Mssql old table to new table different data types and empties

Question

I have a new table I created for a membership application for a local club, anyway there existing software stored info in a DBF file I can import this into mssql as a table that's no trouble I am just stuck on merging the old data into the new table.

This is the old Table Structure (From DBF imported into mssql)

[NUMBER] [int] NULL,
[LASTNAME] [char](30) NULL,
[FIRSTNAME] [char](20) NULL,
[TITLE] [char](5) NULL,
[SALUTATION] [char](25) NULL,
[ADD1] [char](30) NULL,
[ADD2] [char](30) NULL,
[ADD3] [char](30) NULL,
[TOWN] [char](30) NULL,
[COUNTY] [char](30) NULL,
[POSTCODE] [char](8) NULL,
[TELEPHONE] [char](30) NULL,
[TYPE] [char](1) NULL,
[PAID] [char](1) NULL,
[COMMITTEE] [char](30) NULL,
[WARNINGS] [int] NULL,
[MONTHDRAW] [int] NULL,
[WOMANS] [char](1) NULL,
[SENIORCIT] [char](1) NULL,
[DOB] [datetime] NULL,
[AMOUNTCLUB] [decimal](6, 2) NULL,
[DATEPAY] [datetime] NULL,
[AMOUNTBRAN] [decimal](6, 2) NULL,
[AMOUNTDUE] [decimal](6, 2) NULL

This is the new Table:

[MemberID] [nvarchar](10) NOT NULL,
[Title] [nvarchar](10) NOT NULL,
[FirstName] [nvarchar](50) NOT NULL,
[Surname] [nvarchar](50) NOT NULL,
[HouseNumber] [nvarchar](25) NULL,
[Street] [nvarchar](25) NULL,
[City] [nvarchar](25) NULL,
[County] [nvarchar](25) NULL,
[Postcode] [nvarchar](10) NULL,
[TelephoneNumber] [nvarchar](15) NULL,
[MobileNumber] [nvarchar](15) NULL,
[EmailAddress] [nvarchar](50) NULL,
[DOB] [date] NULL,
[Age] [nvarchar](10) NULL,
[SeniorCitizen] [nvarchar](5) NULL,
[Warnings] [nvarchar](50) NULL,
[MembershipCategory] [nvarchar](20) NULL,
[ServiceBranch] [nvarchar](20) NULL,
[Paid] [nvarchar](10) NULL,
[ToPay] [float] NULL,
[DatePaidIn] [date] NULL,
[Entry] [tinyint] NULL,
[FOB] [nvarchar](10) NULL,
[JoinDate] [date] NULL,
[SubscriptionYear] [date] NULL,
[TotalPaid] [float] NULL,

I am writing the insert like;

INSERT INTO [dbo].[MemberDetails] 
([MemberID],[Title],[FirstName],[Surname],[HouseNumber],[Street],[City],[County],[Postcode],[TelephoneNumber],[MobileNumber],[EmailAddress],[DOB],[Age],[SeniorCitizen],[Warnings],[MembershipCategory],[ServiceBranch],[Paid],[ToPay],[DatePaidIn],[Entry],[FOB],[JoinDate],[SubscriptionYear],[TotalPaid])
SELECT [NUMBER], [TITLE], [FIRSTNAME], [LASTNAME], [ADD1], [ADD2], [TOWN], [COUNTY], [POSTCODE], [TELEPHONE]
FROM [dbo].[MEMBERS] 
GO

I got as far as that column then realized "how do I do empty values as no one in the old table had a mobile record?" also do I need to do Select AS "new column name" for the old table values?

Suppose you go from OldTable to NewTable, adding an answer column to the original question column:

insert  NewTable
        (question, answer)
select  question
,       '42' -- Specify a literal or default value
from    OldTable

You can also omit the new column from the insert list:

insert  NewTable
        (question)
select  question
from    OldTable

This will copy the question column and put the default value null in the answer column.

You do not have to use aliases in the select list. It's strictly order based. This would work fine:

insert  NewTable
        (question)
select  question as CeciNEstPasUnePipe
from    OldTable
