mysql innodb單錶分割槽實戰

目的：為了了解mysql單錶分割槽方法，特此作為學習筆記記錄一下。

一。準備表，建立乙個學生表，包含主鍵sid和名稱sname欄位

create table students(

sid int(5) primary key,

sname varchar(24)

);二。準備資料

insert into students(sid,sname) values(10003,'tom');

insert into students(sid,sname) values(10005,'jerry');

insert into students(sid,sname) values(10006,'hengte');

insert into students(sid,sname) values(10007,'weilian');

insert into students(sid,sname) values(10000,'tom1');

insert into students(sid,sname) values(10001,'jerry2');

insert into students(sid,sname) values(10002,'hengte3');

insert into students(sid,sname) values(10004,'weilian4');

三。查詢結果

select * from sutdents

四。建立分割槽，按照主鍵id的值進行設定分割槽規則如下：

alter table students partition by range(sid)

(partition p0 values less than (10001),

partition p1 values less than (10003),

partition p2 values less than (10005),

partition p3 values less than maxvalue

);五。查詢結果，可以看到查詢結果分布到不同的分割槽裡

select  * from students partition (p0);

select  * from students partition (p1);

select  * from students partition (p2);

select  * from students partition (p3);

六。驗證新插入資料

insert into students(sid,sname) values(10011,'tom12');

insert into students(sid,sname) values(10012,'jerry13');

insert into students(sid,sname) values(10013,'hengte14');

insert into students(sid,sname) values(10014,'weilian15');

insert into students(sid,sname) values(10015,'tom116');

insert into students(sid,sname) values(10016,'jerry22');

insert into students(sid,sname) values(10017,'hengte32');

insert into students(sid,sname) values(10018,'weilian42');

七。再次查詢分割槽資料，會看到新插入的資料按照分割槽規則劃分到對應的分割槽裡了

select  * from students partition (p0);

select  * from students partition (p1);

select  * from students partition (p2);

select  * from students partition (p3);
