Re: st: Modify large data base without opening it
*Some* program has to open the file in order to change it, but that
program doesn't have to be Stata. Nevertheless, if it's taking a long
time in Stata, it's going to take a long time in whatever program you
choose. I suggest switching temporarily to a computer with more RAM,
dropping the variables you don't want, compressing the whole thing, and
then moving back to your regular computer.
You have other options, like opening it in Excel 2007, using SAS or
SPSS, or writing a script in perl, awk, python, or something other
language, but it's very unlikely to be worth the extra effort.

I'm working with a very large data base (1000m, 2000 vars) and my PC
is taking too long to open it. I would like to know if there is a way
or a specific command to drop some variables without actually opening
the data base.
Thanks in advance,
