  • Two for the price of one

    Haven’t done any sneaky puzzles in a while. How would you accomplish this?

    mysql> CREATE TABLE t1 (id int);
    Query OK, 0 rows affected (0.08 sec)
    
    mysql> INSERT INTO t1 VALUES (1);
    Query OK, 1 row affected (0.02 sec)
    
    mysql> SELECT COUNT(*) FROM t1;
    +----------+
    | COUNT(*) |
    +----------+
    |        2 |
    +----------+
    1 row in set (0.00 sec)
