#Caché

45

  

InterSystems Caché is a multi-model DBMS and application server. See more details here.

Documentation.

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?

Hello Community,

We want to send ALL updates from our Cache server to a remote SQL Server instance that will be used as a reporting data warehouse.

Has anyone done this already and if so what is the best way to go about setting this up?

Thanks

Regards

Mike

Hi,

I'm getting thousands of errors like the ones below:

2021-05-03 14:11:44 [SQLCODE: <-400>:<Ocorreu um erro fatal>] [Cache Error: <<READ>Dispatch+14^%SYS.BINDSRV>] [Location: <ServerLoop>] [Client info: <Username: KIORAS, Node Name: 3IK0VLS5UU, IP Address: 192.168.1.223, Executable Name: EXTRService.exe, Internal Function: B0>] [%protocol: <52>] $Id: //ce/2018.1.2/kernel/common/src/aclass.c#1 $ 23468 104

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)?

The boss (reasonable intelligent ;-) wants to connect to the cache database through Excel, but unless I explain what he's looking for (field names DB names etc) then I can see him continually coming back for "what's the link here and how do I get the delivery company name etc etc"

is there a SAFE way I can give him access to our database using an intelligent visual user interface.

I had thought about the SQL Query Builder within the management portal, but the thought of giving him access to all of the other functionality of the management portal.

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:

Cucumber / Gherkin integration

Are there any BDD testing automation implementations within Mumps/Cache Objects already in existence?

We are looking at using Cucumber for our Java regression test automation and would like to use similar feature file testing with the Cache code.


Looking to use something existing before building it.

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,

I have a quick question regarding TSTART, however not certain if there is an answer.

If I am inside the transaction and I loose connection - I always assumed that transaction would TROLLBACK, however it does not.

Is there anything special I need to set up with my TSTART, in order for this transaction to safely rollback?

*********

As example: Let's say I am inside the TSTART and setting up / altering some data and my VPN connection got disconnected. I kind of expect all the data to be rolled back.

Thank you,

Alex

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.

httpRequest POST file Upload multipart

1. is there a code example step-by-step, how to build each part ?

I tried the demo from intersystems doc's,

I checked it in .Net response, that didnot recognize the File-data part

2. I noticed, there is :

SET BinaryMIMEPart.ContentType="application/octet-stream"

but missing :

SET BinaryMIMEPart.ContentDisposition (as analogue, let say for VBA EXCEL )

or I do it via the:

Do BinaryMIMEPart.SetHeader("Content-Disposition",...) ?

that is not analouge for VBA

Log (Journal) shipping

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,

Eudoro

Cache code conversion tool

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.

Hello,

I'm using $ZF(-1) in a class method which will be invoked from a csp page.

What determines the environment of the spawned process? If I use $ZF(-1,"echo hello world > output.txt"), the resulting file is owned by cacheusr:cacheusr. However, when I use $ZF(-1,"printenv > output.txt"), the environment is from my personal unix account, no matter which Cache username I'm logged in under when running the web application.

Thanks
