Re: cannot query a table..

[Phillip Ward]

Short answer - backticks (`).
It's a symbol that looks a bit like a single quote, and can usually be found on a button next to the "1" on your keyboard. Wrap you dodgy identifiers in this, as in:

select id, lang, `from`, `to` 
from lang_translation ;

"Unfortunately I cant change the column names"
Why not?
Is this part of some package that you've acquired?

As you've discovered, using reserved words for column/ table names is a terrible idea. If you have any scope to change this, I'd recommend doing so.
