具体操作步骤
1. 创建分区表
```sql
CREATE TABLE orders (
order_id INT,
customer_id INT,
order_date DATE
)
PARTITION BY RANGE (YEAR(order_date)) (
PARTITION p0 VALUES LESS THAN (2000),
PARTITION p1 VALUES LESS THAN (2010),
PARTITION p2 VALUES LESS THAN (2020),
PARTITION p3 VALUES LESS THAN MAXVALUE
);
#### 2. 插入数据
```markdown
```sql
INSERT INTO orders (order_id, customer_id, order_date) VALUES (1, 1001, '2021-01-01');
INSERT INTO orders (order_id, customer_id, order_date) VALUES (2, 1002, '2015-06-15');
INSERT INTO orders (order_id, customer_id, order_date) VALUES (3, 1003, '2005-11-30');
#### 3. 分区查询
```markdown
```sql
SELECT * FROM orders PARTITION (p1);
