#Caché

Hey guys,

I need to create a .dbf file,  

How can I create this type of file?

There is some lib or plugin to do that?

In the Caché Foundations course, students are learning about Caché Development and ObjectScript syntax at the same time. To help students complete the exercises, we provide an ObjectScript Quick Reference (aka "the Cheat Sheet").

It is not a reference for all of ObjectScript! It is a list of the ObjectScript commands and functions that students use during the course, along with common syntax for objects, collections, etc. It also contains some useful macros.

We are providing a pdf version to the Developer Community.

Hello!

While creating DBF file ,  I get unreadeable symbols. For example ╠┼╥└╦╦╙╨├╬┬

How set encode to WINDOWS-1251 ? 

This code doesn't help

w $zconvert(fldValue,"O","CP1251")

Thank you!

Hi, I am new to InterSystems database. I am developing an application to display real time skillset statistic data, including max waiting time per skillset. I have access to the database through ODBC, using InterSystems ODBC driver. But I don't know from which table or view to get real time data of maximum waiting time per skillset. I appreciate any advices.

Hi

I am in the process of trying to implement version control software with studio.  Has anyone got any recommendations (either Linux based/windows based) as a place to start I have installed Gitlab and I wanted to know whether anyone has come across any obstacles using this.

I was also wondering whether anyone has developed any hooks for Gitlab that works well with Studio as I would prefer if there was a more integrated solution with studio?  Any help with this would be great.

Thank you.

Kind Regards,

Salma

In my previous article I demonstrated the steps to connect to Caché from Appeon PowerBuilder by using ODBC.
In this article I will demonstrated how to Retrieve data from Caché with Appeon PowerBuilder (https://www.appeon.com/products/powerbuilder) by using ODBC

I am using Company.cls from Samples-Data (https://github.com/intersystems/Samples-Data/tree/master/cls/Sample) 

So Let's start:

Step 1 : First of all we need to establish a connection (https://community.intersystems.

Hello,

I don't know if the title is accurate enough. I have a legacy code that I need to optimize. It's a routine written in objectscript. It accepts 4 parameters and runs 6 nested FOR...$ORDER reading a big global.

The thing is when I run the routine the first time it takes around 60 seconds to run. If I run it again it takes 5 seconds. If I wait around 6 to 10 minutes to run it again, it takes 60 seconds again, but if I run it every 1, 2, 3... minutes it still takes only 5 seconds to run.

Hi guys,

My client has a requirement to add a column of random numbers to the query result.

I wrote a function as below:

Class Utils.SqlUtility Extends %RegisteredObject
{

ClassMethod GetSomeNumber(intInput As %Integer) As %Integer [ SqlName = GetNumber, SqlProc ]
{
    Return $R(intInput)
}

}

But in the returned sql result, every row share the same value, as below,

SELECT Utils.GetNumber('456'),
ID, Citizenship, DOB, FirstName, Gender, IDNumber, LastName, PatientNumber, PhoneNumber
FROM CDR.Patient

How may I refactor the function or sql to make the random value really random on each of the rows?

Thanks.

Hi community!

I want to introduce you a new powerful feature from our static code analyzer objectscriptQuality. 

Each time a new IRIS version is released, you need to prepare a roadmap for migration in which you need to spend a lot of time on testing to find where your code is not accomplishing with the newer version. Or maybe you need your code to be compatible with multiple IRIS or Caché versions.

You can now simplify the task running the analysis for the different IRIS and Caché database versions, so you will get the failing code before you start to test.

I need to execute multiple DELETE statements in a single query like this

DELETE FROM TableName WHERE ID = 2;
DELETE FROM TableName WHERE ID = 3;
DELETE FROM TableName WHERE ID = 4;

However It does not work when there're more than 2 statements and gives me an error

Expected FROM found WHERE^DELETE FROM TableName WHERE

Using IN is not an option.

We're hosting our Deltanji and Serenji user group session tomorrow - there's still time to register, if you haven't already. 

We'll be showcasing some advanced features of Deltanji and Serenji in VS Code with time for a discussion - so feel free to bring along any problems you need help solving or share your feedback on our tools. We'd love to hear your thoughts. If you're interested in our tools this is a great chance to hear what others have to say, as well as asking your own questions.

Date: Wednesday, November 3rd

Time: 11-12pm EDT / 3-4pm GMT.

Let us know you'll be attending on Eventbrite. 

We hope to see you tomorrow, but if you're unable to make it you can email me at laurelj@georgejames.com and I can share a recording of the session. 

I have created on class method which execute below command

From terminal : _System account works fine where code=0

From Studio : _System account give syntax error where code=1

I am relatively new to Intersystems cache database management. As I understand it, a database is set with a maximum size or unlimited and the size of each space allocation for the database is defined. My understanding is that the cache database will then manage the allotment of space to the database as the current space allocation is consumed. Though I do not know why one would want to do this, I have been told that the space allocation to a database can be set to be handled manually. This is something, if true, I was not aware of.

Hi Developers! As part of an internal company hackathon at InterSystems, I'd love community feedback on a few topics. Feel free to chime on any/all of these via comment or direct message to me.

1. If you were to launch a new application/project, what problems would you need to solve right off the bat? What technologies would you use? Why?
2. What are the most common and repeated problems that you find yourself solving?
3. Where in InterSystems' technologies do you spend most of your time?
4. In a solution you have recently implemented, how were your time/efforts allocated? (e.g.

Hello Caché-Community,

where can I download the current ODBC Drivers for InterSystems Caché.
The links in the following post don't work anymore:

Is there a way to ensure a certain global(s) are always in buffer ?!

Is there a method call to check if a global is in buffer ?

I have a workstation with a CACHE instance up and running.

On that same workstation there is also an instance of IRIS (fresh install). I would like to migrate manually the CACHE database to IRIS (ideally, all globals, routines and classes).

What I tried is to copy C:\InterSystems\Cache\mgr\CACHE.DAT to C:\InterSystems\IRIS\mgr\IRIS.DAT (after shutting down both instances) but it does not work.

I got the following message : (112) The service for the IRIS instance did not start.

Is there a better way ? (eg: using Portal or some API from command line).

Hi all.

I'm trying to create a route rule that can call to a web service according to a parameter of a message.

My first attempt is the following:

I have a common class with all information, BuscarHuecoRequest, and check what is the value of property "CodigoProveedor".

The table T_PROVEEDOR contains the list of code with the code of the provider, if is F, calls to WSF, if is C, calls to WSC, etc... Using a transformation to convert the values to this provider.

Hi,

I wonder if anyone tackled the following problem-

Sending a mail with an embedded image is straight forward using %Net.SMTP

S status=Message.AttachFile(Dir,FileName)

D Message.TextData.Write("..<img src=""cid:xyz.png"">..")

Outlook displays such an Email as expected- with the image in the body of the mail.

Gmail displays the image as an attached file.

There are a lot of suggestions online about this, but none is working for me.

Did anyone face and solved this issue?

Regards,

Nael Naseraldeen

First of all thanks for your help and time

We would need to find inside PID:3 which one meets the following condition:

PID 3.4.1 = "CAC" and PID 3.5 = "JHN"

We have been investigating how could we do it

We have achieved to get single fields in a call request as follows:

request.GetValueAt("ORCgrp(1).ORC:OrderingProvider(1).IDNumber")

##class(Ens.Util.Time).ConvertDateTime(request.GetValueAt("PID:DateTimeofBirth"),"%Y%m%d","%Y-%m-%d")

However, how would you recommend us to look for a specific field in PID meets a specific criteria?

How would you find inside PID if there are PID 3.4.

Hello everyone,

I would like to know what is the best terminal emulator in your opinion? I am using MobaXTerm, but  i'm having some difficulties with the charset configuration. 

Best Regards.

UPDATE:
It turns out it was just me being a dummy, and the snmpd was correctly telling me there is no value associated with that exact key. I should have used snmpwalk instead of snmpget to display the whole tree.
Original Post follows:
Hello!
I'm trying to set up SNMP monitoring on Caché, using documentation and this article
I'm running net-snmp on Red Hat Enterprise Linux Server release 7.3 (with CentOS repositories), and Caché version 2017.1
It looks like snmpd is running as AgentX master, and Caché subagent is running too
/opt/cache/mgr/SNMP.

Why is it not common to handle inclusion, alteration and exclusion rules directly in the Caché database, using their controls on web pages, as is usually done in other databases such as Oracle, SQL Server?

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

hello!

i have object bellow

Set object = ##class(%ZEN.proxyObject).%New()
set object.city = "New York"
set object.Target = "TEST" 
set object.Details = "TEST"
set object.RefCode = "123"
set object.Reason = "123TTTT"

I want to get string from json object. 

Could you help please ?

If I open a terminal and type the following commands, sc is an error:

set validator = "sc = ##class(%Library.Numeric).IsValid(""BLAH"")"
set @validator
write sc

At the end, when I write sc I get:

0 L'BLAH9
             DOCXT010,#e^zIsValid+1^%Library.Numeric.1^1e^^^1

However, if I call the following class method using the arguments "%Library.Numeric" and "BLAH", sc is undefined

 ClassMethod testvalidator(class As 

When it tries to write sc, I get:

And I can't figure out what's making that different.

The latest release of Serenji focuses on the debug experience. Not only can you now debug on the spot, no matter where you are or what you're doing, but we've also added some smaller features that will make debugging more straightforward. 

• Run and Debug CodeLenses - clickable links above each class method, procedure, subroutine or extrinsic function.
• Intuitive prompting for entrypoints and arguments - when debugging a class method, produce, subroutine or extrinsic function. 
• Shaded read-only background - to clearly differentiate between documents which are editable and those that are read-only. 
• Program output in debug console - output is shown in the debug console. 
• Serenji commands on Server Manager's namespace trees - allowing you to launch Serenji through Server Manager.
