Hi, folks!

I need to get the source code of a class installed on a remote server. I have no Studio or Atelier access to it but I can manage REST and Web terminal access.

What is the easiest way for me to make it?

Hi!

Recently GitHub introduced topics for the projects.

So you can change your InterSystems related projects introducing the  topics to let it be categorized, more visible and searchable. Here is the list of good examples for your projects (some of them are clickable already):

intersystems, intersystems-cache, intersystems-ensemble, intersystems-healthshare, healthshare, intersystems-iknow, iknow, intersystems-deepsee, deepsee, cache-objectscript, csp, intersystems-zen, zen.

If you have any good ideas for topics or already using something, please introduce it here in the comments?

Beginning - see Part 1.

3. Variants of structures when using globals

A structure, such as an ordered tree, has various special cases. Let's take a look at those that have practical value for working with globals.

Hi, Community!

Hope you have already put in your schedule the visit to InterSystems Global Summit 2017 which will take place on 10-13 of September in remarkable JW Marriott Desert Springs Resort and Spa.

This year we have Experience Lab, The Unconference, and 50 more other sessions, regarding performance, cloud, scalability, FHIR, high availability and other solutions and best practices.

Hi, Community!

We've just introduced 2 new rewards for members of the​ Global Masters - $200 (3,000 points) and $300 (5,000 points) discounts for​ Global Summit 2017.

Limit one Global Masters discount code per member. Code is non-transferable.

Quotes (1NF/2NF/3NF)^ru:

Every row-and-column intersection contains exactly one value from the applicable domain (and nothing else). The same value can be atomic or non-atomic depending on the purpose of this value. For example, “4286” can be

• atomic, if its denotes “a credit card’s PIN code” (if it’s broken down or reshuffled, it is of no use any longer)
• non-atomic, if it’s just a “sequence of numbers” (the value still makes sense if broken down into several parts or reshuffled)

This article explores the standard methods of increasing the performance of SQL queries involving the following types of fields: string, date, simple list (in the $LB format), "list of <...>" and "array of <...>".

Hello,

I'm currently exploring alternatives to CSP/services and ODBC/Sql Maps for access to Caché. I'm not seeing a library which would interest me, so am considering creating one myself.

Does 'CacheConnection' in C# use RPC of some sort, or a defined protocol to communicate with Caché, or does it do so over telnet with scripted commands? I would assume the former. If so, is this a publicly documented protocol that can be implemented by library developers?

Any guidance in this area would be appreciated.

Hi Community!

Check the new video on the. InterSystems Developers YouTube Channel:

Many Data Sources - One Application

hi

    I restored one database on Server B with EXTSELCT^DBREST command from   backup file (this backup file is taken from Server A).  

When I execute select some rows from one table,  it return error like this, 

the same select sql can return correct data  in server A

But when I select other rows from same table on Server B, it return correct data.

Why? maybe the backup file corrupted?

Thanks

I have a stored procedure like below:

Call USER.SP('select * from Sample.Person where SSN='aaaaa'','0','S')

How could I escape the single quotes for aaaaa? I try double single quotes but in vain.

Thanks you.

"SELECT  %SYSTEM.SQL_TableExists('table name') "could work as expected under SQL shell,

but for   "CALL %SYSTEM.SQL_TableExists('table name')" does not work (not any error reported, it just show nothing).

Is there any reason why CALL could not be applied to a stored procedure?

Thanks.

I needed to pass through a file with Ensemble but the operation wasn't writing some filenames as given because the  EnsLib.File.PassthroughOperation 'sanitizes' filenames removing characters that are not valid on some operating

Oh No! It has stripped out my semicolon and ampersand! I need them! (and they are valid filename characters in windows)

hi

  I execute sql from Terminal

SET result=$SYSTEM.SQL.Execute("SELECT TOP 5 name,dob,ssn FROM Sample.Person")

but I got error "<METHOD DOES NOT EXIST> *Execute,%SYSTEM.SQL"

Why?

Thanks

Hello. I am a student from Syktyvakar Forest Institute(Russia). 

I need to make Research : "Databases for working with spatial data
Consider MySQL, PostgreSQL and 1 to choose from". I want to explore Cache with subject library of spatial data.

Help.

Does Someone from the developers write the libraries of spatial data?

Caché offers a number of methods for going through a collection and doing something with its elements. The easiest method uses a while-loop and lets you fulfill the task in an imperative manner. The developer needs to take care of the iterator, jumping to the next element and checking if the loop is within the collection.

Hi

Has anyone worked out any tricks to overcome this issue in 2015 and IE11 where the Dialog content is masked. I'm trying to fix it in a custom one, but you can see that the same issue is happening in the Standard Color Selection one as well.

Hi everybody, 

I have to create a pivot that shows the result comparing the last week of the current date with the last week of the last year in the same month. I tried using the function LAG, but didn´t work.  Works only if I want to compare the months between the two years.  If someone has some idea, i will appreciatte a lot. 

Thanks.

Good day, I have this issue. I have global like: ^myglobal(varX) = $LB(var1,var2). I need to delete all globals that have variable var1 in that list same without a need to iterate through all globals and checking their value.

Exact example:

- in database exist following:

I know this may sound like sour grapes, but really it is not.

I hear all the exciting things about the up coming InterSystems Conference, and I am sure it is.

But it is way, way out of my price range, and I am sure out of the price range of most of the Cache/MUMPS developers, without company backing.

Just wondering what others think.

Is there an available API for creating a business service? Is it just a table that Business Service Wizard is inserting the data into or it is something more? 

Good day, I would like to find out the size of Caché ObjectScript variable in order to guarantee that my program will not leak, equally in terminal and Caché globals.  For example how huge number I can store in that variable ? And what happen in Caché when variable will leak ? How is this behavior treated? (how much memory is reserved for common variable?)

Thanks  in advance for your answers.

How do we generally create an error object of %Status?

Set status=$SYSTEM.Status.Error($$$GeneralError,"Something went wrong")

Now, like $$$GeneralError there are many more macro defined within %occErrors include file by Intersystem which we can use.

In my cache studio i couldn't find the a namespace of iknow so how can i check is my studio version is compatible to to the one i am using now. If i don't have one then can be able to create a new namespace in studio?

Hi Every Body

I have created a class that extends file operation, but can't find the object that has the value for the file path. Is that object in pRequest or is there an another object I should be used to see that value?

Hi.

It is easy to receive JSON representation or dynamic Array from %ListOfDataTypes:

set l=##class(%ListOfDataTypes).%New()
do l.Insert("a")
do l.Insert("b")
do l.Insert("c")

set arrStr=l.$toJSON()
zwrite arrStr
set arr=l.$compose([])
zwrite arr

How to make backward conversion? How to receive %ListOfDataTypes from dynamic Array an JSON string?

I've tried

Here is an idea that would make the Developer Community immensely more valuable (to me anyway)

Have the capability of getting Listing output from searches or tags or groups.

In addition, have people put titles on their answers and comments,

And having a detailed list with all the answers and comments if needed

Then being able to sort the list by date or other criteria.

Something like:

Sub1 . . . .

-answer . . .

-comment . .

-answer . . .

Subject2 . . .

Hi, we are trying to deployed a changed schedule to our DEV instance (from our TST).  And are getting an error:

Dear All,

I would like to block ADT_A18 and ADT_A47 HL7 2.3 messages with an empty MRG:1 field.

This is to prevent my current HL7 ADT router (Business process) sending blank Merges downstream.

I've attempted to create a business rule where this would return out the business role process.  However the messages still loop though the other rules.

Any advice would be great.

Kind Regards

Stuart
