title: ISDATE Function in Oracle
body: <p>I am developing a web application which is getting data from an Oracle DB. The select statements are created dynamically. What I want to do is, whenever I select a date field in a table, it should return it to a string with the format of dd.mm.yyyy</p>
  
  <p>what I need is basically a way to have a function like isdate(COLUMN_NAME, true stmt, false stmt)</p>
  
  <pre><code>SELECT ISDATE(First Column, to_char(FirstColumn,'dd.mm.yyyy'), FistColumn)
    FROM ANYTABLE
  </code></pre>
  
  <p>is there a way for this?</p>
