Hi, Community!

Someday you find yourself having a wonderful class package which can be helpful in several projects. So it is a library package.

How to make the classes available for different namespaces in Caché? There are two ways (at least two ways familiar to me):

1. Start the name of the package with %, like %FantasticLib.SuperClass. Wrong way.

If you do that the class would be placed in %SYS and would be available in other namespaces.

This is wrong because of the two reasons:

Hi, Community!

New 2018 Year is coming!

Hi, Community!

I'm pleased to announce that in this December 2017 we have 2 years of InterSystems Developer Community up and running!

Together we did a lot this year, and a lot more is planned for the next year!

Our Community is growing: In November we had 3,700 registered members (2,200 last November) and 13,000 web users visited the site in November 2017 (7,000 last year).

Thank you for using it, thanks for making it useful, thanks for your knowledge, experience, and your passion!

And, may I ask you to share in the comments the article or question which was most helpful for you this year?

Happy Birthday, Developer Community!

Hi folks!

Is there a one line command to map class package A to Namespace ASPACE?

Hi, Community!

It's November and we have a new Developer Community release!

What's new?

Hi, folks!

Consider I need to perform some logic which should fire because values of object properties has been changed.

Is there ANY reason for using class callbacks %OnBeforeSave or %OnAfterSave instead of Trigger?

Hi, folks!

Suppose you have a Caché class with %String property which contains relatively large text (from 10 to 2000 symbols).

The class:

Class Test.Duplicates Extends %Persistent 

{

Property Text As %String (MAXLEN = 2000);

}

And you have thousands of entries.

What are the best options to find entries which are duplicates on this property?
