1、创建数据库
2

CREATE DATABASE frk
3

AUTOMATIC STORAGE NO ON
4

'C:\' USING CODESET UTF-8 TERRITORY CN COLLATE
5

USING SYSTEM PAGESIZE 32768
6

CATALOG TABLESPACE MANAGED BY DATABASE
7

USING ( FILE 'E:\db2 data\frksysdectablespace' 51200 )
8

USER TABLESPACE MANAGED BY DATABASE
9

USING ( FILE 'E:\db2 data\frksysusertablespace' 51200 )
10

TEMPORARY TABLESPACE MANAGED BY DATABASE
11

USING ( FILE 'E:\db2 data\frksystemptablespace' 51200 ) ;
12

2、创建缓冲池
13

CONNECT TO FRK;
14

CREATE BUFFERPOOL BUFFER1 IMMEDIATE SIZE 250 PAGESIZE 32 K ;
15

CREATE BUFFERPOOL BUFFER2 IMMEDIATE SIZE 250 PAGESIZE 32 K ;
16

CREATE BUFFERPOOL BUFFER3 IMMEDIATE SIZE 250 PAGESIZE 32 K ;
17

CREATE BUFFERPOOL BUFFER4 IMMEDIATE SIZE 250 PAGESIZE 32 K ;
18

CONNECT RESET;
19

3、创建表空间
20

CONNECT TO FRK;
21

CREATE REGULAR TABLESPACE FRKREGTABLESPACE PAGESIZE 32 K MANAGED BY DATABASE USING ( FILE 'E:\db2 data\frkregtablespacedata' 16000 ) EXTENTSIZE 16 OVERHEAD 10.5 PREFETCHSIZE 16 TRANSFERRATE 0.14 BUFFERPOOL BUFFER1 DROPPED TABLE RECOVERY ON;
22

CREATE SYSTEM TEMPORARY TABLESPACE FRKSYSTEMPTSPACE PAGESIZE 32 K MANAGED BY DATABASE USING ( FILE 'E:\db2 data\frmsystemtablespacedata' 6400 ) EXTENTSIZE 16 OVERHEAD 10.5 PREFETCHSIZE 16 TRANSFERRATE 0.14 BUFFERPOOL BUFFER2 ;
23

CREATE USER TEMPORARY TABLESPACE FRKUSERTEMPTSPACE PAGESIZE 32 K MANAGED BY DATABASE USING ( FILE 'E:\db2 data\frkusertemptablespacedata' 6400 ) EXTENTSIZE 16 OVERHEAD 10.5 PREFETCHSIZE 16 TRANSFERRATE 0.14 BUFFERPOOL BUFFER3 ;
24

CREATE LARGE TABLESPACE FRKLAGGERTSPACE PAGESIZE 32 K MANAGED BY DATABASE USING ( FILE 'E:\db2 data\frkloggertablespacedata' 16000 ) EXTENTSIZE 16 OVERHEAD 10.5 PREFETCHSIZE 16 TRANSFERRATE 0.14 BUFFERPOOL BUFFER4 ;
25

CONNECT RESET;
26

4、创建表
27

CREATE TABLE abc(
28

id integer NOT NULL ,
29

name VARCHAR(180))
30

IN FRKREGTABLESPACE;
31

]]>DB2中创建数据库和表的过程http://www.blogjava.net/linder/articles/336864.html麟德麟德Tue, 02 Nov 2010 13:50:00 GMThttp://www.blogjava.net/linder/articles/336864.htmlhttp://www.blogjava.net/linder/comments/336864.htmlhttp://www.blogjava.net/linder/articles/336864.html#Feedback0http://www.blogjava.net/linder/comments/commentRss/336864.htmlhttp://www.blogjava.net/linder/services/trackbacks/336864.html 1

1、用户可以通过DB2的工具创建数据库
2

2、创建缓冲层一般建三个32K页的缓冲池
3

3、创建三个表空间，系统表空间、用户表空间、常规表空间，这三个表空间分别使用刚才创建的缓冲池
4

4、创建数据库表
5

（1）无主键
6

create table helpDoConfg
7

(
8

ID INTEGER ,
9

IP VARCHAR(16),
10

PORT VARCHAR(8),
11

projectName VARCHAR(16)
12

) in webwfuserspace;
13

（2）主键自增长但不控制起点
14

create table helpDoConfg
15

(
16

ID INTEGER not null generated as identity,
17

IP VARCHAR(16),
18

PORT VARCHAR(8),
19

projectName VARCHAR(16)
20

) in webwfuserspace;
21

（3）主键自增长控制起点
22

create table helpDoConfg
23

(
24

ID INTEGER NOT NULL GENERATED BY DEFAULT AS IDENTITY (START WITH 20000, INCREMENT BY 1, CACHE 20, NO CYCLE,
25

NO ORDER),
27

IP VARCHAR(16),
28

PORT VARCHAR(8),
29

projectName VARCHAR(16)
30

) in webwfuserspace;
