DB2数据库命令简介 1.启动数据库 DB2start 2.停止数据库 DB2stop DB2数据库在linux相关指令之3.连接数据库 DB2 connect to o_yd user DB2 using pwd 4.读数据库管理程序配置 DB2 get dbm cfg 5.写数据库管理程序配置 DB2 update dbm cfg using 参数名 参数值 6.读数据库的配置 DB2 connect to o_yd user DB2 using pwd DB2 get db cfg for o_yd 7.写数据拦旁库的配置 DB2 connect to o_yd user DB2 using pwd DB2 update db cfg for o_yd using 参数名 参数值 8.关闭所有应用连接 DB2 force application all DB2 force application ID1,ID2,,,Idn MODE ASYNC (DB2 list application for db o_yd show detail) 9.备份数据库 DB2 force application all DB2 backup db o_yd to d: (DB2 initialize tape on 慧闷.tape0) (DB2 rewind tape on .tape0) DB2 backup db o_yd to .tape0 10.恢复数据库 DB2 restore db o_yd from d: to d: DB2 restore db o_yd from .tape0 to d: DB2数据库在linux相关指令之11.绑定存储过程 DB2 connect to o_yd user DB2 using pwd DB2 bind c:dfplus.bnd 拷贝存储过程到服务器上的C:sqllibfunction目录中 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.导出表数据 DB2 export to c:dftz.txt of del select * from dftz DB2 export to c:dftz.ixf of ixf select * from dftz 14.导入表数据 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 (仅IXF) DB2 import to c:dftz.ixf of ixf commitcount 5000 replace_create into dftz (仅IXF) 15.执行一个批处理文件 DB2 -tf 批处理文件名 (文件中每一条命令用 ;结束) 16.自动生成批处前衡弯理文件 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.自动生成建表(视图)语句 在服务器上:C:sqllibmisc目录中 DB2 connect to o_yd user DB2 using pwd DB2look -d o_yd -u DB2 -e -p -c c:o_yd.txt DB2数据库在linux相关指令之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. 显示当前用户所有表 list tables 22.列出所有的系统表 list tables for system 23.查看表结构 DB2 describe select * from user.tables (实习编辑:HJ)
