#Caché

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?

There is an undocumented command, $preprocess, that can be called as below. In this case it takes the class name and converts its code into a text array. That includes comments as well. Two questions about it if you know:

Hi ,

I am trying to retrieve the contact type column data of a patient based on the recent date as shown below.

for instance

contacttype Datefrom

contact 1. 24/03/2020

contact 2. 20/05/2021

i need to retrieve the second contact2 based on the recent date.

i tried like below but not working .

Case max(datefrom) >0 then contacttype

End as contacttype

Can anyone please tell me why this is not working.Any other options?

Thanks

I need to show the absence of data, so I have to join the list of predefined values with a result of a select statement.
However, it seems like Table Value Constructors in JOIN are either not supported, or I do not understand the syntax.
Basically, I am going for something like this:

Select v.valueId, m.name 
 From (values (1), (2), (3), (4), (5)) v(valueId)
     left Join otherTable m
        on m.id = v.valueId

Is it supported in Cache SQL or not?

Is there a way of coding in ZEN for the graphic below for ZEN PDF reports?

Hi, Community!

Please share your experience on code deployment on production site. Do you compile ObjectScript on Production? Is it OK?

Or you only compile on Test site and copy cache.dat to a Production?

objects in javascript :

var oM = new Object;

var mMode=["down","up","click"] ;
var key,val ;
for (key in mMode)
{

val = mMode[key] ;
oM[val]={} ;
oM[val].id ="" ;
oM[val].type ="" ;

...

}

so I can access the .type directly as :

oM.down.type

or:

oM["down"].type

what is the syntax in CACHE or IRIS, to achieve such approach via class/key/property...?

acctually: class/object/key/property anlaogue to ^GLOBAL(key,"property")=val

Let's say I have a persistent class Sales.
I need to create a report that shows the amount of sales for each branch.
By simply using the class Sales for the source of the cube, I can show what I want with one little exception - the branches that did not have any sales are not shown.
Is there a way around that that does not involve creating a whole new table just for this cube or using a Data connector (they have horrible documentation and I am unable to figure out how to use them properly)?

I am getting the below error while navigating a next page from the list in Management Portal

Must have Java Enabled to use hyperevent call

Unable to locate CacheCSPBroker applet!

I have already enabled Java in Java Control Panel

Any help is much appreciated

I want to consume external websocket api, URL looks like this:

wss://site.com/ws/v2/?&token=<token>

Checked with external tool (Simple WebSocket Client) that websocket works and I can consume the data.

In Cache the relevant functionality is offered by %IO.Socket class.

set sock = ##class(%IO.Socket).%New()
set sock.SSLConfig = "MyEmptySSLConfig"
set sock.TranslationTable="UTF8"
do sock.Open("site.com/ws/v2/?&token=<token>","443", 10,.sc)

However I get this error:

Hello everyone!

Some time ago, I changed the configuration in SQL Runtime Statistic to "Turn on Stats code generation to gather stats at the Open and Close of a query". With this change, the CACHE base (cache/mgr/cache/) has grown a lot to reach 198GB.

Yesterday, I returned the configuration of SQL Runtime Statistic to the default which is "Turn off Stats code generation" and the cache base is no longer growing.

My question is?

Hello everyone,

I don't want to believe that Intersystems didn't add a method/process/rule to sort alphabetically a list of names (in array, $ LB or whatever)

I haven't found any documentation about this. I've even tried comparing two strings but have not found a solution.

My cry for help is...

Does exists any command to compare two strings and check if one of them is lower or upper according to aphabet?

Please, give me a light in this dark

Best regards.

I am new to Cache, we are trying to move a 4 TB database over the internet, but this will be take too long to copy the single backup file. In Oracle and MS-SQL Server there is an option of doing log shipping. Is there such an option in Cache?

I want to copy the initial backup file one weekend, then keep sending the Journals (logs) the new location.

Thank you,
