• <CFFLUSH>

• <CFLOG>

• Enhancements to <CFFORM> objects

• GetHTTPRequestData


Running “queries of queries”

• CF5 allows you to run queries against recordsets stored in memory from a <CFQUERY> tag• Join the results of two queries together in memory (simulating sql stored procedure temp table functionality)• CF5 supports a minimal subset of the ANSI standard

• Group By• Order By• Aggregate Functions (Count, Sum, Avg, Max, Min)• As• Boolean (Not, Like, IN, Between, AND, OR• DML (Outer Join syntax)


Running a query against a recordset

<CFQUERY NAME=“getemp” datasource=“foo”>

select lastname,firstnamefrom personorder by lastname

</CFQUERY>

<CFQUERY NAME=“getempbyfirstname” dbtype=“query”> select *

from getemporder by firstname

</CFQUERY>


User-Defined Functions using <CFSCRIPT>

• <CFSCRIPT> (introduced in CF 3.x) now gets javascript-like function support

• <CFSCRIPT> functions will perform better than calling CFML custom tags

• UDF’s can be recursive


User Defined Functions using <CFSCRIPT><CFSCRIPT>

function addit(x,y) {

var total=x+y;

return total;

}

</CFSCRIPT>

<CFSET myval = addit(2,2)>

<CFOUTPUT>#myval#</CFOUTPUT>


<CFSAVECONTENT>

• <CFSAVECONTENT> caches the HTML output of all CFML constructs within the tags

• Enables the caching of specified sections of a page for later recall

• Similar to <CFA_GeneratedContentCache> in Allaire Spectra and other tags currently available on the Allaire Tag Gallery

• Operates faster than the tags on the Gallery

• NOTE: All output is suppressed within the tags


<CFSAVECONTENT><CFIF not isDefined("session.mycontent")>

<CFSAVECONTENT variable="session.mycontent">

<CFQUERY NAME="getemp" DATASOURCE="uikitdevsample">

select * from empemployees

</CFQUERY>

<CFOUTPUT QUERY="getemp">

#firstname# #lastname# <BR>

</CFOUTPUT>

</CFSAVECONTENT>

</CFIF>

<CFOUTPUT>#session.mycontent#</CFOUTPUT>


<CFFLUSH>

• Flushes the current ColdFusion output buffer

• Use it to start sending output to the web client before the page has fully completed processing

• After a <CFFLUSH> has executed, the following tags will generate an exception:

• CFCONTENT

• CFCOOKIE

• CFFORM

• CFHEADER

• CFHTMLHEAD

• CFLOCATION


<CFFLUSH>

<CFQUERY NAME="getperson" DATASOURCE="careernotesdev">

select personfname,personlname

from person

</CFQUERY>

<CFFLUSH interval="100">

<CFOUTPUT QUERY="Getperson">

#personfname# #personlname#<BR>

</CFOUTPUT>


<CFLOG>

• Programmatically create a log entry in any of the standard log files (or create your own!)

• Generate application-specific, scheduled task, and custom logs

• Limit logs by size and entries by age

• Utilize the new CFADMIN log viewers to view logs

• Writes out information comma-delimited• Type

• Thread

• Date

• Time

• Application


<CFLOG>

<CFLOG text=“Completed Process Successfully”log=“Application”

Type=“Information”

Thread=“Yes”

Date=“Yes”

Time=“Yes”

Application=“Yes”>


Enhancements to <CFFORM>

• The CFTextInput, CFSLIDER, CFTREE, and CFGRID tags were completely rewritten

• The controls run more consistently in JVM’s

• The <CFFORM> tag now has a preservedata attribute that will autoload information into a control if the page submits to itself.

• Users are prompted to install the Java 1.3 runtime from the web


GetHTTPRequestData

• Makes HTTP Request Headers available for potentially capturing SOAP request data

• Information is returned in a structure


<CFDUMP?>
