title: SQLite - Inserting values from multiple rows in the same table into a single row in another table
body: <p>I have a table of phone numbers (tblPhoneNumbers):
  ID, UserID, PhoneNumber</p>
  
  <p>and I need to move them into a Users table (tblUsers) that contains:
  ID, PhoneNumber1, PhoneNumber2</p>
  
  <p>tblPhoneNumbers is assumed to have 2 rows for every user. Is it possible to move the PhoneNumber value of the first row into PhoneNumber1, and the PhoneNumber value of the second row into PhoneNumber2?</p>
  
  <p>Essentially this is reverse-normalization but this is the task I need help with.
  Thanks!</p>
  
  <p>I need to use SQLite so I cannot use any syntax not available to SQLite.</p>
