DB2基本命令

1．啓動數據庫
      db2start
2．停止數據庫
      db2stop
3．連接數據庫
      db2 connect to o_yd user db2 using pwd
4．讀數據庫管理程序配置
      db2 get dbm cfg
5．寫數據庫管理程序配置
      db2 update dbm cfg using 參數名 參數值
6．讀數據庫的配置
      db2 connect to o_yd user db2 using pwd
      db2 get db cfg for o_yd
7．寫數據庫的配置
      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．備份數據庫
      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．恢復數據庫
         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
   拷貝存儲過程到服務器上的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．導出表數據
          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．執行一個批處理文件
        db2 –tf 批處理文件名
       （文件中每一條命令用 ；結束）
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&#59;' from syscat.tables where tabschema='DB2' and type='T'&#59;
         db2 –tf temp.sql>;runstats.sql
17．自動生成建表（視圖）語句
         在服務器上：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
19．select * from czyxx fetch first 1 rows only
20．db2look –d ylbx –u db2admin –w –asd –a –e –o a.txt21 . 顯示當前用戶所有表
　　list tables
22．列出所有的系統表
　　list tables for system
23．查看錶結構
　　db2 describe select * from user.tables
