oracle学习总结

1. 创建表

create table  test_ty(
id integer not null primary key,
name varchar2(40) not null,
passwd varchar2(56) not null);

 2. 创建函数

CREATE OR REPLACE FUNCTION MD5
( p_str in varchar2)
RETURN varchar2 IS
BEGIN
RETURN Utl_Raw.Cast_To_Raw(DBMS_OBFUSCATION_TOOLKIT.MD5(input_string => Upper(P_Str)));
END;

 3. 修改表

alter table test_ty  modify column (passwd varchar2(32) not null);

 4. 创建函数

create sequence test_ty_sequence increment by 1 start with 1 nomaxvalue nocycle cache 10;

 5. 创建存储过程

create or replace procedure insert_test_ty(p_name in varchar2, p_passwd in varchar2)
is
begin 
  insert into test_ty(id, name, passwd) values (test_ty_sequence.nextval, p_name, MD5(p_passwd);
end;

 6. 调用存储过程

call insert_test_ty('smith', '841021');
