I have two classes:

Class Example.Parent Extends %PersistentProperty 

Child Extends %Persistent

A parent can have many children. I want to query for parents and add children for each parent to my result.

Here is the code that I query with:

In the QueryParents method, while iterating through the result set, I trigger a new query for each parent to find the children. And at the end I return a JSON structure. Now, this works but it is not going to scale well when there are many records in the database.

Is there a better approach to doing this?

I have version 2017.2 installed.

Hey Developers!

Do you want to reap the benefits of the advances in the fields of artificial intelligence and machine learning? With InterSystems IRIS and the Machine Learning (ML) Toolkit it’s easier than ever.

Join InterSystems Sales Engineers, @Sergey.Lukyanchikovand @Eduard Lebedyuk, for the Machine Learning Toolkit for InterSystems IRIS webinar on Tuesday, April 23rd at 11 a.m. EDT to find out how InterSystems IRIS can be used as both a standalone development platform and an orchestration tool for predictive modelling that helps stitch together Python and other external tools.

Hi Community!

All,

I've been following the " Build your First application with Cache " Learning path and followed to steps for installing the Atelier eclipse plugin.

It appears that the repository for the plugin is missing the "content.xml" file.

Hello,

1)

I am trying to have a ZEN datacombo to display list of Namespaces column using a Class Query.

<dataCombo id="NamespaceId" queryClass="%SYS.Namespace" queryName="List" showQuery="true" />
This Classquery works fine in <tablepane> and also from terminal.

But the datacombo is not displaying the "Namespace" column but only the last two columns. I have tried property displaycolumn="1". But this is not working.

Thanks in advance.

Regards,

Jimmy Christian.

Hi,

I have a global that holds users name and date of birth.

I would like to loop through them and check if the date of birth is more than 2 years based on todays date

so I have ^checker("under2", "Eric David", "02-05-2018")

I want to check the birthdate based on todays date to see if it is greater than 2. How do I access the birthdate in the global

Please can you advice

I tried :

set values = $order(^checker("under2"))
set td = $zdate($horolog, 3)
set ol = $p(^checker("under2"), ",", 3) // this does not work
while (values ' = "")
{
set difdays = $system.SQL.DateDiff("d", ol, td)
if difdays > 730
{    
set ^value("greater than 2")
}
}

What is the process in importing a role from one server to another server?

Let's say Server A is our main server that we maintain all of our resources / roles / users. We would like to get these over to Server B, Server C, Server D, etc.

It looks like when we import, there are tables and resources left in the destination servers that are not in the source server. It looks like whatever was in the destination server that was not part of the source server was not deleted from the import.

What is the proper way of exporting/importing a role so that this does not happen?

I managed to use CacheGlobalOrder to iterate over global and return the next subscript:

int GetGlobalStr(char *global, int subscript, CACHE_EXSTRP result)
{
    int push = CACHEPUSHGLOBAL(strlen(global), global);
    int pushS = CACHEPUSHINT(subscript);
    
    // narg Number of subscript expressions pushed onto the argument stack.
    int narg = 1;

    // Direction for the $Order is 1 for forward, -1 for reverse.
    int dir = 1;
    // Indicates whether the data value, if there is one, should be returned.
    int valueflag = 0;
    int order = CACHEGLOBALORDER(narg,  dir, valueflag);

    int pop = CACHEPOPEXSTR(result);
    //pop = CACHEPOPEXSTR(result);

    return ZF_SUCCESS;
}

Hi guys!

Portrait of  Madame X, Gustave Caillebotte.

One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.

Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.

The trick is how you transfer an array to work with into a function. 

One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator. 

Below you can find a very simple example which illustrates the thing.

Hi, We recover a large amount of data from an external database (SQLServer, about 1 million rows in JDBC).
However, we have treatment time issue.
This process takes more than 30 minutes whereas on a "classic" SQL Server Management Studio type request takes less than a minute.

While searching on the internet, I came across this article: http://makejavafaster.blogspot.com/2015/06/jdbc-fetch-size-performance.html
It explains how in Java, we can tweak the FetchSize parameter of the JDBC driver to optimize this kind of process.

Is there a way to access this JDBC parameter through the EnsLib.SQL.

Between Aix(backup) and Windows(recovery) , How to do this?

We use a lot of external MS SQL calls to look up numerous things when it comes to HL7. I am running into an issue where the outbound calls are queued but the message is sent onto the next process before it gets a response. How do I get it to wait till the response gets back from the MS SQL call before sending it onto the next process?

Below is a screen shot of what I am trying to explain...Select Research Study executes at 8:33 the message is sent to the next process at 8:34, but the response of the MSSQL call doesn't come till 9:31.

Hello everyone

I have a server configuration in a CSP Gateway installed on a PC (let's call it S2) different from the main one (let's call it S1). This configuration allows me to access a web application that is installed on S1, from a client C asking S2 for this webapp. But for now it works only in HTTP between C and S2, and we would like to use HTTPS (as it already works between S2 and S1).

First here are the tutos found in the doc:

https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KE…

Hello gentlemen,

I have to create a objectscript program that will simulate a mainframe (because it's going to be removed). For my program, I receive data from another program that is written in Delphy by TCP on a preset socket.  Here is my problem, how can I handle this? 
Which class shoud my program  extend?
Which Adapter should I use?
My program must be able to read what the delphy one is sending and i don't really know what structure it is in what it is in. So is there a class that can allow me to read it? Thanks for your future anwers.
Here is a sample of what I have thought but doesn't work.

Continuing on from my last post, I am posting my succesful output for the Day 2 Part 1 below.

A brief description of this exercise is that you receive a sequence of strings.

You have to count the if any duplicate or triplicate chars exist in the string.  Multiples will exist, but if you find multiple ldupicates / triplicates you will count them once.

At the end of sequence of strings you have to SUM the no.

Hi Community!

Here is the changelog of new features and bugfixes of DC engine in March 2019.

New features:

• Open Exchange promo block
• Open Exchange button in Article
• Github and LinkedIn profiles for a member

Plus we solved a few annoying bugs and possibly introduced some new)

See the details below.

In Cache'/Ensemble, by specifying the objectsPackage parameter, dictionaries (and other objects) get projected to tables that can be accessed by SQL queries.

But in IRIS (IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2019.1 (Build 507U) Mon Feb 25 2019 13:47:16 EST), when I created a dictionary with ##class(%iKnow.Matching.DictionaryAPI).CreateDictionary(), it does not get projected to a table.

The class APIs correctly retrieve information about this dictionary.

Am I missing something with IRIS, or is there any issues about this?

I would like to pass multiple values of a FILTER from one DeepSee DASHBOARD to another DeepSee DASHBOARD. The documentation indicate this can be done via an URL. Are there any examples this type of configuration?

I needed to know programmatically if last ran failed or not.

After some exploring, here's the code:

ClassMethod isLastTestOk() As %Boolean
{
  set in = ##class(%UnitTest.Result.TestInstance).%OpenId(^UnitTest.Result)
  for i=1:1:in.TestSuites.Count() {
    #dim suite As %UnitTest.Result.TestSuite
    set suite = in.TestSuites.GetAt(i)
    return:suite.Status=0 $$$NO
  }
  quit $$$YES
}

We are pleased to announce the availability of HealthShare 2019.1.

Hello All,

There are few tools for SQL optimization available and even query builder has Show Plan to give us an estimation of the resources needed to execute.

For Methods - Is there anything similar ??

I would like to see a similar approach as to the time taken for method to execute.

Is Studio Debugger only option ??
