Oracle 的基本操作（2）

--建立使用者及授權

create user a_hr identified by 123456;
grant dba to a_hr;
create user a_oe identified by 123456;
grant dba to a_oe;
drop table stock_received --刪除該錶
--建立 stock_received 表，有 stock_id 、stock_date 和 cost 列。
--建立 myseq 序列，該序列的起始值為 1000，每次查詢增加10，直到該序列達到 1100，然後重新從 1000 開始
create table stock_received(
stock_id number not null,
stock_date date not null,
cost number not null
)create sequence myseq
minvalue 1000
maxvalue 1100
start with 1000
increment by 10
cache 10
cycle;
select myseq.nextval from dual;
--建立公有同義詞 p_stock_received ,並通過 a_oe 訪問
create public synonym p_stock_received for a_hr.stock_received; 
grant select on p_stock_received to a_oe;
select * from p_stock_received;--可以通過a_oe訪問
select * from a_hr.stock_received;--可以通過a_oe訪問
--將 stock_date 建立 3 個範圍分割槽
create table stock_received2  
partition by range(stock_date)  
(partition part2 values less than (to_date('2012/01/01','yyyy/mm/dd')),    
partition part3 values less than (to_date('2013/01/01','yyyy/mm/dd')),    
partition part4 values less than (to_date('2014/01/01','yyyy/mm/dd'))  
)  as select * from stock_received;  
--在 stock_id 列上建立唯一索引
create unique index idx_stock_id on stock_received(stock_id);
