Database changed
drizzle> create table t1 (a int, b int, c int);
Query OK, 0 rows affected (0.00 sec)

drizzle> create table t2 (d int);
Query OK, 0 rows affected (0.01 sec)

drizzle> create table t3 (a1 int, b1 int, c1 int);
Query OK, 0 rows affected (0.01 sec)

drizzle> insert into t1 values(1,2,3);
