title: Python, Sqlite - Is there any way to neuter a condition in WHERE clause of a query?
body: <p>I have some Entry boxes on a form and a button that will search a db's table by executing a query that is composed of a <em>WHERE</em> clause with several conditions corresponding to the input boxes.
  The user may or may not fill all the input boxes, so I just want to have a predefined query with all columns on the where clause like:</p>
  
  <pre><code>column01=? AND column02=? AND ... AND columnN=?
  </code></pre>
  
  <p>and then have a tuple or list which simply I have constructed on a loop where inputed data is placed on the same order, columns of the WHERE clause were arranged and each input only checked whether it was <em>""</em> (not been input) and if so the respective place in the list would be assigned <strong><em>something</em></strong> that makes that specific condition transparent!. To clarify myself, see what means if user filled <strong>no</strong> input box (imagine that thing would be an <strong><em>asterisk</em></strong>):</p>
  
  <pre><code>"SELECT * FROM sometable WHERE column01=* AND ... AND columnN=*"  
  </code></pre>
  
  <p>that is desirable to work like this query:</p>
  
  <pre><code>"SELECT * FROM sometable"
  </code></pre>
  
  <p>which bears no constrain on any column. Is this credible? </p>
