+--------+

+--------+
1 row in set (0.01 sec)
```

```text
create table t1 (spID smallint,userID bigint,score int);
insert into t1 values (1,1,1);
insert into t1 values (2,2,2);
insert into t1 values (2,1,4);
insert into t1 values (3,3,3);
insert into t1 values (1,1,5);
insert into t1 values (4,6,10);

mysql> select userID,spID,score from t1 where spID>=userID*score;
