Hello Gentlemen,

As you can read on the title, my question is to know how to retranslate the hl7 message into a string and so to remove the '\E' that are inside. A example/picture worth more than a thousand word.

OBX|1|RP|ECG||CARDIO ECG^APPLICATION^PDF^^\E\\E\sitehopital.org\E\files\E\cardio\E\022018\E\GE274583.PDF|

I am trying to read some binary data from a local file or through socket.

The binary data is like H.264 codec, I need to read data BYTE by BYTE (even BIT by BIT) and decide the next step based on the data read so far.

I check the documentation and it seems like most of the sample focus on human readable IO, ie: LINE by LINE.

Could I achieve my goal through COS?

Thanks.

We have a couple of systems that send us a URL link to a PDF instead of base 64 encoding it in the HL7 message. Has anyone ever tired to take that URL, and retrieve the file off of the server to save it off somewhere?

Say you have a global in one database that you instead want to map from a different database. If you just create a global mapping to the new database, the existing global will become inaccessible because it still lives on the old database. The documentation notes this problem here but doesn't give details on how to fix it.

Hi Developers!

Sometimes we need to import CSV data programmatically to InterSystems IRIS either from CSV or from URL. And we expect the class with proper datatypes to be created and the data to be imported.

I published a module csvgen on Open Exchange which does exactly that.

If you just need the CSV file be imported into IRIS you can do the following:

USER>do ##class(community.csvgen).Generate("/usr/data/titanic.csv",,"Data.Titanic")

Class name: Data.Titanic
Header: PassengerId INTEGER,Survived INTEGER,Pclass INTEGER,Name VARCHAR(250),Sex VARCHAR(250),Age INTEGER,SibSp INTEGER,Parch INTEGER,Ticket VARCHAR(250),Fare MONEY,Cabin VARCHAR(250),Embarked VARCHAR(250)
Records imported: 891
USER>

Or if you have the CSV on the internet, e.g. COVID-19 Data on Github you can get the data in the following way:

USER>d ##class(community.csvgen).GenerateFromURL("https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_daily_reports/05-29-2020.csv",",","Data.Covid19")

Class name: Data.Covid19
Header: FIPS INTEGER,Admin2 VARCHAR(250),Province_State VARCHAR(250),Country_Region VARCHAR(250),Last_Update DATE,Lat MONEY,Long_ DOUBLE,Confirmed INTEGER,Deaths INTEGER,Recovered INTEGER,Active INTEGER,Combined_Key VARCHAR(250),Incidence_Rate DOUBLE,Case-Fatality_Ratio DOUBLE
Records imported: 3522
USER>

I'm trying to learn how To use SQL in CACHE, so I hope I don't bore you with "Dumb" questions....

I'm getting "ERROR #6022: Gateway failed" message following this line of code.

s sc=gc.Prepare(hstmt,pQuery) 

This line of code comes from an example I found in the documentation. pQuery is the "Select" statement setting up the variables and tables I'm trying to pull information from.

What does that error indicate?

Thank you.

Over the years, I have found myself needing to create multiple HL7 messages based on a single inbound message. Usually these take the form of an order or result from a lab. Each time I have approached it, I have tried to start from scratch under the belief that the previous attempt could have been done better.

Hi,

Thanks for your time.

Plain $ZF(-1) and $ZF(-2) calls from Cache Studio or Terminal have stopped launching the OS shell from Win10.

cmd (Windows Command Prompt) should be launched.

Configuration:

Windows 10 Anniversary Update, Ensemble 2016.2.0.585.0 Developer Edition x64

Is this common? I have enabled both %Developer role and a Cache CallOut privilege for all users that operate in this scenario.

In Terminal, W $ZF(-1) prints -1, W $ZF(-2) prints -1

In Studio, W $ZF(-1) hangs the IDE, W $ZF(-2) prints 0

I face the challenge to have a bunch of classes on IRIS and CACHÉ in parallel
until all systems are migrated to IRIS.

Applying changes in Caché development environment and moving to IRIS is no problem

But if I have to apply a fix on IRIS there seems to be no clean way back to Caché.

I have the following problem:

• There are several classes with method generators, which needs to be compiled during every compilation
• I have "ckub" qualifiers enabled in studio
• I don't want to remove "u" qualifier because I need it very much in another namespaces

So how do I force classes with method generators to recompile when "u" qualifier is present?

I am using java gateway imported/proxy classes and JG business service. I need to load a dll at run time.

I use System.loadLibrary/System.load when in java. I’ve tried $ZF(-3,” C:\Windows\System32\pteidlibj.dll”) and $ZF(-4,1,"C:\Windows\System32\pteidlibj.dll") but I’m getting <DYNAMIC LIBRARY LOAD> error.

How can I load a dll at run time using COS?

Hi, Community!

Last weekend we held the Final of InterSystems Contest on Caché, DeepSee and iKnow under the aegis of IT Planet Student Championship in Ekaterinburg. BTW, this year we had more than 1,400 participants in InterSystems Contest.

Hi,

I got the <INVALID OREF> error in the component and the error screenshot as follows:
