I'm newbie in ColdFusion.
I have a running ColdFusion website I'd like to update. I've copy the database to make some test, in the ColdFusion manager I have created a new datasource with the copied database. But now how can I tell my website that it need to use the copied database?
Thanks
Look in your code and find any cfquery tags and make sure they are using the new dsn in the datasource attribute. Depending on how the code is written, there may be a global variable that holds the dsn and you can just change it there.
Now that you have a test database, you probably want to use conditional logic to determine which one to use. Here is an example from one of my files.
<cfscript>
if (cgi.path_info contains "dwtest") {
dsn = "AntibioticsTest";
} else {
dsn = "Antibiotics";
}
</cfscript>
<cfquery name="GetLastInsertDates" datasource="#dsn#">
sql not relevent
</cfquery>
As mentioned in jhinkley's answer, this variable might be a global variable in which case it's most likely found in Application.cfc.

I am testing the azure-devops-migration-tools and have create a project using https://azuredevopsdemogenerator.azurewebsites.net/ (Parts Unlimited). I have generated the configuration.json and changed the Source and Target so I can test a migration, but I'm getting errors while migrating Work Items.
[15:14:41 ERR] Error running query
Microsoft.TeamFoundation.WorkItemTracking.Client.ValidationException: TF51005: The query references a field that does not exist. The error is caused by «ReflectedWorkItemId».
I've tried different options on the "ReflectedWorkItemIDFieldName" field, Scrum, Basic, Agile, Custom, empty but am still unable to migrate the work items.
How can I get the value to put on this field for the specific project?
Thanks,
Bruno
Quick Solution: Most ADO instances use the prefix 'custom' for new fields. Try "Custom.ReflectedWorkItemId" in your configuration.json to see if that resolves the problem.
More details: It's hard to tell without an actual configuration.JSON file to review. One possible problem is that you need to use the actual and full internal 'Name' of the ReflectedWorkItemID field. This doesn't show in ADO, or the Process Template when created. The recommendation is that you create a query referencing your custom field, and export the WIQL file (query file). Once you export the WIQL file, you can then open the file and see the full syntax of the custom field.
Exporting Queries: If you don't know how to do this, it can be done with VisualStudio. If you don't know how to do that, you can install this extension. It's a handy WIQL import/Export and editor. Install, and your ADO Queries with have an Edit in WIQL Editor option. Create a query that exposes your 'ReflectedWorkItemID' as a column, then edit that query in the WIQL editor and see the full names of the Reflected Work Items ID Feild. https://marketplace.visualstudio.com/items?itemName=ottostreifel.wiql-editor
SELECT
[System.Id],
[System.WorkItemType],
[System.Title],
[System.AssignedTo],
[System.ChangedBy],
[Custom.ReflectedWorkItemId]
FROM workitems
WHERE ...
I found a possible solution. I have created a custom process, change the process from the projects to this new one and add a new field. This is the field I'm using on the configuration.json and now I'm able to migrate work items
To make the migration in the "ReflectedWorkItemIDFieldName" you must do:
"Organization Settings" -> Process -> Select the process where you project are (Basic, Scrum, Agil, or CMMI).
then click on the 3 dots and create a new Inherited process.
Then with the inherited process, you are able to create a new field for each work item type. The name that you type (could be "IronMan") that name will be in your configuration file.
I am using APEX 5.1.4
Know this is probably one of those very easy answers - just not sure what script is used in a Page Process to call a DB package. Know I need to pass the parameters and call the specific part of the package - just not sure what that page process script should be.
Need to pass in the values from page 3 - :P3_USER_ID (which is the user's email address) and the :P3_PASSWORD. The DB package is called PSPRT_AUTH_PKG and the part of the package is CREATE_ACCOUNT. Thanks!!
Think I found the answer...
use this in the page processing as PL/SQL code...
psprt_auth_pkg.create_account(:P3_USERNAME, :P3_PASSWORD);
Something like (you'll need to correct my made-up parameter names):
PSPRT_AUTH_PKG.CREATE_ACCOUNT
( p_user_id => :P3_USER_ID
, p_password => :P3_PASSWORD
);
I have a table in a database that contains all kind of attachments, images, pdf, excel, and other formats. creating an application is not an option, so I googled other options and I found this related question that mentioned LINQPad I downloaded it but I still do not know how exactly it works. Anyone please explain that to me? I can query the attachments using sql query but not sure how to dump them and preview them via the mentioned tools.
Following on from Dan's answer, once you have the data context set up you can dump the images from the database. I use this snippet for checking an image I've written to the database, you should be able to edit as required to match your scenario:-
var ii = ItemImages.Where (v => v.Id == 10).FirstOrDefault();
using (var ms = new MemoryStream(ii.Image.ToArray()))
{
System.Drawing.Image.FromStream(ms).Dump();
}
Use the Util.Image built in utility for images.
Ex:
var personPictures = PictureTable.Take(1);
Util.Image(personPictures.First().Picture).Dump();
Util.Image takes a byte array.
Depending on your database of your choice, most likely you'll need a data context driver

Once you establish a connection you can start writing queries against the data
I have a php script (ini.php), that open in an iframe inside of "main.php":
<iframe src='ini.php' style='width:650px;' frameborder='0' id="IDMain" allowtransparency="YES" scrolling="NO"></iframe>
The SQL does not retrieve the data in "ini.php".
But if I incorporate the code of "ini.php" in "main.php", without using an iframe, the query retrieves all the information.
I must have an iframe in order to change all the different scripts in the same iframe.
Any help here?
Thanks
In addition more information:
The main.php is in session after logged. Previously I had the whole frame repeated in each script, and everything was ok.main.php, ini.php, and so on. Each script with header, left, right, main and footer. To make it faster and easier I decide to make the main script called main.php, that with an included script called config.inc.php that has several functions, also connects to data base, to retrieve some data to the header, left , right and footer sides of the main area (iframe) where the others different scripts, just to opens inside of a iframe, maintaining the information around. Each script, (like ini.php), that runs in the iframe also include the config.inc.php file, to connect as well to database. But does not retrieve any information
The connection to database in config script is:
<$connect=mysql_connect ("localhost","database","password") or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ("database", $connect) or die ("'I cannot connect to the database "); >
The query in ini,php (and others) is:
`
if ($id) {
$id_session=$_SESSION['id_session'];
$namesession=$_SESSION['name_session'];
$sql="select * from data where id='$id_sessino' limit 1 ";
$result=mysql_db_query("database",$sql);
$regist=mysql_fetch_array($result);
$id=$regist["id"];
$id_session=$regist["id"];
$namesession=$regist["name_session"];
$country=$regist["country"];
And soo on…
}
`
I hope with is information it makes it clear what do I mean. Thank you
Check PHP help for mysql_db_query. Since you are not giving it any open db link, it tries to do some default magic, which likely fails, because, as I mentioned in the comment, the two scripts (in parent window and inside the iframe) are run separately and have no idea about each other *unless you are doing some synchronizing, that isn't shown in the code snippets. That means that the iframe script doesn't know anything about the connection you've opened in the parent page, and fails. Check your logs, you should see some E_WARNING complaints (if you are logging this level).
Also, as the documentation says, you might be better off with MySQLi or PDO_MySQL extensions. But the principle will remain the same - the script in questoin has to have an open connection to the database (and I'm not sure whether you can easily and safely transfer an open from one script to the other one, so you'll likely have to do it all in the iframe script).
Try two things, first I would change the MySQL_fetch_array part to
While($regist = mysql_fetch_array($result))
{
//Code goes here
}
Secondly try referring to the array vales as numbers rather than names, so regist['id'] would become regist[0]. They will be in the order the are in the database.
Also since you select your database when creating connection why not just use mysql_query("QUERY HERE"); Rather than mysql_db_query
How do I send two users coming from different company domains to different SQL databases to retrieve/store data? I use Application variables to store the connection strings and the Request.ServerVariables("LOGON_USER") variable is an effective way to get the domain name. Is the GLOBAL.AsA file to be modified? The table names are exactly the same in both databases, so I think changing the connection strings based on the user domain should do the trick.
User A with domain ABC --> Application("ConnecttoDB") send to database A
User B with domain XYZ --> Application("ConnecttoDB") send to database B
I have roughly 900+ classic ASP pages so I would really hate to add a bunch of IF-THEN's to choose the correct database in each page. All ideas are greatly appreciated!
UPDATE: To make things simple I'm envisioning one single Application variable (i.e.: ConnecttoDB) However, wouldn't its value be constantly changing every time a different user gets access and altering page results?
You can't use an Application variable since that's shared across all users. This would be a race condition. Instead you'll need to use the Session object to store the connection and then use that whenever you need to connect to the DB.
myDB=Server.CreateObject("ADODB.Connection")
StrConn = Session("ConnecttoDB")
myDB.Open StrConn
Here's one way of doing it:
I'm guessing that your classes for your web page codebehind files inheit the Page class. Create a new class file in your ASP.net project that inherits Page. Call it JorgePage. Then, make your codebehind file classes inherit JorgePage.
In JorgePage, write two functions:
private string getUsersDomain()
{
// returns the user's domain
}
protected string getUsersConnectionString()
{
switch (getUsersDomain().ToUpper())
{
case "ABC":
return Application("ConnecttoDB_ABC");
break;
case "xYZ":
return Application("ConnecttoDB_XYZ");
break;
}
}
Now, the function getUsersConnectionString() is available in the context of all your pages and returns the correct connection string. Furthermore, you have the code in only one place, so if you need to change the logic later, you can do so easily.
Given that you're using classic ASP, you can define a function to return the appropriate connection string in another .asp file and use the #include directive to add it to all your pages.
