Just load the entire file and then delete the variables you don't want.

help dbload
for details on how to use dbload.

Currently, dbload can be used only to load all the tseries from the CSV file. You can, though, then use the times operator * to keep only the database entries you want. For instance
d = dbload('mydata.csv');
d = d * {'x1','x2','x3'};
will load all the series from the CSV file, while the second line will retain only series named x1, x2, x3, and remove all other series.

I will create an option in the dbload function to make the selection.
