oracle 创建表table:
create table abin1(
id number(20,0) not null,
name varchar2(100)not null,
pwd nvarchar2(100) not null,
create_time date,
constraint pk_abin1 primary key(id)
)
oracle创建索引(index):
create index myname on abin1(name);
oracle创建序列sequence:
create sequence abin1_seq
minvalue 1
maxvalue 999999999
start with 1
increment by 1
cache 20;
创建触发器:
create or replace trigger abin1_tri
before insert on abin1
for each row
begin
select abin1_seq.nextval into :new.id from dual;
end;
测试一条记录:
insert into abin1 (name,pwd,create_time) values ('abin','lee',sysdate);
呵呵,这里插入了数据,主键自增了,说明成功了。
创建存储过程procedure:
create or replace procedure abin1_pro
is
cursor mycur is select t.* from abin1 t;
abin mycur%rowtype;
begin
open mycur;
loop
fetch mycur into abin;
if(abin.name='abin')then
update abin1 t set t.name='abining',t.pwd=abin.pwd,t.create_time=sysdate where t.id=abin.id;
commit;
end if;
exit when mycur%NOTFOUND;
end loop;
if(mycur%ISOPEN)then
close mycur;
end if;
end;
测试存储过程示例:
declare
begin
abin1_pro;
end;
创建oracle函数function:
create or replace function abin_func
return number
is
total number;
begin
select count(1) into total from abin1 t;
return(total);
end;
创建测试函数示例:
declare
total number;
begin
total:=abin_func;
dbms_output.put_line(total);
end;
oracle创建视图:
create or replace view abin1_view
as
select t.* from abin1 t;
oracle创建package:
create or replace package abin_pac is
procedure abinpac;
end;
oracle创建package body:
create or replace package body abin_pac is
procedure abinpac is
total number;
begin
select count(1) into total from abin1;
dbms_output.put_line(total);
end;
end;
测试代码:
begin
abin_pac.abinpac;
end;
