DB2数据库命令简介

1．启动数据库

db2start

2．停止数据库

db2stop

3．连接数据库

db2 connect to o_yd user db2 using pwd

4．读数据库管理程序配置

db2 get dbm cfg

5．写数据库管理程序配置

db2 update dbm cfg using 参数名 参数值

6．读数据库的配置

db2 connect to o_yd user db2 using pwd

db2 get db cfg for o_yd

7．写数据库的配置

db2 connect to o_yd user db2 using pwd

db2 update db cfg for o_yd using 参数名 参数值

8．关闭所有应用连接

db2 force application all

db2 force application ID1,ID2,,,Idn MODE ASYNC

(db2 list application for db o_yd show detail)

9．备份数据库

db2 force application all

db2 backup db o_yd to d:

(db2 initialize tape on \\.\tape0)

(db2 rewind tape on \\.\tape0)

db2 backup db o_yd to \\.\tape0

10．恢复数据库

db2 restore db o_yd from d: to d:

db2 restore db o_yd from \\.\tape0 to d:

11．绑定存储过程

db2 connect to o_yd user db2 using pwd

db2 bind c:\dfplus.bnd

拷贝存储过程到服务器上的C:\sqllib\function目录中

12．整理表

db2 connect to o_yd user db2 using pwd

db2 reorg table ydd

db2 runstats on table ydd with distribution and indexes all

13．导出表数据

db2 export to c:\dftz.txt of del select * from dftz

db2 export to c:\dftz.ixf of ixf select * from dftz

14．导入表数据

import from c:\123.txt of del  insert into ylbx.czyxx

db2 import to c:\dftz.txt of del commitcount 5000 messages  c:\dftz.msg insert into dftz

db2 import to c:\dftz.ixf of ixf commitcount 5000 messages c:\dftz.msg insert into dftz

db2 import to c:\dftz.ixf of ixf commitcount 5000 insert into dftz

db2 import to c:\dftz.ixf of ixf commitcount 5000 insert_update into dftz

db2 import to c:\dftz.ixf of ixf commitcount 5000 replace into dftz

db2 import to c:\dftz.ixf of ixf commitcount 5000 create into dftz   (仅IXF)

db2 import to c:\dftz.ixf of ixf commitcount 5000 replace_create into dftz  (仅IXF)

15．执行一个批处理文件

db2 -tf 批处理文件名

（文件中每一条命令用 ；结束）

16．自动生成批处理文件

建文本文件：temp.sql

select 'runstats on table DB2.' || tabname || '

with distribution and  detailed indexes all;'

from syscat.tables where tabschema='DB2' and type='T';

db2 -tf temp.sql>runstats.sql

17．自动生成建表（视图）语句

在服务器上：C:\sqllib\misc目录中

db2 connect to o_yd user db2 using pwd

db2look -d o_yd -u db2 -e -p -c c:\o_yd.txt

18．其他命令

grant dbadm on database to user bb

19select * from czyxx fetch first 1 rows only

20db2look -d ylbx -u db2admin -w -asd -a -e -o a.txt21. 显示当前用户所有表

　　list tables

22.列出所有的系统表

　　list tables for system

23.查看表结构

　　db2 describe select * from user.tables
