copying translation into english language

Hi!
I met problems with language version of OpenERp and decided to switch into english version.

I have small database it is why i could have done on my own this simple step with 'description' field and my little knowledge of sql:

UPDATE product_template
SET description=(SELECT ir_translation.value
          FROM ir_translation
          WHERE product_template.id=ir_translation.res_id AND
                ir_translation.name='product.template,description' AND
                ir_translation.state='to_translate')
WHERE EXISTS (SELECT ir_translation.res_id
              FROM ir_translation
              WHERE product_template.id=ir_translation.res_id);

But my ask is (i am sure you all have done it already)
could you give me sql query which can copy translation strings (translated and to_translate)\into proper fields of proper tables using [ir_translation.name] filed?
Not as i did: ir_translation.name='product.template,description'
It was good for simple, one-time action.
This query is somewhat difficult for me (as i am not sql programmer) and you have it done, i suppose

Point is that i would like to have translated UI but the rest have working in 'english'.
