Every row-and-column intersection contains exactly one value from the applicable domain (and nothing else).
The same value can be atomic or non-atomic depending on the purpose of this value. For example, “4286” can be
atomic, if its denotes “a credit card’s PIN code” (if it’s broken down or reshuffled, it is of no use any longer)
non-atomic, if it’s just a “sequence of numbers” (the value still makes sense if broken down into several parts or reshuffled)
This article explores the standard methods of increasing the performance of SQL queries involving the following types of fields: string, date, simple list (in the $LB format), "list of <...>" and "array of <...>".
I'm currently exploring alternatives to CSP/services and ODBC/Sql Maps for access to Caché. I'm not seeing a library which would interest me, so am considering creating one myself.
Does 'CacheConnection' in C# use RPC of some sort, or a defined protocol to communicate with Caché, or does it do so over telnet with scripted commands? I would assume the former. If so, is this a publicly documented protocol that can be implemented by library developers?

I needed to pass through a file with Ensemble but the operation wasn't writing some filenames as given because the EnsLib.File.PassthroughOperation 'sanitizes' filenames removing characters that are not valid on some operating systems; 09000655_AEDC_C3344059_A/E_Martin Browne_09000655_201706221018.pdf 09000655_AEDC_C3344059_A#47E_Martin_Browne_09000655_201706221018.pdf
Has anyone worked out any tricks to overcome this issue in 2015 and IE11 where the Dialog content is masked. I'm trying to fix it in a custom one, but you can see that the same issue is happening in the Standard Color Selection one as well.
Good day, I have this issue. I have global like: ^myglobal(varX) = $LB(var1,var2). I need to delete all globals that have variable var1 in that list same without a need to iterate through all globals and checking their value.
Good day, I would like to find out the size of Caché ObjectScript variable in order to guarantee that my program will not leak, equally in terminal and Caché globals. For example how huge number I can store in that variable ? And what happen in Caché when variable will leak ? How is this behavior treated? (how much memory is reserved for common variable?)
In my cache studio i couldn't find the a namespace of iknow so how can i check is my studio version is compatible to to the one i am using now. If i don't have one then can be able to create a new namespace in studio?
I'm studying AngularJS now ( looking for a substitute for my zen-mojo application ) , I would like to understand how can I connect from the client (AngularJS) with the server , passing data & invoking methods server side.
I have created a class that extends file operation, but can't find the object that has the value for the file path. Is that object in pRequest or is there an another object I should be used to see that value?

We have many severs (DEV, QA and LIVE) besides many other slave servers (about 133) that are running Caché instances. Before writing this utility myself, I would like to know if anyone has done it before. We need to change the SuperUser password and do other credential setups like this on all of these servers and we don't want to do it one by one.
I would like to start a discussion regarding Caché Objects and Caché SQL.
It is my understanding that the creators of Caché Objects see Caché SQL as the reporting arm of Objects and as such SQL is essential to Caché Objects.
I once met a Caché Objects programmer who was writing code to $Order through the Globals because that person thought that Caché SQL was too slow and inefficient. I attempted to convince the person otherwise.
So, what say you? Is SQL essential to Caché Objects?
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
