InterSystems Caché is a multi-model DBMS and application server. See more details here.

Hi developers!

I just want to share with you the knowledge aka experience which could save you a few hours someday.

If you are building REST API with IRIS which contains more than 1 level of "/", e.g. '/patients/all' don't forget to add parameter 'recurse=1' into your deployment script in %Installer, otherwise all the second and higher entries won't work. And all the entries of level=1 will work.

/patients

- will work, but

/patients/all

- won't.

Here is an example of CSPApplicatoin section which fix the issue and which you may want to use in your %Installer class:

    <CSPApplication Url="${CSPAPP}"
      Recurse="1"
      Directory="${CSPAPPDIR}"
      Grant="${RESOURCE},%SQL"
      AuthenticationMethods="96"
      />

How to write the home address right?

How Tax Service, OpenStreetMap, and InterSystems IRIS
could help developers get clean addresses

Pieter Brueghel the Younger, Paying the Tax (The Tax Collector), 1640

In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.

Hello InterSystems Community,

We're excited to announce that we've completed our first Open Exchange submission for InterSystems platforms.

BridgeWorks VDM is an ad hoc reporting and graphical SQL query builder application that was designed for any user who needs access to their SQL projections in InterSystems Caché, InterSystems IRIS, InterSystems IRIS for Health databases as well as access to InterSystems DeepSee and InterSystems IRIS BI Cubes with minimal SQL scripting experience.

Hello,

I have a very simple web service that I'd like to secure via SAML Authorization with X.509 Certificates. I am, however struggling with documentation and my lack of cryptographic skills. (I do this just for educational purposes now, but need to use it in the future)

Does anyone have an example that shows how to construct a SOAP Client with adding all necessary security headers manually or point me to a decent learning resource?

Thank you very much!

Hello Everyone,

I'm want to know, what is more common for your company to use, the abbreviation syntax or the complety name of commands, and why?

Ex.

S VAR=10 / D FUNC^ROUTINE F 1:1:1000

Set VAR=10 / Do Func^Routine / For 1:1:1000

set var=10 / do func^routine / for 1:1:1000

Here in my company, we are familiar with the abbreviation syntax, because to spell is more faster.

Portlets that use data from DeepSee


In the previous part of this series, we saw how to reference a web page that will enhance our dashboard experience. Now we will look into referencing data that is already in our cubes.

In this example, we will be referencing the controller object and we will be extracting data from it. This data will then be displayed as text in our Dashboard. In Part 5, we will show how to incorporate this data into other charting libraries.

In time for InterSystems Global Summit 2019 we at George James Software are pleased to offer a cloud-hosted evaluation environment where you can work with Serenji in Visual Studio Code, editing and debugging ObjectScript in a sandbox running InterSystems IRIS 2019.3 Community edition.

You can do it all from your web browser. Nothing will be installed on your workstation, nor will any settings have to be changed on it.

To take Serenji for a test drive please visit https://georgejames.com/dc-gitpod

Hi all,

I am trying to create a method to count the number of entries in a global, including all subscripts. I am having a bit of trouble getting the code to make it to the second subscript. When I get to the position where my key is "Canada" and I add a comma and empty quotes to it, it returns USA as the new key when I do the order function. Is the $Order or the global not able to use a single string to represent multiple subscripts?

Here is my global structure:

Good morning

I'm probably overlooking something very basic, but I'm running on Win2016 with Cache 2016.2 - All the work I am doing is in INT routines, but I'm making some calls to the Host File system using $ZF(-1).

I have a few mapped Network drives that are mapped in Windows, typically these are locations where I want to back up some files.

My process is quite simple:

1. Read data

2. Zip data files using RAR

3. Create folder on Network drive

4. Move RAR files to new network share.

I've tried a few different commands:

Studio source control hooks

Hi there,

I've been busy setting up Perforce source control on a Cache 2017.2.2.865.0 instance. Everything is mostly done and working through studio hooks. Checking out, modifying and checking back in works correctly but I would like to know what the hook, override, setting is to force studio to check if the class needs to be checked out or is already checked out by another user before you are allowed to edit it.

Hi all,

I wonder how to sync my server code to my local code using Visual Studio Code.

Previously, using Atelier, you could open a view of server and can copy the code to the current project, also if I change a BP, I could sync the code because I had a signal that It's warning me that there was a change and it needs to be updated.

I thing i shouls opening the ObjectScript: Explorer and select the code directaly, and right click -> Import and compile current file (Ctrl + F7)

If I use this command, the ouptut window shows:

Hi Community!

There are two general ways to execute arbitrary SQL in serverside ObjectScript code: EmbeddedSQL and ObjectScript SQL a.k.a. Dynamic SQL.

E.g. if we want to get the value of the property of instance with a certain ID using SQL we can do:

&sql(SELECT Name INTO :name FROM Sample.Person WHERE ID=1)

write name

Same result with %SQL.Statement:

set rs=##class(%SQL.Statement).%ExecDirect(,"SELECT Name as name FROM Sample.Person where ID=1")
  do rs.%Next()
  write rs.name

Hi!

I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns.

Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.

Here is my code:
