Mysql subquery in concat

Question

I have the following query and file and works fine.

Is it possible to do a subquery for product_id field (SELECT id FROM products where name = 'car') and how can I achieve that?

File:

postcode;huisnummer;toevoeging;product;datum
1775 BB;4;;CAR;02-01-2018

Query:

LOAD DATA LOCAL INFILE '$path' 
INTO TABLE `temp_loc` 
FIELDS TERMINATED BY ';' 
OPTIONALLY ENCLOSED BY '"' 
IGNORE 1 LINES 
(@postcode,@huisnummer,@toevoeging,product,datum)
SET adres = CONCAT(REPLACE(@postcode, ' ', ''),'', @huisnummer,'$',@toevoeging);

Database columns:

merged_adres , product_id, datum
