So did I get it right? You have both shown tables in you DB and you have a third table in a text file containing an idCars combined with an idSize, so something like this: 

idCars   idSize
------   ------
1        3
1        2
2        1

And you want to get: 

Car          Size
----------   ----------
MiniCooper   sedan
MiniCooper   compact
Civic        subcompact

[download]

I'd create a new table CarSize with the content of your text.

The query (your vlookup) would then be something like this: 

select Car, Size
from CarSize
join Cars
using(idCars)
join Size
using(idSize)

Note: Untested SQL Code I'd write for Oracle. The join-syntax might vary on mySQL.

s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e
