NewBie's Corner Session 3 More Read and Write commands & Multiple commands

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Write command with carriage return and line feed

When the exclamation point "!" is inserted after a Write command, a carriage return and line feed combination is produced. Note in this example, that a comma separates the exclamation point from the variable "X".

Hello, everyone!

I opened one project and there I found such lines as

$$Export^%occXMLExport(filename,"-d /diffexport",InternalName)

InterSystems is pleased to announce that Caché and Ensemble 2015.2.4 are now available as maintenance releases.

For a complete list of the corrections in 2015.2.4, please review the release notes.

Caché and Ensemble 2015.2.4 are available for the same platforms as 2015.2.3, with this exception:

Hello,

One of our AP would like us to provide the file upload/download sample code by using ZEN Mojo.

I already provided them the attached "upload-sample".

I tried to create the "download-sample" in a similar way, but I couldn't do it yet.

Does anyone have a good idea/sample about this?

I'd like to download the server side file(e.g. c:\temp\nene.jpg) into client machine with a OpenFileDialog(image.png).

Thank you in advance.

Hi!
There is interesting question in Stackoverflow.
This query works for MS SQL:

SELECT * 
FROM 
(
    SELECT *, ROW_NUMBER() OVER (PARTITION BY client_id ORDER BY date_updated DESC) AS rn
    FROM client_address
) a
WHERE a.rn = 1

There is one answer there, which solves the task:

I found a widget : Bootstrap Dual Listbox

At : http://www.virtuosoft.eu/code/bootstrap-duallistbox/ , which will
be very helpful in my application.

The problem is that I completely don't know & don't understand how to
install it & how to use it.

Using such a widget is essential for my application.

Thanks Simcha

Does the Caché installer do all of the necessary setup for using Atelier when upgrading a pre-Atelier instance?

I just upgraded an Ensemble 2016.1 instance to 2016.2 and the /api/atelier web application wasn't created automatically. Aside from creating this web application is there anything else that needs to be done to support Atelier?

** UPDATE **
See my comment below -- this was caused by a permissions problem during the upgrade. After fixing the permissions problem and upgrading again Atelier works.

NewBie's Corner Session 12 Do and Goto

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

InterSystems Caché provides a GUI (Graphical User Interface) based Integrated Development Environment (IDE) called Caché Studio. Developers can use Studio to create and maintain applications.

Controlling Process Flow

Controlling Process Flow means controlling the execution path of code. The execution of code flows from the top to the bottom in a routine, except for the following:

Does anybody know how can I get the DocumentId property from a DocDM repository using SQL?. So far my SQL is like this:

SELECT name,email,gender FROM JSON_TABLE(
'person',
'$' COLUMNS(
name VARCHAR(100) PATH '$.name',
email VARCHAR(100) PATH '$.email',
gender VARCHAR(2) PATH '$.gender'
)
)

Thanks!

Hi. This about a migration of code from a DEV environment to a PROD environment.

If an (under development) business host is Enabled in DEV environment and the production class is migrated across environments, this means that the Enabled status of the same business host in PROD would also become enabled (even if it may have been disabled before the update)

I am writing a static SOAP response to simply test connectivity. The end users is getting an error "Message: The processing instruction target matching [xX][mM][lL] is not allowed.", which I believe is related to white space. if I observe the response, it looks like there are two blank lines between the header and the body, which I'm guessing is the white space problem. But I can't seem to get rid of it.

Any ideas?

InterSystems has corrected a defect with Mirroring that can impact data integrity

The defect is present in all released versions Caché, Ensemble, and HealthShare beginning with 2015.2.0. It is present for all platforms and affects both failover and asynchronous mirroring configurations.

First post! In order to somewhat redeem myself for an unnecessary call to support, I've decided to post some classes that I've written to monitor certain metrics inside our Ensemble Live instance (yeah, Kyle, you WERE laughing at me, but it's okay). What the classes do is to run queries and code to get database sizes, status of the mirror, counts of rows in tables such as EnsLib.HL7.Message and Ens.MessageHeader. The data is collected and written to tables and then an email is sent out daily upon completion. I've found this quite useful in keeping an eye on what's going on. It's help

We have multiple implementations spanning many namespaces and edges. I would like to see if I could identify a single place, perhaps on HSREGISTRY or HSBUS, that I could capture certain events like searches (from all customers) and record transfers (with requester and provider).

The goal is to have a dashboard that would show simple stats such as searches by participant, records shared by participant and records consumed by participant. These are the 3 most important.

I appreciated the feedback on the other question of "how" but now I'm hoping to find the "Where".
