1. 創建一個用戶，並為該用戶分配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,
