1. 創建一個用戶，并為該用戶分配create權限，分配表空間：
create user scott identified by tiger;
grant create session to scott;

grant create table to scott;

alter user scott default tablespace users;

alter user scott quota 512m on users;

2. 查找where條件指定的用戶為owner的所有表名稱：
select owner, table_name from dba_tables where owner='scott';

3. 在某一指定的表上創建指定參數的索引。
create index ind_test on test(x) tablespace users storage
(initial 2k
next 2k
minextents 1
maxextents 100
pctincrease 0);

4. 查看指定用戶為owner的索引名稱：
select index_name, table_owner from dba_indexes where owner='scott';

5. 查看指定表上的所有索引信息：
select index_owner, index_name, column_name from dba_ind_columns where table_name='scott';

6. 創建序列：
create s
incremen
start wi
maxvalue
cycle;

7. 使用序列：
insert into scott.test
values(staff_id.nextval,
'test')；

8. 查看表空間信息：
select * from dba_tablespaces；

9. 查看當前在線用戶：
select username from v$session;

10. how can i compile and link my application?
answer:
compiling and linking are very platform specific. your system-specific oracle
documentation has instructions on how to link a pro*c/c++ application. on unix
systems, there is a makefile called proc.mk in the demo directory. to link, say, the
demo program sample1.pc, you would enter the command line
make -f proc.mk sample1
if you need to use special precompiler options, you can run pro*c/c++ separately,
then do the make. or, you can create your own custom makefile. for example, if
your program contains embedded pl/sql code, you can enter
proc cv_demo userid=scott/tiger sqlcheck=semantics
make -f proc.mk cv_demo
on vms systems, there is a script called lnproc that you use to link your
pro*c/c++ applications.
