一、常用命令 1. 建立数据库DB2_GCB CREATE DATABASE DB2_GCB ON G: ALIAS DB2_GCB USING CODESET GBK TERRITORY CN COLLATE USING SYSTEM DFT_EXTENT_SZ 32 2. 数据库 connect to sample1 user db2admin using 8301206 3. 建立别名 create alias db2admin.tables for sysstat.tables; CREATE ALIAS DB2ADMIN.VIEWS FOR SYSCAT.VIEWS create alias db2admin.columns for syscat.columns; create alias guest.columns for syscat.columns; 4. 建立表 create table zjt_tables as (select * from tables) definition only; create table zjt_views as (select * from views) definition only; 5. 插入记录 insert into zjt_tables select * from tables; insert into zjt_views select * from views; 6. 建立视图 create view V_zjt_tables as select tabschema,tabname from zjt_tables; 7. 建立触发器 CREATE TRIGGER zjt_tables_del AFTER DELETE ON zjt_tables REFERENCING OLD AS O FOR EACH ROW MODE DB2SQL Insert into zjt_tables1 values(substr(o.tabschema,1,8),substr(o.tabname,1,10)) 8. 建立唯一性索引 CREATE UNIQUE INDEX I_ztables_tabname ON zjt_tables(tabname); 9. 查看表 select tabname from tables where tabname='ZJT_TABLES'; |
