create table Company_Info ( Company_ID NVARCHAR2(50) not null, Area_ID NVARCHAR2(50), Mem_ID NVARCHAR2(50), Level_Id NVARCHAR2(50), Name NVARCHAR2(50) not null, Capital NVARCHAR2(50), Unit_Property NUMBER(2) not null, Economics_type NUMBER(2) not null, Man_Scale NUMBER(10,0), License_Code NVARCHAR2(50), License_Img NVARCHAR2(50), Intro NVARCHAR2(3000), Company_Img NVARCHAR2(200), Address NVARCHAR2(200), Postal_Code NVARCHAR2(50), Tel NVARCHAR2(50), Fax NVARCHAR2(50), Mobile NVARCHAR2(50) not null, Email NVARCHAR2(50) not null, Contactor_sex NUMBER(2), Contactor NVARCHAR2(50), Web_Site NVARCHAR2(200), View_Count NUMBER(20,0), Create_Date DATE not null, Update_Date DATE not null, Status NUMBER(2), Company_Type NUMBER(2), Remain_Point NUMBER(6,0), Cmp_Level NVARCHAR2(50), isAdv NUMBER(2), Expri_Date DATE, Display_index NUMBER(6,0), constraint PK_COMPANY_INFO primary key (Company_ID) );

alter table Company_Info add( Remain_Point NUMBER(6,0), Cmp_Level NVARCHAR2(50), isAdv NUMBER(2), Expri_Date DATE, Display_index NUMBER(6,0) ) 这样就加快了我们的开发效率.
