There is an article in this month's CF Developers Journal about using a
custom tag called 'querysim' to mimic database calls. The article
discusses a number of different uses for it, including using it to parse
through a web server log file (space delimited usually) as if it were a
database recor
we have tried this and are using it, somewhat different in how things go,
but you can set up a datasource to a folder, and then your queries are
something like
select * from somefile.csv
and if there's a header line in the csv, you will get a nice normal query to
work with after that point. work
I would recommend looking at either a java or COM component that is specifically
developed to give you bite sized portions. VB/Com certainly has sequential file
access, which doesn't require you to have 1 MB of RAM for every 1 MB of file size. It
would just allow you to walk through the file

that)
name="grabTextFile"
delimiter=",">
Then you can output it just like a cfquery like so:
#grabTextFile.columnName#

what's the best way to read a very large tab delimeted text file?
does cf.. read the whole file into one variable... how does this get
effected if you're reading a large file?
