Update column from a list

This is probably very very simple for any T-SQL experts, but I have only just begun to learn SQL. I have an Excel spreadsheet which is a list of items that I want to change one column for. The spreadsheet has the PrimaryID of the items. It is a subset of all the items. I can create a CSV file from the spreadsheet. I want to read from that CSV file and update the records that are listed in the CSV file. Can someone write me a quick and easy SQL command to do what I need?

Table is ITPRICE, want to set ITP_SCOMM = 1, for all records which match the PrimaryID in products.csv. (Do I need a header row in the csv file?) Here is what I tried: (am I close?)

UPDATE ITPRICE
SET ITP_SCOMM = 1
FROM
OPENROWSET('MICROSOFT.JET.OLEDB.4.0',
'Text;Database=C:\;',
'SELECT * FROM [products.csv]') AS P
where P.PrimaryID=ITPRICE.PrimaryID

UPDATE i
SET i.ITP_SCOMM = 1 
FROM ITPRICE i
JOIN
(SELECT fields...
FROM OPENROWSET('MICROSOFT.JET.OLEDB.4.0', 
'Text;Database=C:\;', 
'SELECT * FROM [products.csv]') AS P
)AS R
ON R.PrimaryID=ITPRICE.PrimaryID

Thanks so much for trying to help me!!!!

Tried this as shown and got errors until I made the following changes. Then it updates every row - does not use the CSV file info at all. What have I done wrong?

(CSV file has one column with header PID)

UPDATE ITPRICE
SET ITP_SCOMM = 1
FROM ITPRICE i
JOIN
(SELECT PID
FROM OPENROWSET('MICROSOFT.JET.OLEDB.4.0',
'Text;Database=C:\;',
'SELECT PID FROM [products.csv]') AS P
)AS R
ON R.PID=ITPRICE.ITP_PrimaryID
