DB2常用的命令
1．启动数据库
db2start
2．停止数据库
db2stop
3．连接数据库
db2 connect to oyd user db2 using pwd
(注：oyd为数据库名)
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
