The DeclarativeCOS project is a heartfelt cry about programming in the COS language.

The purpose of the project is to draw attention of the public to improving the inner core of COS.

The idea of the project is the support of a laconic syntax for cycles and collections.

So what is this laconic something that I have come up with? Welcome to the examples below!

Examples

The key concept underlying the project is the declarative approach to writing code. You need to specify WHAT should be used and HOW.

Hi folks,

My fist post here and a tricky question right away!

I have a remote MySQL database table ("SomeData"; not under my control), and a Caché-class (remote.SomeDataAccess) linked to it via ODBC using the link table wizard.

The remote table has a field "id" which is the primary key and an autoincrement bigint value. This has been considered in the setup and the generated class has an

Index MainIndex On id [ IdKey ];

which looks fine to me. The storage is

Storage GSQLStorage{<StreamLocation>^remote.SomeDataAccessS</StreamLocation><Type>%CacheSQLStorage</Type>}

Hi,

I'm sure I'm not the only one who's already assembling matching pairs of socks for this year's Global Summit in Boston later this month . In case you haven't registered yet or are still looking for the right justification to get the eventual approval to attend, here's a quick overview of all the sessions around Data Management and Analytics:

Hello everyone,
After some work with IRIS we want to share our ToolBox-4-Iris with you.

What is this about?

The ToolBox-4-Iris is an API for IRIS with a collection of handy and useful tools - features that are not available in IRIS, but greatly simplify application development. To save time and effort on the "typical tools" that every developer needs. This includes additional classes, individual methods or even more efficient macros, which are described in the respective packages.

Content

Macros
General ObjectScript macros, Status macros, National Language Support macros, and JavaScript macros.

I want to assign below query result into my Person class which have Name,DOB properties, and then  convert into JSON.

SELECT Name,DOB FROM Sample.Person

Hi Guys,

    I am new to Cache, I am trying to create an simple REST API on Studio and testing it with postman before that i have config the Web Application System > Security Management > Web Applications > Edit Web Application and i have attached my snapshot also with this post.

   When i testing it on postman i am getting "Service Unavailable" error. I really don't know where i did a mistake. I tried to console it on my code, when I the postman Url is not calling my code,So i think i did a mistake on my config part. Please give me some suggestion

Thanks in advance...

I have a repository that I want to have in my /home/centos7/ directory, but it appears that Cache cannot access files there. Is that really the case? 

It seems like this is the case because in System Management Portal, when I try to up a new database in /home/centos7/, there aren't any directories listed, even if I add a custom one. Is Cache blocked out from this directory, and are there any others that Cache doesn't have the permission to access? 

Hi

I  was wondering whether anyone can help I would like to know what is the underlying method that is used for exporting lookup tables from within studio.  I would like to do this programmatically.  The export function provided with Ens.Util.LookupTable is not compatible with studio.

Thank you.

Kind Regards,

Salma

I got below error when passing Date in timestamp format.

I am using %JSON.Adaptor. Please refer screen 2

Some time ago, InterSystems introduced the concept of %DynamicObjects.
This feature is a powerful tool that makes it very easy to convert any string of JSON text to objects and vice versa.
However, in the work that J2 Interactive is doing for our customers, there are a couple of things that "need some tweaking".

Hello everyone! 

Recently I search how to convert Cyrillic to Latin with Cache Object Script, but didn't find anything and decided to write ourselves, 

So here code: 

hello guys, where could I be learning how to program in COS language? I need help please.

I need use/create an app based authentication class, best options on other languages is bcrypt, but on cache(2017.2) is not and option, any suggestion to construct this option ?

Hi Team,

I am using %JSON.Adaptor class for Json validation.

Using below statement I got only one required field validation.(refer below screen)

    SET stat = objExternalUser.%JSONImport(%request.Content)

I need summary of all required field.

Hi Everyone!

New video, recorded by @Benjamin De Boe, is already on InterSystems Developers YouTube:

Scaling Fluidly with InterSystems IRIS

Hi Developers!

InterSystems Developers Community today unites more than 7,000 developers from all over the world. Since 2016, our community has been growing and improving for you, our dear developers! 

Together we've done a lot over these years, and much more is planned for the future!

So, who makes our community better every day? Who tries for all of us and improves the space for developers?

Let's warmly greet our team:

I need RowId of inserted record.

I have used below logic to get max row id,

but it will  not give desired result when multiple people enter record in the table at the same time.

I am still working on a generic task where I need to apply journal file records to another database. Initially I didn't want to use Journal.Restore class methods as I need to perform some data transformation, and it seemed that the clearest way to achieve it was to read journal file record by record using %SYS.Journal.Record API. 

This approach worked (with some help from @Dmitry Maslennikov and @Eduard Lebedyuk), while it turned that the processing speed of %SYS.Journal.Record:List query was very slow, about 1MB of journal data per second on a mid-range server.

Hi All,

I am currently looking for a way of exporting a project from within studio that would actually create the subfolders associated with it.  Is there an easy way of doing this.  Thanks in advance?

Kind Regards,

Salma

I am trying to work through our upgrading steps from 2015.2.2 to Health Connect 2019.1. Is there a place online I can access previous versions of Health Connect documentation? I am specifically looking for Health Connect 2018.1.2 documentation so I can understand the upgrade process on AIX.

Thanks

Hi Community!

Sometimes I meet a method which accepts 10+ parameters.

And often I need only the 8th parameter  to  pass. And I call the method something like:

do ##class(Some.Feature).Method(,,,,,,,"flag")

And I don't like this method when I call it like this cause, you know, often I just miss the number of commas and raise some other flag I wanted.

How do you avoid this situations? 

If you meet such a code, how do you call it and sure that you didn't miss the number of ","?

What is a good number of parameters in a method and f you need to pass more parameters in a method what do you do?

Hello,

I started a post when I tried to display a line graph on a dashboard:

https://community.intersystems.com/post/dashboard-line-graph

This did not work very well. I switched gears and now I have a Zen Page that includes a Zen Report in iFrame. However my line chart does not display a line.

This is my Report class:

Good morning,
I'm working with a persistent data class and need to know which classes are evoquing it.
Is there a tool in the system to do it, similar to use the F12 key to follow a class?

Can you please provide steps to debug in VS code using serenji and how to put break point in VS code, I have tried using F9 but it is not working.

I want to debug API code using postman.

I have BPL BP and BO.

To call BO I need to populate the stream property of the request message.

What's the best way to do it?

I have created below Add method in REST api, I got requested data in objExternalUser object but it is not saved to DB.

Using  "Write objExternalUser.%JSONExport()" I got JSON data.

Please refer below screen.

In System Management Portal, I'm on UnknownUser (which I've accidentally removed the %All role from), so I log out of UnknownUser and try to log in as root or Admin, but only see the following screen:
