Hi members,

I have these data :

and need to exploit the first character of cot field (Library CDU classification) like this :

I get this result... it's approximatively what I want... but I need it in just one line !

With mySQL I get it with just GROUP BY rcddate

In Cache SQL I have to add {fn LEFT(cot,1)} to get the counts of each first character of cot... and seems {fn WEEK(rcddate)} doesn't make the job !

There is a trick ? or I make something wrong ?

kind regards.

Hello everyone I'm newb using COS and
I would like to know What is the definition of ROUTINE in COS ?
is there anything related to Global?
is it all information that it's possible to persist on the database?

I've been accessing Cache tables from a developer/reporting side, but am now involved in a project to create a data warehouse for our application.  I'm trying to find a query I can use to return the sizes of all the tables in the database, so we can identify the largest tables and handle those individually.  Can someone give me a query I can run against our Cache database to return the sizes of all the tables from largest to smallest?  

Thanks for the help

Using Prometheus to monitor Caché ，when config application /metrics done， Prometheus connection error: “server returned HTTP status 404 Not Found”

When i use &sql(SELECT ......)  in Cache I can watch the generated code
In the generated .int code and see what is happening.
Just with my normal rights

Now in IRIS I have just 4 line calling some class %sqlcq.***
With enough rights i find there is no such class but the generated .int routine
%sqlcq.IRISAPP.xEZgUjdXCCgQdZQPpRdOye1Ci2ue.1
That holds the code that i had in my .int on Cache

Can i switch this back somehow ?

Hello everybody

I'm in need of a lot of help from you.
I work in a company with all system cached script, using global.

I need to develop web applications accessing the cache database, and global.

Could you help me indicate the best language option to develop web applications, and easier to access cache, and if possible send me some examples of applications accessing globals.

I thank you all.

Hi All,

I would like to download odbc drivers for Cache database to be able to install it on our SQL server.

I am trying to create a linked server to Cache database.

I couldn't find a link for the drivers, there was one post with FTP reference to download but it doesn't seem to work.

I will be grateful for any help.

Thank you

Is InterSystems ODBC driver backwards compatible? If I use cache version 2018, can I upgrade the ODBC drivers to the 2021 version or it is better to upgrade to the 2018?
 

I programmed some server command by my own. That server commands worked fine for a long time.

Suddonly I received 

Studio Action "Attempted Edit" not supported on 127.0.0.1:57772[CTAE01]

by using one of my server commands.

There is an explanation:

Error running command vscode-objectscript.serverCommands.contextOther: Running the contributed command: 'vscode-objectscript.serverCommands.contextOther' failed.. This is likely caused by the extension that contributes vscode-objectscript.serverCommands.contextOther.

Can you help me to solve that issue?

When using an undimensioned array is there a way to write the array to a file? Something like this

DIM C()
C('TEST') = 2
C('WEST') = 5
C('BEST') = 1
WRITE C on myfile, 1

Pouring The Coffee: Creating and scheduling a task

Don't you wish a fresh, hot cup of coffee could be waiting for you right when you get into the office? Let's automate that!

Cache and IRIS come with a built-in Task Manager, which should have a familiar feel to those used to using the Windows task scheduler or using cron on Linux. Your user account will need access to the %Admin_Task resource to use it, and you can access it in the management portal under System Operation -> Task Manager. When first installed, there are roughly 20 types of task that you can schedule.

November 19, 2021 - Advisory: Apache Web Server provided with InterSystems kits – Vulnerability reports

InterSystems kits include an Apache web server, which provides a convenient way for customers to interact with the Caché/IRIS Management Portal without needing to install an external web server; however, this web server should never be used for production instances, and customers must install a web server that fits their specific needs and security/risk requirements.

Recent tests have noted some security issues with the currently included Apache web server.

I often get this message when trying to attach to the routine second time. The only way I was able to fix this is by restarting the Cache server.

Then I can do debugging once, but second time, the error pops up again. Very annoying. Is there a way to fix that without restarting the server ?

Thank you

I'm attempting to use the .NET Entity Framework provider that is provided by InterSystems (see: https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GBMP_eframe).  In our environment, the "Support Delimited Identifiers" option is turned off and we are not allowed to turn it on without significant testing effort.  When this setting is off, the SQL that is generated by the Entity Framework provider is not considered valid and therefore the provider doesn't work (it DOES work, however, when this setting is turned ON).

Do you know of any way to work around this issue?

InterSystems technologies are renowned for their high performing databases, which support the systems and operations of many organisations. However a key ingredient to this success is the quality and maintainability of their code. 

The quality of code can impact everything from speed and ease of fixing bugs and making enhancements, to the overall performance of your organization and your ability to get ahead in the marketplace. 

By ensuring your code is maintainable, you can reduce approximately 75% of the systems life cycle costs*. This is why, at George James Software, the solutions we build are always straightforward and written in high quality code - because we know that this solid foundation can positively impact the rest of your organization. 

With a maintainable system you're able to reduce your overall maintenance as any issues that occur are significantly faster to identify and fix. This means you're free to allocate that time and budget to enhancements, enabling you to get the most value out of your applications and ultimately better support your organization. 

Keep an eye out for our next few posts about what a maintainable system looks like and the tools that can help you keep your code maintainable, in order to help you to reduce those maintenance costs.  

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.

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
