RE: storing query results while paging through
Assuming your query pulls all of the results and you use the startrow and maxrows attributes when outputting, you could just use the cachedwithin attribute of cfquery itself to store the results in memory without all the fuss of session variables. This will also have the benefit of using the same cache if multiple sessions search for the same thing while it's in the cache. -Justin -Original Message- From: George Abraham [mailto:[EMAIL PROTECTED] Sent: Monday, January 23, 2006 10:34 AM To: CF-Talk Subject: storing query results while paging through All, I don't use session variables at all, but this might a good time to use them. I have a search page that takes in a search term, runs a query and then displays the results.

Re: storing query results while paging through
Justin, Suppose the query is named 'getResults' and I have enabled the cachedwithin attribute. Say user1 comes along and searches for 'Portugal'. The query 'getResults' is cached. Then user2 comes along and searches for 'Spain'. This happens while user1 is paging through the resultset for 'Portugal'. Then user3 comes along (while the sessions for user1 and user2 are still on) and searches for 'Argentina'. What happens to the cache for 'getResults' while all this is happening? How does CFMX 7 (which I am on) handle all these interactions for cached queries? Thanks, George On 1/23/06, Justin D.

When you use CACHEDWITHIN/CACHEDAFTER, CF identifies cached queries not just by name, but by connection and by the actual SQL statement. So, each user would generate their own cached query, and CF would only reuse one of them if another request used one of the previously-entered search criteria.

RE: storing query results while paging through
The cache is based on the query name, as well as the actual query going to the SQL server. If the search string is different, then the query would be different, so it would get cached independently of the others. Note that if you are using cfqueryparam in the query, it cannot be cached with cachedwithin. -Justin -Original Message- From: George Abraham [mailto:[EMAIL PROTECTED] Sent: Monday, January 23, 2006 12:13 PM To: CF-Talk Subject: Re: storing query results while paging through Justin, Suppose the query is named 'getResults' and I have enabled the cachedwithin attribute.

By connection he means database connection from the CF server to the DB server. This is not related to a session. Since it is not related to a session, many users can share the *exact* same query.
