+| tweet_id | content                           |
++----------+-----------------------------------+
+| 1        | Let us Code                       |
+| 2        | More than fifteen chars are here! |
++----------+-----------------------------------+
+Output: 
++----------+
+| tweet_id |
++----------+
+| 2        |
