    uuid为主键,插入时自动更新

    -- Create table  
    create table TECHNOLOGYCOMPANY  
    (  
      ID              VARCHAR2(32) default SYS_GUID() not null,  
      FLOWID          VARCHAR2(50),  
      CONPANYID       NUMBER,  
      ISCOMMUNICATION VARCHAR2(10)  
    )  
    tablespace USERS  
      pctfree 10  
      initrans 1  
      maxtrans 255  
      storage  
      (  
        initial 64K  
        minextents 1  
        maxextents unlimited  
      );  
    -- Add comments to the table   
    comment on table TECHNOLOGYCOMPANY  
      is '技术交流的交流公司';  
    -- Add comments to the columns   
    comment on column TECHNOLOGYCOMPANY.FLOWID  
      is '申请编号';  
    comment on column TECHNOLOGYCOMPANY.CONPANYID  
      is '竞争对手ID';  
    comment on column TECHNOLOGYCOMPANY.ISCOMMUNICATION  
      is '是否交流';  
    -- Create/Recreate primary, unique and foreign key constraints   
    alter table TECHNOLOGYCOMPANY  
      add constraint SYS_TECHNOLOGYCOMPANY primary key (ID)  
      using index   
      tablespace USERS  
      pctfree 10  
      initrans 2  
      maxtrans 255  
      storage  
      (  
        initial 64K  
        minextents 1  
        maxextents unlimited  
      );  

    后续增加默认主键值:

    alter table 表名 modify 字段名 default 默认值;
