Moving database to another machine
Hlo all, I wanted to move around 50 GB of data on Machine A to Machine B. Both the machines are of same architecture ( LAMP ) Dumping and restoring takes a lot of time. Is there a faster method to accomplish the same? Is there a way to tar the whole thing and untar on Machine B? or any other way? Ratheesh Bhat K J

Enums vs prepared statements
Hi,
I try to read enums from a database through the prepared statement API, as a
number.
The enum is defined e.g., as ENUM('Accept', 'Reject', 'Reject_All')
The bind structure is filled in the following way:
buffer_type = MYSQL_TYPE_LONG
buffer points to an uint32_t
buffer_length = 4
length points to an unsigned long
is_null points to a bool
is_unsigned = true
error points to a my_bool
After calling mysql_stmt_fetch() I receive MYSQL_DATA_TRUNCATED, error is
set to 1, and length is set to 4.
Could somebody explain what am I doing wrong? Inserts seem to work woth the
same setup properly, only selects have this problem.
Thx.
ImRe
P.S.: version = 5.0.22

In has 2 forms:
1. IN (subquery). [The word IN is an alias for = ANY (subquery)].
2. IN (list of values seperated by comma)
Hence the exact syntax to use is:
Select fields from table where fieldname = ANY ( select

I have a string comparison that I would like to do against a short

at the moment I am using the syntax
SELECT id FROM t1 WHERE name IN('s1', 's2', 's3', ...);
However, this limits me to exact matches and I'd like to move to a
caparison expersion that lets me match names that contain any of the
list. The MySQL docs state that 'IN()' is an alias to '= ANY()'
however when I substitute' = ANY' for IN I get a parse error. What
I'd like to do is write something like (although I figure there may
be a better way to do the comparison that I am not thinking of):
SELECT id FROM t1 WHERE name LIKE ANY('%s1%', '%s2%', '%s3%', ...);
Does anyone know a way to do this?

2 versions of mysql on Unix: problem with the socket
I am running mysql 4.1.7 on solaris 9. I want to install 2 versions (versions
4.1.7 and 5) on the server. I am reconfiguring my scripts in that perspective.
I have a script that start the mysql v4 so that I finally have:
7002 pts/4S 0:00 /bin/sh /seqweb/mysql4/bin/mysqld_safe
--defaults-file=/seqweb/mysqldata/my.cnf --port=3306 --socket=/tmp/mysql4.sock
--pid-file=/seqweb/mysqldata/mysql4.pid --user=mysql --datadir=/seqweb/mysqldata
7023 pts/4S 0:13 /seqweb/mysql-4.1.7/libexec/mysqld
--defaults-file=/seqweb/mysqldata/my.cnf --basedir=/seqweb/mysql-4.1.7
--datadir=/seqweb/mysqldata --pid-file=/seqweb/mysqldata/mysql4.pid --port=3306
--socket=/tmp/mysql4
The problem is that I always have to give the --socket to all the clients, the
port number is not enough. Ex:
mercure{mysql}139: /seqweb/mysql4/bin/mysql --port 3306
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)
mercure{mysql}140: /seqweb/mysql4/bin/mysql --port 3306 --socket
/tmp/mysql4.sock
Welcome to the MySQL monitor.
Of course I can do it but the problem is when I use client like a perl script
with DBI:
while (DBLIST) {
my $db_name=$_;
my $port=3306;
my $hostname='localhost';
my $socket='/tmp/mysql4.sock';
chomp($db_name);
my $dsn = DBI:mysql:database=$db_name;host=$hostname;port=$port;
my $dbh = DBI-connect ($dsn,$DBUSER, $DBPASS,
{ RaiseError = 1, PrintError = 0 })
DBI connect('database=mysql;host=localhost;port=3306','mysql',...) failed:
Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) at
/seqweb/mysql4/myscripts/4/check_innodb.pl line 58
Where is the problem? Is it in the way I start mysql?
I really would appreciate help! Scripts are below.
Thank you in advance

resources for tuning
Hi, We just upgraded our server's RAM from 1 GB to 5 GB - I'd like to now make some adjustments in my.cnf to better tune my server to this new memory amount. I was looking in the MySQL 4.1.21 source dir's support-files at the example my.cnf files provided with the distribution, but these seem horribly out-dated. (The my-large.cnf assumes you have a whopping 512 mb of memory). I was thinking of modelling my.cnf after the provided my-innodb-heavy.cnf file, but I am worried these files might be out-dated so I figured I'd ping the mailing list for other resources for tuning?

RE: 2 versions of mysql on Unix: problem with the socket
Thank you for your answer.
Here is what I did
cd
/seqweb/mysqlhome
mercure{mysql}140: more .my.cnf
# The following options will be passed to all MySQL clients
[client]
user= mysql
password=
port= 3306
socket = /tmp/mysql4.sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
[mysqldump]
[mysql]
[isamchk]
[myisamchk]
[mysqlhotcopy]
I still have the problem.
DBI connect('database=mysql;host=localhost;port=3306','mysql',...) failed:
Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) at
/seqweb/mysql4/myscripts/4/check_innodb.pl line 62
Also this is a less attractive solution since the same user will work on
version4 and version 5.
Thank you

anyone using subversion to sync mysql dbs ?
Is anyone using subversion to sync live and development databases? If so, how? Is this desired or a best practice? Everything except my databases are under version control. In theory, I would like my databases to sync with the same subversion 'svn update' command. That way, all web content updates with one command. many thanks g -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

MySQL tuning advice
Hello, I am looking for some advice regarding the tuning of a dedicated MySQL database server. The machine in questions is a Dell 2850 with dual Xeon procs and 4GB of memory running FreeBSD 6.1. Its sole purpose in life is to run the MySQL 5.0.x database engine serving out databases to multiple Apache servers. I started with the my-large.cnf file distributed with the MySQL port on FreeBSD 6.1. I made the following changes: set max_allowed_packet = 2M set-variable=max_connections=500 Now the questions: 1. What would be the recommended max_user_connections for the Dell 2850? 2. What is the practical maximum value that max_user_connections could be set to? I have been looking around for documentation regarding a max value for max_user connections and found the following: http://www-css.fnal.gov/dsg/external/freeware/mysqlTuning.html What documentation do others use for tuning MySQL? My goal is to convert our PHP and Perl applications we run on the Apache web servers to use persistent database connections to the dedicated MySQL server. -- Greg Pelle System Administrator Domain-it!

Re: MySQL tuning advice
Really you need to look at what your server is doing, the traffic patterns, then you can tune. There is a lot you can determine by just looking at the output of SHOW STATUS and SHOW VARIABLES. Threads_created number high and growing? Increase the thread_cache_size variable. Opened_tables number keeps growing? Increase the table_cache variable Those are very simple examples and there is a lot more you can tell, including how your indexes are doing. Read up on the status and variables, there is information on ratios and lots of other good stuff to help you change basic things. Careful with persistent connections and PHP, you can easily trip over your own connections. - Original Message - From: Gregory T Pelle [EMAIL PROTECTED] To: mysql@lists.mysql.com Sent: Tuesday, September 12, 2006 12:50 PM Subject: MySQL tuning advice Hello, I am looking for some advice regarding the tuning of a dedicated MySQL database server.

First of all - please reply to the list ..
I thought you wanted all fields, that's the way your
SELECT statement is
constructed. If just the first 20 char from fieldA, then ...
SELECT LEFT(fieldA, 20) AS fieldA FROM Tab1
should do what you want. Again, check the syntax for LEFT() in the
MySQL docs.
the syntax is valid:
from http://dev.mysql.com/doc/refman/5.0/en/string-functions.html:
LEFT(str,len) returns the leftmost len characters from the string
str, or NULL if any argument is NULL.
mysql SELECT LEFT('foobarbar', 5);
- 'fooba'
I have 30 fields: instead writing all 30 fields, I would want to
select them all with * and only for one of they, fieldA, to
obtain the
first 20 chars: it's possible?

Dear all, I've encountered a very strange problem. I dumpped one table from a database and then import it into another database. I works successfully, all the data is exactly the same. But when I the below SQL on two tables: select * from foo_table ORDER BY id DESC it shows up different result. All result truely sorted by id by some of them appears different. Can someone help me on this problem? Any suggestion is extremely welcomed.
