MYSQL :: "Lost Connection To MySQL Server During Query"

"Lost Connection To MySQL Server During Query"
Bog standard SuSE 8.2 Linux install.

I have installed mySQL (off the SuSE 8.2 distro CDs). I can connect locally,
e.g:

bealzebub> mysql -u root -p mysql -h localhost

....logs me in just fine. However, this:

bealzebub> mysql -u root -p mysql -h bealzebub

....causes the connection to fail with: "ERROR 2013: Lost connection to MySQL
server during query". Its the same if I try to log in from another machine.

Encountering 2013 Error ("Lost Connection To MySQL Server...")
I have a nightly job that performs backups on my MySQL servers. There are three production MySQL instances on different machines. My backups have been running successfully for months (until now).

However, on last night's backups for one instance, a couple of database/schemas (appear to have) backed up successfully, but the larger schemas failed, as follows:

=======================================
Backup of schema dhunt was successful in 0 seconds
Backup of schema mysql was successful in 0 seconds
Backup of schema support_appl was successful in 0 seconds
Error: Backup of schema support_dict was not successful (1115 seconds):
mysqldump: Got error: 2013: Lost connection to MySQL server during query when retrieving data from server
Error: Backup of schema test was not successful (0 seconds):
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) when trying to connect
=======================================

I re-ran the backup cron job with the same results. Does anyone have any troubleshooting suggestions?

Control Center "lost Connection..." And ByteFX
I'm currently trying to move from MS SQLServer to MySQL, running on
windows XP.

When trying to connect to mysql on localhost with mysql control center
I get the 2013-error "Lost connection to MySQL server during query".

I can connect from command line. If I do so, and change passwords by
using OLD_PASSWORD('<password>'), control center runs nicely, but then
ByteFX fails to connect with "Access denied for user...".

If I set the passwords with PASSWORD('<password>'), ByteFX runs
nicely, but Control Center fails.

"external" MySQL Server MsAccess Connection
I do have rented server space (webhosting) with 3 MySQL databases and a standard URL (e.g. www.1234567.ch).

Is it possible to connect to this "external" server with MsAccess?
If yes how?

Single Query For No Of Hits "Today", "This Month", "This Year"
Is it possible to construct a single query that fetches the no of pageviews "today", "this month", "this year" and "total since start"?

The table is very simple, one field for Date (YYYY-MM-DD) and one for the no of pageviews this day.

If not, would it be much slower/faster to divide the query into 4 different queries?

Relations In "CASCADE", "SET NULL", "NO ACTION", "RESTRICT", "--" ?
what do they mean to set the relations of a Foreign KEY in "CASCADE", "SET NULL", "NO ACTION", "RESTRICT", "--" ?

Lost Connection To MySQL Server During Query / Server Has Gone Away
All of a sudden the server stopped working. When trying to execute a simple INSERT both from PHP and Query Browser, the server crashes and I get either "Lost connection to MySQL server during query" or "Server has gone away" errors.

The problem started on 5.0.18, and upgrading to 5.0.41 didn't help. I'm using Windows XP SP2.

I've seen quite a few posts on similar problems, but no real solutions though. Is that a bug?

Lost Connection To MySQL Server During Query
After changing RAM and the ethernet card of my DB server, the problem of getting
frequent:

Database error (error code 102)
Could not connect to database server (Lost connection to MySQL server during query)

Still occurs ;/

I've tried to eliminate all factors (like multiple servers, load-balancers,
replication etc) so I have wrote a php script that only does the following:

- opens db connection
- does a simple select
- closes db connection

If I refresh this page over and over, every 6-7 times I get the above error.
Anyone have any further solutions, ?? I've tried the software (re-installing
mysql, upgrading, etc....) and tried the hardware (RAM, ethernet card). Nothing
seems to help.

The DB server is Linux Redhat 7.3 with the 2.4.18-3smp kernel. I am running
MySQL standard 4.0.13.

Lost Connection To MySQL Server During Query (error_no 2013)
I am using PHP to invoke mysql_query to my database.
In most cases everything works fine and the query executes perfectly.

ERROR 2013: Lost Connection To MySQL Server During Query
I have recently installed suse 9.0 linux which has MySQL 4.0.15 as part
of the distribution. After I set up my users I was able to use
mysqldump and pipe it into mysql on my windows machine running 4.0.16 to
dump a database to the linux box. However, now when I try to login to
the linux box from another machine on the network I get a query timed
out error immediately after I enter the command line to start the mysql
client.

The error happens with in a small fraction of a second after I type in
the command. I can login from the linux machine just fine though.

Error 2013: Lost Connection To MySQL Server During Query
I have MySQL 4.1.10 running successfully on an office XP machine, but
when I try to set up similar XP box at home I continually get this
error: "Error 2013: Lost connection to MySQL server during query".
The install went fine, and Windows XP is recognizing it as a running
service. But whenever I try to connect via one of my GUI applications
(e.g., MySQLFront), the error appears.

I have scoured this forum and Google looking for this error, but
haven't found anything helpful so far. This post ...
(http://forums.mysql.com/read.php?11,10684,10684) seemed similar, but
my service does not stop when I hit the error.

I've lost a couple days to this problem, and I've uninstalled and
reinstalled the app several times. I don't know where to go next. I
need to have 4.1 running because we need the Unions and Subqueries.

Error 2013: Lost Connection To MySQL Server During Query
I get this message instantly (< 1 second) when I try to connect to the MySQL server from a remote host. I am using "mysql" at the remote client. Does not matter where the remote client is: on Solaris, on RH 7.2, on Fedora. Same thing every time.

I am using the the mysqld as it comes out of the box on Red Hat Linux 8.0.

I tried a google search on Error 2013, and there are a lot of responses:

Lost Connection To MySQL Server During Query After Script Takes 60 Secs
I get the error "Lost connection to MySQL server during query" at the mysql_select_db when reaching this part of the code after 60 seconds of script execuation has already passed. Works fine if the script execution time when reaching this is under 60. Tested with Sleep() and I'm 100% sure that the 60 second barrier is causing it. I just don't know what the barrier is.////

"Too Many Connection Errors" MySQL Status
I have cases where I connect to the web site and MySQL is not working
:

Message : "Too many connection errors", Unblock with 'mysqladmin
flush-hosts'.

What I did is a script that check out /etc/init.d/mysqld status and if
is not running, then, I restart MySQL.

If you accept my Question :
[color=blue][color=green][color=darkred]
>>> What is the status of MySQL when there is the message "Too many[/color][/color][/color]
connection errors", Is it Stopped or Running ?

.. Could we think of something better than restart MySQL using an auto-
'mysqladmin flush-hosts'.

User-defined Function: ERROR 2013 (HY000): Lost Connection To MySQL Server During Query
With mysql-4.1.1-alpha, using any User Defined Function ( UDF) at the
query execution stage, on Linux 2.6, gave me the following error:

"ERROR 2013 (HY000): Lost connection to MySQL server during query"

However, upgrading to mysql-4.1.2-alpha seemed to solve the problem.

Both versions were configured exactly as follows

../configure --with-openssl --enable-thread-safe-client --with-mysqld-ldflags
=-rdynamic

The only way I could solve this was by upgrading to 4.1.2-alpha-log. Then,
recompiling the functions, drop the old UDF functions, then, recreate.
So far so good.

Anyway, if you run into this problem, or just want more detail on the sample
User Defined Functions that come with MySQL ( /sql/udf_example.cc), I've put
my notes in the following link ( TIP 27 )

MySQL Error 2013: Lost Connection To MySQL Server During Query
I'm running sugarcrm on mysql and the following query is returning "MySQL error 2013: Lost connection to MySQL server during query":

How Can I "see" A Table In A Database On A Remote MySQL Server After Creating It
I used the following SQL to create a new table in a database on
a remote MySQL server by copying one already there. I know the
table exists SOMEWHERE in cyberspace. I can read its data, write
to it, delete from it. But I cannot see it. The only way I know it
exists is by running this SQL from Access 97 pass through query:

SELECT ALL new_tbl.name FROM new_tbl

The database resides on a MySQL server that was created with
a single table (named test) in it for testing purposes. I ran the
following SQL to create another copy of the table in the same
database named: new_tbl

CREATE TABLE new_tbl SELECT * FROM test;

I cannot see the new table in the Access 97 database window
under the Tables Tab. Anybody know how to overcome this?

Its a severe drawback to programming efforts not to KNOW what
tables are in your database.

Lost Connection To MySQL Server During Query Socket Error On Read. WSAGetLastError Return 10054($2746)
We just migrated our MySQL database from a NetWare server running version 5.0.21 to a openSUSE box running version 5.0.45.

Everything ran fine for a couple of days, then clients began losing their connections and creating new ones without the old threads being terminated. This behavior is the same for the Delphi client we use to access our database as well as the MySQL Administrator tool.

I've tried adjusting connection_timeout, but overall the settings for this server are the same as the previous one that ran without issues for a year.

"Host Not Allowed To Connect To This MySQL Server"
I just recently installed Fedora Core 4 and was just messing around with the MySQL server, I tried using mysql-administrator to connect to the server and i get this strange error "#HY000Host '192.168.1.104' is not allowed to connect to this MySQL server", I saw mysqlaccess and tried granting myself access to this server but i still get the same error while trying to connect!? Any thoughts?

I Get "Can't Connect To MySQL Server 'name' 10061" (sometimes)
We have a system that runs php5 and MySql 4.1. The apache and mysql servers are on the same in-house network but on different boxes.

If a number of users invoke a page which has multiple queries that access a DB table of about 1 million rows of about 40 times, then the user gets "Can't connect to MySQL server 'name' 10061. This happen very irregularly.

The server chokes and a few seconds later comes back to life. I searched for this and got a lot of hits where users donâ€™t have a connection at all. This is not the case.

- We have a SonicWall firewall, could the firewall think that itâ€™s an attack on a port, when that many connections are coming?
- I also checked dev.mysql.com and got a lot of info on 10061, but itâ€™s only those users who can't connect at all.

Intermittent "Can't Connect To MySQL Server"
Recently, I started getting small periods of intermittent connection errors about once every hour, lasting for about 1 to 5 minutes each time:
Can't connect to local MySQL server through socket
'/var/lib/mysql/mysql.sock'

I enabled the error log and did some other monitoring and established 2 things:
- the server doesn't crash/restart, it keeps running throughout the errors
- the errors do not match the load on the website, as sometimes when 500 users are online there are no errors, but when 300 are online they may by prolific

I checked many forums and then made 5 changes:
- changed the directory containing the mysql.sock file so only file owners or superusers can delete files from it
- I changed the default socket file setting in both my.cnf and php.ini
- I read about SELinux causing such a problem, so I disabled SELinux completely, rebooted the server and double-checked that it is indeed disabled.
- I changed the maximum amount of open files allowed by the operating system from 1024 to 30000.

Despite all these changes, I still get the errors. I then read that there is a workaround by using TCP/IP instead of the sock file. I tried that, but I still get the error intermittently in the form of:
Can't connect to MySQL server on 127.0.0.1

This is a extremely frustrating problem, it's been bugging us for weeks, anyone who can offer some help - it will be greatly appreciated!

REQ: MySQL 4.0 Equivilent Of "DateDiff("m", Date, Now())=1"
I have a query that works in the rest of the SQL world

"SELECT invoice.*, invoice.Date
FROM invoice
WHERE (DateDiff("m", Date, Now())=1);"

which will give me all of last month's invoices.

However it doesn't work with MySQL 4.0.

While

"SELECT
Invoice.*
FROM
invoice
WHERE
(Month(Invoice.Date) = ((Month(Now()))-1))"

Is a close substituent, it will blowup in January.

Anyone have an equivalent expression for MySQL 4.0?

MySQL "Server Types"
I have created a MySQL table in one of my domains control panel (borderprints.co.uk)

$server = "localhost"; .........

........what should i have to access the table in the borderprints.co.uk domain from the dryburghfalconry.co.uk domain....? if possible...?

What Is Execution Time Of A Query Based On? (was "a Mysql Question")
when selecting data from the database, does the time taken to retrieve it vary from 56k connections to T3 connections? or does it all depends ont he general server speed/amount of connections on the db?

im not sure if ive explained that in the best way for people to understand
but im sure someone will get what i mean

Adjacent Theater Seats (was "mySQL Query Issue")
Having not been working with more than a simple SELECT * from table query, I am having a few issues when it comes to using more complex queries.

I am currently using a query to select seats from a database using the following query:

$query1 = mysql_query("SELECT struct.seatid, struct.row, struct.seatnum FROM seats as seat LEFT JOIN structure as struct USING (seatid) WHERE seat.showtimeid=".(int) $_GET['id']." && seat.available = Ƈ' && seat.timelimit < $minutes2 ORDER BY seat.seatid ASC");
For each record that is selected I want to check if either of the seats either side of it are also selected, if not then it is not to be shown.

I have added a while loop below the above query and run another query following it (not sure if that makes sense, so I will paste it below!)

while($rows = mysql_fetch_assoc($query1)){

$minusseat = $rows[seatid] - 1;
$plusseat = $rows[seatid] + 1;

$queryminusseat = mysql_query("SELECT * from seats LEFT JOIN structure WHERE seat.showtimeid=".(int) $_GET['id']." && seat.available = Ƈ' && seat.seatid == $minusseat && seat.timelimit < $minutes2");

$num_rows = mysql_num_rows($queryminusseat)or die(mysql_error());

echo "$num_rows";

//if($minusnum > 0){
//echo "$minusseat " . $rows[seatid] ." $plusseat ";
//} else {
//echo "$minusseat " . $rows[seatid] ." $plusseat ";
//}

}
The code above is used below the initial query and the following error is being displayed:

Quote:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:Program Filesxampphtdocsprojectprototype1 ickets.php on line 154
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE seat.showtimeid=1 && seat.available = Ƈ' && seat.seatid == 1 && seat.time' at line 1

Next And Prev DisplayOrder Values (was "Help With MySQL Query")
I have a table 'Album' containing columns 'PageID' and 'DisplayOrder' (both INT).
On each page that is displayed I want to have 'previous' and 'next' links to other pages, which are arranged via the DisplayOrder column.

At the moment I'm doing this in 2 separate queries:

SELECT DisplayOrder FROM Album WHERE PageID = $currentPage
$currentNo = [result of last query]
SELECT PageID FROM Album WHERE DisplayOrder IN ($currentNo-1, $currentNo+1)
Highly simplified but you get the idea. Would it be possible to combine this into one query?

Script To Change All Columns (was "mysql Query")
I have a table. I need to make some changes like change column name, change int() to var() etc. So I want to write a query that alter all the columns of the table then the data which were in the database before can be reinserted.

How To Stop "many Connection Errors"
I am making a search form using php and the tables will be filled using a visual basic 6 program

Today I just got this error,

but when I used this command I found I do not have the previlages:
mysqladmin: refresh failed; error: 'Access denied; you need the RELOAD privilege for this operation'

I am using shared hosting, so what can I do in both PHP and visual basic to stop those errors.

Server Not "seeing" MySQL
This seems to be a constant problem and a great frustration for newbies looking for alternatives to MS solutions. I had PHP, Apache, and MySQL installed and working on my Windows 2000 machine but now have a new machine with XP. PHP and Apache are working but its as though MySql wasn't even there.

When I run phpinfo() to troubleshoot, there isn't even any reference to MySQL in all the data I get back. Been following the threads on this forum and it looks like everything else is right; my.ini in the right place; libraries in the right place; - who's got the magic bullet?

Unable To Connect To Server (was "Novice User Problem")
I've been reading Kevin Yank's Build Your Own Database Driven Website and am unable to connect to the MySQL server as he describes in Chapter 4 (p. 74-75).

After modifying his code to produce a mysql_error, I get:

Even though I am using the latest MySQL server (5.0).

Not Sure How To Use Inner Join (was "MySQL Query Help Please...")
Basically i have 2 tables users and listings. In users table there is user's info like username / password etc. and in listings table there are listings of a user..which can be more than 1.

Currently I was just getting results by just searching the listings table by a simple query like: "SELECT * FROM listings WHERE title = 'abc'"; but now what I want do is that I can search for some fields in user table also.

For eg. currently listings are displayed..but now i should be able to see all listings by searching username of post code. So please tell me how do i go about it ? I know that it can be done using INNER JOIN but i am not sure how to use it.

Can You Use "UNIX_TIMESTAMP" Outside The Mysql Query?
Hey guys. I was using this code:

mysql_connect($dbhost, $dbuser, $dbpassword) or die("Couldn't connect to server.");
@mysql_select_db($dbname) or die("Couldn't connect to database.");

$q="SELECT poker_room,game_type,limit_type,UNIX_TIMESTAMP(date_time),date_time,buyin_desc,description,url FROM poker_tourneys ORDER BY date_time ASC";
$sql=mysql_query($q);
$num=mysql_num_rows($sql);

mysql_close();

Then using this code to get the results:

while (list($poker_room,$game_type,$limit_type,$dt,$dt2,$buyin_desc,$description,$url)=mysql_fetch_array($ sql)) {
// Blah
}

But I need to only display certain results so depending on the page they are on.. so I was wanting to get each results values with the "mysql_result()" funtion; but I can't figure out how to get the UNIX_TIMESTAMP to work this way.....

Lost Connection To MySQL Server
I am using PHP to invoke mysql_query to my database.
In most cases everything works fine and the query executes perfectly.
Sometimes, I will get a burst of errors and the query will fail with the following error:

Does anyone know what could cause this?
Could this be a mysql configuration problem, or maybe some network problem?
