Mysql数据库导入千万条数据

第一步 创建数据库

sql语句:

CREATE DATABASE aaaa

第二步 创建表

sql语句:

CREATE TABLE usertb(
id serial,
uname  varchar(20) ,
ucreatetime  datetime  ,
age  int(11))
ENGINE=MYISAM
DEFAULT CHARACTER SET=utf8 COLLATE=utf8_general_ci
AUTO_INCREMENT=1
ROW_FORMAT=COMPACT;

第三步 创建插入数据存储过程

sql语句:

DELIMITER $$
SET AUTOCOMMIT = 0$$
CREATE  PROCEDURE test1()
BEGIN
DECLARE v_cnt DECIMAL (10)  DEFAULT 0 ;
dd:LOOP
        INSERT  INTO usertb VALUES
        (NULL,'用户1','2010-01-01 00:00:00',20),
        (NULL,'用户2','2010-01-01 00:00:00',20),
        (NULL,'用户3','2010-01-01 00:00:00',20),
        (NULL,'用户4','2010-01-01 00:00:00',20),
        (NULL,'用户5','2011-01-01 00:00:00',20),
        (NULL,'用户6','2011-01-01 00:00:00',20),
        (NULL,'用户7','2011-01-01 00:00:00',20),
        (NULL,'用户8','2012-01-01 00:00:00',20),
        (NULL,'用户9','2012-01-01 00:00:00',20),
        (NULL,'用户0','2012-01-01 00:00:00',20)
                ;
        COMMIT;
        SET v_cnt = v_cnt+10 ;
            IF  v_cnt = 10000000 THEN LEAVE dd;
            END IF;
        END LOOP dd ;
END;$$
DELIMITER ;

第四步 执行存储过程

执行sql语句

call test1;
