2.1 PARTITION BY RANGE 分区方式 如果分区字段是连续的,比如日期类型,可以使用PARTITION BY RANGE分区方式。 CREATETABLEorders(order_idINT,order_dateDATE)PARTITIONBYRANGE(order_date)(PARTITIONp202001VALUESLESS THAN('2020-02-01'),PARTITIONp202002VALUESLESS THAN('2020-03-01'),PARTITIONp202003VALUESLESS THA...
下面是一种按日期分区表的方法: 创建一个新表,包含要进行分区的列和其他需要的列。 CREATE TABLE my_table ( id INT, date_column DATE, other_column VARCHAR(255), ... ) PARTITION BY RANGE(TO_DAYS(date_column)); 复制代码 创建分区 ALTER TABLE my_table PARTITION BY RANGE(TO_DAYS(date_column...
CREATE TABLE orders ( order_id INT NOT NULL AUTO_INCREMENT, order_date DATE NOT NULL, customer_id INT NOT NULL, total_amount DECIMAL(10,2), PRIMARY KEY (order_id, order_date) ) PARTITION BY RANGE COLUMNS(order_date) ( PARTITION p202201 VALUES LESS THAN ('2022-02-01'), PARTITION p20...
以Range方式为例，创建一个根据时间进行分区的表，语句示例如下：CREATE TABLE sales (id INT NOT NULL,sale_date DATE NOT NULL,product_id INT NOT NULL,units_sold INT NOT NULL,price DECIMAL(10, 2) NOT NULL,KEY (sale_date, product_id))PARTITION BY RANGE(sale_date)(PARTITION p0 VALUES LESS ...
ALTER TABLE zj_node_price ADD PRIMARY KEY (id,data_date); ALTER TABLE zj_node_price ADD INDEX u_data_date (data_date) alter table zj_node_price partition by range COLUMNS(data_date) ( partition p20241101 values less than ('2024-11-01'), ...
1) 创建range分区 create table emp (empnovarchar(20) not null , empnamevarchar(20), deptnoint, birthdatedate, salaryint ) partition by range(salary) ( partition p1 values less than (1000), partition p2 values less than (2000), partition p3 values less than maxvalue ...
hired DATE NOT NULL DEFAULT'1970-01-01', separated DATE NOT NULL DEFAULT'9999-12-31', job_code INT NOT NULL, store_id INT NOT NULL ) PARTITION BY RANGE (store_id) ( PARTITION p0 VALUES LESS THAN (6), PARTITION p1 VALUES LESS THAN (11), ...
