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.
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.
I am trying to transpose tables listed in the format into format. Any help would be greatly appreciated.

test_data_1

grass-mysql - MySQL driver
MySQL driver MySQL driver in GRASS MySQL database driver in GRASS enables GRASS to store vector attributes in MySQL server.
Because vector attribute tables are created automaticaly when a new vector is written and the name of the table is the same as the name of
the vector it is good practice to create a new database for each GRASS mapset.
Creating a MySQL database
A new database is created within MySQL:
mysql> CREATE DATABASE mydb;
See the MySQL manual for details.
Driver and database name
GRASS modules require 2 parameters to connect to a database. Those parameters are 'driver' and 'database'. For MySQL driver the parameter
'driver' should be set to value 'mysql'. The parameter 'database' can be given in two formats:
Database name - in case of connection from localhost
String of comma separated list of kye=value options. Supported options are:
dbname - database name
host - host name or IP address
port - server port number
Examples of connection parameters:
db.connect driver=mysql database=mytest
db.connect driver=mysql database='dbname=mytest,host=test.grass.org'
Data types
GRASS supports almost all MySQL data types with following limitations:
Binary columns (BINARY, VARBINARY, TINYBLOB, MEDIUMBLOB, BLOB, LONGBLOB) are not not supported. If a table with binary col-
umn(s) is used in GRASS a warning is printed and only the supported columns are returned in query results.
Columns of type SET and ENUM are represented as string (VARCHAR).
Very large integers in columns of type BIGINT can be lost or corrupted because GRASS does not support 64 bin integeres on
most platforms.
GRASS does not currently distinguish types TIMESTAMP and DATETIME. Both types are in GRASS interpreted as TIMESTAMP.
Indexes
GRASS modules automaticaly create index on key column of vector attributes table. The index on key column is important for performance of
modules which update the attribute table, for example v.to.db, v.distance and v.what.rast.
Privileges
Because MySQL does not support groups of users and because only MySQL 'root' can grant privileges to other users GRASS cannot automaticaly
grant select privileges on created tables to group of users.
If you want to give privilege to read data from your mapset to other users you have to ask your MySQL server administrator to grant select
privilege to them on the MySQL database used for that mapset. For example, to allow everybody to read data in from your database 'mydb':
shell> mysql --user=root mysql
mysql> GRANT SELECT ON mydb.* TO ''@'%';
Schemas
Because MySQL does not support database schemas the parameter 'schema' of module db.connect should never be set to any value. If you set
that parameter for MySQL driver GRASS will try to write tables to the specified schema which will result in errors.
Groups
MySQL does not support user groups. Any settings specified by 'group' parameter of module db.connect are ignored by GRASS for MySQL driver.

Credits
Development of the driver was sponsored by Faunalia (Italy) as part of a project for ATAC.
