Caché

Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. In the previous part, we created a basic front-end React application. In the second part of this article series I will show how to choose the right back-end technology for your application. You will see Caché allows you to use many different approaches to link your front-end to your Caché server, depending on your application's needs. In this part we will set up a back-end with Node.js/QEWD and CSP/REST. In the next part we will enhance our basic web app and connect it to Caché using these technologies.

A very simple SQL

SELECT field1 F1, count(field2) CntF2
FROM GCT.PA_Data
where field1 is not null
group by field1

gives an error back:

Is their a way to queue messages in a business operation to be processed later? I want to process messages over a certain size on a schedule, but let everything else process in real time.

what is mirroring??

Dear all,

In our application made in Caché object script, when we deploy some classes modified we have the option of calling "Purge queries" feature of Caché.

Is it possible to mimic what selenium does like navigating to a site and logging in  and filling out a form then logout in COS.I am trying to do that in COS using %Net.HttpRequest class or should I be using a diff

I have this code here;I am trying to read a csv file but when I run this code I get  <LIST>%open+3^%stream.

Are you ready for the next Advent of Code this year?

Just a few days left, the first puzzles will unlock on December 1st at midnight Eastern Time.

Hey Developers!

Good news! Just in time for the holidays, Gartner Peer Insights is offering customers a $25 digital Visa Gift Card for an approved review of  InterSystems IRIS or Caché this month!

We decided to support and double the  stakes. So! In December '18 you can get the second $25 digital Visa Gift Card for Gartner review on Caché or InterSystems IRIS on InterSystems Global Masters Advocacy Hub!

See the rules below.

This is the class which I want to test.

Class GSK.MyTestUnit Extends %RegisteredObject

I bet that not everyone familiar with InterSystems Caché knows about Studio extensions for working with the source code. You can actually use the Studio to create your own type of source code, compile it into interpretable (INT) and object code, and sometimes even add code completion support. That is, theoretically, you can make the Studio support any programming language that will be executed by the DBMS just as well as Caché ObjectScript. In this article, I will give you a simple example of writing programs in Caché Studio using a language that resembles JavaScript. If you are interested, please read along.

We are trying to get a custom header that I have added to a request to Cache, and I have seen the following in another post, however it doesn't work for us:

When using the JSON_OBJECT() function in Caché SQL on a %String property that contains JSON syntax, it converts the %String into a JSON object instead of escaping it as a string literal. How can I prevent this?

Is anyone in the fine community of developers who work with ISC technologies looking at Microsoft's Visual Studio Code offering?
