title: Mysql - Operation like IN which matches all values
body: <p>I have a table Orders which contains CustID and BookNo of customers who have ordered Books.
  I have another table Books which contains all the BookNo. </p>
  
  <p>I want to display all CustIDs who have ordered all the BookNo. </p>
  
  <p>Something like the 'IN' function which matches all values in the set as 'AND' instead of 'OR' would be handy.</p>
  
  <p>Any quick clues, if not an answer? </p>
