Hi Gregor,

First off all, try to connect to MySql directly by a shell command :

echo "select 1" | isql -v my-connector

Expected response :

+---------------------------------------+
| Connected!                            |
|                                       |
| sql-statement                         |
| help [tablename]                      |
| quit                                  |
|                                       |
+---------------------------------------+
SQL> select 1
+---------------------+
| 1                   |
+---------------------+
| 1                   |
+---------------------+
SQLRowCount returns 1
1 rows fetched

Where /etc/odbc.ini :

[my-connector]
Description           = MySQL connection to  database
Driver                = MySQL
Database              = example
Server                = localhost
User                  = example
Password              = example
Port                  = 3306
Socket                = /var/run/mysqld/mysqld.sock

and /etc/odbcinst.ini

[MySQL]
Description = ODBC for MySQL
Driver = /usr/local/lib/libmyodbc8a.so
Setup = /usr/local/lib/libmyodbc8w.so
FileUsage = 1

If you successfully connected to your mysql database, then you can use it in IRIS/Caché/Ensemble :

Here is an example with %SQLGatewayConnection

set gc=##class(%SQLGatewayConnection).%New()
set pDSN="my-connector"
set sc=gc.Connect(pDSN,"example","example")
set sc=gc.AllocateStatement(.hstmt) 
set pQuery= "select 1"
set sc=gc.Prepare(hstmt,pQuery)
set sc=gc.Execute(hstmt)
set sc=gc.Fetch(hstmt)
set sc=gc.GetData(hstmt, 1, 1, .val)
zw val
set sc=gc.CloseCursor(hstmt)
set sc=gc.Disconnect()

To go further check those links :

Or even better check this training, it's with an JDBC connector but most part is applicable has DSN will fit your odbc config.

Hi Rubén,

Another proposition on IRIS 2021.1+ can be this one with the use of the new window (OVER) function :

ClassMethod getPersonsPagWindow(iAge As %Integer, sortField As %String = 1, sortOrder As %String = 2, pageSize As %String = 20, pageIndex As %String = 1) As %DynamicObject
{
    set out = []
    set vFrom = ((pageIndex -1 ) * pageSize)+1
    set vTo = vFrom + (pageSize-1)

    set sql = "SELECT * "_
                "FROM ( SELECT persons.* "_
                "        , ROW_NUMBER() OVER (ORDER By "_sortField_" "_ $CASE(sortOrder,1:"ASC",2:"DESC",:"ASC")_
                "    ) rn "_
                "        FROM Sample.Person persons where Age > ? "_
                "    ) tmp "_
                "WHERE rn between "_vFrom_" and "_vTo_" "_
                "ORDER By "_sortField_" "_ $CASE(sortOrder,1:"ASC",2:"DESC",:"ASC")

    Set rs=##class(%ResultSet).%New("%DynamicQuery:SQL")
    set sc = rs.Prepare(sql)
    set sc = rs.Execute(iAge) If $$$ISERR(sc) Do DisplayError^%apiOBJ(sc) Quit

    while rs.%Next() {
        Do out.%Push({
                "pid": (rs.%Get("ID")),
                "ssn" : (rs.%Get("SSN")),
                "lastname" : (rs.%Get("LastName")) ,
                "givenname":    (rs.%Get("GivenName")),
                "secondaryname":       (rs.%Get("SecondaryName")) ,
                "gender": (rs.%Get("Gender")),
                "age": (rs.%Get("Age") )
                })
    }

    set outJson = []
    Do outJson.%Push({
                "pageSize":(pageSize),
                "pageIndex":(pageIndex),
                "fromIndex":(vFrom),
                "toIndex":(vTo),
                "resultSet":(out)
                })
    return outJson
}

I bench the two solutions on a dataset of 100 000 rows without index with a result of 20 elements on page 1 and here are the results :

"getPersonsPag timed : 1,647 secondes"
"getPersonsPagWindow timed : 0,247 secondes"

I guess that the window function is faster because you don't have to fetch all the data in a global before paging.

Hi Esther,

This link is working http://localhost:52775/csp/sys/UtilHome.csp?$NAMESPACE=IRISAPP

If you are not working with the docker version of this training, you may be need to adjust the port from 52775 to 52773 and adapt also the namespace.

Bravo for this initiative.

For your information, this is at least the 5th or 6th time that I return to this page to use this magic command :)

In addition to this trendy post, I propose to add this link to a training on github about the interoperability framework.

Guillaume Rongier · Oct 21, 2021 go to post

Where do you struggle ? Is it in the BPL, in the Operation or during the insert statement to SQL Server ?

If the bottleneck is in the insert statement check out this community SQL adapter (work only on JDBC). https://openexchange.intersystems.com/package/ETL-Interoperability-Adapter

This adapter provide you an access to insert batch statement, that can speed up the insert speed up to 10 times even 100 times.

In the github repository you have some example how to use it : https://github.com/grongierisc/BatchSqlOutboundAdapter/blob/master/src/CLS/Grongier/Example/SqlInsertOperation.cls

Guillaume Rongier · Oct 21, 2021 go to post

The difference between a stored procedure and SQL inserts is that the business logic remains on the application side and not on the database side to keep the principles (storage/logic/representation) separate.

Nevertheless, the problem doesn't seem to be at the SQL level but rather at the BPL level, so maybe it's due to the conversion of XML to object?
If it is the case, use different technique to parse the XML, like the SAX Parser which avoids to mount all the XML document in memory.

The king is dead, long live the king! is a traditional phrase that is proclaimed at the advent of a new monarch in France.

May I say: IRIS is dead, long live IRIS!

This is what I feel with the arrival of Embedded Python.

The old monarch spoke ObjectScript, he allowed us to accomplish great things but now let's stop looking back, let's move forward. Let's induct the new monarch who speaks Python. Let's stop worshipping his father and let's make room for the new generation.

That's why I think, we must stop coding in ObjectScript, we must strive to use Python, everywhere in IRIS and this without the wrapper ([language = python]).

Why be so radical?

Coding in Python is to show by example and in a language that the uninitiated know and thus prove the extent of the possibilities of IRIS
Coding in Python is to start answering and finding solutions to the new problems that we will encounter: a. How to integrate .py files in our CICD pipes b. How to integrate PyPI with ZPM c. How to elegantly expose future APIs coded on the Flash Framework with IRIS and CSP gateways
Coding in Python encourages InterSystems to produce new packages in Python rather than ObjectScript.

Choosing your programming language in IRIS is a political act.

Coding in ObjectScript is to be conservative.
Coding in Python is to be liberal.

Choose your side.

Guillaume Rongier · Nov 19, 2021 go to post

Yes, you can easily gain a factor from 5 to 10 in insert time.

I your case, you can expect your batch to be processed in less than 30 minutes or so.

Example of code can be found here :

https://github.com/grongierisc/BatchSqlOutboundAdapter/blob/master/src/…

BTW : This adaptor only works with JDBC drivers.

@Ben Spead

With Embedded Python, code can (and should?) not be stored in the databases and still be executed on the server side with the irispython interpreter.

Here is a GitHub link that demonstrates the use of embedded python with a backend on the Flask micro framework + Iris as a database.

It is true that Embedded python will change a lot of our paradigms, best practices, reflexes.

That's why we, as ObjectScript and IRIS experts, must try to use it as much as possible.

We will have to go out of our comfort zone and it is essential, it is up to us to go towards the python community because the opposite will not happen.

Regarding the [language = python] tag, I'm not saying it's useless. It can be useful in some cases. I just think that it should not become the norm.

PS: My previous answer is indeed provocative and this is to draw attention to Embedded Python which is not a feature but a major evolution (Révolution ?).

Hi Mike,

Indeed, there is no HealthConnect (HealthShare Connect) Community Edition, but with IRIS for Health Community edition you can do the same as HealthConnect and even more (FHIR server).

Great article and very useful.

In one of my project, I have almost done the same but instead of using env var, I use an mounted xml file of default settings :

LoadSettings.mac in Interoperability NameSpace

ROUTINE LoadSettings

#Include Ensemble

UseXMLVariables() PUBLIC {

	Try {
		// mounted file of default settings
		set tFileName = "/usr/irissys/conf/DefaultSettings.xml"
		if ##class(%File).Exists(tFileName) {
			do ##class(Ens.Config.DefaultSettings).%Import(tFileName)
			write !,"File : "_tFileName_" loaded the defaultsettings",!
		}
	} Catch e {
		s ^%zStartupError=e.AsStatus()
	}
}

%ZSTART

ROUTINE %ZSTART

#include %occStatus
SYSTEM() PUBLIC {
	/*
		Initial plan to use this as startup configuration.
	*/
	Try {
		New $namespace
		Set $namespace ="IRISAPP"

		Do UseXMLVariables^LoadSettings

	} Catch {}
}

Hi Evgeny, I confirm that irispip is not working, if you want to install python package you shall use pip3 or /usr/irissys/bin/irispython -m pip

Guillaume Rongier · Feb 8, 2022 go to post

If you don't want to create new data on the FHIR protocol, you must use the PUT verb with an ID instead of POST.

PUT creates the resource with the specified ID if the ID does not exist, otherwise it replaces the pre-existing data.

POST always creates a new resource with a new ID, that's why the ID is not mandatory when POSTing.

For automatic transformations from HL7/CDA to FHIR, there is the possibility to define the ID for some resources and thus to avoid duplication.

Below is an example of code to transform an HL7 payload to SDA by specifying the ID of the patient in order to avoid duplicating this resource, after that you can transform this SDA to FHIR with no duplication of patient.

/// This is a custom business process that transforms an HL7 message to SDA format (an internal healthcare data format for InterSystems IRIS for Health).
/// To use this class, add a business process with this class to the production and configure the target. The default target will send the SDA to a component
/// that converts the data to FHIR.

If you are using Ensemble you can use EnsLib.SQL.Snapshot.

This helper class can persist ResutSet in global :

Set rset1 = ##class(%ResultSet).%New()
set sc = rset1.Prepare("Select * FROM Ens_Util.Log")
Set:+sc sc = rset1.Execute()

set snap = ##class(EnsLib.SQL.Snapshot).CreateFromResultSet(rset1)
set glb = snap.%GblRef

If you are not using Ensemble, I guess you will have to build this kind of helper class by your self.

You still need the iris hibernate dialect.

You can find it here : https://github.com/intersystems/quickstarts-java

You will find here a demo of a quarkus rest crud api with iris as a database.

https://github.com/grongierisc/quarkus-iris

It's not using the Hibernate ORM but this shouldn't be an issue.

the repository is updated to show you how to play with quarkus + iris + orm + iris dialect :

https://github.com/grongierisc/quarkus-iris/tree/master/quarkus-iris-orm-quickstart

Hope this help, can't help you more with just config files.

I publish a PR to your repo.

What I did, I removed your hibernate jar, doesn't know what is in, so I directly used dialect code.

Then, in you property files you named the iris connection string : quarkus.datasource.reactive.url
instead of quarkus.datasource.jdbc.url.

That's it.

I did a last PR.

Many small fixes (check every commit).

Now I can't help you more, it's java stuff and it's no more related to IRIS.

For now, it's not possible in pure python, because the select namespace is specified by the environment variable IRISNAMESPACE, and environment variable can't be change in the parent process, I have tried by reloading iris module with no success.

To achieve that, for now, as Robert says, you have to create an helper method in objectscript ... :(

Class Embedded.Utils
{

ClassMethod GetNameSpace() As %Status
{

    Return $namespace
}

ClassMethod SetNameSpace(pNameSpace) As %Status
{
    zn pNameSpace
    Return $namespace
}

}

Python :

import iris

print(iris.cls("Embedded.Utils").GetNameSpace())
try:
    print(iris.cls("Security.Users").Exists("SuperUser"))
except RuntimeError:
    print("Wrong NameSpace")

print(iris.cls("Embedded.Utils").SetNameSpace("%SYS"))
try:
    print(iris.cls("Security.Users").Exists("SuperUser"))
except RuntimeError:
    print("Wrong NameSpace")

What a great example of IRIS Embedded Python + Dash Framework, very instructive.

You are using mostly sql query + dataframes, I can't wait to see another example of dash with SQLalchemy on IRIS.

The SQLalchemy toolkit for IRIS is expected in the next coming month.

Well done,

This driver is a game changer. It sets the foundation for complex projects based on python and IRIS.

I can't wait to see new projects based on Django and IRIS.

If you want to discover IRIS for Health with some samples, the best way is to install ZPM (community package manager). More info here : https://community.intersystems.com/post/install-zpm-one-line

Then, you have access of almost all application in OpenExchange.

Let's have an example with csvgen-ui : https://openexchange.intersystems.com/package/csvgen-ui

zpm "install csvgen-ui"

In OpenExchange you will find may example about rest API, web app, and so.

Great article !

Is it possible to use a custom image from a local docker registry with Kubeless ?
