SELECT count(*), avg(b) FROM t2 WHERE b>=9800 AND b<10800;
SELECT count(*), avg(b) FROM t2 WHERE b>=9900 AND b<10900;

Test 5: 100 SELECTs on a string comparison

SELECT count(*), avg(b) FROM t2 WHERE c LIKE '%one%';
SELECT count(*), avg(b) FROM t2 WHERE c LIKE '%two%';

Test 6: INNER JOIN without an index

SELECT t1.a FROM t1 INNER JOIN t2 ON t1.b=t2.b;

Test 7: Creating an index

CREATE INDEX i2a ON t2(a);
CREATE INDEX i2b ON t2(b);
