title: Teradata SQL parameter syntax
body: <p>Is there syntax which allows a parameter marker in the middle of a table name? For example, consider the queries</p>
  
  <pre><code>    sel * from t?x
  </code></pre>
  
  <p>and</p>
  
  <pre><code>    sel * from t?x_blah.
  </code></pre>
  
  <p>Both execute as </p>
  
  <pre><code>    sel * from t1
  </code></pre>
  
  <p>if the user inputs 1. In the first query <code>x = 1</code> and in the second query <code>x_blah = 1</code>. I would like to modify the second query to set <code>x = 1</code> and execute as</p>
  
  <pre><code>    sel * from t1_blah.
  </code></pre>
  
  <p>Is there a way to do this?</p>
  
  <p>Thanks!</p>
