[Qgis-user] Selecting Records Using an external Text File

[Grant Boxer]

I have a located file with 20k+ records containing photo file names, 
locations and other data. I have another list of 500+ containing photo 
file names only (one field/column) that I would like to use to extract 
the data from the 20+k file (e.g. location and other info) by using the 
photo file name. Is there an expression to compare a value in a field in 
the small text file and select that record in the larger file, i.e. 
select by using the small text file? Any suggestions? Hope this makes sense.
