  --To create Table:
  CREATE TABLE celebs (
     id INTEGER, 
     name TEXT, 
     age INTEGER
  );
  
  --Inserting Some value
  INSERT INTO celebs (id, name, age) 
  VALUES (1, 'Justin Bieber', 22);
  
  --Alter table to enter new column PS: SQLite allows only column no rown, use insert for that otherwise
  ALTER TABLE celebs 
  ADD COLUMN twitter_handle TEXT;
  
  --NULL is a special value in SQL that represents missing or unknown data. Here, the rows that existed before the column was added have NULL (∅) values for twitter_handle.
  
  --Update
  --The UPDATE statement edits a row in a table. You can use the UPDATE statement when you want to change existing records.
  
  UPDATE celebs 
  SET twitter_handle = '@taylorswift13' 
  WHERE id = 4;
