#Caché

I have a class that has a list property, which contains a list of other objects, and I want to join against it in SQL.

Class Foo Extends %Persistent
{
Property MyBars As list Of Bar;
}

Class Bar Extends %Persistent { Property Name As %String; }

Simply querying the Foo table, I see that MyBars looks like a $LIST, so I tried using a query with the %inlist operator but that didn't seem to work as expected. The following query produces zero results:

select bar.name from foo join bar on bar.id %INLIST MyBars

Is there some convenient way to do this sort of join?

Hello,

we have to implement some application logic using either Java or .NET. Which should we choose? Given that all other considerations are equal, which is in your experience better way performance-wise to interact with external components in Caché: .NET Gateway or Java Gateway?

Thanks.

Hi

Please can someone send me an example of how to auto refresh a table pane. 

Thanks

Hi-

I have an IP address (or hostname) and a port (in this case a super server port #) and I want to try to verify that network communications can be established between the host I'm on and the given hostname and port number of a remote server.

Is there any way pragmatically to do this within Cache?

I am trying connect DB using Oracle DB link (ODBC).  I am getting the following error. Please help me fixing this error.

I am using Oracle 12 c.

Hi, folks!

Is there any way to use $CASE or $SELECT functionality in SQL SELECT query?

E.g. something like this:

SELECT product, $CASE(status,"New":field1,"Payed":field2) as data from sales

To see either in data column either field1 or field2 values in regard of status value.

Hi-

I am running the latest version of Cache and am trying to use the Config.* classes in the %SYS namespace to be able to gather information from a cache.cpf file that was provided to me by a customer.  The customer is running an older version of Cache which had a different Version number in the cpf file.  Theirs is 2013.1 and mine is 2015.1.  

My question is, are the Config.* classes backwards compatible.  Can I use a 2017.1 version of Cache to read information from cpf file from a 2014 system?

Hi all-

We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports.  We want this applet so that the user won't have to open each PDF in the browser just to print it.

But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down.  We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page.  I am new to Cache so any help would be greatly appreciated.

Also, is there an easier solution to this print all problem?

Hello,

I am looking for ObjectScript implementation of crypt-compatible function, that generates md5 salted hashes (output is in the form of $1$salt$hash). From what I understand it uses its own spin on md5 algorithm:

https://en.wikipedia.org/wiki/Crypt_(C)
http://php.net/manual/en/function.crypt.php
http://www.gnu.org/software/libc/manual/html_node/crypt.html

Does Cache have something like that built in?

Has somebody here seen it implemented somewhere?

Thanks.

Added:

I have found description of the underlying algorithm here: https://www.vidarholen.net/contents/blog/?p=32

If you are facing out the license expire warning message on your terminal ("*** Warning: This Cache license will expire in 3 days ***") and you do not want that message to be displayed, you can disable/enable that by rinning the following commands:

Do ExpirationMessageOff^%SYS.LICENSE - Disable

Do ExpirationMessageOn^%SYS.LICENSE - Enable

Hi , i have a JSON record as follow {value1,value2, value3}

I need to create a standards document for new developers who are coming to Cache from other backgrounds.

Does anyone have an in-house document they could share with me?

Hi, Community!

Consider I have ResourceA which is used by role RoleA in dev environment and want to deploy it with the solution on a target system.

Would you please share the best practices to make it?

Thank you in advance!

Hello again and welcome to the Part 3 - Using the SQL API!
If you have been wondering about how to use SQL along with Frontier, you came to the right place. That's because since Frontier wraps the common Caché SQL API within it's own, you need to use the API provided from it. But you don't need  to worry about its learning curve, because the Frontier SQL API is really simple.
If you arrived here without checking the Part 1, I'd recommend you doing so, because Part 1 covers the essential for getting started with Frontier routers.

1. Core concepts
   • Getting started
   • Creating a simple request
   • Quer

The definitions of these two compiler keywords looks very similar to me.

Is there any difference between these two keywords ?

When I declare a parent class as Abstract, its child class could be compiled successfully.

However, when I  declare a parent class as NoExtent, some compile errors about storage references get pop up for its child classes.

Thanks.

I have a class name stored as %String,

How could I get the names of all its child classes?

Thanks you.

I have a Powershell script to backup up a Cache database. The script runs through and backs up the database  with the normal 4 iterations. The script successfully produces the backup file and an associated log file. However, after completion of the backup there is what appears to be a permission error. I have not been able to find any information that would help me determine if this message impacts the integrity of the back up. From the end of the output of the backup:

Global references are enabled.Backup complete.

Hi, I work on my application and I  want to develop rules for extracting values from my database but i've any idea:

I want to order my records by the most recent timestamps values with profile_id and biometric type as keys, after comparing them with my personal program date (when the timestamp > at my fixed date : an alert message is sent to the patient)

you find here the attached screenshots for my to databases. thank's

Hi guys!

Unique, PrimaryKey and IDKey?
In what contexts does it apply?

IDKey sets the registry key access to the store.
PrimaryKey, Unique, and IDKey define the uniqueness in the records, but what is correct?

I use everyone? What is the context of each?

Hi world ,

when i apply this command :

Hi world,

Hi , World

this is i field in my global:

{"profile_id":"9XOzzcI8NfSUjxAhEt0cTLRejwmp6HPi","biometrics":[{"timestamp":"2017-05-17T13:45:40","utc_offset":"+02:00","resting_heartrate":120.0,"spo2":98.0,"activity_id":"591c540aac8f295479ee14ce"}]}

for information: it's respective key is "peyload"

my question is :

I want to extract the timestamps value , and the profile_id value , how can i do?

thank's

I've mentioned the QEWD project in this group before: it's a Node.js-based platform for web, Native and REST applications which tightly integrates with Cache.  It uses a somewhat different philosophy to the use of Node.js than the norm, and I've now published an article that explains this approach and the unique benefits that arise as a result.

It turns out that, integrated via QEWD, Cache is an ideal bed-fellow for Node.js.  QEWD makes the integration of Cache and Node.js exceptionally fast, simple and intuitive to use, but also extremely powerful.

I have a tablepane which uses Sql to get his data:

As you look at the ''Business" column i have to type a number (key Value) to get the [Fashion Retail] value.

How do I have to modify the Built WHERE clause in order to filter on name /description of  the Join Fields instead of the key value? I would like to filter on name/description rather than a key value. Some sample code is appreciated! Thanks in advance.

Dear Developer Community!

My name is Maks.

I developed DeclarativeCOS framework for declarative programming on COS.

Today I want to ask you about New Programming Language.

I have an idea to create new programming language which could be translated to COS classes / routines or even to int-files.

So, lets suppose it is happened. What do you want to see in such language?

Please feel free to say your minds. It is open discussion.

Hy.

Has anyone try to setup Cache DB in Docker Container?

Currently, we are utilizing batch jobs at the OS level to kick off routines that watch for files. We are trying to convert these processes to be performed by the Task Manager.

The routines have while loops and perform while loops so long as the time parameters are being met.

What's the best way to ensure Task Manager kicks them off after the completion of the shutdown/backup/start process is performed, which we do nightly? I want to ensure that it starts it regardless of the time that we've set.

Hoping someone can help.

I need to convert a timestamp from the following format (YYYYMMDDhhmmss e.g. 20160105125915) to UTC time in the same format.

I presume I need to convert it to the system format ( like $HOROLOG ) and then use something like ConvertTimeStampToHorolog or perhaps LocalWithZTIMEZONEtoUTC but not sure of the syntax.

Thanks,

Conor

Hello everybody,
we would like to be able to analyze a rather complex software application, which has been programmed in “M” for a number of years by different developers, by means of a tool.
Our goal is to find a starting point for a code refactoring process. In the long run we would like to gradually eliminate the code growth points.
Does anyone know of a tool that can help us to do this?
So far, we have only found "RE / m" etc. by George James Software, but we do not yet know if these tools will help.

Your support and suggestions will be greatly appreciated. Thanks.
