Tutorial - Working with %Query #1

The title of the contest subject is not quite precise but addresses the %Library.classes involved.
What is meant is officially named Class Query and is dating back to the early days of Caché.
CLASS is used because it is embedded in a COS class.
Though there is a precise description in the official documentation it remains rather abstract.
My tutorial should guide you step-by-step through a simple example in COS to make it tangible to you

We have a program set up in the HealthShare Facility Registry. And we have some patients enrolled into this program. In the HealthShare Registry management, we set up following consent policy for this facility (we call it program), Default Block Except: Block data except for the groups specified below, unless overridden by patient. There is no program in the Selected Programs so the consent should be applied to everybody.

We have a Cache database in Azure, and want to expose it as an OData source (link).

My first attempt was to use Microsoft's Visual Studio 2017 and Entity Framework to create the data models...but it seems as if EF and Cache don't work together. (I do have those instructions from 2013, but they don't work. (See other post. Best answer seems to be "migrate to IRIS 2019.1.")

Is there any other form of OData support?

Hello Cache Developers: I was curious if anyone has ever created a TWAIN interface to their Cache Application? I am new to TWAIN and hence the reason for this question. From what I understand, TWAIN is software used by various digital imaging software and TWAIN provides an API for applications to call to be able to import images into their application. I work with a healthcare application and was wondering what types of things are required for a Cache Web Application to call the TWAIN API to be able to load images into a Cache table. Any input, sample code, or suggestions is apprec

Hello; We are managing several Ensemble instances on several servers. One server has 4 instances, and two other servers have one instance each (those are production servers). We encrypt all instances using the Caché encryption in the management portal.

Currently we are using two different encryption keys: 1 key on the server with 4 instances, which is used for all 4 instances, and a second key on single-instance server. ( I'm installing the newest production server now.)

Hello everybody,

We have a piece of Caché software which calls an external utility using $zf(-1,command). It works fine under Linux, but under Windows an external process occasionally hangs (due to some internal problems out of the scope here) and need to be killed programmatically. Having PID, it's easy to kill a process. If a Caché process is called with JOB command, the caller can easily get its PID from $zchild, but alas $zf(-1) does not seem to return the similar info. Is it possible to get it somehow?

Hi Community,

I am trying to remove a duplicate OBX from a result, but I am running into some issues. Let me explain.

First I had a OBX where the observation Value had the blood type in it and the following OBX had the result in it.

The clients wants the blood type and the result in one field. therefore I merged / concatenated the observation values of the two OBX's.

I tried removing the OBX:2 but just cant take the whole segment out.

please see examples below

This is the result.

I am trying to use %INLIST in SQL query using a cursor and the query fails to return results. It appears that the variable I use against %INLIST returns an empty string. All the examples I have seen use result sets and build the query as a string. Is it possible to use %INLIST in a cursor-based query? Below is a a snippet of the code I am using:

Property mylist as %String (MAXLEN="") [InitialExpression = "route1, route2, route3"];

set routeList = $LISTBUILD(mylist)

&sql(DECLARE MyReport CURSOR FOR

SELECT

ProcessStartDate,

Have very little XML experience and have been able to manually create output. Have a need to take data that I store in a M global (example: ^TML("HDATA", ) and out put it in CCDA XML format.

Are there any examples of M code using the XMLWriter to accomplish this?

Or can anyone provide some guidance

Any help would be greatly appreciated.

How to shrink the IRISTemp database

InterSystems FAQ rubric

You can set the maximum size of the IRISTemp database at IRIS startup by setting a configuration parameter called MaxIRISTempSizeAtStart.

After setting, the system will truncate IRISTemp to the set value (MB) at the next IRIS startup. If the current size is less than the specified MaxIRISTempSizeAtStart, no truncation will occur. Also, if 0 is specified, truncation will not be performed, so the size will start without changing. (Default) Settings are made from the menu below.

Hi everyone,

Does anyone have any experience / examples of converting an .rtf file into an HL7 message (ORU^R01). My example is a histology report which is placed on a server to pick up and then convert if possible for downstream systems who receive HL7.

Struggling to find any sort of examples or even whether its feasible at this stage - there are certainly better knowledged people on here than me so thought id ask.

With thanks

Warren

We are using the Ens.Alert alerting process to send alerts (via email) to our external service desk application (Service Now).

Is there a way to suppress multiple alerts for the same error (within a specified timeframe)? (Either Rule or BPL?) (i.e. a system starts sending bad data which fails validation or is NAKd by a downstream system -- causing every message to create an Alert.)

Otherwise, every message creates an Alert, which creates a ticket in Service Now.

Thanks,

Brian

I'm working on a project were we are going to be receiving a non-HL7 formatted flat file that will contain a single result message per line and each result messages may contain repeating OBX fields that will need to be parsed out so that can be sent as an HL7 ORU messages that contains multiple OBX segments.

NewBie's Corner Session 17 New command

NewBie's Corner Session 17 New command

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

New command

The New command limits a variable's scope or range of use. In theory the New command is simple, in reality the New command is powerful and needs to be respected and understood. In Caché ObjectScript and MUMPS an entire chapter is devoted to it.

There are three variations of the New command:
