#ObjectScript

This applies to embedded and dynamic SQL queries in Caché ObjectScript. If I attempt to terminate the process via Management Portal, nothing happens. Neither does Ctrl C nor closing the terminal window in which my program is running, nor setting a stop flag in a global which is read by the program on each loop iteration. The only way to stop the query appears to be restarting the Caché server (which is running locally on my PC).

I am making a POST request to an API. In the case of an error, I don't know what parameters the response JSON will contain (they will change depending on the error). I am converting the response stream to an object but then I need a way to loop through all the properties and access their values. The following code is making the POST request, reading the response, and trying to add all the error messages to an array. But I can't iterate over the properties of the tProxy.errors object because it is a %ZEN.proxyObject. Is there a better way to do this?

Hello community,

I want to iterate through a defined collection/list of numbers for example 1,3,4,5 in my DTL.

Something like

It's a feature of ObjectScript (perhaps widely known, perhaps not) that if you open the same object ID multiple times, you end up with the same OREF. For example:

USER>set obj1 = ##class(Sample.Person).%OpenId(1)
 
USER>set obj2 = ##class(Sample.Person).%OpenId(1)

USER>w obj1,!,obj2
1@Sample.Person
1@Sample.Person

Generally speaking, this is an important feature - you won't end up accidentally modifying the same record via multiple paths and losing some of the changes.

In the sample below, an image file is encoded into a Base64 string in a class property, saved, decoded again with Base64, and restored to another file.

【Usage class】

Class User.test Extends %Persistent
{
Property pics As %GlobalBinaryStream;
}

【When importing】

Hi All,

is there any way how to hide or remove storage "Histogram" section in the file with persistent class definition, but keep the data both in globals and sql table?
The reason is that we use on-premise version control system and since the data is sensitive, it cannot be uploaded along with the files.

The related package avoids adding %JSONAdaptor to each class but uses instead
SQL functions JSON_OBJECT() to create my JSON objects. With this approach, you can
add JSON to any class - even deployed ones - without any need for change or recompiling.

The trigger was the Export of M:N relationships as JSON objects or arrays.

Currently I have a program that is going to be used to compare global nodes between namespaces. Using nested FOR statements I am stepping through global nodes and comparing between the namespaces, if the global values are different I then parse the node comparing each delimited segment.

This is working.

I want to now be able to set what global I am in as a variable to expand on this concept.

Program architecture

Hi,

I want to write a class to write a customized SSL/TLS certificate expiry alerts using ObjectScript?

Any sample code for reference available?

Thanks,

Is it possible to "Ping" a remote host in IRIS for Health using ObjectScript? We host hundreds of TCP connections over hundreds of VPNs. I'm working on a project that would make it nice to have way to ping remove clients over the VPN to monitor connectivity and keep the tunnels alive.

Another thought/method would be to make an OS system call (AWS Linux), but I don't see a way to do that either.

Hello,
as i'm trying to develop a operation and its methods (SQL adapter), I'm running into issues when i run my test class.
I have the class i want to test in the very same folder as my test class.
I followed the tutorial in the documentation.
When i run the test class, i get the following message error :

LogStateStatus:0::ERREUR #5002: Erreur Cache: <METHOD DOES NOT EXIST>zTestAdd+1^unitTests.testMyClass.1 *myMethod,Package.BO.MyClass

Here is my test class (heavily inspired bythe documentation :-) :

on red hat, but I would also be interested in a wider answer.

after running a benchmark for 40 minutes, I have been asked if any rollbacks occurred in that time. Rollbacks from SQL or objects.

The application does not record this, so I am looking for a system level record.

The journal entries do the necessary reverse sets and commit just like any transaction. So i don't think i can detect them there.

Hi there,

I want to use regex in my code, and I saw that the %Regex.Matcher class contains a property "OperationLimit" that you can also set to a number of steps that the regex engine should take maximum in analysing a given string. So far so good.

I tried to set the property with the function OperationLimitSet() to a silly value like 3. In 3 steps only very few regex should be executed, right? But what I found is that my regex always comes up with a solution. Here is what I did:

First I initialised my %Regex.Matcher.

Hi !

I'm looking for a simple way to store in a string a list in $lb representation. Ex :

Set list = $ListBuild("data2", "data2", "data3")
ZWrite list
/* show : list=$lb("data1","data2","data3") */

With the ZWrite command, we can display the $lb representation but I would like to store it in a string variable.
