title: when to use clustered index and when to use nonclustered index
body: <p><br/></p>
  
  <p>Thanks for giving the time to read my question .<br/>
  i have a question in my mind that <br/>
  <code>**when we should use clustered and nonclustered index**</code>.<br/>
  i have searched on the internet and found that clustered index is much <br/>
  faster than the nonclustered index. 
  but i am confused about the usage circumstances .<br/>
  can you please tell me when we should use clustered and when we should <br/>
   use nonclustered index.<br/>
  Looking for your kind help.<br/></p>
  
  <p>Thanks in advance .<br/>
