You can bulk insert into a temporary table and then select the columns you desire. Here is an example:
DECLARE @TempTable TABLE
(
Column1 INT,
Column2 VARCHAR(10),
Column2 VARCHAR(10)
)
BULK INSERT @TempTable FROM 'Filepath'
SELECT Column1, Column2
FROM @TempTable
As an alternative, I believe that you can use a format file to bulk insert directly into your desired table.
