You meant that the error occurs on client Mac users of the same application,
not of installations of your application on Mac CF servers, right ?
Then, since the CF language doesn't know nor it cares for the type of
browser,
the error may only be in the javascript used by CFINPUT.
I
May be I don't catch it, but this will work perfectly in CF:
cfset variables.blah = queryname.columname1
queryname.columname2
queryname.columname3
You need no delimiter to tell CF it s only one statement.
value=#Caller.getItem[attributes.type 'EasyFrame']#
Yes,... except that getItem is a query in the calling template,
So maybe value=#Caller.getItem[attributes.type
'EasyFrame'][Caller.getItem.currentRow]#
Not sure if it is more efficient, but certainly not as easy to read.
Personally I think that the anti-evaluate slant is a bit of orthodoxy
that
was picked up on years ago (when it was much more computationally
expensive) and enforced as such by members of the CF community.
Right, and it is not proper to the CF community, I remember having the
same discussion
I read that in CF8 evaluate() should no longer be necessary.
This is wrong. What is true is Should not be used if not necessary
Which by the way is your case here.
But there are more complex issues where it can't be avoided.
Dave gave you the answer.
Why Should not be used if not necessary?
Because, if it is not necessary, hen there is an alternative using []
and it is more effiecient,
although the difference may be a couple of miliseconds.
What would be an example where it's necessary?
For instance, I have this in a custom tag:
document.registerForm.submit is not a function
Apparently, getElementById() has returned an object which is not a form,
thus which has no submit function..
Make sure no other object has an id=registerForm.

but you can use string
manipulation functions in the ORDER BY clause to sort your data.
That would prevent the query from using an index, and it may have some
impact on performance.
An alternative would be to apply these functions once for all on the

It gets a connection
from the pool, queries the DB, retrieves all the data and finally

I don't think this is unexpected behaviour
It is not only unexpected, it is completely retarded.
All ODBC/JDBC functions are designed so the database can be connected,
then the SQL statement be compiled, then data retrieved row by row, as
needed. Even dBase, Clipper, Foxpro worked this way.
There are a number of reasons why running the select directly in
Access may
appear much faster.
1) You are probably running it locally so there is no costly transfer of
data between servers.
I'm running the CF app locally also, so the difference does not come
from connexion time.

The output of recordCount was there only for illustration purpose.
More specifically, what are you going to do with 300,000 ntext fields

Indeed, while the initial query may take longer, it is perhaps better
performing than hitting the db on each iteration within the request.
Thoughts?
Perfectly right for small result sets.
But as soon as the virtual memory must be used, each record will
generate some read-write-reread action,
did you try experimenting with BLOCKFACTOR attribute of cfquery?
i am just curious, since you already are retrieving such a large
dataset, if using blockfactor makes any difference at all on processing
time...
The blockfactor is supposed to be one by default, but I tried it anyway,
and no, it
blockFactor is only relevant on the Oracle drivers
CF 5 doc says This parameter applies to ORACLE native database drivers
and to ODBC drivers
This is ambiguous, If it applies only to Oracle, it should be stated:
This parameter applies to ORACLE native database drivers and to ORACLE
ODBC
(if CF were able to determine it was a select in the first place)
Well, it must be able somehow to determine the query returns data,
otherwise, how would it create a structure from any result set?
~|
Adobe® ColdFusion® 8
Regardless, CF wouldn't know if the cfquery was going to return a result
set until after it had sent the commands to the database for execution
and waited for the results to come back, and that would sort of defeat
the purpose, wouldn't it?
No, because the driver does not return the result set,
Hi,
I've always thought that all what CFQUERY was doing was to create some
connection to the database, and then the actual content of all records
would be read as needed during some loop on the result set.

If the image is produced from
Any sugestions
Yes, store only the image characteristics like file name, size, title,

Hi,
In CFMX, in mail settings, there is an option to get messages sent
encoded in UTF-8, ISO-8859-1, etc...
IN CF5, there is no such option.
However, from my development desktop, I have a template that sends me a

ie: Subject:

Yes, but this is just to specify the charset of the body of the message,
