以下的文章主要描述的是DB2數(shù)據(jù)庫在linux操作系統(tǒng)下的相關(guān)指令，你如果對DB2數(shù)據(jù)庫在linux操作系統(tǒng)下的相關(guān)指令有興趣的話你就可以點(diǎn)擊以下的文章進(jìn)行觀看了，以下就是文章的詳細(xì)內(nèi)容介紹，望大家借鑒。

DB2數(shù)據(jù)庫命令簡介

1．啟動數(shù)據(jù)庫

DB2start

2．停止數(shù)據(jù)庫

DB2stop

DB2數(shù)據(jù)庫在linux相關(guān)指令之3．連接數(shù)據(jù)庫

DB2 connect to o_yd user DB2 using pwd

4．讀數(shù)據(jù)庫管理程序配置

DB2 get dbm cfg

5．寫數(shù)據(jù)庫管理程序配置

DB2 update dbm cfg using 參數(shù)名 參數(shù)值

6．讀數(shù)據(jù)庫的配置

DB2 connect to o_yd user DB2 using pwd

DB2 get db cfg for o_yd

7．寫數(shù)據(jù)庫的配置

DB2 connect to o_yd user DB2 using pwd

DB2 update db cfg for o_yd using 參數(shù)名 參數(shù)值

8．關(guān)閉所有應(yīng)用連接

DB2 force application all

DB2 force application ID1,ID2,,,Idn MODE ASYNC

(DB2 list application for db o_yd show detail)

9．備份數(shù)據(jù)庫

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．恢復(fù)數(shù)據(jù)庫

DB2 restore db o_yd from d: to d:

DB2 restore db o_yd from \.tape0 to d:

DB2數(shù)據(jù)庫在linux相關(guān)指令之11．綁定存儲過程

DB2 connect to o_yd user DB2 using pwd

DB2 bind c:dfplus.bnd

拷貝存儲過程到服務(wù)器上的C:sqllibfunction目錄中

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．導(dǎo)出表數(shù)據(jù)

DB2 export to c:dftz.txt of del select * from dftz

DB2 export to c:dftz.ixf of ixf select * from dftz

14．導(dǎo)入表數(shù)據(jù)

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 (僅IXF)

DB2 import to c:dftz.ixf of ixf commitcount 5000 replace_create into dftz (僅IXF)

15．執(zhí)行一個批處理文件

DB2 -tf 批處理文件名

（文件中每一條命令用 ；結(jié)束）

16．自動生成批處理文件

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．自動生成建表（視圖）語句

在服務(wù)器上：C:sqllibmisc目錄中

DB2 connect to o_yd user DB2 using pwd

DB2look -d o_yd -u DB2 -e -p -c c:o_yd.txt

DB2數(shù)據(jù)庫在linux相關(guān)指令之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. 顯示當(dāng)前用戶所有表

list tables

22.列出所有的系統(tǒng)表

list tables for system

23.查看表結(jié)構(gòu)

DB2 describe select * from user.tables
