Insert to MS-SQL 2008 Database
<cffile action="READBINARY" file="#form.FileContents#" variable="binPDF">
<cfquery name="Uploaded" datasource="#cfbasedatasource#">
INSERT INTO UploadedFiles
(
AccountId,
Filecontent
)
VALUES
(
'#UrlAccountId#',
<cfqueryparam value='#binPDF#' cfsqltype='cf_sql_blob'>
)
</cfquery>
=========================
This is Show from Database to browser:
<cfset binaryData = #cfGetfilecontentquery.Filecontent[1]#>
<cfheader name="Content-Disposition" value="inline; filename=testDocument.pdf">
<cfcontent variable="#binarydata#" type="application/pdf" reset="yes" />
But I can only see in browser "Fail to Load PDF Document"
Your code is correct in principle. Make sure that the settings in the CF admin allow for blob data - otherwise it may be truncated in the DB. It's pretty typical to not allow BLOB data through the driver (by default it is NOT allowed in the DSN settings). If you enable it you should be good.
I'm posting this answer so you can flag it as correct based on the comments (per Leigh's suggestion). :)

OK, so I've spent the last couple of days researching this issue on various websites including this one and I'm still no closer to having an answer. I have seen claims that this was a bug and was fixed on Adobe's end in one of the CF11 patches and I have even seen one answer that claimed that Adobe was emailing the fix directly to individuals - though no information on how to go about getting Adobe to do that was provided on that webpage.
We just updated our intranet to Coldfusion 11 and pages that have a cfgrid using the HTML format and bind data from a cfc no longer show the cfgrid on the page. Other pages that use the Flash format with cfgrid (which apparently can't use the bind attribute with Flash) do work. These HTML cfgrid pages were working properly in Coldfusion 9 before we migrated to 11.
I have simplified the code as much as I can to eliminate other error possibilities - i.e. I've stripped out formatting and am pulling only a couple columns from the database. Here is the code I am currently working on in my dev sandbox:
<cfgrid format="html"
name="userGrid"
bind="cfc:editorFunc.getGridData({cfgridpage},{cfgridpagesize},{cfgridsortcolumn},{cfgridsortdirection})"
pagesize="20">
<cfgridcolumn name="REGION" header="Region">
<cfgridcolumn name="managmentArea" header="Management Area">
</cfgrid>
Here is the code in the cfc (the query does produce results when dumped to the page):
<cffunction name="getGridData" access="remote">
<cfargument name="page">
<cfargument name="pageSize">
<cfargument name="gridsortcolumn">
<cfargument name="gridsortdir">
<cfquery name="records" datasource="webData">
SELECT REGION, managmentArea
FROM areaDesc
ORDER BY Region ASC
</cfquery>
<cfset result = queryConvertForGrid(duplicate(records), arguments.page, arguments.pagesize)>
<cfreturn result>
</cffunction>
Has anyone had any luck getting a cfgrid like this to work in CF11? I could try a JQuery solution like JGrid, however I would prefer to figure out the existing issue with this code if possible.
Any help is much appreciated.
Add this..
<cfif not len(trim(arguments.gridsortcolumn))>
<cfset arguments.gridsortcolumn = "REGION">
<cfset arguments.gridsortdir = "desc">
</cfif>
query....
ORDER BY #arguments.gridsortcolumn# #arguments.gridsortdir#
Well, I have been experiencing same error as discussed here:
Coldfusion 10 File Not Found Error
I am using Coldfusion 11 , developer edition on my Laptop , Windows 8.1 Pro (OS).
People have suggested two approaches over there to overcome this problem:
1) Setting Missing Template in CFAdmin
2) Setup onMissingTemplate function in Application.cfc
I am basically not sure with any of the approaches , however, I would like to go with the first approach. Could anyone tell me how should I set up missing template in CFadmin?
Why do you prefer letting the server handle the missing template? Myself, I like to handle it on a per-application basis. Some applications should never have links leading to non-existing files, others may operate on that as part of its core.
Straight from adobe's docs, you can use (I accidentally pulled this info from cf8 docs, but the link is to current docs and the result is largely the same.
<cffunction name="onMissingTemplate" returnType="boolean">
<cfargument type="string" name="targetPage" required=true/>
...
<cfreturn BooleanValue />
</cffunction>
For a few of my projects, I've written a CMS (Content-Management-System) that stores all the content in the database in fashion.
CMSPages
------------
PID PTitle PFile PContent
1 Home /index.cfm <b>Hey!</b> Welcome to our gollygizmo website.
And then I (my real code actually uses cfincludes rather than directly in the document. You can do it either way, but it was easiest for me to demonstrate with inline code).
<cffunction name="onMissingTemplate" returnType="boolean">
<cfargument type="string" name="targetPage" required=true/>
<cftry>
<cfquery name="FindPage">
select * from CMSPages
where pFile = <cfqueryparam cfsqltype="nvarchar" value="#Arguments.targetPage#">
</cfquery>
<cfif FindPage.recordcount eq 1>
<cfoutput query="FindPage">show page stuffs</cfoutput>
<cfreturn true>
<cfelse>
<!--- Page not found, log some stuff or email stuff
include cgi data so you know where the link came from --->
Hey, this page doesn't exist, sorry about that.
<cfreturn true>
</cfif>
<cfcatch>
<!--- Something went wrong, log/email error info and --->
<cfreturn false>
<!--- We return false here to pass it back to the default error handler, which can be a handler set in cfadmin. --->
</cfcatch>
</cftry>
</cffunction>
In such a scenario, it's probably beneficial to cache queries based on query name, you can do something like
<cfquery name="local.FindPage#hash(arguments.targetpage)#" cachedWithin="...">
...
</cfquery>
<cfset request.FindPage=local["Findpage#hash(arguments.targetpage)#"]>
So that the queries are cached by unique names, even though it's easily accesible in your document by a common name.
However, if you still prefer server-centric missing template handling, a simple search for cold fusion admin missing template will bring you here.
In the ColdFusion Administrator, click on "Settings" to view the "Server Settings" page
Specify the absolute path that ColdFusion will use to find your error handling template
I am severely new to ColdFusion... I have searched for help on this statement and have found a bunch of material, but still don't understand what is going on. All of the parts of this statement make sense, but when I put them all together, it's confusing... the ColdFusion 8: IsDefined("URL.variable) and is not"" thread is the closest, but I still don't understand. This is the 1st statement in the index.cfm file of my application. It's not throwing an error, I just want to understand how it works. Thank you.
I have yet to be able to successfully post code here, so here is a link to a text version of the index.cfm.
Edit:
The code below should be the relevant sections related to URL.openFile
<cfif isdefined("URL.openFile")>
<cfquery name="getFile" datasource="xxxxxxxx">
SELECT filename, filename2, filecontent, filesize
FROM Help_FooterInfo
WHERE Help_id=5 and Section='Registration'
</cfquery>
<cfset sproot=#getDirectoryFromPath(getTemplatePath())#>
<cfset newDest = #sproot#&"temp\">
<cfoutput query="getFile">
<cfheader name="Content-Disposition" value="attachment; filename=#getfile.FileName2#">
<cfcontent type="application/msword" variable="#getfile.filecontent#">
</cfoutput>
</cfif>
...
<cfquery name="getRegistration" datasource="xxxxxxxx">
select * from help_footerinfo where help_id=5
</cfquery>
....
<cfoutput>#getRegistration.Content#</cfoutput><br>
<a href="<cfif #getRegistration.filename2# neq "">index.cfm?openfile=Yes</cfif>" target="_blank">
<u><cfoutput>#getRegistration.FileName#</cfoutput></u>
</a>
The error message I am receiving (see comment below): ORA-00942: table or view does not exist (ColdFusion application)
This:
<cfif IsDefined("URL.variable") and URL.variable is not "" >
means, "If url.variable actually exists and is not an empty string".
A better alternative for isDefined("URL.variable") is StructKeyExists(url,"variable").
Other alternatives for is not "" include len(trim(url.variable)) gt 0, and isNumeric(url.variable).
I am trying to create a spreadsheet (.XLS file) using Adobe ColdFusion - 8.
The code that creates a spreadsheet is:
<cfsetting enablecfoutputonly="Yes">
<cfset date_from = "#URL.date_from#">
<cfset date_to = "#URL.date_to#">
<cfset query_id="#URL.queryID#">
<cfquery name="GetEmps" datasource="cfdocexamples">
<!--- My SQL Queries Goes Here--->
</cfquery>
<cfcontent type="application/msexcel">
<cfheader name="Content-Disposition" value="filename=Employees.xls">
<cfoutput>
<table cols="4">
<cfloop query="getData">
<tr>
<td>#uid#</td>
<td>#week#</td>
<td>#book_count#</td>
</tr>
</cfloop>
</table>
</cfoutput>
Whenever I run the page, an XLS sheet is created, but I cannot find any data. The size of the created XLS file is 0.
Please Note: The Query is correct(Since when I print the output as html, I can see the table without any error/warning).
** After reading comments: UPD**:
I had updated my code and only included important code snippet now.
UPD 2:
Whenever I commented the line <cfsetting enablecfoutputonly="Yes"> , xls file is created with expected data. However, when I opened the generated file, a dialogue appears:
Please note the spreadsheet generated is perfect. Only thing that is bothering me is the above warning.
Also Note: whenever I tried to open the spreadsheet in google-docs as a preview, it says, the file could not be opened due to corrupted format.
However, I am able to open it perfectly in an MS-Excel.
Even changing content type to : <cfcontent type="application/vnd.msexcel"> , I got the same warning.
While I cannot speak exactly how to implement this, I know the developers within my organization worked around it with the Apache POI. It seemed to do the trick for them. It does have to be completed with Java through Coldfusion. Here is an example of it.
I am using Coldfusion 8 and I am trying to serve a file of 15mo with cf_content. The problem is that the download freezes randomly. At the moment, I only tried locally, therefore the network is not the problem. I have tried with smaller files and freezes happen less often. I have no idea of the root of the problem. Here is my coldfusion code:
<cfheader name="Content-Disposition" value="attachment; filename=test.zip">
<cfcontent type="application/zip" file="C:\Test.zip" deletefile="no">
I tried to download the file with Chrome, IE and with a piece of java code to download the file (freeze on the read method after some iteration).
Do you have any idea of how I can easily stream a file using Coldfusion? Maybe it is possible using a Java Custom tags but how to write bytes to page as the custom tag write method of the Response object only allows to write a String?
I did this for a client. I am gathering a number of documents and zipping them for download. Rather than stream them, I save the zip file on the server:
<cfzip action="zip" file="#expandpath('/data/briefcase/')##session.order_id#.zip" source="#expandpath('/data/briefcase/')##session.order_id#" overwrite="yes" storepath="no">
Then I provide the user a link to download the file. That way, if it fails, they can always try again.
I then wrote a scheduled task that runs every day and delete any zip files more than 24 hours old.
<cfdirectory action="list" directory="#expandpath('/data/briefcase/')#" name="filelist" >
<cfquery name="filter_file" dbtype="query" >
SELECT * from filelist WHERE datelastmodified < #dateadd("h", -48, now())# AND type = 'File'
</cfquery>
<cfquery name="filter_dir" dbtype="query" >
SELECT * from filelist WHERE datelastmodified < #dateadd("h", -48, now())# AND type = 'Dir'
</cfquery>
<cfset path = expandpath('/data/briefcase/')>
<cfoutput query="filter_file">
<cfif fileexists('#directory#/#name#')>
<cffile action="delete" file="#directory#/#name#" >
</cfif>
</cfoutput>
<cfoutput query="filter_dir">
<cfif directoryexists('#directory#/#name#')>
<cfdirectory action="delete" directory="#directory#/#name#" recurse="true" >
</cfif>
</cfoutput>
See if helps to prepend your code with:
<cfheader name="Content-Length" value="#GetFileInfo('C:\Test.zip').size#">
That tells the browser how much data to expect.
