Background:

I have a text file with over 1.5 Million lines and growing by 1440 lines a day. This is an output file for my weather station. I use the import feature of dbForge to import the data into my MySQL db. I have a batch file that references a dbForge import template to import to my MySQL db every minute.

What I would like is the ability not to exclude the first x number of rows, which is already a feature, but to import the last x number of rows. say for example, in my case, if I wanted to import only the last 30 days I would limit import to the last 43,200 rows. This would dramatically improve the import speed.
