#Caché

My fantasy didn't go beyond periodically running %SYS.Journal.System:Progress() class query, while I'd prefer to use an event handler of some kind. Any ideas?

Is there a system function/method which can create a GUID ?

What's the best way to replace character groups?

I want not to remove character groups as $zstrip does but to replace them with whitespaces.

$translate needs explicit character list.

Effectively I want to remove any characters besides letters, numbers and a small (known) subset of punctuation characters, replacing everything else with whitespaces.

If you’ve ever wondered whether there is a way to regulate access to resources in Caché, wonder no more. In version 2014.2 special classes were added that allow developers to work with semaphores.

Hi,

I am implementing free search text box, which can search data in all columns of tables.

I have created DisplayName column by concatinating two column data with space.

SELECT TOP ALL FirstName||' '||LastName AS DisplayName, UserType, IsActive, RoleName, DOB FROM LISDB.ExternalUsers

Now, in where condition I want to do like search in DisplayName column but it not working.

I have tried both fn CONCAT and  || in like query but both are not working for me.

Hello Everyone,

I want to Know Caché or IRIS has some way to communicate with DDE or RTD from Excel?

Att. Flávio.

I am new to cache programming language . I am facing below issue . please assist.

Question: One persistent class ID column is a combination of its properties (Roll No and Marks) [ Exact: RollNo||Marks]. When i am running the query from Management portal it is displaying data in the same format and data is there. But in the code if i am making below statement, i am getting null value.

Set ExistsID=##Class(User.School).%ExistsId(RollNo_"||"_Marks)

set ID=##Class(User.School).%OpenId(RollNo_"||"_Marks)

IRIS offers Durable %SYS Directory as a highly useful feature for working with containers.

Before inventing the wheel once more I'd like to know if a similar feature also exists for Caché / Ensemble.
Official documentation is quite silent about.
Though I have some names in mind that might know more about   ( @Luca Ravazzolo ?  @Dmitry Maslennikov  ?     @Eduard Lebedyuk ?  )

Would anyone please have an example of how to use the WriteSOAPBodyMethod method?

The webservice method I'm trying to overwrite the body looks like this:

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

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:

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.

We've just published an update to the Serenji extension for VS Code. Starting with this version (3.0.7) you can now debug the code that implements your REST services. Here's a taster:

Hello,
Having difficulty with sending POST request.

How I can send parameters in the body of request, if i'm using ContentType:"application/x-www-form-urlencoded".

Version of ensemble: 2010

My code is bellow:

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.

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. ???

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)

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):

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.

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 want to assign below query result into my Person class which have Name,DOB properties, and then  convert into JSON.

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!
