#ObjectScript

Hello,

I need to create a util function that loops thru every character in the data, execute a $ASCII() against it. If it falls outside the realm of extended ASCII we toss it.

the function should receive a string, execute a for...loop across it's length and use $ASCII to evaluate the character. Also the function should return an output argument that indicates if the string is UTF8 valid or not.

could anyone help me with this?

I am getting the date 20201121090000 in the HL7 message, How do I convert it to 2020-11-21 09:00:00 in a easy way?

I am currently doing it by extracting the first 7 values and splitting as date and time and then adding a hyphen using substring.

Is there an easier way by using $ZDATE? or something like that?

Hi,

I'm trying to access the categories configuration for the WorkMgr via COS, so I can be able to create new categories for our processes and this way try to overlock the limit of cores*2 workers. I've seen that last version of IRIS is supposed to have a menu on the portal (System Administration > Configuration > System Configuration > WQM Categories), but since we are in 2020.1 this doesn't exist.

Does anyone have experience with WQM.API to manage the categories, or the usage of ^%SYS("WQM") to set it directly?

Hello all,

Hi,

InterSystems IRIS has long supported the obvious translation functions required to for converting to upper or lowercase to enforce case-insensitive string comparison (e.g. in ObjectScript with $zconvert) and sorting (e.g. with SQL collation functions, not to be confused with NLS collation). Customers in international contexts have at times used custom workarounds to also treat accent insensitivity or even more advanced normalization duct tape. We’re looking to address such use cases at the system and SQL level to increase convenience for this international audience, which is well represented on the Developer Community.

Hi Community,

Please welcome the new video recorded by @Evgeny Shvarov on InterSystems Developers YouTube:

Class Queries in InterSystems IRIS (and Cache, Ensemble, HealthShare) is a useful tool that separates SQL queries from Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name. This approach is also convenient for custom queries, in which the task of obtaining the next row is defined by a developer. Sounds interesting? Then read on!

$LIST string format and %DynamicArray and %DynamicObject classes

IRIS, and previously Cache, contain several different ways to create a sequence containing a mixture of data values. A data sequence that has been available for many years is the $LIST string. Another more recent data sequence is the %DynamicArray class, which along with the %DynamicObject class, is part of the IRIS support for JSON string representation. These two sequences involve very different tradeoffs.

$LIST String Format

– I want to “copy” a file to another, appending if the file already exists. The below code works, except it overwrites the new file, rather than append. The documentation says CopyFile will append

We released a new version of ZPM, with a set of great enhancements:

• $zpm function
• new arguments for search command
• and more!

See the details below

Hi developers!

Want to discuss with you the case of %Status.

If you familiar with ObjectScript you know what is it. I'd love to hear the history of the case why it had appeared in ObjectScript but it turned out that almost every system/library classmethods return %Status and there is a whole set of tools to deal with it.

What is does it gives you the responsibility to check the value or %Status of every system method you call.

E.g. if you save the data of the persistent class, you should never call like this:

do obj.%Save()

you need to call:

set sc=obj.%Save()

if $$$ISERR(sc) do // something or quit.

I want to call some Java Remote Call through Java gateway. The call code as following:

class CallRemote Extends %CSP.REST {

Method Index() as %Status {

Try

set gw = createJavaGateway()

Do callJavaMethod(gw)

do gw.%Disconnect()

Catch {

}

}

}

But Every call need connect to Java Gateway and disconnect it. But It's cost too high( about 80ms)

So, According to my Java experences, I need create some connection and put it into global static ConnectionPool

Hi,
I'm looking for a way to run ZPM (especially install) in a total silent mode with no output.

I tried -quiet flag but it continues to chat to me like my wife.

The demo is based on the raw class descriptions.
The data classes used are Address, Person, Employee, Company
For a more attractive demo, a JSONtoString method by ID was added.
