Mysqldump certain tables

Hi,

I have to upload part of my database periodically when i make changes to product data etc. However I only want to upload certain tables. We suffer from bandwidth chock here, so i want to write a couple of separate scripts that upload parts of the database that changed. The database is large and it is split into to sections Feed driven data, which is 27MB and Manual driven data which is 8MB. To reduce the upload time i decided to write a script that uploads the feed stuff (to be run once a month) and another script to upload the manual stuff (could be run daily) to reduce the upload time. I therefore decided i would have a script to copy the sections of the database in to a smaller database on the development server. Then a script on the live server to download the smaller database from the development server. I am however having troubles creating the first script.

Here is what i have.

Code:

mysqladmin -u root --password='mypassword' --socket=/tmp/mysql.sock drop DATABASE_TEMP
mysqladmin -u root --password='mypassword' --socket=/tmp/mysql.sock create DATABASE_TEMP


for table in TABLE TABLE2 TABLE3 TABLE4 TABLE5
do
echo "copying table"
mysqldump -u root --password='mypassword' DATABASE $table | mysql --socket=/tmp/mysql.sock -u root --password='mypassword' DATABASE_TEMP
done

Am i on the right track? Should i be doing this with a single command somehow? Will this work? I am reluctant to test it without some advice because i don't want to much anything up.

pmdamysql

PMDAMYSQL(1)						       Performance Co-Pilot						      PMDAMYSQL(1)

NAME

       pmdamysql - MySQL database PMDA

DESCRIPTION

       pmdamysql is a Performance Co-Pilot PMDA which extracts live performance data from a running MySQL database.

INSTALLATION

       pmdamysql uses a configuration file from (in this order):

       o   /etc/pcpdbi.conf

       o   $PCP_PMDAS_DIR/mysql/mysql.conf

       This file can contain overridden values (Perl code) for the settings listed at the start of pmdamysql.pl, namely:

       o   database name (see DBI(3) for details)

       o   database user name

       o   database pass word

       Once this is setup, you can access the names and values for the mysql performance metrics by doing the following as root:

	       # cd $PCP_PMDAS_DIR/mysql
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/mysql
	       # ./Remove

       pmdamysql is launched by pmcd(1) and should never be executed directly.	The Install and Remove scripts notify pmcd(1) when the agent is
       installed or removed.

Binary Status values in text
       Some of the status values are in the form of YES/NO or ON/OFF.

       Since these cannot be intepreted by tools like PMIE, they have been duplicated with a _num extension and the values of 1 (YES/ON) or 0
       (NO/OFF).

   Eg:
       o   mysql.slave_status.slave_io_running

       o   mysql.slave_status.slave_io_running_num

FILES

       /etc/pcpdbi.conf
	   configuration file for all PCP database monitors

       $PCP_PMDAS_DIR/mysql/mysql.conf
	   configuration file for pmdamysql

       $PCP_PMDAS_DIR/mysql/Install
	   installation script for the pmdamysql agent

       $PCP_PMDAS_DIR/mysql/Remove
	   undo installation script for the pmdamysql agent

       $PCP_LOG_DIR/pmcd/mysql.log
