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)
