Linux下DB2指令總結

1、顯示當前實例

>> get instance

The current database manager instance is:  db2axing

2、列出當前實例中激活的數據庫

>> 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/

3、連接數據庫

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

4、查看數據庫中所有的表

>> list tables

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

5、db2信息查詢命令

>> db2 list tables 　　　　　　　　　　　　#列出所有表名
>> db2 describe table 表名 　　　　　　　　#顯示表字段　
>> db2 list db directory                #列出該用戶創建的所有數據庫名
>> db2 list tablespaces show detail     #查看當前數據庫表空間分配狀況
>> db2 list application
>> db2 list db directory               列出所有數據庫
>> db2 list active databases           列出所有活動的數據庫
>> db2 list tables for all             列出當前數據庫下所有的表
