Is the file in a web-accessible location? If so, a quick way is to use CFHTTP to read the CSV directly into a ColdFusion query object. Then you can use that query object to populate your temp table. See Dave Fergusons's blog entry on this: http://blog.dkferguson.com/index.cfm/2011/9/28/CSV-File-Reading-using- cfhttp.
Otherwise, open the file using CFFILE and loop throught the contents (exiting after the first row if necessary).
