Hello community,

I would like to know answer to the question: What would be an optimal way to connect an Ensemble and a pure Caché server? Optimally in such a way for the Caché system to be able to fire Ensemble processes and the Ensemble server to call Caché server functions.

Is there a way to use a HL7 field value as part of the File Naming in the Business Operation FileOperation class. I know we can do this in a custom class, but I was wondering if it could be done the default FileOperation class?


MSH-4 contains the value 12345

We would like to name the file 12345_YYYYMMDDHHMMSS.HL7

MSH.4 value here_%Y%m%d%H%M%S.HL7

It may not be possible, but I just want to see if anyone has any information

Hash values of columns

I try to find a function, which generates hash values of columns. In MS SQL Server I can use

select hashbytes('sha2_256', my_column) ...

to create hash values of my_column. Is it possible to use such things in Caché?

Thank you

Let's say I open a stream/file.

If it's not in UTF8 i need to call $ZCVT, and if it's already in UTF8, then I don't need to call $ZCVT.

Is there any way to determine character encoding for input stream/file?

Recently I was conducting a remote support session with a site. The desktop they were sharing with me was on a PC configured with German as the native language. Since my German is rather rusty, and virtually non-existent when it comes to computing terms, I was glad to be able to switch the Portal session into English.

This is done from the page that appears when you use the About link:

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


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


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, Community!

How do you store the source files of your Caché project? What is the directories structure? What are the benefits?

I prefer the following structure:








  • folders are packages.
  • easy to understand what type of sources are in the project.

What is your approach?

I have Caché/HealthShare installed in a local Ubuntu 16.04 LTS virtual machine. I've also installed Apache 2.4 from the apache2 bundle, and enabled SSL. I've configured Caché such that SSL/TLS is enabled on the SuperServer port but not required.

I want to attach one local namespace on instance A to the database on instance B.

How could I use ECP to achieve my goal?

Should I config instance B as ECP data server? If so, how could I explicitly specify which database on instance B could be exposed ?

Thanks for your help.

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!

In Cache Studio there is export class dialog with options "Export current project" and "Include dependent classes".

Is there any way to export class programmatically, but with same effect as if "Include dependent classes" was checked? So that not only the class itself is exported, but also all dependent classes? I know of Export method in %SYSTEM.Obj class, but it only exports the class itself.

SQL Query for Range


I have a question related to running an SQL query for range of data.

I am running a query like:

Select A,B from table_name where A>=12345 AND A<=12390

- Where A and B are my two of the properties under the mentioned table/class definition

- A is an integer property

Question: The result of the above query does not return me all the values between the mentioned range of integer though I do have all the values in that range. I see that some of the values are missing in result.
