PHP, from the beginning of its time, is renowned (and criticized) for supporting integration with a lot of libraries, as well as with almost all the DB existing on the market. However, for some mysterious reasons, it did not support hierarchical databases on the globals.

Globals are structures for storing hierarchical information. They are somewhat similar to key-value database with the only difference being that the key can be multi-level:

Hi all,

I am trying to delete an item from a production through a routine that installs and disables items.

To add any item, I have no problems, even to enable and disable some particular items.

The problem arises when I try to eliminate the production item, because when it does, the production become unstable and only works again when this item is added again in the collection (or the item is deleted manually in the production.cls)

This is my code attempt:

In the previous parts (1, 2) we talked about globals as trees. In this article, we will look at them as sparse arrays.

A sparse array - is a type of array where most values assume an identical value.

In practice, you will often see sparse arrays so huge that there is no point in occupying memory with identical elements. Therefore, it makes sense to organize sparse arrays in such a way that memory is not wasted on storing duplicate values.

In some programming languages, sparse arrays are part of the language - for example, in J, MATLAB. In other languages, there are special libraries that let you use them. For C++, those would be Eigen and the like.

Globals are good candidates for implementing sparse arrays for the following reasons:

I need to create a healthcare management software for a local blood bank whose branches are spread throughout the USA. The Client has set the condition to use inter systems as the database management.

I am looking to create the app using PHP language and then host it through with VPN so that they all are interconnected. But due to the raise in cyber attacks. The client is seriously concerned about the security of the app thus wants to host it on google dedicated server which is being powered by cloudways.com/en/managed-google-compute-engine.php.

HL7 HTTP Response Charset

Hello,

currently we have a problem in development with the character set of the response message.

We are transmitting an HL7 message with an operation based on the EnsLib.HL7.Operation.HTTPOperation class.
We have changed this as follows.

Set pMsgIn=$$$NULLOREF, tHttpRequest=##class(%Net.HttpRequest).%New(), tHttpRequest.WriteRawMode=1, tHttpRequest.ContentType="APPLICATION/HL7-V2; charset=UTF-8"

Unfortunately, the ContentType character set is not read correctly in the response.

In our table, we have a column cities, which has a filter which displays the cities of a state depending on the state

For simplicity let's assume we have a page

Property State As %String = "CA"

Our filter should run this query to show all cities of state ca

Hi,

Most of my development experience is with HL7v2 interfaces and I don't have a background in web development and I'm very weak with javascript.

I'm looking for suggestions of learning resources to learn FHIR and 'SMART on FHIR' (JavaScript, OpenID connect, OAuth2) for developers like myself who mostly do HL7v2 integrations - but see FHIR as the future - and want to develop their skills!

I've found these

Hi All,

I have two tables LB_TestSet and LB_Transfer

LB_Transfer has a list if TestSet row IDs, so i am doing the following join

SELECT 
LBTS_RowID,
,LBTS_CollectedDate
FROM SQLUser.LB_TestSet 
JOIN SQLUser.LB_Transfer ON ($LISTBUILD(LBTS_RowID) %INLIST LBTR_TestSetList)
WHERE LBTS_CollectedDate BETWEEN '2019-01-01' AND  '2019-05-10'

Without the date filter the query returns data, but if i add the date filter no data is returned

I also tried using %INTERNAL, %EXTERNAL TO_DATE('2009-01-01','YYYY-MM-DD')

Hi All,

Just wondering if anyone had got this working.

In the documentation it says to set the username and password properties of the connection object but these properties don't exist and without authentication I can't connect to the MQ queue.

Any help would be greatly appreciated,

The last time that I created a playground for experimenting with machine learning using Apache Spark and an InterSystems data platform, see Machine Learning with Spark and Caché, I installed and configured everything directly on my laptop: Caché, Python, Apache Spark, Java, some Hadoop libraries, to name a few. It required some effort, but eventually it worked.
