I found an old thread where a solution was posted for global changes to attribute image.
Here is the sql patch:

UPDATE products_attributes SET attributes_image = 'attribute_image.jpg' WHERE options_id = XXX and options_values_id = XXX;

What would be the field name used for the attribute price change?
Something like:

UPDATE products_attributes SET attributes_price = 15.00 WHERE options_id = XXX and options_values_id = XXX;

Thank for the help.
