আমি দেখতে পাচ্ছি প্রধান অসুবিধাটি হ'ল এটি আপনার বলা আছে:
কোনটি আপনাকে ইউআইয়ের জন্য প্রয়োজনীয় ডেটা সম্পর্কে সর্বাধিক তথ্য দেয়?
এই
CREATE TABLE [dbo].[BusData](
[ID] [int] IDENTITY(1,1) NOT NULL,
[RecordId] [nvarchar](MAX) NULL,
[CompanyName] [nvarchar](MAX) NOT NULL,
[FirstName] [nvarchar](MAX) NOT NULL,
[LastName] [nvarchar](MAX) NOT NULL,
[ADDRESS] [nvarchar](MAX) NOT NULL,
[CITY] [nvarchar](MAX) NOT NULL,
[County] [nvarchar](MAX) NOT NULL,
[STATE] [nvarchar](MAX) NOT NULL,
[ZIP] [nvarchar](MAX) NOT NULL,
[PHONE] [nvarchar](MAX) NOT NULL,
[COUNTRY] [nvarchar](MAX) NOT NULL,
[NPA] [nvarchar](MAX) NULL,
[NXX] [nvarchar](MAX) NULL,
[XXXX] [nvarchar](MAX) NULL,
[CurrentRecord] [nvarchar](MAX) NULL,
[TotalCount] [nvarchar](MAX) NULL,
[Status] [int] NOT NULL,
[ChangeDate] [datetime] NOT NULL
) ON [PRIMARY]
অথবা এটা?
