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.

VDM features:

Hi everyone. I'm new to cache, and i was looking for a command who reads a .txt file and store the informations in variables. I've found on the documentation the EnsLib.SQL.SNapshot class, and, even if i'm not sure if that's what i need, when i run the code it says that the class doesn't exist, but i couldn't find the right superclass to extend.

Transactions in Global InterSystems IRIS

InterSystems IRIS supports a unique data structure, called globals, for information storage. Essentially, globals are persistent arrays with multi-level indices, having several extra capabilities—transactions, quick traversal of tree structures, and a programming language known as ObjectScript.

I'd note that for the remainder of the article, or at least the code samples, we'll assume you have familiarised yourself with the basics of globals:

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.

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"
      />

Why log in to view pivot tables when you can have them delivered directly to your inbox? Are you in need of automated reporting for InterSystems IRIS Business Intelligence? Pivot Subscriptions is your solution: a tool for subscribing to scheduled email reports of pivot tables inside InterSystems IRIS Business Intelligence (previously known as DeepSee).

Database systems have very specific backup requirements that in enterprise deployments require forethought and planning. For database systems, the operational goal of a backup solution is to create a copy of the data in a state that is equivalent to when application is shut down gracefully. Application consistent backups meet these requirements and Caché provides a set of APIs that facilitate the integration with external solutions to achieve this level of backup consistency.

I am trying to make architecture for my project. And for it, it needs to make list property in which there is list of objects of another table, the data must be unique, therefore I make sql-query to check objects of another table if it is used or not, but I can't make sql-query to check elements in list in property with elements of another table. Can you help me? In property ID of object is used.

Hello everyone,

But if I want to search CompanyName have special char %, ex: '100% Co' , 'Group of Mr.%', 'The %TaxProp'...

How can I take % to query, with

In the previous article, I have demonstrated a simple way to record data changes. At this time I have changed the "Audit Abstract Class" which is responsible for recording audit data and the data structure where the audit log will be recorded.

I have changed the data structure to a parent and child structure where there will be two tables to record the "transaction" and the "fields its values" changed on that transaction.

Take a look at the new data model:

Pretty straight forward.

I'm tempted to hard-code ISO-8859-1 inside my VSCode extension when working with CSP because this seems to be the encoding used by default, but I need to know if there's any other possible configuration. So can you share your experience when working with CSPs? Like issues with encoding, discoveries regarding it, workarounds etc.

Also, can someone tell me if it's possible to work with UTF-8 encoded CSP files using Atelier without breaking the encoding of the output file?

Hi,

It turns out that on windows if you run a command with a windows command file you need to escape the % character as %%

In my case I could test freeze and thaw calls at the command line successfully as

..\bin\cache -s. -U%SYS ##Class(Backup.General).ExternalFreeze()

...but when my freeze script ran it would fail.

it turns out that a single '%' is striped when run in a windows command file, and it must be escaped as '%%' windows gets:

Hi,

I believe the healthshare Debug module did this (if you added it) but I no longer have access to Healthshare to look so am asking here.

Suppose I have;

Set fruit="apple"

set person="john"

d ..Something(fruit, person)

quit

ClassMethod Something(objs...) {

; Names of variables passed in

}

In side "Something" how can I see the original name of the variable passed in (i.e. know the variables passed in were called fruit and person and not just their values).

A few years ago, I was teaching the basics of our %UnitTest framework during Caché Foundations class (now called Developing Using InterSystems Objects and SQL). A student asked if it was possible to collect performance statistics while running unit tests. A few weeks later, I added some additional code to the %UnitTest examples to answer this question. I’m finally sharing it on the Community.

Hello community!

I have a question about the %OnSave method of a class. We have a class that has two properties that are classes.

Class A

Class B

Class C

Class A.PropertyB as Class B

ClassA.PropertyC as Class C

Classes B and C also need to point back to Class A - it's just the way it is. We need to be able to use any one of these classes and get to the others (it's actually even more complicated than this, as Classes B and C also have a PropertyC and PropertyB as well, respectively) :
