http://www.nowcoder.com/practice/9681abf28745468c8adacb3b029a18ce
插入记录的方式汇总：
- 普通插入（全字段）：INSERT INTO table_name VALUES (value1, value2, ...)
- 普通插入（限定字段）：INSERT INTO table_name (column1, column2, ...) VALUES (value1, value2, ...)
- 多条一次性插入：INSERT INTO table_name (column1, column2, ...) VALUES (value1_1, value1_2, ...), (value2_1, value2_2, ...), ...
- 从另一个表导入：INSERT INTO table_name SELECT * FROM table_name2 [WHERE key=value]
insert into exam_record_before_2021(uid, exam_id,start_time,submit_time, score)
select uid,exam_id,start_time,submit_time,score
from exam_record
where submit_time < '2021-01-01';
