Hi folks!

Sometimes we need to import data into InterSystems IRIS from CSV. It can be done e.g. via csvgen tool that generates a class and imports all the data into it.

But what if you already have your own class and want to import data from CSV into your existing table?

There are numerous ways to do that but you can use csvgen (or csvgen-ui) again! I prepared and and example and happy to share. Here we go!

%Status usage in ObjectScript

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.

So I have an interesting problem. I am going to be using a process and rule to determine if an HL7 message qualifies to be sent out, then using a record map to write certain aspects of that HL7 message to disk (with an HL7 to record map DTL). This is simple enough but the recipient of this file is requiring a single record map entry per DG1 segment in the HL7 message.

For instance if said HL7 message for PATIENT^TEST has 3 DG1 segments, I would need to write three lines (or records) like so:

123^^^^MR|TEST|PATIENT|DG1(1) TEXT|DG1(1) CODE|DG1(1) DATE

Send an HTML Email

This code snippet contains the class method "test" which sends an HTML email. Change the literal strings in the method to customize the email's from address, to address, subject, and body:


Class objectscript.sendEmail Extends %RegisteredObject
{
    classmethod test() {
        set m=##class(%Net.MailMessage).%New()
        set m.From="user@company.com"
         
        set m.IsHTML=1
         
        do m.To.Insert("user@company.com")
        set m.Subject="Sent by IRIS mail"
        set m.Charset="iso-8859-1"
        do m.TextData.Write("<HTML><HEAD><TITLE></TITLE>"_$char(13,10))
        do m.TextData.Write("<META http-equiv=Content-Type content=""text/html; charset=iso-8859-2""></HEAD>"_$char(13,10))
        do m.TextData.Write("<BODY><FONT face=Arial size=2>Test <B>Test</B></FONT></BODY></HTML>")
        set s=##class(%Net.SMTP).%New()
        set s.smtpserver="mail.company.com"
        set status=s.Send(m)
    }
}

Hi!

We need to use a bash script under Linux in order to export a namespace's clases (*.cls), project (*.prj), *.inc and all related stuff (except generated and mapped clases). All these elements must be stored on a XML file.

We need to use a bash script under Linux to import and compile previously exported XML file (from Studio, Management Portal, or Export Script) .

Can anyone help us to develop them?
Thanks in advance!

I have posted to aid others in diagnosing problem with SSL/TLS connections to superserver port from .NET client executable.

The cache instance this appeared on is quite old - 2011 - so I do not know if Intersystems have added a better error message in a later version

The actual fault was due to the certificate in the %SuperServer SSL/TLS configuration having expired.

The unhelpful message that appeared in the .NET client included the following partial stack trace.

Hello All,

I hope it's not a silly question.

Here is my issue:
I have 3 simple classes:

Parent class, let's say:

Class ParentClass Extends %RegisteredObject
{
Property a As %String;
}

and two children classes
Class A.Child Extends ParentClass
{
Property b As %String;
}

Class B.Child Extends ParentClass
{
Property c As %String;
}

So no issues - all compiles and seem to work.

But, when I add %XML.Adaptor to my parent class, so:

Hi all,

I am new in Cache. I have to update a record with a long text field, for that, I am using ODBC but the issue is that it is returning an error when I execute the ODBC SQL statement because the field contains some commas, colon, double quotes, single quotes, and CR LF characters.

There is a way to escape this chars? I have seen I can save the field when I replace the single quotes with a double single quote (it's -> it''s) but I can not save the information when the field contains double quote chars. What about the other chars?

Hi,

I am very much a newbe on the subject of JWT, so please except my ignorance.

The Trust I am currently working for wish to create a framework whereby they can create REST API Services, within HealthConnect, and grant access to these using JSON Web Token Authorisation and Bearer Tokens. This would be similar to the way the Trust currently connects to other REST API's, i.e.: DocMan Connect and GOV.UK Notify.

Can anyone offer any advice / sample code and / or point me into the direct of suitable documentation to achieve this?

Hi, I am trying to transform a message to meet a third party specification, and would like to know if you can advice me on how to separate a single OBX segment into several segments based on a '.'

I would like to separate the segment where the . [marked in red] is into another OBX segment. So the next segment would be:

Who does Windows think I am?

When my COS code is executing in a Caché process it might want to interact with the host operating system. For the purpose of this post I'm focusing on a Windows host, but much of it applies to other host OS platforms as well.

A common example of host OS interaction is when my process wants to read from or write to a file. What credentials will apply when Windows is checking whether or not to allow me access to the file?

To answer that we need to consider another question. How did our process start?

I know %CSP.Daemon is supposed to clean up old CSP sessions (?). In my management portal, under System/ License Usage, I see 33 "Units" used (and there are 33 licenses in use), but usernames from old IP address and that are not being used. Their active times are often in the millions of seconds. They are not "on" the system right now.

At most, only 3 users are on the system right now.

Are these supposed to be cleaned up? Can I clean them up programmactially, and how would I know if they're not active?

Thanks,

Laura

Intersystem jar files

I'm working on developing Productions with java. The sample project has several intersystems jar files:
-- intersystems-enslib-jms-3.1.0.jar
-- intersystems-gateway-3.1.0.jar
-- intersystems-jdbc-3.1.0.jar
-- intersystems-spark-1.0.0.jar
-- intersystems-uima-1.0.0.jar
-- intersystems-utils-3.1.0.jar
-- intersystems-xep-3.1.0.jar

I have the jar files, but where can I find them for download? Are they available on a maven repository somewhere?

Any help would be appreciated!

I like to know if COS has a PGP library for encryption and decryption messages received from an SFTP connection. We have interfaces that we used BouncyCastle in C# but would like a native library for COS.

I'm using Cache SQL and want the ability to choose a specific index.

I've boiled the problem down to one table and simplified the query down to

SELECT *
FROM Registration.PatResp
WHERE SchedApptNum=8450022

SchedApptNum is indexed, but instead of using that column, "Show Plan" indicates that it's looping through the entire Registration.PatResp table on Id (the primary key for the table).

I've done a tune-table with no change.

Hi Community!

I have very good news for the developers, who are using GitHub to host projects with InterSystems ObjectScript. GitHub introduced the support of InterSystems ObjectScript this week!

How does it work?

Now all the .cls files in your repository are considered as InterSystems ObjectScript and highlighted according to the language rules of ObjectScript. For example WebTerminal, Samples-Data.
