How do I bulk insert only a partial record into a MS SQL db with a stored proc.?

Dear experts,

I need to bulk insert 450 student profiles into a MS SQL db. The student profile table contains 48 fields. The school has provided a tab delimited file but only the first 12 fields have data. Mapping the insert for all 48 fields is tedious and is complicated as 1 error can throw the entire insert off.  For a simple test of the bulk insert I created a table and text (tab delimited) file. The db is on a unix system. The code below is the code that worked for inserting 3 fields. How would I modify it to add a record including the other 9 fields...
             [phone_number]  nchar(25),
             [student_id]    int,
             [ethnicity]     nchar(25),
             [gender]        nchar(10),
             [date_of_birth] smalldatetime,
             [grade]         smallint,
             [he_she]        nchar(10),
             [him_her]       nchar(10),
             [his_hers]      nchar(10),  

...without having to map all 48?

Code that works for bulk insert 3 fields, unix system:
ALTER PROCEDURE [dbo].[uspImportStudentInfoNoDuplicates]
      -- Add the parameters for the stored procedure here
--      @p1 int = 0,
--      @p2 int = 0
AS
BEGIN
      -- SET NOCOUNT ON added to prevent extra result sets from
      -- interfering with SELECT statements.
      SET NOCOUNT ON;


CREATE TABLE ImportStudentTempTable
(last_name varchar(50),
first_name varchar(50),
middle_name varchar(50)
)

DECLARE @bulk_cmd varchar(1000)
SET @bulk_cmd = 'BULK INSERT ImportStudentTempTable
FROM ''\\*********Location of txt file'
WITH (ROWTERMINATOR = '''+CHAR(10)+''')'
EXEC(@bulk_cmd)


-- Insert the new student records
INSERT INTO ImportDataTest
   SELECT last_name, first_name, middle_name
   FROM ImportStudentTempTable


DROP TABLE ImportStudentTempTable

END

Your solution worked perfectly and I'll give you the points. I'm still learning about stored procedures having only written a few. Can you tell me why you used the "#" in front of the temp table name? Thanks. Bob

Tables created with a name of # are temporary and live only while the session is active.
If they are created in a SP, you don't even need to drop them - they automatically disappear.
Other options are ## (these stay until the server is rebooted and live in tempdb) and @ - these are variables that work like a table.
It is not good practice to create a [real] table within an SP, even if you drop it, just for the sake of some temporary work.
