Answer 1

if you want to insert data in core_onfig_data

just use like below using installer script

<?php

$installer = $this;

$installer->startSetup();

$installer->run("

INSERT INTO {$this->getTable('core_config_data')} (scope_id,scope,path,value) values (0,'default','groupname/sectionname/fieldname','your value');


");

$installer->endSetup();

?>

Add more variable as you want.

OR Alternate way

If you are developing an extension, you can configure your field for administration using system.xml. The xpath will be catalog/groups/seo/fields/your_field (ref. Mage/Catalog/etc/system.xml).

To set a default for this value, you can either add the value to your module's config.xml using the xpath groupname/sectionname/fieldname, or you can create an install script which will write the value to core_config_data.
