#InterSystems IRIS

Our ERP solution runs on different sql databases (such as ms sql and posgre). We are using the same code for all plattforms, doing database-specific changes in the db driver for each type of database.

There is one function in our program, where the user can store long text to discribe something, which is used in print and web. This text is treated/stored as html and can include pictures. The pictures in the html are stored base64 coded inside the html and the html is stored as text in a column. In other database systems, this is treated as TEXT or BLOB, and workings just fine.

I am trying to write a message to a Kafta cluster programmatically (i.e. not in Ensemble or using a Production) using %External.Messaging. I am consistently getting a 'topic not found error' even though I have created the topic on the cluster. I dug into the client I created an when accessing the property KaftaClient.jclient.gateway I get the following output:

Most of the databases with SQL access offers the DATE_TRUNC function or analogs. This helps to easily truncate a date by any part while keeping the DateTime in a valid format

Named parameters can be achieved with SQLAlchemy :

from sqlalchemy import create_engine, text,types,engine

_engine = create_engine('iris+emb:///')

with _engine.connect() as conn:
    rs = conn.execute(text("select :some_private_name"), {"some_private_name": 1})
    print(rs.all())

or with native api

from sqlalchemy import create_engine, text,types,engine

# set URL for SQLAlchemy
url = engine.url.URL.create('iris', username='SuperUser', password='SYS', host='localhost', port=33782, database='FHIRSERVER')

_engine = create_engine(url)

with _engine.connect() as conn:
    rs = conn.execute(text("select :some_private_name"), {"some_private_name": 1})
    print(rs.all())
