If you had one big table then Select year, month, day, location, time_wind >From dataTable Where year >= '#minyear#' And year <= '#maxyear#'
If there are multiple tables then you need more then one query. Select year, month, day, location, time_wind >From dataTable2001 Select year, month, day, location, time_wind >From dataTable2002 ect It would be best to have a table such as: Id, year, month, day, location, time_wind And id being the primary key where id auto increments. Having a large table in a database is not issue and is probably a simpler approach. A quick google showed that for SQL server: There is no maximum number. You can keep adding rows until the database runs out of space. As far as other maximums go :- SQL 6.5 SQL 7.0 Database size 1 TB 1,048,516 TB File size 32 GB 32 TB Files per database 32 32768 (http://www.windowsitpro.com/Articles/ArticleID/14356/14356.html?Ad=1) Paul -----Original Message----- From: John Barrett [mailto:[EMAIL PROTECTED] Sent: Wednesday, 19 September 2007 4:12 PM To: CF-Newbie Subject: multi-table DB Hi, I have a huge database of daily records(about 60 years),and I have made a table for each year. I am confused what is the best way to have CF get all the data? for one year I can just do a cfquery of the table, no problem here, but if I want to view lets say 10 years of data, how would I go about this? the db as the form of: year month day location time wind I was thinking I could use "year" as the primary key, but then changing changing the years is what leaves me so confused. I say this as I think that the first db field has to be the primary key? I hope that I wrote this good enough to where you can make sense of this and send some help. I could also show sample code as well. Somebody told me why not just have everything in one table, but then that would be way too big I think.
