MySQL如何快速插入大量數據
這幾天嘗試了使用不同的存儲引擎大量插入MySQL表數據，主要試驗了MyISAM存儲引擎和InnoDB。
下面是實驗過程： www.2cto.com
一、InnoDB存儲引擎。
創建數據庫和表
Sql代碼
CREATE DATABASE ecommerce;
CREATE TABLE employees (
id INT NOT NULL,
fname VARCHAR(30),
lname VARCHAR(30),
birth TIMESTAMP,
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 (10000),
partition p1 VALUES LESS THAN (50000),
partition p2 VALUES LESS THAN (100000),
partition p3 VALUES LESS THAN (150000),
Partition p4 VALUES LESS THAN MAXVALUE
);

創建存儲過程
Sql代碼
use ecommerce;
CREATE PROCEDURE BatchInsert(IN init INT, IN loop_time INT)
BEGIN
DECLARE Var INT;
DECLARE ID INT;
SET Var = 0;
SET ID = init;
WHILE Var < loop_time DO
insert into employees(id,fname,lname,birth,hired,separated,job_code,store_id) values(ID,CONCAT('chen',ID),CONCAT('haixiang',ID),Now(),Now(),Now(),1,ID);
SET ID = ID + 1;
SET Var = Var + 1;
END WHILE;
END;
調用存儲過程插入數據
Sql代碼
CALL BatchInsert（30036,200000）
用時：3h 37min 8sec
二、MyISAM存儲引擎
創建表
Sql代碼
use ecommerce;
CREATE TABLE ecommerce.customer (
id INT NOT NULL,
email VARCHAR(64) NOT NULL,
name VARCHAR(32) NOT NULL,
password VARCHAR(32) NOT NULL,
phone VARCHAR(13),
birth DATE,
sex INT(1),
avatar BLOB,
address VARCHAR(64),
regtime DATETIME,
lastip VARCHAR(15),
modifytime TIMESTAMP NOT NULL,
PRIMARY KEY (id)
)ENGINE = MyISAM ROW_FORMAT = DEFAULT
partition BY RANGE (id) (
partition p0 VALUES LESS THAN (100000),
partition p1 VALUES LESS THAN (500000),
partition p2 VALUES LESS THAN (1000000),
partition p3 VALUES LESS THAN (1500000),
partition p4 VALUES LESS THAN (2000000),
Partition p5 VALUES LESS THAN MAXVALUE
);
創建存儲過程
Sql代碼
use ecommerce;
DROP PROCEDURE IF EXISTS ecommerce.BatchInsertCustomer;
CREATE PROCEDURE BatchInsertCustomer(IN start INT,IN loop_time INT)
BEGIN
DECLARE Var INT;
DECLARE ID INT;
SET Var = 0;
SET ID= start;
WHILE Var < loop_time
DO
insert into customer(ID,email,name,password,phone,birth,sex,avatar,address,regtime,lastip,modifytime)
values(ID,CONCAT(ID,'@sina.com'),CONCAT('name_',rand(ID)*10000 mod 200),123456,13800000000,adddate('1995-01-01',(rand(ID)*36520) mod 3652),Var%2,'http://t3.baidu.com/it/u=2267714161,58787848&fm=52&gp=0.jpg','北京市海澱區',adddate('1995-01-01',(rand(ID)*36520) mod 3652),'8.8.8.8',adddate('1995-01-01',(rand(ID)
*36520) mod 3652));
SET Var = Var + 1;
SET ID= ID + 1;
END WHILE;
END;
調用存儲過程插入數據
Sql代碼
ALTER TABLE customer DISABLE KEYS;
CALL BatchInsertCustomer(1,2000000);
ALTER TABLE customer ENABLE KEYS;
用時：8min 50sec
通過以上對比發現對於插入大量數據時可以使用MyISAM存儲引擎，如果再需要修改MySQL存儲
引擎可以使用命令：
Sql代碼
ALTER TABLE t ENGINE = MYISAM;
