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.
