Hey Doug, Long time lurker here, but was just reading about these new improvements and the thought about cfqueryparam not being able to be cached to memory. I ran into this exact issue with my query browser and like you went the disk route. But for a while there I toyed with an idea of how to make memory caching work by storing the queryparams seperately and replacing them in the sql when needed. For instance, similar to how the new results structure works in cf 7, take the query you are going to generate and pull out the query params, their cf_sql_ types and values into a seperate array from the query. Then in the sql you are storing, store a ? or some other series of characters that you could use (maybe something like [1] which I dont think would ever be valid sql). Then when you are generating the query, you could replace all of the [1],[2] references with the appropriate cfqueryparam stored in the array.
It could be costly having to do string manipulation especially on a larger sql statement, but I would think that would be offset by getting it out of memory than disk. Just a though, let me know if im not clear and I will clarify. On 10/9/06, Doug Hughes <[EMAIL PROTECTED]> wrote:
Yes, the query is cfincluded from the gateway so it's read from disk each time, or however coldfusion handles that. I had a typo in my last message: " Because the queries use cfqueryparam they couldn't be cached to disk." Should have read: " Because the queries use cfqueryparam they couldn't be cached to memory." And yes, once you've run though an application once (or really, generated a specific query once) it'll never re-generate the query unless you delete it from disk.

The idea being once you've run through the app once, it'll never need to parse queries again, because the content of queries is static (in production).
