Hello everyone,

From now till the 25th of december each day 2 programming problems to sharpen your programming skills.

Theme this year:

The night before Christmas, one of Santa's Elves calls you in a panic. "The printer's broken! We can't print the Naughty or Nice List!" By the time you make it to sub-basement 17, there are only a few minutes until midnight. "We have a big problem," she says; "there must be almost fifty bugs in this system, but nothing else can print The List. Stand in this square, quick!

Let's say I have Macro.Parent class:

Include Parent
Class Macro.Parent
{

ClassMethod Test()
{
    write "Class: " _ $classname() _ $c(10,13) _ "Value: " _ $$$name
}

}

which references Parent.inc macro name:

#define name "Parent"

Now, I want in my subclass Macro.Child to have Test method with the same code, but to redefine value of name macro.

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, Community!

Deal with Dynamic (Schema-less) Data

With the release of Cache 2016.1, JSON support was re-architected and made part of the core object model with the creation of %Object and %Array classes, which allow you to create dynamic JSON enabled objects and arrays.

On a recent demonstration I was working on, I had the need to create a REST web service that returned a JSON representation of a persistent object.  After searching for methods that would allow me to accomplish this, ultimately I found none, until now.

With the release of 2016.

Let’s continue our series of articles about creating a web application using REST only.

Hi, Community! 

Please welcome a new session recording from Global Summit 2017:

Data Visualization: The Choice is Yours

In if condition what is the difference between specifying the single operator and double operator? For example, what is the  difference between (&& and &) or (|| and !)

In OS X 10.8 and earlier, PHP was built with ODBC support, making it easy to connect to a Caché database:

$ php -r 'phpinfo();' |grep 'ODBC Support'
ODBC Support => enabled

However, this support was removed in OS X 10.9:

$ php -r 'phpinfo();' |grep 'ODBC Support'

Some people use Homebrew, MacPorts, or Fink to get their tools back. If you're comfortable coloring a little outside the lines (i.e., using sudo and the command line), you can build the odbc.so or pdo_odbc.so extension (depending on which API you prefer), and use it with Apple's version of Apache and PHP.

I am trying to read an xml document using %XML.TextReader and that's is all well and l can get my elements values  but would like to determine where the next record start on the xml without referring to the document path in essence would like to use the same method to read different xml docs. I would like to know if is there a way or a function that I can use to get the start and end of a record in xml  as I would to get the start and end element.

Hello,

Is is possible to reorder the comments so we see new comments at the top? At the moment its very hard to find a new comments since the order of the comments is always from oldest to newest, if you comment on the first comment then your comment will be at the top while making a new comment on the post will be at the bottom. Also marking new posts with a different background color or highlighting them would be convenient.

This would be very handy for posts that are getting more comments than can fit on one page or just posts with more comments in general.

Thank you

Hi all,

I have a database with 140 million records containing financial transactions. When I do a query to calculate the sum of those records spanning a number of months it takes around 4 seconds on my database server which seems reasonable. However if I run the same query on an application server it takes around 40 seconds to do the same query.

In just this instance I would like to run that piece of code on the database server instead of the application server. It's a query that is only run a few times a day so I would prefer to have a fast result and don't mind putting a bit more stress on my database server for that.

Hi community,

I got quite a busy namespace with lots of services, processes and operations. The Ensemble purge that runs daily keeps the last 10 days. I would like to increase the NumberOfDaysToKeep to 60, but only for a small number of the interfaces in the namespace, and I would like to do it in a way that will be seamless to the users, so they will not have to change the URL of their calls, or will even be aware of the change.
The one idea that I had is to move these few interfaces to a new namespace , but how do I then do it without affecting the URL? with a Pass-Through interface somehow?

This might be a very simple rookie question but I'm trying to create couple of web services in Ensemble and using  document below as my tutorial, I do manage to do it:

http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY…

But instead of doing it as described above, where method signature is like this:

Method GetCustomerInfo(ID As %Numeric) As ESOAP.

I am trying to install cache 2017.2 on vagrant/VirtualBox and Ubuntu. I have tried both Linux precise64 3.2.0-23-generic #36-Ubuntu and Linux vagrant-ubuntu-trusty-64 3.13.0-137-generic #186-Ubuntu. I am getting an error that i can’t figure out. I have done this:

sudo apt-get install build-essential
sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get install libstdc++6
sudo apt-get install gcc-4.9 g++-4.9
sudo apt-get update
sudo apt-get upgrade

Any ideas on what to do?

Today %SYS.Namespace.ListAll started to report one namespace, for example USER, two times: once as "USER" and once as USER's database "^^c:\databases\user".

Details: my Cache instance has  50+ local namespaces. Today I have "touched" 3 of them (imported new classes), and now ListAll reports each of these 3 twice. Looks like ListAll is the only one who sees those strange duplicates, in all other places (Portal, Studio) only USER is shown.

Can someone explain what is happening?

We are starting to look into our BPL's and catch errors that calls may return. Can someone explain how to use the THROW and CATCH within the Business Process Language or have a sample of how it should work?

Thanks

I would like to write some code to parse a set of HTML pages from the internet in order to gather information from each web page.

All of the web pages are generated using a template, so the format of each of the web-pages is consistent with one-another and the information that I want to gather is always located in the same logical place within the page.

What is the best way to parse an html page in order to gather information at a specific place?

Can XML XPATH be used here?  Does anyone have any examples of parsing HTML content?

We are seeing something funky when using $ZSTRIP.

w $ZSTRIP("ZZZZTESTSLOCKTEST","<","ZZZZTEST")
LOCKTEST

Shouldn't this be returning....SLOCKTEST and not LOCKTEST, the goal is to remove ZZZZTEST from the beginning of the string.

THanks

Can anyone provide some sample in ObjectScripts to import a tab separate txt file into a SQL table?  I checked the document, there are two available classes, %SQL.Import.Mgr and %SQL.Until.Procedures, which one is better choice?

Thanks

Hello everyone,

i want an automatic unidirectional syncronization of multiple databases (some tables from .dat file, not the whole .dat file) . 

So far i have tried everything from package %SYNC and the best working class is SyncSet with journals and guids. The problem is initial database transport for example when i want to add another server.  The easiest solution i have found is to transport syncing globals ^OBJ.SYNC.N to another database and then call %SYNC.SyncSet.Import(), however it seems not to work with only the global structure, although it works fine using import files.

... but let’s first take a look at two relatively small topics, and namely:

Creation of a multi-page REST application

We only have one page for now. How about adding one more? Said - done.
