ColdFusion caching SQL Server credentials?

I have been using ColdFusion's storedProc() service for a while with no issue. However, I have run into a scenario where I have a local stored procedure executing a remote stored procedure. When I attempt this via ColdFusion, I receive a very cryptic error:
The DBMS has returned the command code 224...
The following is the code I am using:
variables.storedProcService = new storedProc();
variables.storedProcService.clear();
variables.storedProcService.setAttributes(datasource="DATASOURCE", procedure="STOREDPROCNAME");
variables.storedProcService.addParam(cfsqltype="CF_SQL_INTEGER", type="in", value=0);
variables.storedProcService.execute();
However, executing the exact same procedures from SQL Server Management Studio results in no issues.
Then, when I use the following code:
variables.storedProcService = new storedProc();
variables.storedProcService.clear();
variables.storedProcService.setAttributes(datasource="DATASOURCE", procedure="STOREDPROCNAME", username="USERNAME", password="PASSWORD");
variables.storedProcService.addParam(cfsqltype="CF_SQL_INTEGER", type="in", value=0);
variables.storedProcService.execute();
The execution runs without issue. My question is this, does ColdFusion cache SQL Server/Datasource credentials? Why does it [seem to] not use the credentials I provided in Jrun?

The execution runs without issue.
I can actually just include the password attribute and the stored procedure runs just fine.

Using SQL Server credentials with Secure Store Target Application for Data Connection in Dashboard Designer

[Using SharePoint 2013 Enterprise SP1]
I would like to use SQL Server credentials in a Secure Store Target Application, and
this page makes it look like it's possible but when I attempt to use the new Target Application ID as authentication for a Data Connection in Dashboard Designer, I get a generic "Unable to access data source" with no error logged in SQL Server
logs.
I am able to use a Target Application with AD credentials to access the SQL db without a problem. Suggestions?

Hi,
1. Make sure that the credential is set to
Secure Store Target Application. Navigate to the Central Administration. Click on the
Application Management. Click on the Manage Service Applications. Click on the
Secure Store Service Application. Select the application ID and from the ECB menu click on the
Set Credentials. Enter the Credential Owner, Windows User Name and the
Windows Password.
2. Make sure that in the Dashboard Designer “Use a stored account” is selected in the “Authentication” and the proper application ID is mentioned.
Please refer to the link below for more information:

Coldfusion - Microsoft SQL Server Traffic Encryption

Hi,
have someone tried/managed to encrypt traffic from coldfusion to SQL Server?
Please share if you don't mind
Thanks

I've not used the SSL features of JDBC but you might start in the documentation.
With bundled CF drivers
http://help.adobe.com/en_US/ColdFusion/9.0/Admin/WS70f0d54f063b9b08238ab6dc122b1a20785-800 0.html
If you are using the Microsoft JDBC driver, not the one bundled with CF.
http://msdn.microsoft.com/en-us/library/bb879935%28SQL.90%29.aspx
You *may* need to import your SSL certificate so that it will be recognized

Coldfusion and sql server reports

hi all,
we wish to have a reporting tool that goes well with coldfusion. we wish to use sql server reporting with coldfusion. can anyone provide some examples for this. i have seen integration only for crystal reports and report builder. does it support sql server reporting too. please help......

If I had ever used SQL Server reporting I would have said something...
But you are embarking on an unusual task and unusual tasks are not usually done be lots of people.
So how does SQL server reporting work? What does it produce? How do you want to tie into it? What do you want to happen?
With all the ways one can tie into other services through ColdFusion and its underlining Java, I suspect there might well be some way to do something. Wether that something is good enough and|or simple enough to be worth the effort I can not say and will require a good amount of knowlege on how SQL server reporting actually works.

Connect coldfusion with sql server

HI everybody
I need to know if i can use sql server as a database and coldfusion as the webpage interface builder???? Can these 2 program work together (be connected to each-other)?? if yes can anybody explain how it can be done or any link or something???????????
thnx in advanced
aldo

In addition to Ken's suggestion, you might want to look at how datasources work: http://livedocs.adobe.com/coldfusion/8/htmldocs/datasources_ADV_MJS_01.html.
But, to be honest, this is such a fundamental question to be asking, I think you pretty much need to get hold of the CFWACK and read that: http://www.amazon.co.uk/Adobe-ColdFusion-Web-Application-Construction/dp/032151548X.
Or take a Fast Track to ColdFusion course or something.

SQL Server 2008 self-signed certificate is 1024bit or 2048bit?

When there is no user defined certificate available, SQL Server will generate a self-signed certificate when service starts, We have a tool scans and finds that in SQL 2005 the self-signed certificate is 1024bit, does someone know the default self-signed
certificate is still 1024bit or is it 2048bit in SQL 2008? Thanks a lot!!!

I will begin my answer by making an emphasis that the best way to protect your data in-transit is using a 2048 bit certificate signed by a trusted certificate authority (CA) instead of relying on the self-signed certificate created by SQL Server.
Please remember that the self-signed certificate created by SQL Server usage for data in-transit protection was designed as a mitigation against passive traffic sniffers that could potentially obtain SQL Server credentials being transmitted
in cleartext, but nothing more. Think of it as a mitigation against a casual adversary.
The self-signed certificate usage was not intended to replace real data in-transit protection using a certificate signed by a trusted CA and encrypting the whole communication channel. Remember, if it is self-signed, it is trivial to spoof.
After making this clarification, the self-signed certificate generated by SQL Server uses a 1024 bit key, but that size may be subject to change in future versions of the product. Once again, I would like to strongly discourage relying on the self-signed
certificate created by SQL Server for data in transit transmission.
BTW. Azure SQL Database uses a 2048 certificate issued by a valid certificate authority.
I hope this information helps,

MS SQL Server 2000 Problem to Connect

Hi There
I have a problem with MS SQL Server 2000 with Service Pack 3 and JDBC from Microsoft
My tools are:
- Windows 2003 Server Standart Edition
- MS SQLServer 2000 with ServicePack 3
- JDBC from Microsoft with ServicePack 3
I want to connect in the database using JDBC.
At first time, I follow the example to chance the authentication of SQL
Server
http://www.banmanpro.com/support/sql2k.asp
Now, when I will try out to connect in the SQL Server, I receive this error
message
java.sql.SQLException: [Micro$oft][SQLServer 2000 Driver for
JDBC][SQLServer]Login failed for user 'Administrador'.
I'm trying to connect in SQL Server using my Windows Account, in other
words, I'm using the ADMIN account of Windows and which was registered in
the SQL Server.
In then DriverManager.getConnection line from Java, the Username and
Password is same the operation system, but I receive the error below.
Maybe Can you help me please?

You can't log in using Windows credentials using the MS driver (yes, I know that sounds kind of funny). Use jTDS for that, if you really need it (or if you encounter any other problems with the MS driver). Otherwise log in using SQL Server credentials (try with user sa and blank password if not sure).

CF Hash and SQL Server

Hi,
Basically, I receive a hash of a pk and would like to compare that hash value a pk in SQL Server. There is no stored hash value in that table. So I have to use CF function Compare to compare while looping the whole table. As a result, it's slow down. Is there any functions in SQL server or something that I can get a quicker comparison result?
Here is basically the loop of the table and comparing.
<cfquery name="name">
     SELECT id
     FROM tbl
</cfquery>
<cfloop query="name">
     <cfset hashID = HASH(name.id,"SHA")>
     <cfif COMPARE(url.id,hashID) EQ 0>
          [do something]
     </cfif>
</cfloop>

Not sure which version of SQL Server you are using, but take a look at the HashBytes function. You could then do:
<cfquery name="name">
     SELECT id
     FROM tbl
     WHERE HashBytes('SHA', id) = <cfqueryparam value="url.id" cfsqltype="CF_SQL_VARCHAR">
</cfquery>
<cfif name.RecordCount>
          [do something]
</cfif>
I'm not sure if "CF_SQL_VARCHAR" is the right cfsqltype, or if it needs to be "CF_SQL_BLOB" (I think hashes are still essentially text, but SQL Server returns a VARBINARY from HashBytes).
EDIT: Make sure that ColdFusion and SQL Server are producing the same results, as they use different hashing libraries. Also, if you are hashing the table id in the URL for security, SHA is a pretty weak hashing algorithm. If you are using SQL Server 2012 or above, you should consider bumping that up to at least SHA-256 (SHA2-256 on the SQL Server side).

Data Compression in ColdFusion 9 for SQL Server 2008

Hi,
I need to store fairly large blocks of HTML text in SQL Server (I won't go into why, unless necessary).
Unfortunately even after stripping out the white space, the text string gets so long that the INSERT/UPDATE query times out.
I'm looking for a way to compress that text on the fly and send over just the compressed string. Then uncompress it when it's retrieved from DB.
The only way I can think of doing it is using CFZIP to create a temporary zip file, then read it in and send that binary string to SQL Server. But I don't know if that'll speed things up any, cause of all the file operations. Ideally I would just do it in memory.
I also looked into GZIP for ColdFusion, but I don't think there is much difference.
Any suggestions?

I don't really want to go into too many details as to why, but in this particular scenario just caching the page doesn't work.
It's used by TV talent to view scores, and has to be almost instant. The scores are coming in from 100 different sources constantly, so if I cache, then the first user who gets to that page has to wait too long for it to load, and I have to keep clearing the cache like every 5 sec. Plus it's on a clustered server, so what I'm doing is I'm doing all the heavy lifting in a separate process that might even run on a different server, and then simply getting the generated HTML from SQL.
When a score comes in it triggers an EventGateway that runs a process to generate all different variations of screens for TV talent in the background.
Then when TV talent looks at any screen in loads instanly cause there are no calculations to be done, and the data is only delayed by how long the process takes. The actuall process is about 10 sec, but it's getting slowed down a lot because the query that sends the HTML over to SQL Server to store, is HUGE.
If I can compress that HTML and store the compressed text, then when I do the SELECT from SQL uncompress it and send it back to the users, that would work just fine.
But I can't figure out how to compress text in ColdFusion. I'm trying to do GZIP but it's not working.
Please let me know if you know how to compress a long string in ColdFusion using either GZIP or any other method.
Thanks.

ColdFusion caching WSDL credentials

We are running ColdFusion 9 (version 9.0.1.274733) on Windows 2003 with IIS 6. The server is shared across a few different groups within our organization each with more than one active development project currently underway. 3 of the projects are attempting to consume a .Net webservice hosted on another server. The webservice is using basic authentication to identifiy who is accessing the service. Our problem is that when ColdFusion accesses the service the first time it caches the WSDL proxy/stubs along with the username and password. This presents a problem when the next application attempts to access the service. The second attempt can access the service but since ColdFusion is using the credentials ofthe first application the second application gets permission problems from the application behind the service. Example is application A hits the service with username A this is followed by application B with username B but IIS sees username A, application C does the same thing, IIS sees the access attempt with username A. If we clear the WSDL from the admin or use the refreshWSDL attribute it works one time, with subsequent access attempts using the first set of credentials. Forcing each application to always use the refreshWSDL attribute kind of defeats the purpose of caching.
So my question is this:
Is there any way to get ColdFusion to NOT cache the username/password information when it creates the stubs?

Have you tried creating multiple named instances of the webservice via the cf administrator? I haven't tried it but it looks like you should be able to assign a different username/password to each instance. Then in your code just instantiate it by the name rather than the wsdl url, eg.
<cfset svc = createobject("webservice", "mywebsvc_appA") />

SQL Server 2005 and ColdFusion 7

Hi all,
I am using SQL Server 2005 and ColdFusion 7 (standalone) on
XP 64 Bit. I was using the exact setup a couple of weeks ago, but
had to reinstall my O/S due to hardware problems so am back to the
beginning. I remember having a nightmare setting datasources up in
the past, but did manage to find a solution.
I have tried the following:
SQL has TCP/IP Enabled
SQL is set to Mixed Authentication
SQL has a login set to the same as my Windows Username and
password
My database has a user (dbo) by the same name as the login
set in SQL
When I add a datasource in the administrator I enter the
windows username and password (I have tried without either as
well), the server name as localhost and the port as the default
1433.
I always get the following error:
Connection verification failed for data source: DATABASENAME
java.sql.SQLException: [Macromedia][SQLServer JDBC
Driver]Error establishing socket. Connection refused: connect
The root cause was that: java.sql.SQLException:
[Macromedia][SQLServer JDBC Driver]Error establishing socket.
Connection refused: connect
Can someone offer any advice? This is driving me proper nuts.
TIA,
Paul

when i did it, i had to update my jdbc driver
