If I have defined a class query in one of my classes and I want to use that query from a method of another class, what are the pros and cons of using the %SQL.Statement interface versus the %Library.ResultSet interface?

I believe %SQL.Statement is the newer interface.

So if the old way is:

USER>s rs=##class(%Library.ResultSet).%New("%Library.File:FileSet")
 
USER>s sc=rs.Execute("c:\s\","*.txt")
 
USER>w sc
1
USER>while rs.%Next() {w !,rs.Data("Name")}

...

then the new way is:

USER>s oStmt=##class(%SQL.Statement).%New()
 
USER>s sc=oStmt.%PrepareClassQuery("%Library.File","FileSet")
 
USER>w sc
1
USER>s oResult=oStmt.%Execute("c:\s\","*.txt")
 
USER>while oResult.%Next() {w !,oResult.%Get("Name")}

...

Hello! 

I'm trying to run a simple SQL query in atelier but it complains about the manager.  I'm not sure if this is the best way to do it but here is what I got so far:

	ZNSPACE "User"
	
	SET domId = 1
	SET flister=##class(%iKnow.Source.SQL.Lister).%New(domId)
	SET myloader=##class(%iKnow.Source.Loader).%New(domId)
 
 
	SET myquery="select top(10) EntityValue, CorpusFrequencyAsRelation, CorpusSpreadAsRelation from %iKnow_Objects.EntityUnique  WHERE DomainId = 1 ORDER BY  CorpusFrequencyAsRelation desc"
	SET idfld="EntityValue"
	SET grpfld="CorpusSpreadAsRelation"
	SET dataflds=$LB("CorpusSpreadAsRelation")

	SET stat=flister.AddListToBatch(myquery, idfld, grpfld, dataflds)	
		IF stat '= 1 {WRITE "The lister failed: ",$System.Status.DisplayError(stat) QUIT }
	SET stat=myloader.ProcessBatch()
		IF stat '= 1 {WRITE "The loader failed: ",$System.Status.DisplayError(stat) QUIT }

In the documenations at this location http://docs.intersystems.com/enscomm20152/csp/documatic/%25CSP.Documati…, the normalize method applies normalizaion for text using the defined manguage and dictionary.

I want to normalize my iFind queries. How can I use the normalize method ? any code sample ? 

I want also to delete properly the iFind index. Deleting all the rows in the table is sufficient ? 

When quering iFind is it possible to get also TFIDF scores ? any code sample for this ?

Thank you for the help.

I have a tablepane in my Zen page that is tied to a class query.  When the page first loads, the table is empty.  A button onclick event causes the tablepane query to execute and load query results into the table.  I want an onchange event from a datalistbox to clear the tablepane so that it looks empty as it was when the page first loaded.  I have had no luck fiddling with javascript in the datalistbox's onchange.

A simple and rather automated search portal leveraging iFind capabilities for rich text search in 2016.1. It has simple faceting, result ranking, highlighting of search results etc and just works off any table you point it to that has an iFind index by appending ?t=MyPackage.TableName to the URL.

What is the best way to deploy DeepSee Termlists?

Has anybody managed to get Enterprise Monitor to work to monitor multiple namespaces on manay instances?

I am hitting an issue trying to get a local instance namespace working.

I have this error for my first local namespace sytem configured.

Hi, Community!

The Second Global Summit Free Registration Contest is running and we have only one week to celebrate new winner!

Here is current leaderboard amongst non-InterSystems DC Members after a half of the race:

(If you want to see contribution from InterSystems employees just set the filter value in the Deepsee dashboard)

John Murray contributed more than others last week.  John is a leader, but he did the result only for one week! 

There is one week more and so everyone can be a winner!

I need to perform additional checks before Cache user logins (let's say in a terminal for simplicity) and allow access only to those, who passed them. How do I do it?

I would like to know how to get the key value from a dropdownmenuitem placed on a navbar.

I have tried to get from onselect and onchange events of the template class, but it didn´t  work.

According to the snapshot attached I am trying to retrieve the values from 'action-1' and 'action-2'. 

I have attached a ZIP file with a snapshot which value I am trying to retrieve and example classes.

Thanks.

This advisory concerns the recently announced vulnerability CVE-2016-0800, aka DROWN, which is due to weaknesses in SSLv2. For more information, see https://drownattack.com.  This vulnerability may be relevant to InterSystems customers as InterSystems products have the capability to utilize SSLv2.

Hi,

Can a Cache Mirror be  used in the cloud ? (ie stand up a Primary and Backup member instances in a High Availability Cache Mirroring configuration) 

I'm investigating the validity of this configuration, because I was of the understanding that this may not possible due to these cloud servers not (typically) having fixed ip addresses, which interferes with the Virtual IP settings for the mirror set.

Is this correct, and if there are workarounds (like Load Balancing ?) can I have details on how this should be configured ?

Atelier Synchronization Logic

Background

Documents may be edited on the client independently of a connection to a Caché server. However, when a connection is established with a server for the purposes of saving, compiling and debugging code, then the client and server should agree with respect to the version of documents that are being operated upon. When they achieve this agreement, we say that they are “in-sync” and that the synchronization process is completed.

I have 2 projects in atelier, A and B which map to namespace A and B on the same server.

Namespace B has some classes mapped from namespace A.

I then edit a mapped class in project A  and save it(I can see the changes in cache studio as well).

atelier A:

studio:

However in project B the class does not change, even if I click the "syncronize all files with associated namespace " button.

atelier B:

I just saw this new posting by Mike Kadow on the "Caché, Ensemble, DeepSee" Google Group announcing the availability of his new book, "Caché and MUMPS - Part II"

There's also more information about it at his site http://www.cosmumps.org/

Hello good afternoon.
It is possible to change the background string " output " of the studio?
I would like to add a line in green or red line (TDD).

I am pleased to announce the next 2016.2 field test kit, 2016.2.0.609.0.

This is a relatively light update with only a few dozen changes from the previous field test, spread out across all areas of the product.  Also, in a break from the recent past, this update doesn’t contain any new fixes to problems found in the field.

Please download the kit and give it a try; the latest field test of 2016.2 is available HERE.  And, as always, we welcome your feedback.

There have been a few use cases recently within InterSystems where we've needed to connect to Caché-based web services from PHP. The first of these was actually the Developer Community itself, which uses web services as part of Single Sign-On with other InterSystems sites/applications. The following example demonstrates how to connect to a Caché-based web service (particularly, the web service in the SAMPLES namespace) from PHP, using password authentication.

When developing or maintaining Caché Objects applications, or even ones written in plain COS code, it's sometimes useful to investigate dependencies. Yuzinji is a tool that analyzes the Caché class dictionary plus the COS code within methods and routines, then feeds its results into Structure101g Studio.

By doing this it becomes easy to ask questions such as "Who uses this piece of code?", getting the information in a format that is easy to explore further. For example, I recently analyzed all the packages in the SAMPLES namespace of the 2016.

We are beginning a project to switch over to a differnt EMR for our inpatient system, and we are wondering if others out here have worked on a similar project and how did you handle your Ensemble environment?

Currently, we use one namespace for all of our HL7 interfaces. Has anyone used a separate namespace for a project to keep the build separate until go-live? What were the pros/cons for you using a different namespace? Or did you use one and what issues did you have because of it?

February 25, 2016 – Alert: Incorrect SQL Results InterSystems has corrected a defect that can cause incorrect results for certain SQL INSERT, UPDATE, and DELETE statements.

This defect is present only in Caché and Ensemble 2015.2 and HealthShare distributions based on them. The problem affects all platforms.

Incorrect results occur only when two or more of these statements are nested within each other.

The example below demonstrates one possible way for this problem to happen:

1. The class has an UPDATE trigger that uses embedded SQL to modify a table.

When my COS code is executing in a Caché process it might want to interact with the host operating system. For the purpose of this post I'm focusing on a Windows host, but much of it applies to other host OS platforms as well.

A common example of host OS interaction is when my process wants to read from or write to a file. What credentials will apply when Windows is checking whether or not to allow me access to the file?

To answer that we need to consider another question. How did our process start?

Hi

In studio when I right-click a package there is no option to delete it.

Also how do I upload an image to this post without linking to an external site?

If you've got more than one developer on a project, do you each work in your own namespace? Or do you all use a common namespace?

Through my work at George James Software I have encountered many different Caché and Ensemble development setups. At risk of over-generalizing, the older and more established users of InterSystems technologies seem more likely to have all their developers working in a common namespace, whereas the newer 'converts' tend to favour giving each developer their own namespace.

As I know Atelier sources already on github, but I think in private repository. May you say when this project will be opened, and how about if I want to contibute to this project?

Hello,

This package may be of interest...

Link: https://github.com/litesolutions/cachedb-import

I have programmed this over a hunch, in order to facilitate the retrieval of source code from a Caché installation. It makes use of the Java API provided by Caché.

Right now, I use it as a means to salvage sources in order to analyze them using the SonarQube plugin I develop for my employer. Unfortunately this plugin is not open source.

I am calling for help here, on two fronts:

• improve the code,
• obtain source samples to analyze!

Atelier shows the classes on server side as non editable grayed versions.

Is there a way to directly load class file from server and just start to edit that version?

RESTful API Call From Cache to Particle.io Electron

Tom Fitzgibbon | Multidata | 212-967-6700 x537 | tom@mul.com

Summary: Simple Blink Tutorial for Particle.io Electron Device from Cache

Electron device is a tiny ARM processor ($40-$60) that connects to Particle’s world wide leased 2G/3G network (about $3/mo) and runs off an included LiPo battery. Using Cache’s %Net.HttpRequest you can send/receive data, control hardware and read sensors.

Step by Step (about 1 hour)

1) Get the Electron from store.particle.io.

2) Set up the Electron from setup.particle.io.

Currently when class is saved in Atelier it is automatically saved on disk and on server (if there is an active connection).

Is there any way to save file with class or routine just on disk, but not on server?
