ADDATE Question
Hi,
I just tried this query SELECT ADDDATE('2008-01-02', 31); and MySQL returns
323030382d30322d3032, while it should be 2008-02-02 Is there something
wrong?

Re: Adding a column to a huge mysql table
duplicate the table structure, add the column to the new table, import the records into the table. this should be faster based on my experience and also will not disturb your transactions :) On Feb 17, 2012, at 8:21 AM, Angela liu wrote: Hi, Folk: I will need to add a column to a huge mysql table, this table is about 77GB, and has thousands of millions rows. any idea I can make this alter table faster?

WTA Increasing InnoDB Speed
Dear List, I have MySQL 5.14 installed on Dell R710 32GB RAM 600GB SAS HDD with Ubuntu 10.04 64 Bit. I deploy InnoDB as my default engine. The server is a high load server. On a fresh install and empty table it can insert around 5 millions new records per day average. But when the table getting fat the performance starting to drop around 5% per day. It forces me to re create an empty table each month. So how to keep my server has a stable performance?

InnoDB Crash
Hi List, Last night accidentally one of my InnoDB table crash. And cause client can not connect to MySQL, it always said cannot connect to socket, even the daemon is launched. I tried to set innodb_force_recovery from 0 to 6 and only number 3 bring back the connection. After that I dump the data and drop the table. I recreate it as MyISAM and inject the dumped data. After that I stop MySQL and remove innodb_force_recovery and restart. And clients start complaining can not connect. Then I enable innodb_force_recovery again. I tried to create a new InnoDB table test and MySQL complaint cannot create the table due to the engine type is not supported. The question is how to solve this problem? How to bring back InnoDB to my server without reinstall the OS or MySQL itself? I have also tried to drop the database and remove the data folder from mysql data dir and recreate the database but still no luck.

Update Table
Hi, I work on MySQL 5 with PHP 5 and use Apache 2 as the webserver. I have a simple query that searches matched row id and update the field via HTTP GET query. On a low load it succeed update the row. But on high traffic sometimes it failed to update some rows. No errors return by the script. What usually cause this and how to solve this problem?

Re: Persistent Connection VS One Time Connection Was Update Table
I have checked Apache's log. There is no refused connection. And also with MySQL I have set it to 999 connections and view the processes. Maximum connection ever reached was only around 200. What I'm thinking now is. Is it because of I use one time connection method? I mean every time the script's called I create new connection and disconnect it after execute the query.
