#ObjectScript

InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.

Hello guys,

I've got this piece of code which runs the method "WebMethod", that belongs to %SOAP.WebBase.cls.

It grabs the outcome from an internal webservice we have and after that, it writes into a file.

The thing is, when I browse the file contents, I realize that in the place where a special character should be, I see a question mark.

By querying the same webservice from a special soap tool called "SoapSonar" (I've been using this for years), the outcome shows up this special character (shows it properly).

Hello, we have a few hundreds of triggers to port from Oracle to Cachè for a migration project, and many of them have to change (for example, normalize a value, null it, etc) the value which is being inserted.

The documentation says "You cannot set {fieldname*N} in trigger code." , so we're unlucky.

Is there a good workaround for this ?

SqlComputeOnChange doesn't seem the best way, but I'm not totally sure: for example normalization and validation could have a better place somewhere else than a trigger.

Has anyone tried adding syntax highlighting to GitHub for Caché CLS files?

Looking at the list of supported languages and extensions...

https://github.com/github/linguist/blob/master/lib/linguist/languages.yml

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...

This is a series of programming challenges for beginners and experienced Caché programmers.

You walk into a room, step on a tile and hear a loud click...

Traps !

The challenge is about avoiding traps.

You can recognise if a tile is a trap by following scheme :

Hi,

My doubt is about the SQL Query in Caché:

I don't want to take all results from the table and orgainze them manually, for example: I have a table with 50 records, but I only want to select 10 records, being from tenth until the twentieth and this without knowing their IDs.

So, how can I do this, without losing performance, there is any way?

Hi!

Consider I have a class Package.Data with Property UniqueStringValue as %String.

I introduced the Index for this property:

 Index ValueIndex on UniqueStringValue [Unique];

It works well. But if I try to check if there is an object with the certain value in code like this:

if ##class(Package.Data).ValueIndexExists(value)

this expression fails, if value="value", even if there is an instance with instance.UniqueStingValue="Value"

How can I set the index to prevent saving case sensitive values in this class?

I have classes A and B, B derived from A, A has method Abc.

From INT of class B I see that compiler copies implementation of Abc to class B, so that Abc exists both in A and B.

As result, when B invokes Abs, B.Abs() is executed instead of A.Abs(). In result debuger is not able to step into Abs and breakpoints in A.Abs never hit.

Why this happens and how can I avoid this?

Update:

OK, now I know the reason: compiler makes the copy if Abc has this line:

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.

Good day,

I need to find out if it is possible somehow to receive actual linux TIMESTAMP for example with $NOW() or other functions.
I was trying to recalculate it with $NOW() function, but without success. I would like to simulate Redis TIME command in COS.

My tryings:

USER > set time = $NOW()

USER > w (($PIECE(time,",",1)*86399) + $PIECE(time,",",2))
5573319043.403186

But in Redis it is:

Hi everyone,

I'm having trouble parsing XML containing unicode characters which I receive from an external webservice. I believe my file is saved properly with UTF-8 encoding but the SAX Parser still throws me an error.

I have 2 classmethods: 1 general one (get) to make a request to a webservice and return the date, and 1 (getSportsPerDate) to make a specific call and then parse the data.

What is difference between using a command $classmethod rather than just invoking them straight away?

For example if i need to call a class and its method i can just use like

do ##class(circle).radius()

rather than using

do $classmethod("circle",radius)

(I suppose both of them doing the same function i am not aware of it)

Please help me understand what is different and is there any specific usage.

Correct me if i have made mistake.

Rebuild class index

I have a class. In class there is an index. This index is for quick search on name property.

Class User
{

.....

Property Name as %String;

Index NameInd On Name;

.....

}

This class is mapped to some global ^GL(userId) = "Name*other data....****"

And there is also index global ^GLNameIndex(Name, userId) = ""

When I add new User entry through class, f. i.

S user = ##class(User).%New()
S user.Name = "Some name"
​D user.%Save()

calling method %Save() adding new entry to index automatically.

With help from others here I had developed some code to take a Base64 PDF within a OBX.5 and save it locally to the file structure on the server.

I had to make a change to the code to return me a String so I can pass the Path back into Ensemble to use it in the message. When I made this change I am getting " ERROR #5034: Invalid status code structure ("/ensemble/data/transfer/AncillaryPDF/TMSAUDIO/Apr-11-1/980512729TMSAUDIO1046784936436537800.pdf")"

Here is the code...
