DB2的常用命令

介紹一些DB2的常用命令，希望對初學者有幫助。
1．啟動資料庫
      db2start
2．停止資料庫
      db2stop
3．連接資料庫
      db2 connect to o_yd user db2 using pwd
4．讀資料庫管理程式配置
      db2 get dbm cfg
5．寫資料庫管理程式配置
      db2 update dbm cfg using 參數名 參數值
6．讀資料庫的配置
      db2 connect to o_yd user db2 using pwd
      db2 get db cfg for o_yd
7．寫資料庫的配置
      db2 connect to o_yd user db2 using pwd
      db2 update db cfg for o_yd using 參數名 參數值
8．關閉所有應用連接
      db2 force application all
      db2 force application ID1,ID2,,,Idn MODE ASYNC
      (db2 list application for db o_yd show detail)
9．備份資料庫
      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．恢復資料庫
     db2 restore db o_yd from d: to d:
     db2 restore db o_yd from \\.\tape0 to d:
11．綁定存儲過程
    db2 connect to o_yd user db2 using pwd
    db2 bind c:\dfplus.bnd
   拷貝存儲過程到伺服器上的C:\sqllib\function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．匯出表數據
      db2 export to c:\dftz.txt of del select * from dftz
      db2 export to c:\dftz.ixf of ixf select * from dftz
14．導入表數據
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．執行一個批次檔
        db2 –tf 批次檔名
       （文件中每一條命令用 ；結束）
16．自動生成批次檔
      建文字檔：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
在伺服器上：C:\sqllib\misc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
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. 顯示當前使用者所有表

  list tables
22.列出所有的系統表

  list tables for system
23.查看表結構
  db2 describe select * from user.tables
