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.
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 !)
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.
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.
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:
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.
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?
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?
i come back to you , i've a problem with Client description in Oauth2, when i tick the Supported grant types and i save , there are not registred on the OAuth2_Client.Metadata table .
We are using Cache 5.0.15 version. We are facing error. I tried to copy the dat file, I am getting cyclic redudancy error.
I did run the integrity check and repair utility . Nothing works.
Now My question is how to recover the dat file with data.
Apologies if this has been asked already but I was not able to find it. When I look at the Add/Edit screen I see authentication methods of Password and Kerberos and am wondering if passing an identify file is supported.
I recently encountered a issue with Caché and I can't figure out where the problem is coming from.
I noticed that the license limit (200) was reached whenever I was opening my Studio (so it seems). When this occurs, I restart Caché (with the Cube in the Taskbar), and the number of license used is back to 1%, but grows back after. The time taken before the number of license grows back again looks pretty random.
I want to be able to import XML (say, using %XML.Reader) to Caché objects permissively (ignoring invalid/unexpected tags/attributes), but also to validate the same XML and list any/all invalid tags/attributes that it contains.
In this article I'd like to discuss asynchronous REST and approaches to implementing it.
Why do we need asynchronous REST? Simply put - answering the request takes too much time. While most requests usually can be satisfied immediately, some can't. The reasons are varied:
You need to perform time-consuming calculations
Performing action actually takes time (for example container creation)
etc.
The solution to these problems is asynchronous REST. Asynchronous REST works by separating request and real response. Here's an example, let's consider the following simple async REST broker:
Hi, I'm a student, weak programming. I ask for your help, I write a program in C #, there are two tables, but I do not understand how to organize the connection between them many to many. Table in DataGridView1 from DataSet1 on Form1 key connection in DataGridView1 from DataSet1 to Form3
It looks like Mumps is supported, and there is also an existing language with a .cls extension, which would account for why I see some very odd highlighting going on with some of my code.
There is a page on contributing a new language here...
