#Caché

Hi,

I have a requirement to convert few screens having character based interface built in Cache to a web based interface in Java while still keeping Cache as the backend which means database will remain the same. Wanted to know if we have any tool in the market which can help doing that keeping in consideration that these screens in cache are using mumps code.

If we don't have any tool, would appreciate if someone shares their experience in the manual conversion as well.

Hi all

I'm trying to recreate this method below in Cache/IRIS.

https://en.wikipedia.org/wiki/Luhn_mod_N_algorithm ISO-7812-1 (LUHN-10)

I've been following the javascript example. It seems simple in theory but i'm struggling with which cache methods to pick.

$LENGTH, $System.SQL.FLOOR() - seem ok

$EXTRACT - I think for .charAt (though may need to correct base)

$FIND - for .indexOf

Any suggestion which would be the best ones for the job?

So I am working with an inherited SQL query that queries 8 different tables. 5 of which have over a million records.
I have 3 different servers.

Server 1, Server 2 and Server 3. They all have the same data/tables/structure across all servers.
Server 3 has an Iris database engine and the other 2 are Cache 2015.1.4.

I have a problem with views and performance across the servers being inconsistent.

Thankfully Server 1 is the current live server that performs "fast enough".
Server 2 is being synced from Server 1 and acts as a report server.

Do we hv any command to prevent the execution of update/delete SQL w/o “Where” Clause？

Dear experts,
Can you give tips to solve this issue?

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

Hello All,

I have a class method on the DocRepo server that needs to query the data value of a global variable on the Edge server.

I have looked at the documentation for 'Global Structure,' but I didn't find anything that helped.

Global Structure | Using Globals | InterSystems IRIS Data Platform 2022.1

I am able to access this global easily from the Edge server using the $Get function, but I need to access it from the DocRepo server.

Hello!

I'm new to the system I'm working on, and I have a part of a statement that needs to grab the previous month.

....and MONTH(TX3.date_of_service)= MONTH(dateadd(mm,-1,GETDATE()))

However, when it hits January, I'm left with month 0.

Does anyone know a workaround to grab December of the previous year, while still functioning normally for the rest of the current year.

Thank you!

Has anyone had success with passing in a collections property within a SOAP request to a Soap Service in Ensemble? Please reply with how you set up that collections property. I am able to successfully send a SOAP request correctly containing the elements of the collection property to Cache, as seen in a custom soap log file which I am using to troubleshoot. But the collection property in the Ensemble request is not getting serialized, meaning MyContainers has nothing.

My.Request consists of a property, MyContainers, which can have 0 or more Containers (My.Container)
