一、顯示當前實例sql

>> get instance

The current database manager instance is:  db2axing

二、列出當前實例中激活的數據庫數據庫

>> list active databases

        Active Databases
    Database name                       =LAISDB
    Applications connected currently    = 529
    Database path                       =/db2/laisdb/db2axing/NODE0000/SQL00001/MEMBER0000/

    Database name                       =WEBUAT
    Applications connected currently    = 2
    Database path                       =/db2/laisdb/db2axing/NODE0000/SQL00001/MEMBER0000/

三、鏈接數據庫app

>> connect to db2axing
 
        Database Connection Information
 
    Database server        = DB2/AIX64  10.5.8
    SQL authorization ID   = WEBUAT
    Local database alias   = WEBUAT

四、查看數據庫中全部的表spa

>> list tables

Table/View                      Schema          Type  Creation time             
------------------------------- --------------- ----- --------------------------

五、db2信息查詢命令code

>> db2 list tables 　　　　　　　　　　　　#列出全部表名
>> db2 describe table 表名 　　　　　　　　#顯示錶字段　
>> db2 list db directory                #列出該用戶建立的全部數據庫名
>> db2 list tablespaces show detail     #查看當前數據庫表空間分配情況
>> db2 list application
>> db2 list db directory               列出全部數據庫
>> db2 list active databases           列出全部活動的數據庫
>> db2 list tables for all             列出當前數據庫下全部的表
>> db2 list tables for schema btp      列出當前數據庫中schema爲btp的表
>> db2 list tablespaces show detail    顯示數據庫空間使用狀況
>> db2 list packages for all

顯示當前的實例orm

 
         [db2inst1@localhost ~]$ db2 get instance 
        
         The  
         current  
         database  
         manager instance
