Hello Community,

How to convert the IRIS %DynamicArray into python list. I got " <THROW>TestDyncArray+1^MyLearn.Pyth.NewClass1.1 *%Exception.PythonException <PYTHON EXCEPTION> 246 <class 'AttributeError'>: <unknown exception data>" error when passing array values to python class.

Hi,

I was playing around with the python binding for caché (2018.1.4) and I ran into some problems.

When executing the class query "List" from SYS.Database the pythonbind interface throws an exception, that seems to be caused by a mismatch of the defined SQL datatypes for this query and what is actually returned (or the lack of type conversion in the pythonbind interface).

Is this a known issue ? Are there solutions/workarounds for this,
Or is this a bug ?

The details:

Hello,

First of all thanks for your time, thoughts, teaching and help:

We wonder how could we get the metrics from http://[Ip]:[Port]/api/monitor/metrics and use them in Kibana to chart statistics.

We would like to ask you how do you use the api monitor metrics, and as a second question, how would you suggest to utilize them in a third party software as Kibana to chart them.

We have thought to do the following:

Hi,

I am experimenting with Cache-Python binding. In the following piece of Python code

import intersys.pythonbind3

conn = intersys.pythonbind3.connection( )
conn.connect_now('localhost[1972]:SAMPLES', '_SYSTEM', '123', None)
samplesDB = intersys.pythonbind3.database(conn)
p10 = samplesDB.openid("Sample.Person",'10',-1,-1)
p10.run_obj_method("PrintPerson",[])

I'm trying to get started with IRIS for Health but every time I got to a step that asks me to install a .whl-package I cant continue. I'm getting an error that the file does not exist.

Here is the complete error message:

Pyodbc supports calling stored procedure , but if the IRIS Stored Procedure ROWSPEC has a column with datatype specified as %Date or %Time, Pyodbc fails to fetch it and throws this error.

"

pyodbc.Error: (' 2201', '[ 2201] [Cache ODBC][State : 22018 ][Native Code 22005]\r\nERROR #388: Unknown error, code 22005 (22005) (SQLGetData)')

"

on printing the cursor execute description, pyodbc reads the column as <int>.

So, I know that I can return a SQL Error message from my SQL Procedure written in ObjectScript, with code like this

$ cat <<EOF | irissqlcli iris://_SYSTEM:SYS@localhost:1972/USER
CREATE or REPLACE PROCEDURE test()
LANGUAGE OBJECTSCRIPT
{
 SET %sqlcontext.%SQLCODE = 400
 SET %sqlcontext.%ROWCOUNT = -1
 SET %sqlcontext.%Message = "test error message"
};

CALL test();

EOF
[SQLCODE: <-400>:<Fatal error occurred>]
[Location: <SPFunction>]
[%msg: <test error message>]

But I did not find how to do it with Python. I can't find %sqlcontext variable available there

I am in the process of creating a python report writer that includes the information contained in "License Usage" page of the management portal. I think I have a handle on the local values contained in the report using the %SYSTEM.License class I have those defined using these methods:

Current License Units Used - -> LUConsumed

Maximum License Units Used --> LUMaxConsumed

License Units Enforced --> KeyEnforcedUnits

License Units Authorized --> KeyLicenseUnits

I am sending an httpRequest from ObjectScript to a python server. I am not receiving a response in OS

OS config On the client side

// Create an HTTP request object
Set httpRequest = ##class(%Net.HttpRequest).%New()

// Set the server URL
Set httpRequest.Server = "http://127.0.0.1:8080"

// Set content type to JSON
Set httpRequest.ContentType = "application/json"

Hello everyone,

Im just wondering if there is any possibility to "Listen" to a cache DB? We have our cache DB somewhere else provided by a different company, we are provided the interface to connect to that cache DB so we can extract the cache DB every night.

Im just curious if theres a way to "listen" to the cache DB, so if theres any changes on the table in the cache DB, I could make a trigger to extract the table again.

I know i could just set my ETL every hour or so... but that would extract all the tables in cache DB.

I have developed a process that pulls data elements from a cache instance using the tools provided with the "intersys.pythonbind3" import. This is a windows box. After validating the process, the next step is to install the process on a site (Windows) that does not have an installed version of cache and access the cache instance remotely. But, since intersys.pythonbind3 is part of the cache install, I am not sure what to do to allow this process to function because of the missing import.

Hi,

I'm getting an unexpected behavior when using pandas function to_sql(), which uses sqlalchemy-iris. After the first execution, a transaction seems to be opened and all rows inserted are lost after closing the connection:

Hello there community,

I am pleased to say that i have started building a product and I have chosen InterSystems technology to be used in it.

But I have a confusion with regard to it.

I actually have to come to a conclusion to whether to use CACHE or IRIS.

I will be using a lot of data and also integrating it along with Python for DEEP and Machine Learning.

Also I do not have an idea of how to get the licensed version of either of that.

I want to connect IRIS system as it has all the database tables. on top of that I am creating a REST API in python. How can I connect to IRIS DB. here is my example code for connection

def connect():

connection_string = "localhost:1972/USER"

username = "_SYSTEM"

password = "SYS"

conn = iris.connect(connection_string, username, password)

after this connection is created but how can I get tables data. Please let me know more about how we can integrate IRIS database into a python REST API.
