2.88.25 2004-06-03 13:42:29 64.251.68.722004-06-03 13:42:30 And so on and so forth. Now it's trivial to write a query to find the pure counting of the attacks: SELECT host_ip, COUNT(host_ip) AS attempts FROM send_failures GROUP BY host_ip; However, I also want to have latest date of the attack included as well, so that the above exampe would boil down to a query with results like this (I'm running MySQL 3.23.58): host_ip attemptslast_attempt_date --- 111.111.111.110 2 2004-06-03 13:42:27 65.2.88.25 2 2004-06-03 13:42:29 64.251.68.721 2004-06-03 13:42:30 65.2.88.25 1 2004-06-03 13:42:25 34.23.28.1 1 2004-06-03 13:42:25 Obviously the actual table is going to have hundreds of thousands of entries (the log file for a couple of days ago had 1.2 million rejections). -- A.

IP Address Operations in MySQL
I'm running 3.23.49 on a Win2k machine and wonder if anybody has some advice on how to write queries dealing with IP addresses. Specifically, I have a table with an ip address field. I want to be able to do queries based on subnet. Has anybody got anyting like this? -- Aaron Clausen [EMAIL PROTECTED] or [EMAIL PROTECTED] -- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Doesn't mysqldump also create sql files or at least create the commands to rebuild what it is dumping? Using default options, it creates a SQL script that will create the table structures and reload the data. You can use the mysql command to repopulate the database. I'm in constant development of an in-house accounting system, and to test out bug fixes, new features, etc., I'll just dump the running database and pipe it into a test database. I found mysqldump to have a bit of a learning curve, but I could not survive without it now. -- Aaron Clausen - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Every attempt I have made to find a decent way of backing up a database ends up with tons of reading to show hundreds of ways to do database backups. I want to know which way to do complete backups is most commonly used by professional users.

Is there any similarily convenient way to do this with mysql, for example: * a shell script (windows / Linux) that works as expected without days of configuration? * scheduled backups, complete or differential? * GUI-solution ??? (mysql control center does not even mention the word backup) Backup is such an important issue. Why does it seem like it is something that the developers don't care about?

MySQL has been rock solid for our applications, the MySQL development team is great to work with, and our customers like it. That's been my experience as well. We have an in-house billing system which I originally wrote to work with MS-Access. I converted the whole thing over to MySQL via ODBC in June 2000, and it has worked flawlessly ever since. We run it under Win2k, though I'm seriously thinking of moving the database server over to Linux in the next six months. But MySQL has been rock solid.

The fact remains that plenty other examples exist where MySQL could benefit from the .NET Framework. WILL MYSQL BE USING THE MICROSOFT .NET FRAMEWORK IN FUTURE DEVELOPMENT OF THE WIN32 PORT? I think that anyone developing portable software should stay as far away from Microsoft-specific tools as possible. I see no reason to further cloud a difficulty area by popping in the latest MS fad, which, no doubt, in four to five years, will be replaced by some other marketing-driven fad. In other words, the rule of thumb should be Keep it simple, stupid. -- Aaron Clausen - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Best Column Type for Currency Calculations
I've been having some problems with currency calculations in SQL queries. I've been using Double, but often get some very small rounding errors. What is the recommended column type for currency in MySQL?

How much difficulty is there in turning a MySQL replication server into a master?
