title: IN condition is not working when the data is like 'Test','Test' from a result query
body: <p>In one table I have a data like 'Test1','Test2' for one column. Why I can not use this column data in one more select query with IN condition.</p>
  
  <pre><code>Example:
  
  Table TESTING2:
  
  AREA_NAME
  -------------------------------
  'Tilaknagar','Kadubeesinahalli'
  
  Table TESTING1:
  
  NAME    AREA
  ----    ----------------
  Ravi    Tilaknagar
  Ram     Kadubeesinahalli
  </code></pre>
  
  <p>If I write query</p>
  
  <pre><code>SELECT *
  FROM TESTING1
  WHERE AREA IN (SELECT AREA_NAME FROM TESTING2);
  </code></pre>
  
  <p>is not working. How to make this one to work.</p>
