Re: what is this? -- errno=2006 errmsg=Server gone
This is software I use: D:\MDmysql --version mysql Ver 14.7 Distrib 4.1.12, for Win32 (ia32) C:\Apache\Apache2\binApache.exe -v Server version: Apache/2.0.54 Server built: Apr 16 2005 14:25:31 C:\Apache\Apache2\binver Microsoft Windows 2000 [Version 5.00.2195] Exactly which parameters can I tweak to fix this error (i.e. errno=2006 errmsg=Server gone)?? At this stage _any_ help/hint/guess would be really appreciated. regards, martin Dilipkumar wrote: Hi, If this is related to mysql please let us know what version you are using (Mysql) and which OS.

'ODBC'@'localhost' instead of 'root'@'invalid_hostname.com' ?!??
Hi, I'm using PHP/MySQL to development a web-based application. I just upgraded both PHP and MySQL and I noticed that some of my MySQL calls are now broken and I don't see any easy way to fix them. My script calls mysql_connect() and does very careful error checking. It's important that I can tell apart invalid hostname errors from say incorrect username/password errors. Previously, I did this by checking mysql_errno(), where 2003 would mean bad hostname and 1045 would indicate bad username/password. In the latest PHP/MySQL bundle I downloaded this functionality changed though. In this new version, whenever I feed it with a invalid hostname it will fallback to localhost (where I actually have a database running) and then it will subsequently report a 1045 instead of a 2003. Oddly enough, the exact error message (mysql_error) I get attached to this 1045 says; mysql_error()== Access denied for user 'ODBC'@'localhost' (using password: NO) Now, what is this about? I sure did not feed it with a username 'ODBC'. I do use Windows 2005 but how could ODBC possibly be related to this? (I assume ODBC means that [Microsoft?] database connection thing, I'm not sure exactly what is it; i've never used it). For the record, the actual username I specified in the call with the invalid hostname was root. --- So, the question is how can I tell these errors apart? Why is mysql_error() reporting back that it tried to connect to localhost as user ODBC when I asked it to connect to an invalid hostname as user root ?!?! sincerly, martin -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Circumventing the max_allowed_packet limit?
Hi MySQL ppl,
I recently ran into some problems with uploading large files through a
HTML form and then putting these files into a MySQL BLOB field. I read
about the server parameter max_allowed_packet which turned out to be the
problem.
My script is going to be redistributed to it needs to run smoothly on
many different servers. Therefore I'm now looking into ways of avoiding
this problem, and I also want to avoid forcing the script users to
reconfigure his MySQL server.
Now, my questions are:
Q1. Can I divide my query into several packets and thus insert the large
BLOB without exceeding the max_allowed_packet limit?
Q2. I doodled around a little bit with the SET command and I was able to
change the session version of the max_allowed_packet server parameter.
The insert query still failed though, even if I did successfully execute
the SET max_allowed_packet=16MB query and also double checked it with an
extra select afterwards; and it had indeed changed. See the code below.
The question is, is this is viable method? Is the local/session version
of this variable just ignored by the server?
My code (for Q2):
$result = mysql_query(SELECT @@local.max_allowed_packet AS
max_allowed_packet;);
$row = mysql_fetch_assoc($result);
echo max_allowed_packet= . $row['max_allowed_packet'] . \n;
$result = mysql_query(SET @@local.max_allowed_packet=1600;);
if (!$result) {
echo It did not work. . mysql_errno() . : . mysql_error() . \n;
}
$result = mysql_query(SELECT @@local.max_allowed_packet AS
max_allowed_packet;);
$row = mysql_fetch_assoc($result);
echo max_allowed_packet= . $row['max_allowed_packet'] . \n;
mvh

Checking max_allowed_packet from PHP during runtime?
Hi MySQL gurus, I'm using the LAMP stack and I'm currently creating a script that allows file uploading through a HTML form. The script itself is to be redistributed so I do not really know anything about the systems it runs on, except maybe that it's LAMP. I keep getting errors because I upload to large files, ie the files are larger than the MySQL servers max_allowed_packet parameter. I would like to check this value during runtime and take proper action. So; How can I check the value of MySQLs max_allowed_packet parameter from a PHP script during runtime? I tried this before: ?php connectToDatabase(); $result = mysql_query(SHOW VARIABLES); $row = mysql_fetch_assoc($result); echo VALUE= . $row['max_allowed_packet']; ? But this does not work, as SHOW VARIABLES seems to be console only; not a valid query. How can I proceed? regards, martin -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Can I make empty MySQL use less disk space?
Hi, I just noticed that the MySQL (win32) program which empty databases take up about 70Mb on my harddrive. I'm deploying MySQL as a part of a greater application (which is much smaller), is there any way I can reduce this size somewhat? I mean like, the examples, directory isnt really necessary is it? So which files can I exclude? mvh. /m -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Default accounts and custom installtion directory
Hi, First, if I install MySQL on a win32 system which are the default account and from which hosts can those be accesses? Which of these accounts am I encouraged to remove or change the password of? I know that the root/ accounts needs to be changed but what else is there? Secondly, if I move like to move the entire C:\mysql directory to some other disk, can I do so without re-installing? If I need to change to registry setting and/or .ini configuration file, what key/files are these?
