Hi,

I'm using node.js to access to Iris.

Considering this globals:

^Customer(1, "Address", 1)="London"

^Customer(1, "Address", 2)="UK"

^Customer(1, "Name")="Jane K. White"

^Customer(2, "Address", 1)="Reigate"

^Customer(2, "Address", 2)="UK"

^Customer(2, "Name")="Peter R. Black"

^Customer(3, "Address", 1)="London"

^Customer(3, "Address", 2)="UK"

^Customer(3, "Name")="Paul J. Green"

I retrieve all customers with: 

mydata.retrieve( { global: "Customer" },

"array",

function(error, result) {

if (error) {

// error (see result.ErrorMessage and result.ErrorCode)

} else {

// success

} } );

How could I retrieve just the

Tabular data storages based on what is formally known as the relational data model will be celebrating their 50th anniversary in June 2020. Here is an official document – that very famous article.  Many thanks for it to Doctor Edgar Frank Codd. By the way, the relational data model is on the list of the most important global innovations of the past 100 years published by Forbes.

On the other hand, oddly enough, Codd viewed relational databases and SQL as a distorted implementation of his theory.  For general guidance, he created 12 rules that any relational database management system must comply with (there are actually 13 rules). Honestly speaking, there is zero DBMS's on the market that observes at least Rule 0. Therefore, no one can call their DBMS 100% relational :) If you know any exceptions, please let me know.

Let's say I have this property:

Property FavoriteColors As List Of %String;

I heed to convert it to JSON using SQL or at least without object access (so direct global access).

What's the fastest way to do that?

I thought about JSON_ARRAY and JSON_ARRAYAGG sql functions but they don't do that.

Hi Community!

Here is the digest of what has happened on Open Exchange in November and December 2018!

Application Releases

We had 5 releases in November and December:

Cache ODBC for Node.js

This library aims to provide simple access to ODBC data sources for node.js.

Laracache

Laravel package providing InterSystems Cache as a data source using ODBC

DeepSeeButtons

Tool for analyzing your DeepSee Environment

DSW Reports

Addon for DeepSee Web which provides online reports and PDF emailing reports using InterSystems DeepSee dashboards

AnalyseThis

Utility to easily transform a CSV file into a personalized preview of DeepSee

I have an in-memory list of items and I want to check which items match my pattern string.

Pattern string is a comma-separated list of items and special symbols like '*' and maybe '?'.

There's something similar in $system.OBJ.Compile, it accepts patterns: "*.data.*,Sample.*" -  and it would compile 'Sample' package and all 'data' packages.

For example:

set list=$lb("abc", "c", "aaa", "bbb")
set result = ..match(list, "a*,*b")
zw result
result=$lb("abc","aaa","bbb")

Hi there,

I've been busy setting up Perforce source control on a Cache 2017.2.2.865.0 instance. Everything is mostly done and working through studio hooks. Checking out, modifying and checking back in works correctly but I would like to know what the hook, override, setting is to force studio to check if the class needs to be checked out or is already checked out by another user before you are allowed to edit it.

I need to convert timestamp into HTTP-date as defined in section 3.3.1 of [RFC2068]. HTTP-Date can have several representations, but preferable view is defined by RFC 822, updated by RFC 1123 and looks like this:

wkday "," SP date1 SP time SP "GMT"

Here's an example of HTTP-date value:

Sun, 06 Nov 1994 08:49:37 GMT

The problem I encountered, is that if server locale is not English, then $zd, $zdt and TO_CHAR return localized names of weekday and month (i.e: Вос). Is there a way to get English names of weekday and month regardless of server locale?

Just checked TO_CHAR and it also calls $zd.

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.

I have a persistent class.

I want to store one of the properties there as a stream or a string depending on a size.

99% of values would be strings (less than $$$MaxStringLength characters) so I don't want to store everything as streams.

What do you think of this approach?

What's the best architecture to implement in this situation?

Hi Everyone!

New session recording from Global Summit 2018 is available on InterSystems Developers YouTube Channel:

Automating Enforcement of Code Standards

At the George James Software booth at Global Summit last year we took the wraps off the work we've been doing to make our popular editing and debugging tool Serenji available on the Visual Studio Code platform.

Rather than requiring you to pull code from your namespaces into local files, then push the changes back to the namespace to run it, you work directly in the namespace. In other words, the editing experience is like Studio rather than like Atelier.

As well as editing code you can also debug it directly from VSCode.

We're now looking for people to test a pre-release.

Friends , can anyone help in how to kill instances of a business process? We have searched the documentation and looked in the Production, We am not seeing how to perform this task.

Hi,

We are using Cache to generate HTML pages (complete with Javascript), which we are reading in an Android phone App's WebView.

If, when we generate HTML as follows:

<html>

<body bgcolor='red'>

Hello World

</body>

</html>

Reading this is iPad gets what you would expect, a red page with Hello World written in it.

However in Android phone, the page is both white and blank.

What stumps us is that for Android, if we intercept the call in the csp page that generates the html, and we redirect the call to another (cache) page's url (ie another csp page), the whole of the content of the new Url is displayed

 Hi Community,

  I am using a method taht calls a Dashboard in Deepsee web  from an application , but I want to know if it's possible  to not showing the header, this part that have the search button, the name of the namespace, etc..

This is the method : 

Method %OnAfterCreatePage() As %Status
{
    //Set contratistaId = $Get(%session.Data("ContratistaId"),"")
    //Set gerenciaId    = $Get(%session.Data("GerenciaId"),"")

    //Set filter1 = "&SETTINGS=FILTER:Gerencia.Gerencia.idGerencia."
    
    //Set urlBase =

I've mapped multiple tables (UNION on mapped SQL classes) into a view, using CREATE VIEW.

Through ODBC, in Entity Framework, I am querying against that view and offering paging. The paging is implemented using IQueryable.Skip and IQueryable.Take. 

Skip seems to have unexpected results, I believe due to incorrect SQL generated by the Entity Framework provider, though perhaps I've done something incorrectly. The generated SQL looks similar to this (with some bits replaced or altered for security reasons), the basic structure is unaltered.

SELECT TOP (2) * -- "2" is the number of records per page

This is a quick note on what happens when, on your CSP page, you call a cache script which returns a %Boolean and store that value in a javascript variable.

When you call a script with language="cache" and returntype="%Boolean" from a javascript script, the return value is interpreted as a string, not as a boolean.

Here's an example:

A cache script that returns (in theory) a "false" value:

<script language="cache" method="giveMeAFalse" arguments="" returntype="%Boolean" procedureblock='1'>
return 0
</script>

A javascript method that logs what the value's actually interpreted as:

<script language="ja

I'm writing a SOAP client in Ensemble (2017.2.2) that is required to pass empty elements to the SOAP server in the form <xsi:type="ns:ResponsibleUser"/> where ResponsibleUser is a class that itself has no properties.I initially thought I'd found the answer with the XMLIGNORENULL parameter of XML enabled classes but this didn't make any difference for SOAP requests, only working when I wrote the XML to a file.

After attending the Intersystems DACH conference in Germany at the end of last November and taking part in a few workshops about containers and microservices I took the plunge and installed Docker on home Windows PC, downloaded IRIS 2018.2 preview and got that up and running. Good stuff and I gave myself a pad on the shoulder at that point.

But then it dawned on me that I couldn't edit code using Studio as  Studio is Windows only and while I'm running on a Windows desktop the Docker image itself is Linux based.

Hi Community!

Here is the digest of the most popular videos on InterSystems Data Platforms we published in 2018 on InterSystems Developers YouTube Channel!

And! 

Please check the most popular videos by Watch Time. See the details below. 

I have an sql statement that I would like to execute but I get the error

"zSearchChanges+5^MergeHyland.TypeTwoUtil.1 *KeyID"

and here is my sq

l  "&sql(SELECT Key INTO :KeyID FROM MergeHyland.TypeTwoDimesionalTable WHERE Key = :Key)" any ideas why 

Found a strange documentation block about Python bindings in Chapter 3.6 of the Caché manipulation functions with time and date. It looks like this text accidentally copied one to one of the Perl binging documentation. It's funny that the packages of functions called PTIME_STRUCTPtr, PDATE_STRUCTPtr and PTIMESTAMP_STRUCTPtr is suspicious for Python :)  

On the other hand, nothing is said about the functions parse_time, parse_date, parse_timestamp, which are present in /dev/python/intersys/pythonbind.py ahhh!

Has anyone encountered this problem?

I would like to know if there is a built in function that checks a value in the rule editor to see if it is numeric.

I loaded 2017.2 onto a windows desktop that I was going to use for testing. I need to now uninstall 2017.2 but when I do I get a ERROR saying it can not find the INSTANCE name, when there is HEALTHSHARE defined.

Has anyone else had this issue? I would like to uninstall this version and start over from scratch without having to re-image my machine.

Thanks

Scott

Hi all,

Does anyone knows if there is a limit per second adding messages to an Ensemble queue? I have a Business Service working and sending async requests to a Business Process, but I can't reach no more than 60-70 messages queued per second.

I've done several tests and same behavior seems to happen with all our productions. So I was wondering if there is a parameter anywhere to maximize the number of requests that can be send to a queue per second.

I was wondering if anyone has ever created a unit test which would run testing a mac routine (old fashion), via 

Hi Community!

New Badges're already on Global Masters Advocacy Hub! 

We're happy to announce that this year we again introduced three annual badges on Global Masters Advocacy Hub to let you remember how much you contributed to Developer Community in 2018. Here they are:

✔ DC Best-Selling Author 2018
✔ DC Expert 2018
✔ DC Opinion Leader 2018

Let's take a closer look at the DC Wall of Fame 2018 and greet everyone with big applause! 

This code snippet sends an XML request to a server and saves the response to a file. The class method "test" runs the code:

Class objectscript.postXML
{
	classmethod test() {
		Set HTTPRequest = ##class(%Net.HttpRequest).%New()
	    Set HTTPRequest.ContentType = "text/xml"
	    Set HTTPRequest.NoDefaultContentCharset = 1
	    Set HTTPRequest.Location = "ITOMCZ"
	    Set HTTPRequest.Server = "wph.foactive.com"
	    Do HTTPRequest.RemoveHeader("User-Agent")  
	    Do HTTPRequest.RemoveHeader("Accept-Encoding") 
	    Do HTTPRequest.RemoveHeader("Connection")
	    Do HTTPRequest.SetHeader("Expect","100-continue")
    Set RequestXML = ##class(%Library.File).%New("c:\test.xml")
    Do RequestXML.Open("RS")
    Do HTTPRequest.EntityBody.CopyFrom(RequestXML)
    Do RequestXML.%Close()
 
    Do HTTPRequest.Post(HTTPRequest.Location)
 
    Do $System.OBJ.Dump(HTTPRequest)
    Do $System.OBJ.Dump(HTTPRequest.HttpResponse)
 
    Write HTTPRequest.HttpResponse.Data.Size
    Write HTTPRequest.ContentLength
 
    Set ResponseStream = ##class(%Stream.FileBinary).%New()
    // Second part is typically the file extension, i.e.: application/pdf -> pdf
    Set FileType = $Piece(HTTPRequest.HttpResponse.GetHeader("CONTENT-TYPE"),"/",2)
    Set ResponseStream.Filename = "C:\test."_FileType
 
    Write ResponseStream.CopyFrom(HTTPRequest.HttpResponse.Data)
 
    Write ResponseStream.%Save()
    Do ResponseStream.%Close()
}
}

This is a posting about a particular feature of Caché which I find useful but is probably not well known or used. I am referring to the feature of Language Extensions.

This feature allows you to extend the commands, special variables and functions available in Caché Object Script with commands, special variables and functions of your own. This functionality also applies to other languages the Caché supports at the server, including Caché Basic and Multivalue Basic.  

Why would I need or want to add new commands ?

There are a number of use cases.

This post is intended to guide you through the new JSON capabilities that we introduced in Caché 2016.1. JSON has emerged to a serialization format used in many places. The web started it, but nowadays it is utilized everywhere. We've got plenty to cover, so let's get started.
