title: Column name with symbols
body: <p>I want column names with symbols
    i.e. <code>{ImportId:week}</code></p>
  
  <p>I tried placing a " on either side of each symbol and string
    i.e. <code>"{""ImportId"":""week""}"</code> like this` </p>
  
  <pre><code>CREATE TABLE EXAMPLE
  (
  "{""ImportId"":""week""}" VARCHAR2(100)
  )
  </code></pre>
  
  <p>but I get the error:</p>
