Hello,

I had an issue when using the method Exists, I noticed that if you provide a directory for this method it returns 1. This is really misleading, because sometimes the input could be a directory and the only way to predict this is to also test if the file is a directory.

I didn't tested using the Attributes method, but I supposed that this means could also be a solution for that issue. But still, I expected the Exists method to return 1 for files and 0 for directories, since there's also method called DirectoryExists already.

write ##class(%File).Exists("/InterSystems")
1

Would you guys

Hi all, 

I am trying to create a method to count the number of entries in a global, including all subscripts. I am having a bit of trouble getting the code to make it to the second subscript. When I get to the position where my key is "Canada" and I add a comma and empty quotes to it, it returns USA as the new key when I do the order function. Is the $Order or the global not able to use a single string to represent multiple subscripts?

Here is my global structure:

^Locations("Canada",1)="Montreal"
^Locations("Canada",2)="Vancouver"
^Locations("USA",1)="Michigan"
^Locations("USA",2)="Ohio"
^Location

Hi,

I want to do ordering dynamically in Query. I mean to say that order by value will not be hard coded in query, it will be passed in parameter.

I have tried to it following way, but it is not working for me. Can you please advise me how can I achieve it?

In below code, Order by :objSearch.SortingField is not working.

Class Query.ExternalUsers Extends %Library.RegisteredObject [ ClassType = "", DdlAllowed, Owner = {_SYSTEM}, Not ProcedureBlock ]

{



Query Search(objSearch As LISSystem.ModelView.UserSearch) As %SQLQuery [ SqlName = ExternalUsersSearch, SqlProc ]

Hello,

Is there a way that when you run $system.OBJ.Compileall() that you can make the output written to a file instead of the screen? I am trying to capture all the errors so I can review the code and fix them before we upgrade.

Thanks

hi,

i have two where-clauses:

a)  ... WHERE company=1 and product=7

b)  ... WHERE product=7 and company=1 

with other words the position of the where fields are swapped.

now the question is:

bring the where clauses a) and b) the same performance(queryplan) or do i have to write it in a special order???

in my point of view, there is a  parser/optimizer who cares about this, so i don't have to care about. 

Hello,

I have a small SQL question.  

Running an example queries in our Samples Namespace: 

1. select top 5 Description,Category from Cinema.Film order by Category - runs fine no issues and returns 2 columns as expected

2. select top 5 * from Cinema.Film order by Category - runs fine no issues and returns 8 columns as expected

3. select top 5 Description,Category,* from Cinema.Film order by ID - runs fine no issues, and returns 10 columns, with my first 2 repeated

4. When I try to combine the first 2 queries: 

select top 5 Description,Category,* from Cinema.Film order by Category

I get an error:

The Management Portal allows you to Export one or more globals to a file that you can then Import into that or another namespace.  However, the Management Portal can only be used to export entire globals.  For exporting selected nodes or subtrees within a global, a different utility is necessary.   This utility is the Export() classmethod in the %Library.Global class, which can export an entire global but also has the ability to export selected nodes or subtrees.

For example, consider this global named ^DATA:
^DATA(1)="ONE"
^DATA(1,2)="twelve"
^DATA(1,2,3)=123
^DATA(1,"two")="three"
^DATA(2)="TWO"
^D

Hi all,

We just encountered an instance of a result set RS and while looping through the results,  RS is getting overwritten when method 1 calls out to method 2 (in the same class).  Method 2 creates it own result set also named RS.     

This code is several years old and never had this problem.    When I changed the name of the result set variable in method 1 the problem cleared up.  

I though that variables were automatically 'newed' in classmethods. ???

We also recently upgrade to the latest Cache version from a much older version.    Is it possible that variable scope has changed across method

Hello Cache Developers!  The purpose for this post is to outline a coding challenge that I have encountered when trying to use shortcuts (i.e. CTRL+G) within a ZEN application.   Allow me to provide a summarized background:

Our application has a ZEN page (call it the PPL page) with a tablepane that displays a list of records.   This page also has an iFrame (#1)

• The tablepane allows the user to select one or more rows from the table and will click one of the appropriate buttons on that page to invoke a looping process that allows the user to work each of the selected records one-by-one.  
• Based on

Hello, has anyone tried to use Caché as a reverse proxy ?

We are trying to embed a dashboard server (Plotly Dash in this case, but it could be anything which runs on its application server) inside our application which is written in Caché.  
The dashboard/report server runs locally (for example, or inside a LAN) on port 8080, and has no authentication features, so we have to implement them on a different layer, and we'd like to use Caché for it.

We'd like to hide the dashboard server (port 8080 not exposed), and use it behind Caché, this way (putting it as simple as possible):

Caché should pass al

The DeclarativeCOS project is a heartfelt cry about programming in the COS language.

The purpose of the project is to draw attention of the public to improving the inner core of COS.

The idea of the project is the support of a laconic syntax for cycles and collections.

So what is this laconic something that I have come up with? Welcome to the examples below!

Examples

The key concept underlying the project is the declarative approach to writing code. You need to specify WHAT should be used and HOW.

I have personally always longed for a simple operator/command/magic spell in the COS termin

Hi folks,

My fist post here and a tricky question right away!

I have a remote MySQL database table ("SomeData"; not under my control), and a Caché-class (remote.SomeDataAccess) linked to it via ODBC using the link table wizard.

The remote table has a field "id" which is the primary key and an autoincrement bigint value. This has been considered in the setup and the generated class has an

Index MainIndex On id [ IdKey ];

which looks fine to me. The storage is

Storage GSQLStorage{<StreamLocation>^remote.SomeDataAccessS</StreamLocation><Type>%CacheSQLStorage</Type>}

I have a repository that I want to have in my /home/centos7/ directory, but it appears that Cache cannot access files there. Is that really the case? 

It seems like this is the case because in System Management Portal, when I try to up a new database in /home/centos7/, there aren't any directories listed, even if I add a custom one. Is Cache blocked out from this directory, and are there any others that Cache doesn't have the permission to access? 

Hello everyone!

hello guys, where could I be learning how to program in COS language? I need help please.

I need use/create an app based authentication class, best options on other languages is bcrypt, but on cache(2017.2) is not and option, any suggestion to construct this option ?

I am still working on a generic task where I need to apply journal file records to another database. Initially I didn't want to use Journal.Restore class methods as I need to perform some data transformation, and it seemed that the clearest way to achieve it was to read journal file record by record using %SYS.Journal.Record API. 

This approach worked (with some help from @Dmitry Maslennikov and @Eduard Lebedyuk), while it turned that the processing speed of %SYS.Journal.Record:List query was very slow, about 1MB of journal data per second on a mid-range server.

Therefore my second try was t

Hi Community!

Sometimes I meet a method which accepts 10+ parameters.

And often I need only the 8th parameter  to  pass. And I call the method something like:

do ##class(Some.Feature).Method(,,,,,,,"flag")

And I don't like this method when I call it like this cause, you know, often I just miss the number of commas and raise some other flag I wanted.

How do you avoid this situations? 

If you meet such a code, how do you call it and sure that you didn't miss the number of ","?

What is a good number of parameters in a method and f you need to pass more parameters in a method what do you do?

Good morning,
I'm working with a persistent data class and need to know which classes are evoquing it.
Is there a tool in the system to do it, similar to use the F12 key to follow a class?

I am trying out Atelier.  I have installed it and managed to get it to connect to a cache instance to test it.  I have created a local project and I am trying to copy the server files to it using the "Copy to Project" item on the popup menus.  I can copy both classes and routines to the project without issue, but when I try to copy the CSP files, I get the following message:

The documentation is not helping.  Can anyone throw some light on what is causing this?  I feel certain it is a misconfiguration or a setting  I have m

Hello everyone!

Does anyone know of a library that can be used to create Mock objects for Objectscript classes?

Right now, my team has been building mock objects by hand to help circumvent dependencies when writing and executing unit tests, but I always wondered if someone had ever created a Mock library like Mockito to help quicken the process. 

Thanks!

HI,

I have been using evaluation version of Cache 2017.2, it was working fine and I was using Cache studio, SMP  & Cache Terminal/console till yesterday.

Today, cache was in shutdown status, then I restarted.  But, Cache terminal is not working and showing as Access Denied while otherthings like studio and SMP is working as expected. I checked all security level services on SMP, all are fine and enabled.

Can anyone help me to diagnose the problem and make it working.

Thanks.
