Hi Community,

Imagine enabling your application to read text to your customer? This is now possible with the new IRIS feature, Embedded Python. With this new functionality IRIS can natively run any open source or commercial Python libraries natively. gTTS (https://pypi.org/project/gTTS/) is a free library that transforms text into audio using the Google Translate service.

SQL JSON_OBJECT

Hi.

I'm trying to serialize property of type %TimeStamp in SQL statement with JSON_OBJECT, but I get a raw string instead of JSON DateTime format string. %JSONExport method on the same object works fine.

Any ideas?

Regards,
Matjaž

Hi,

Is there a way to find the median in Intersystems Cache SQL? I know it is not available as an aggregate function. Also in SQL Server I could try something like: 

SELECT
(
 (SELECT MAX(Score) FROM
   (SELECT TOP 50 PERCENT Score FROM Posts ORDER BY Score) AS BottomHalf)
 +
 (SELECT MIN(Score) FROM
   (SELECT TOP 50 PERCENT Score FROM Posts ORDER BY Score DESC) AS TopHalf)
) / 2 AS Median

However, there is no PERCENT Keyword in Cache as well. Any suggestions?

Thanks

using SSH to connect to IRIS

Has anyone here successfully connected to a community edition version of IRIS through port 22 to localhost? I have been trying for hours and hours to connect a Mobaxterm terminal session to IRIS and am at a total loss. Im not sure if port 22 isnt opening at this point or if its a configuration issue on my part. I am seeing either "Remote side unexpectedly closed network connection" or "connection refused" when i try to run the SSH session. I have tried 22/51773/1972 etc port settings under add/edit server to no avail. Any help is appreciated. Thanks.

From time to time, we get the previous question in support, something or someone is using more licenses than expected, and we need to find what.

We have two scenarios. The first scenario is when we realize that the licenses are exhausted when the application does not work or when we try to connect through the terminal and get the "lovely"

Hello

We have a solution with an EnsLib.EMail.InboundAdapter as services that scan a mailbox on incoming mail with attachments.

When a new email arrives, the service sends the request (with a property %Net.MailMessage) to the process. In the process, we try to loop through and retrieve part 2 which we assume is the file.

set Part = pRequest.Mail.Parts.GetAt (2)

We can read out the file name:
Set FileName = Part.FileName

But how, and is it possible, to save the attached file to disk drive?

Hi guys,

How to find out the number of active connections (including SQL, http, tcp and all remote connections) of an IRIS instance? A core based license is used.

I've checked the document and find %SYS.ProcessQuery.

I'm currently using this sql:

select count(distinct Pid) From %SYS.ProcessQuery
where ClientIPAddress is not null
and ClientIPAddress <> '127.0.0.1'
and ClientIPAddress <> 'localhost'
and IsGhost = '0'

Is it accurate or do we have a better option?

Thanks in advance.
