Cancel A Running Query
Does anyone know if there is a way to cancel a query once it has started executing? I've thought of killing the process through "show processlist". Is there a better way (since I'm calling SQL from a Java application)?

Process Running Long
2874 mysql 24 0 143m 132m 3756 S 0.0 6.5 1296:37 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid- 6 root RT 0 0 0 0 S 1.2 0.0 47:31.78 [migration/2] 3188 mysql 16 0 143m 132m 3756 S 0.0 6.5 9:55.19 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid- Is there any way I can prevent this? This server just has forums on it and thats it. It seems its a runaway process or an orphaned connection. Is there any way to have all processes killed after a certian amount of time like php has in its config file.

When Is A Query Too Long?
I'm just curious to other opinions on the whether you should start to break the sql query in question up, into 2 queries maybe? I have the problem at the moment where I am pulling data from 5 different tables, subqueries and all! I am just not entirely happy with the size of the query and wanted to hear other opinions, Do you try to simplify the query by breaking it up? All tables are normailised (to the best of my ability) and index accrodingly so all that is ok, I am just curious to hear anybody else's thoughts on this.

Table Query Taking WAY TO LONG
I have a query that is inner joined with another table based on country codes Select distinct Name.* from Name inner join Location on Location.key = Name.key and Location.cc in ('<list of countries here>'); The problem is when I have more than 2 country codes, the query takes forever... When I show processlist, it says converting HEAP to MyISAM ( this takes over an hour )... I've tried bumping up max_heap_table_size to 128M and tmp_table_size to 128M, but that only seems to delay the converting HEAP to MyISAM message.... Name contains about 3 million records and Location contains about 1.5 million records. Code:

Error Pasting Long Query Into Terminal
mysql database < /location/of/statement.txt Is there a limit to the number of lines a statement can have in a terminal window? OK, so I just tried the same query on another server and it works in that terminal window? Is there a clip board or cache that needs to be cleared from mysql every once in a while? Why would it work on one and not on another.

Connection Error While Running A Query
I recently started to experiment a connection timeout when querying a table returning 350 rows. The query runs for less than 1.5 seconds. The results are no more than 500K. Usually, the first time the query runs, no errors are returned. However, if I run it a couple times in a row, the second time around, the MySQL server goes offline for less than a minute giving the "no connection" error.

Switch Query Logging While The Server Is Running
It would be nice if general query logging could be switched on and off while the MySQL server is running, and not only at startup time. While debugging an application that uses foreign database access libraries, this would be very helpful. One could switch on logging, perform an activity, switch off logging, and look what has happened. Otherwise, the server has to be restarted to change logging, which is a bit annoying...

Running A Query That Returns True Or False
Is there a specific type of query that can be ran to simply check if a field/value exists, and return true/false rather than returning the entire row? For instance, I want to check to see if "pie" exists as a value under the field "apple" in the "table" table. SELECT * FROM `table` WHERE `apple`='pie' Rather than returning an entire row, or even the value of apple for example (which would be the string "pie"), is there a way to have mysql simply return a boolean "true" instead? Thanks.

Running Multiple Update Querries In Query Browser
I am trying to run multiple update statements together from the MySQL Query Browser. For example: update table1 set field1 = "123", field2 = '456' where rowid = 'abc' update table1 set field1 = "321", field2 = '654' where rowid = 'efg' I can run them one at a time, but I cannot run multiple updates at the same time. I have 1100 of them to run, so I don't want run them individually. In M$ SQL I can just put a ; or GO at the end of each line to seperate it from the next. How can I do this in MySQL?

MySQL Taking Too Long
I'm trying to run a php script written by someone else, not me, and it's getting stuck in a particular step. Actually it isn't getting stuck per se, but the browser is, because it's taking forever to return the results back to the browser. Here's the line that's responsible for this: $users = $db->query_return_array("SELECT * FROM user"); It's getting stuck because in my database I have over 60,000 records. Now, I'm just wanting to get over this step (it's an upgrade script), not looking for fancy proper methods of php coding. What alternative ways are there for me to prevent the browser from timing out? I'm guessing some way of looping through the records, and updating the client with simple update characters to prevent it from timing out.

Mysqldump Long Format (mysql 5.0)
Does anyone know how to get mysqldump to dump in the old style dump format? Right now I get dumps which look like: INSERT INTO cart VALUES ((a,b,c),(d,e,f),(g,h,i),...,(x,y,z)); What I want is the old INSERT INTO cart VALUES (a,b,c); INSERT INTO cart VALUES (d,e,f); INSERT INTO cart VALUES (g,h,i); ... INSERT INTO cart VALUES (x,y,z); The new style is somewhat problematic when trying to diff database dumps. I don't want to have to edit the dump file to do this. I don't see an option for it offhand.

MySQL Keeps Going Long After Code Stops
When some queries are executed on a server I have setup MySQL will continue to use up CPU cycles 5-10 minutes after the PHP code that executed the query has long since stopped. The browser page will be loaded and no further PHP code will be active on the entire server that could call MySQL into usage, yet MySQL will continue to use upwards of 80-90% of the available CPU processing power for that 5-10 minutes afterward. In fact, if the PHP page only takes a couple of seconds to load with next to no CPU usage then after it has finished loading MySQL will start utilizing the CPU for all it is worth as if it is trying to complete some task that only it knows about. This is on an isolated server so I know I am the only one using it. This seems to happen most often when a LEFT JOIN is executed, though the query itself is very quick and returns the data in less than a second. I am running MySQL 5.0.15 with Apache 2.0.54 and PHP 5.0.4 on Windows XP SP2. I know this is terribly obscure sounding, but if anyone has any ideas where I could start to look for the source of the problem I would appreciate it. I know it is not in the code because if I run the code on a Linux server this doesn't happen, not to mention the fact that, as I said, the PHP code itself finishes without a hitch.

Long Text Into A MySQL Field Error

Whne I shorten the text it writes to the DB with no problem. I am getting a long strng, perhaps 200 characters or more into a variable that will then be written to an mySQL DB but I am getting an error in the DB. How can I set the field to accept more than 400 or 700 text characters?

How To Prevent MySQL Queries From Taking Too Long
I have a very busy database with some tables having hundreds of thousands of records. I am running MySQL 5.0.16 on Windows. Some of the queries running on my database are not fined-tuned enough, and need improvement. However, the system is live in production and I am looking for a way to prevent MYSQL from committing Harakiri, i.e. from running very slow queries forever, taking the cpu to 50% and beyond for hours. My scripting language is PHP. I found that after a while the end user receives a timeout on the browser, but MySQL continues trying to run the query, sometimes for hours. My question is, is there a way to specify a timeout for MySQL so that it will abort any queries that it is running that have not returned a result by then. The end user is no longer around anyway, so I am looking for a way to protect the database resources (and in parallel I will start investigating how to optimize the slow queries).

Running MySQL From A CD-ROM?
I have used PHP and MySQL for a few years now. Just today I can across an application that had a MySQL database running locally off a CD ROM. I did not know this was posible. When the application runs it starts up the MySQL database without the user even knowing they are running it. It is pretty amazing. So I want to do the same thing.

Slow Running MySQL?
I'm hoping someone may have an idea what could be causing the slow loading pages of my web-site. I'm not positive, but I'm relatively sure that it's related to a problem with MySQL database. I purchased a program called Sam3 for broadcasting our radio signal over the internet. The software requires the use of MySql in order to set up web pages for our web site. The problem is, that while everything works GREAT (requests can be made from the site, songs can be searched, the history of what we've played shows up) the pages load PAINFULLY slow. Other users of this software have had no such problems so I'm at a loss. I know from testing that the PHP script for the web pages is fine, I have plenty of bandwith both upload and download available on my DSL line, and while the computer running MySQL is behind a router I have tried plugging the DSL line DIRECTLY into the host computer and it makes no difference. For all appearances it seems the problem is that it takes MySQL forever to gather and provide the information needed for these pages. Does anyone have any idea what I should be looking at to solve this problem? I do not know the MySQL program at all, so I get somewhat lost when people start throwing out technical terms, but this has been really frustrating because no one else seems to have the problem and everyone so far has just told me to check the things I've already checked.

How To Use A Copy Of A MYSQL 4.1 Database In MYSQL 5 Running On Ubuntu Linux
We had a "permanent world" game server running on an older PC, under Ubuntu 5.10, using a MYSQL 4.1 database to store persistent data for the players, then the hard disk quit. We did back up our data on a regular basis, but didn't use MYSQL to do the backups, we simply copied the MYSQL/data/ folder to disk. So now we have a new hard disk, with Ubuntu 7.10 and MYSQL 5 installed. We have everything working, in that we have created the appropriate database and, using a simple test module of our game which will create some of the tables if they don't exist in the database, we can store and retrieve data from the database tables. The problem we have is how in the world do we get the data from the backup copy of the MYSQL 4.1 created database into the new MYSQL 5 database correctly? With 4.1 we could copy the contents of the database folder right into the database folder in the /var/lib/MYSQL/ folder, but this procedure didn't work with MYSQL 5. The files seemed to copy, as in the copy operation gave no errors, but we get an error that says the database is unavailable and to make sure the MYSQL server is running - it is, so we're stumped, and our game server is offline.

MySQL Administrator GUI Running Slowly... WHY?
We have created an instance or schema that contains over 14000 tables. It is a lot of tables. When we attempt to browse the tables in the GUI it literally takes 5 minutes or more for it to come back. Granted when using the Microsoft SQL Server Management Studio it is slow but doesn't take that long. After about a minute or so it gives the list and is kind of slow to scroll. Can this be fixed by optimizing the database? Is this just too many tables for mySQL to handle?
