#Object Data Model

In reviewing the documentation found here, it states that there is an Attributes property. Since this is an array, I was wondering how I would go about traversing through the array to review what attributes are available on the file.

Is it possible to import a Cube from SQLServer (format .abf) in a Cache?

I have an .abf file and I want to open it in Cache. Is it possible?

Thanks

Hi everybody, We have written a convert from Punycode. This is reformed from javascript. Perhaps many non-English systems need to use this feature in domain name resolution. Anyone can use and change the code as needed.

Hi everyone

Is there any way to change a class definition (especifically a query definition during the compilation time)?
The idea is:
I have an abstract class with a parameter where I will define the ROWSPEC of a query and some methods to populate e temporary table
The implementation class will override the parameter, specifying the ROWSPEC of this implementation, and the methods will populate the rows in the same format as the ROWSPEC.

Hi!

I have a global-mapped class that I want to add a transient property through (or at least, not stored on the database). This property is the sum total of various charge classes that are linked to the class via child relationships.

I want this new transient property to be visible at least via SQL.

I am working with Caché Relationships.

I know how to iterate through the One side of the relationship and for each One iterate through all the various Manys.

What I have been trying to figure out, is the code (I can put into a Class) that will start at the top of the Manys, iterate down and for each of the Manys, pull the associated One.

I can do this with SQL or Globals, but I want to use only Class type code.

Is that clear? Any help?

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?

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.

This is a translation of the following article. Thanks [@Evgeny Shvarov] for the help in translation.

This post is also available on Habrahabr^ru.

The post was inspired by this Habrahabr article: Interval-associative array^ru→en.

Since the original implementation relies on Python slices, the Caché public may find the following article useful: Everything you wanted to know about slices^ru→en.

Note: Please note that the exact functional equivalent of Python slices has never been implemented in Caché, since this functionality has never been required.

And, of course, some theory: Interval tree^ru→en.

All right, let’s cut to the chase and take a look at some examples.

It is possible to update Cache object property from Python using the following Python code, with import of intersys.pythonbind3:

my_object.set("my_property",["A","B","C"])

However, I am unable to save 2D %List with 2D Python array like the following:

my_object.set("my_property",[["A","B","C"],["1","2","3"]])

I am not sure whether this is Python-Cache bind flaw or design issue. Is there any alternative/ workaround to do the same for above?

Hi all,

I have a non objectscript application connecting to a cache instance via ODBC and one column is a list of serial objects. The output from the query contains a lot of special characters and I'm hoping there's a better way to get this data back so I won't have to perform extensive parsing on the application side.

I've tried using the $ListToString() function, but that didn't help much, probably because the list contains complex objects rather than primitives.

Any help will be greatly appreciated!

Is it possible using MS Excel VBA to execute and retrieve data from a Cache custom class query? If so, how?

Hi,

I only use Caché and CSP, I am making a simple request in CSP page with #call method, and I have to define a callback of this #call method, can I do this?

This is my simple request in CSP page (javascript):

PainelBordoResource.prototype.obterIndicador = function(requisicaoParametros) {
let retorno = #call(painelbordo.PainelBordoResource.obterIndicador(angular.toJson(requisicaoParametros)))#;
return retorno;
};

Here's my issue. I've been using Sample.* globals and packages mapped to another development namespace to realize unit tests. So when I ran it, I notice that I forgot to start a transaction in order to be able rollback it to it's original data.

I assumed that I should use transactions since I was manipulating it's data but I didn't want it to be persisted.
