Copy and paste?
If you control the .cfm i.e. can edit it, you need need to use startrow and maxrows in your <cfquery> to utilise pagination and control how many records are displayed at once e.g. <cfoutput query="getData" startrow="10" maxrows="20">. If you want to display all records at once, remove the startrow and maxrows from the <cfquery>.
If you don't have access to the .cfm template you will have to ask the person who authored it to see if it supports any parameters to allow it to display all records (or try and guess them :).
I think your best hope is to ask the author of the CFM whether they provide any web service that can get you that data when you call it. like.
There's a chance they may be regulating performance on the resultset, and don't want to return that many records at a time, pagination or not.
Thank you all for your replies. I have tried modifying startrows and maxrows.. startrows works exactly as one would expect it to, however whenever maxrows is set above 20, it sets itself to 20 (even though it will display maxrows=50, it will only give you 20 results).
I believe your responses confirm my initial thought that they are purposefully limiting the results to 20/page and my options are to copy paste 20 at a time or find a way to custom scrape the data..
