USING CODESET GBK TERRITORY CN COLLATE USING SYSTEM DFT_EXTENT_SZ 32

2. 连接数据库

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

[size=3]ON zjt_tables(tabname);

9. 查看表

select tabname from tables

where tabname=ZJT_TABLES;
