Hi,
I have a table as follows:
protein_id | name
___________ ______
P04667 Albumin
P45366 Lactoglobulin
....
etc
I have a perl script that will insert data into this table from a file
containing a list of protein_id and names. However, I only want to insert
proteins where they are not already present in the database. Is there a way to
do this using an SQL command?
Thanks
