title: Start querying on a certain row criteria
body: <p>I have a mysql table which columns are post_id and post_msg. Now I want to query starting from a row that has a value of 3 in its post_id column. As a result of this query all the rows starting from post_id 3 (ASC) will be the result set.
  How can i do this?</p>
  
  <pre><code> post_id | post_msg   
     1     |   heheh   
     2     |   hi   
     3     |   hello 
     4     |   hoho  
     5     |   hayhay   
     6     |   harhar
  </code></pre>
  
  <p>from that table i want to query starting to a row that has a post_id that its value is 3
  I know to use LIMIT but my requirement is really to use the post_id for some reasons.
  Is this possible?</p>
