RE: The vagaries of QueryNew
Doh! Yes showing code is good and here's the offender...

I have rarely ever used that function but it seems familiar... As if, instead of adding the new column and updating the existing rows, it added the column but added double the rows and updated only the new rows.

I am having a problem with CFGRID where I get Multiple row insert is not supported when a user clicks the insert row button more than once.

Don't forget - Spectra is just CFML. You should be able to find the
function that is doing the conversion.

Re: Converting regular date to a Spectra formatted database date?
I don't think this is a Spectra specific date, but it may be an atomic date (sorrynot up to speed on all the odd formats). So the first thing you need to sort out is the type of date format that number represents. Then it should be easy to find the function you need to take a normal date and produce one of those dates (either already available in CF or perhaps via UDF or other easy bolt-ons). Wowso some Spectra code actually made it into production before it collapsed in on itself under its own weight huh ;-) Cheers On Thu, 2011-03-24 at 10:06 -0400, Gabriel Ortiz wrote: Working with some legacy spectra data and I'm trying to do a sql search based on the spectra date.

Is saving a query in the session passed by reference or by value?

Re: Is saving a query in the session passed by reference or by value?
I'm trying to wrap my head around this, so please excuse me for jumping in. If I understand this correctly, the query result is an object placed in memory when execution is complete, and variables.qry is merely a pointer to that object. When the cfset session.myQry = variables.qry is executed, a second pointer to the query object is created, in the session scope. When page execution completes, the variables.qry pointer disappears (and I assume is garbage collected at some point), but because the session.myQry pointer still exists in the session scope, the query object remains in memory instead of being garbage collected. Once the session times out, assuming there are no other pointers to the query object existing, it would then be garbage collected. Is this a correct understanding, or am I completely off my rocker?

Re: Is saving a query in the session passed by reference or by value?
the easy solution is to create the query in the session scope to begin with cfquery name=session.myquery however storing complex vars such as queries in sessions for every single user can consume a lot of memory. If the contents of the query are not unique to each user, you could just cache one copy in application scope. The other alternative is to cache the entire dataset you need to store on in application scope and use query of query for each user to get their subset of data. If storing the query in the session is a must, you may want to try converting it to JSON or WDDX and see how much memory this uses compared to the query. Don;t forget not to select columns you don't need.

When page execution completes, the variables.qry pointer disappears (and I assume is garbage collected at some point), but because the session.myQry pointer still exists in the session scope, the query object remains in memory instead of being garbage collected. Once the session times out, assuming there are no other pointers to the query object existing, it would then be garbage collected. Is this a correct understanding, or am I completely off my rocker?

But I'm wondering how that works when storing them in the session scope. For example, let's say I have a query that returns a really large result set, and after that query runs I store the query results as a variable in the session scope. cfquery name=variables.qry select* FROMbigTable /cfquery cfset session.myQry = variables.qry Would the above code just create a reference to the result set already in memory, or would it actually create a copy of the results in the session? In a similar scenario, what would happen if I had a CFC object stored in the session, then passed my query results to it to be stored in that CFCs variables scope? cfquery name=variables.qry select* FROMbigTable /cfquery cfset session.myCFC.blah(variables.qry) -- Thanks, Eric Cobb http://www.cfgears.com Help me make a difference this summer. http://bit.ly/i8dJvQ ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:343258 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: SOT - Members only app
if you are simply asking about the security side of things, then the best way is to use .htaccess which will secure EVERYTHING, not use cf files. You should already have this or something equivalent available by default, ask your host.
