Mysql 5.0 - Using My.cnf - Unix / Slow-query-log
I installed mysql 5.0 and need to set up slow-query-log and other logging options.
Here is what I did. But I dont see it working yet.
1. cd /var/db/mysql
2. chown mysql slowquery.log
3. touch /usr/local/etc/my.cnf
4. chown mysql /usr/local/etc/my.cnf
vi my.cnf
[mysqld_safe]
-u mysql
--log-slow-queries=/var/db/mysql/slowquery.log
so now when I type:
mysqladmin shutdown
and than
mysqld_safe &
my sql restarts but the log files are not being used.
also - how do I know if my my.cnf is being used at all?

VER VERY VERY Slow MySQL Query HELP URGENTLY NEEDED
I have the following MySQL query, but it is VERY VERY slow and seems to be crashing the server. There are 300,000+ records in the 'tracker' table.

Slow Query
i have this query on a website/webapp that has expanded beyond all expectation. It now takes nearly 30secs to return results from the database SELECT cl_t.Client_ID, Buyer_1_Title, Buyer_1_Prename, Buyer_1_Surname, Tel_No, Mob_No, Buyer_2_Title, Buyer_2_Prename, Buyer_2_Surname, Email_Add, Price_Max, MAX(activity_t.Date) AS lastcomm FROM cl_t INNER JOIN cl_want_t ON cl_t.Client_ID = cl_want_t.Client_ID AND Agency_Code ='$agencyloggedincode' AND Deleted = 'N' LEFT JOIN activity_t ON Buy_Sell = 'B' AND Ref_No = cl_t.Client_ID WHERE cl_t.Sales_Agent_ID = $agentid GROUP BY cl_t.Client_ID ORDER BY $order The problem is the call to MAX(activity_t.Date) AS lastcomm activity_t holds all known contact with all known clients and as such is a very large table, the call to search through all of these records and return only the date of the last entry for this client is taking the time. If I remove this from the query I get results in 3 seconds. I have indexing on activity_t.Date & activity_t.Ref_No Question, is there a way of doing this quicker within the table I already have, or should I create another table that just holds the last update date for each client, and get the date from this much smaller table.

Why Is This Query Too Slow?
I find this query to be exceptionally slow(around 2.5 seconds), could some tell me why this is so? MySQL SELECT st.profile_views,count( DISTINCT p.ID ) news_submitted, count( DISTINCT pv.ID ) news_voted, count( DISTINCT pcom.ID ) news_commented, u.joined, u.weight FROM users u LEFT JOIN posts p ON p.submitted_user_id = u.user_id LEFT JOIN post_votes pv ON pv.user_id = u.user_id LEFT JOIN post_comments pcom ON pcom.user_id = u.user_id LEFT JOIN stats st ON st.user_id=u.user_id WHERE u.user_id='john' GROUP BY u.user_id I traced the cause to this line count( DISTINCT p.ID ) news_submitted (from LEFT JOIN posts p ON p.submitted_user_id=u.user_id) But when i execute something like this MySQL SELECT count( DISTINCT p.ID ) news_submitted FROM posts WHERE submitted_user_id='john' it is quite fast (around 0.03 seconds) So why does it slow down when i'm joining the above query with 3 other tables ? Should i use INTEGER for user_id instead of string like 'john'?

Slow Query Log Not Staying On
I'm running MySQL 4.0.16 on Windows 2003. I just added the mysqld-nt command line option to enable the slow query log, started MySQL, and the option showed up as turned on. Then later I restarted the server, and the slow query log option went back to being turned off. Is this a Windows problem in not remembering the service parameter? Has anyone else seen this?

Query Execution Too Slow!
I have migrated from MySQL 4.1.22 to MySQL 5.0.45. Many of the queries that were working on my old server is working too slow in my new server(MySQL version 5.0.45). I am not aware why is this happening. Actually there is no error message or query failing. The query is executing, but the time taking to execute the query is too long. This problem is not occurring for all queirs, but only for some complex queires, that is queries with Left Join or Right Join, Group By etc. I have also checked the MySQL details through SSH(that is by mysql> SHOW VARIABLES;) Now one thing I found is there is lot of difference in key_buffer_size, table_cache, join_buffer_size, read_buffer_size, read_rnd_buffer_size , table_cache etc between my new server MySQL and old server MySQL. Will this be the reason for query execution taking too much time. Can any one guide me why this is happening. The striking thing is that these quires was working very much fine and faster in my old server.

Federated Tables Slow? (like 4.5 Hrs For A Query)
I've got a problem with federated tables. I'm using MySQL 5.1 (with InnoDB as the default table type) on a Win2K server, on which I've got four federated tables pointing at four MyISAM tables on a MySQL 4.1.11 server. Of the four tables, three of them run just fine, and I can retrieve data quickly with no problems. The fourth is a sheer pig. While they have different columns, all four tables are roughly as complex as each other, all having the same features and developed by the same team. The most obvious difference, and what I suspect might be the problem, is that the first three tables have between 150 and 1,000 records, the fourth table has closer to 15,000. Still, there isn't that much lag when I'm pulling from the smaller tables, and the lag is really serious when I'm pulling from the larger one; I ran three queries last night to test, and I could pull data from the smaller tables in about 5 minutes, but the larger table took 4.5 hours- possibly because it was joined with two other tables, but the joins on the smaller tables didn't cause this kind of problem. The second obvious difference is the fact that I'm pulling from a MyISAM table into a federated table... from which I would like to store into an InnoDB table, but it ends up timing out quite a bit. Connecting to the database I've federated to isn't a problem. It responds to a PHP frontend lightning-fast. It's just my federated tables that suck so bad. I wouldn't even use federated tables, but I need to pull from the MyISAM database for storing historical records of inventory. What am I doing wrong, and what can I do to speed things up?

Turning On Slow Query Logging?
Background: I paid a young admin set me up on a database server. He installed the basic I needed for the server...at my request...No Cpanel...mysql and apache and some tight security w/o even a domain name to SSH into. Unfortunately, he's a busy kid, and teens sometimes don't realize that people depend on them...and well, I can't really seem to get him to do much so I gave up and figured it's a good way to force me to learn all this myself... Well anyway, now I want to turn on Slow Query logging. But before I do that, I need to know how MySQL is running. Is SQLogging turned on already? Where is it logging to? So first thing I want to look up is, when the server is rebooted, what's the command to restart mysql? No clue. How do I change the setting? And of course, the server is production, so when I make the change, it needs to be quick, it needs to be smooth, and I need to be able to roll back to the previous config if necessary. I'm running Redhat Enterprise.

Slow Query W/ Join & Ordering
I am trying to figure out why I have a hugely slow query (~2 seconds in my testing environment). Details are below: It involves two tables, products and vendors. Products is a huge table, so I will only include the (ostensibly!) relevant fields in its description: CREATE TABLE `products` ( `id` int(11) NOT NULL auto_increment, `vendor_id` smallint(6) NOT NULL default Ɔ', `product_code` varchar(255) NOT NULL default '', `internal_name` varchar(255) NOT NULL default '', `lastmodified` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP, PRIMARY KEY (`id`), UNIQUE KEY `product_code` (`product_code`), KEY `vendor_id` (`vendor_id`) ) ENGINE=MyISAM; Vendors are much more straightforward: CREATE TABLE `vendors` ( `id` smallint(6) NOT NULL auto_increment, `name` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM; The following query executes in no MORE than 0.01 seconds: SELECT DISTINCT p.id , p.product_code , unix_timestamp(p.lastmodified) as lastmodified , p.internal_name FROM products as p ORDER BY p.product_code ASC LIMIT 0, 30; And has the following attributes: +----+-------------+-------+-------+---------------+--------------+---------+------+-------+-----------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------+-------+---------------+--------------+---------+------+-------+-----------------+ | 1 | SIMPLE | p | index | NULL | product_code | 257 | NULL | 25124 | Using temporary | +----+-------------+-------+-------+---------------+--------------+---------+------+-------+-----------------+ When I join with the vendors table, so that I can fetch the vendor's name for each product, I use the following query, which takes about 1.88 seconds: SELECT DISTINCT p.id , p.product_code , unix_timestamp(p.lastmodified) as lastmodified , p.internal_name , v.name as vendor_name FROM products as p LEFT JOIN vendors as v ON v.id=p.vendor_id ORDER BY p.product_code ASC LIMIT 0, 30; It has the following characteristics: +----+-------------+-------+--------+---------------+---------+---------+--------------------------+-------+---------------------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------+--------+---------------+---------+---------+--------------------------+-------+---------------------------------+ | 1 | SIMPLE | p | ALL | NULL | NULL | NULL | NULL | 25124 | Using temporary; Using filesort | | 1 | SIMPLE | v | eq_ref | PRIMARY | PRIMARY | 2 | te_inventory.p.vendor_id | 1 | | +----+-------------+-------+--------+---------------+---------+---------+--------------------------+-------+---------------------------------+ Note the addition of the filesort. I'm unhappy enough about the temporary, which I don't really understand, but the filesort is, I'm fairly sure, killing me. Closer investigation (or maybe just common sense if you aren't a MySQL newbie like me) shows that the ORDER BY clause is responsible, for when I join without the ORDER BY, my query time goes back down to 0.01 seconds or so: mysql> explain SELECT DISTINCT p.id -> , p.product_code -> , unix_timestamp(p.lastmodified) as lastmodified -> , p.internal_name -> , v.name as vendor_name -> FROM products as p -> LEFT JOIN vendors as v ON v.id=p.vendor_id -> LIMIT 0,30; +----+-------------+-------+--------+---------------+---------+---------+--------------------------+-------+-----------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------+--------+---------------+---------+---------+--------------------------+-------+-----------------+ | 1 | SIMPLE | p | ALL | NULL | NULL | NULL | NULL | 25124 | Using temporary | | 1 | SIMPLE | v | eq_ref | PRIMARY | PRIMARY | 2 | te_inventory.p.vendor_id | 1 | | +----+-------------+-------+--------+---------------+---------+---------+--------------------------+-------+-----------------+ Any clues on how I can get the execution time to go down when I am sorting? I'm also curious why MySQL is using a temporary table,

Help Rewriting A Slow Phpbb Query
I have a "glance" or "Recent Topics" list on my forums that have become fairly complex. I modified an already feature rich glance mod to allow users to select individual forums to exclude from showing topics in the list. As well when users are members of certain forum groups, they see topics from the group forum in the list, and they are highlighted a different colour. The main SQL query to create the list often is showing up in the MySQL Slow_query log and I'm pretty sure is the main cause for the page loading slow. I am no mysql Guru, so I thought I would seek the advice of some to improve or totaly rewrite this slow query. PHP $sql = "SELECT f.forum_id, f.forum_name, t.topic_title, t.topic_id, t.topic_last_post_id, t.topic_poster, t.topic_views, t.topic_replies, t.topic_type, p2.post_time, p2.poster_id, u.username as last_username, u2.username as author_username FROM " .

" LIMIT " . $glance_recent_offset .

815,000+ Records, DB Table Query Too Slow
I have a database table with about 815,000 records in it, each record containing the source of individual webpages (with all the tags and multiple spacing stripped out leaving just the words). At first my match boolean queries were fine but once I got to around 100,000+ records it became too slow to use for a web-based search tool. I was able to separate the data into 10 tables and then use AJAX to run the match query on all 10 tables at the same time and that has increased performance. My question is, is it possible for me to increase the performance for the 1 table some how instead of resorting to separating the data into multiple tables? Is MySQL the right DB for this kind of setup, would MSSQL or PostgreSQL perform better for larger sets of data? I'm not sure how MySQL 5 clustering works,

Large Table, Slow Query Question
I have a table with ~800,000 records. I need to grab random rows from the table based on certain criteria. The problem is that average lowest subset to grab the random row is around 200k. Here is what I'm trying to do: There are 4 columns: data,n1,n2, and n3. I need to get the value of the data column based on criteria using the n1-n3 columns. The most common query is SELECT data FROM table WHERE n1 = ? The problem is that n1 can be only 1 of 5 possiblities. When the table is finished being populated there will be roughly 1.5 million records and 250k for each value of n1. Of course, I have an index on each n column. Right now with just the 800k records it can take over a second, sometimes multiple seconds to run the following in order to get a random row from that subset: SELECT COUNT(1) AS total FROM table WHERE n1 = 3; index = random number from 1 to total SELECT data FROM table WHERE n1 = 3 LIMIT index,1; How can I speed this up? I need it to take less than half a second if possible. Thank you.

Can't Insert A Unix Timestamp Into Mysql
Just upgraded to 4.1.8 and when I create a field with a date value (field is trdate), it always has default of 0000-00-00. And when I insert values with unix timestamp values (which I prefer, and they come from php's strtotime function),the record does not insert properly. I tried to set, through phpmyadmin, unix/current timestamp and to no avail. If I use a strtotime php function to convert a date into a timestamp, what is the proven way to make sure that value is saved during inserts? I am on the mysql manual, searched this board, but nothing works.

Can someone help me modify my code so that this same idea will also in my code? <tr><td colspan="2"> <?php $datetime=$row["time" + 0]; $year = substr( $datetime, 0,4 ); $mon = substr( $datetime, 5,2 ); $day = substr( $datetime, 7,2 ); $hour = substr( $datetime, 9,2 ); $min = substr( $datetime, 11,2 ); $sec = substr( $datetime, 13,2); $orgdate = date("l F dS, Y h:i A", mktime( $hour, $min, $sec, $mon, $day, $year)); ?> <b>Date:</b> <?php echo $datetime; ?></td></tr>

Import Dump From Unix Mysql To Windows Mysql
I am trying to load a dump from a MySQL database on my ISP's server to my development environment on a Win 2K machine (running MySQL). When I run the mysql command to run the load script, MySQL gives the following complaint: "ERROR 1064 at line 21: You have an error in your SQL syntax. Check the manual t hat corresponds to your MySQL server version for the right syntax to use near 'D EFAULT CHARSET=latin1' at line 7" The dump from the ISP's server is created using mysqldump. The ISP is running MySQL 4.1.20. My development environment is MySQL 4.0.26. I have no problem loading dumps made from my development environment usng phpmyadmin.

Which Is Faster In MySQL? Comparing Unix Times, Or DATETIMES?
I'm leaning towards using unix times inserted into my MySQL for ease of use in manipulating the data with PHP. I think this will be the final decision, which one would be faster? -- Mysql: * INT (4 bytes) * DATETIME (8 bytes) * TIMESTAMP (4 bytes) -- My PHP application does alot of querying from the database to compare specific data within TIMERANGES, so always, I'm querying with "time >" or "time <". My question is would doing the WHERE time query with the native MySQL DATETIME be faster, than doing a WHERE query with the unix timestamp?

Slow MySQL
mySQL has been running very slowly and I am getting errors. First I did 2 things I raised the ServerLimit number (apache) to allow for more connections, I also raised the max conncetions in my.cnf. I do not know if this took effect? That should have worked. But basically in phpmyadmin i get this error frequently. I am getting more traffic so I think it is that. MySQL said: Documentation #2002 - The server is not responding (or the local MySQL server's socket is not correctly configured)

Why Does MySQL So Slow
I just changed to use MySQL few days ago but it was a bad idea. My server now is running very slowly with the database. I'm using Perl5 and DBD::Mysql in my script. The system is Linux9, Apache2. I looked at these mysql pid and saw a lot of activities (about 400) while there are more 100 users online at this moment and lots of running under a the same pid number.

MySQL Slow
I had downloaded a few years back mySQL v3.51 installed but never used it. Now I wanted to convert some B-TREE databases to mySQL and did some testing via ODBC to insert 70,000 records: My results: MS ACCESS: ~60,000 msecs MYSQL v3.51 ~18,000 msecs Impressed with the speed, I went ahead and got the latest MySQL v5.1. Uninstalled the older version, I had nothing there to preserve, so I did a simple new install with MySQL v5.1. I noticed the size of the files and BINEXE increasted by 1,000,000%. Ok, Bulky. Not a problem. I reran the same ODBC test, and now I got: MYSQL v5.1: ~450,000 msecs or 7.5 freaking MINUTES! What the hell happen? Nothing was done. I'm knew to MYSQL. I just installed it with all the defaults. I did choose "developer's machine" for the "optimizer wizard" I can't redistribute MYSQL v3.51 and force it down people's throats! I have to use what they are using already, if already installed. Not even my current system takes 1 minute to add 70,000 records. Why 7.5 minutes? All it is simple inserts/free statements.
