title: query in ADODB, dot il column name
body: <p>I'm trying query excel file in which I have column name "sth sth." 
  I get error cause ADODB doesn't like dot in name. So it should be like this:
  SELECT <code>sth sth.</code> FROM.
  I tried  SELECT <code>[sth sth.]</code> and  [<code>sth sth.</code>] and [sth sth.]
  But it doesn't work. Please help. Getting rid of dot is not an option.</p>
