MYSQL 8 安装之02(創建數據庫及表空間)

1. 創建DB

[root@XAG8 data]# mysql.login
Enter password: 

[email protected] : (none)【11:12:44】5 SQL->CREATE DATABASE TESTDB;

[email protected] : (none)【11:12:47】6 SQL->SELECT DATABASE();
+------------+
| DATABASE() |
+------------+
| NULL       |
+------------+

[email protected] : (none)【11:13:02】7 SQL->use TESTDB;

[email protected] : TESTDB【11:13:30】8 SQL->SELECT DATABASE();
+------------+
| DATABASE() |
+------------+
| testdb     |
+------------+

[root@XAG8 testdb]# pwd
/usr/local/mysql/data/testdb
[root@XAG8 testdb]# ls

#創建通用表空間
[email protected] : TESTDB【11:22:31】18 SQL->
create tablespace testdb_ud ADD DATAFILE '/usr/local/mysql/data/testdb_ud.ibd' Engine=InnoDB;

#向通用表空間添加表
[email protected] : TESTDB【11:39:33】27 SQL->
create table t1 (aaa int,bbb varchar(10)) tablespace testdb_ud;

2. 創建分區表

create tablespace testdb201907 add datafile '/usr/local/mysql/data/testdb201907.ibd' Engine=InnoDB;

create tablespace testdb201908 add datafile '/usr/local/mysql/data/testdb201908.ibd' Engine=InnoDB;

create tablespace testdb201909 add datafile '/usr/local/mysql/data/testdb201909.ibd' Engine=InnoDB;

create tablespace testdb201910 add datafile '/usr/local/mysql/data/testdb201910.ibd' Engine=InnoDB;

[email protected] : TESTDB【05:09:20】49 SQL->
    create table t2_part
    (
     id int,
     creat_time datetime
    ) ENGINE=InnoDB PARTITION BY RANGE(TO_DAYS(creat_time))
    (
    PARTITION pl907 VALUES LESS THAN (TO_DAYS('2019-08-01')),
    PARTITION p1908 VALUES LESS THAN (TO_DAYS('2019-09-01')),
    PARTITION p1909 VALUES LESS THAN (TO_DAYS('2019-10-01'))
    );

[email protected] : TESTDB【06:00:27】114 SQL->
    create table t3_part
    (
     id int,
      creat_date date
    ) ENGINE=InnoDB PARTITION BY RANGE columns(creat_date)
    (
    PARTITION pl907 VALUES LESS THAN ('2019-08-01'),
    PARTITION p1908 VALUES LESS THAN ('2019-09-01'),
    PARTITION p1909 VALUES LESS THAN ('2019-10-01')
    );


[email protected] : TESTDB【06:17:34】139 SQL->create table t5_part
     (
      id int,
      creat_time datetime
     ) ENGINE=InnoDB PARTITION BY RANGE(TO_DAYS(creat_time))
     (
     PARTITION pl907 VALUES LESS THAN (TO_DAYS('2019-08-01')) TABLESPACE testdb201907,
     PARTITION p1908 VALUES LESS THAN (TO_DAYS('2019-09-01')) TABLESPACE testdb201908,
     PARTITION p1909 VALUES LESS THAN (TO_DAYS('2019-10-01')) TABLESPACE testdb201909
     );
ERROR 1478 (HY000): InnoDB : A partitioned table is not allowed in a shared tablespace.
#在MySQL 5.7.24中不支持将表分区添加到共享表空间，并在MySQL 8.0.13中删除了。 
#共享表空间包括InnoDB系统表空间和通用表空间。
