How to insert new rows to master table

[keys4worship]

I use Ftp to import a comma delim file.
Problem:

Day 1 file has 5 records. During the course of Day 1 ,users make
changes to a field in the five records.

Day 2 has same 5 records as they were at the beginning of Day 1(without
changes made during Day 1) plus 1 new record.

I need a statement that will only add the 1 new record to the master
table and leave the other 5 fields alone.

I have a composite key that prevents duplicate addition.

My original idea was to have a master table(Day 1) and a daily
table(Day 2) and do some kind of join that would give we only the
records in Day 2 that do not appear in Day 1 using the Composite key.

This has not worked.

Any ideas?

INSERT INTO MasterTable (key_col, col1, col2, ...)
SELECT D.key_col, D.col1, D.col2, ...
FROM DailyTable AS D
LEFT JOIN MasterTable AS M
ON D.key_col = M.key_col
WHERE M.key_col IS NULL
