Question Oliver Wilms · May 27, 2020

Hello,

I work as a contractor for the Department of Veterans Affairs. I want to read data from an Excel workbook. I searched posts here and saw Apache POI suggested. I believe Apache POI is not approved for use within VA. I also believe we should be able to run SQL query against Excel. Has anybody done such a thing or are there other ways to read data from Excel workbooks?

Thanks

A More Industrial-Looking Global Storage Scheme

In the first article in this series, we looked at the entity–attribute–value (EAV) model in relational databases, and took a look at the pros and cons of storing those entities, attributes and values in tables. We learned that, despite the benefits of this approach in terms of flexibility, there are some real disadvantages, in particular a basic mismatch between the logical structure of the data and its physical storage, which causes various difficulties.

To solve these issues, we decided to see whether using globals — which are optimized for

Question Renato Banzai · May 26, 2020

Hi everyone! I was using the InterSystems Native API for Python and following the documentation I tried to use this method (https://irisdocs.intersystems.com/irislatest/csp/docbook/Python-Native/irisnative.iris.html#irisnative.iris.getAPIVersion after a while I realize that this method doesn't exist. Looking at the object I can see the method: irisnative.iris.getClientVersion which doesn't exist in documentation (and probably does the same thing)

I'm using the irisnative-1.0.0-cp34-abi3-macosx_10_13_x86_64.macosx_10_14_x86_64.whl

How can we fix the documentation (or the class method name)?

Hi ObjectScript developers!

How to Protect Your Belongings from Pests While Moving - Delicate ...

InterSystems ObjectScript is perhaps the best language on the planet to deal with globals - and it is an interpretable language.

Yes, it has a compiler. But even the compiler can compile some lines in ObjectScript which will then fire as bugs during the runtime.

There are some technics on how to avoid that such as unit testing, coding guidelines and your coding experience, of course ;)

Here I want to present to you the yet another approach to how you can reduce the number of errors in your ObjectScript runtime and enforce coding guidelines - it's an ObjectScript Quality tool developed by Lite Solutions, InterSystems solution partner.

See the details below.

In an ever-changing world, companies must innovate to stay competitive. This ensures that they’ll make decisions with agility and safety, aiming for future results with greater accuracy.
Business Intelligence (BI) tools help companies make intelligent decisions instead of relying on trial and error. These intelligent decisions can make the difference between success and failure in the marketplace.
Microsoft Power BI is one of the industry’s leading business intelligence tools. With just a few clicks, Power BI makes it easy for managers and analysts to explore a company’s data. This is important because when data is easy to access and visualize, it’s much more like it’ll be used to make business decisions.

If you work with interoperability productions of InterSystems IRIS or Ensemble, no doubt you are familiar with the Message Viewer page. The page supports filtering messages according to filter criteria you enter in the Basic and/or Extended Criteria sections. Extended Criteria conditions are specified as property-operator-value triples. Once you click Search button, such triples become WHERE clause conditions of a generated SQL query executed against message header/body tables.

As a side note, one can view recently generated message queries by following the instructions listed in the doc.

Most of us are more or less familiar with Docker. Those who use it like it for the way it lets us easily deploy almost any application, play with it, break something and then restore the application with a simple restart of the Docker container.
InterSystems also likes Docker.The InterSystems OpenExchange projectcontains a number of examples that run InterSystems IRIS images in Docker containers that are easy to download and run. You’ll also find other useful components, such as the Visual Studio IRIS plugin.
It’s easy enough to run IRIS in Docker with additional code for specific use cases,

Question Henry Pereira · May 20, 2020

Hi community,

I need to write an SQL query  to fetch a random record from a table, that table has millions of data.

In postgresql, for example, there is a RANDOM() function to do something like that:

SELECT column FROM table
ORDER BY RANDOM()
LIMIT 1

Is it possible to do something like that in Caché?

Thanks in advance

Hi Developers,

Please welcome the new video specially recorded by InterSystems Product Manager @Bob Kuszewski for the 3rd InterSystems Online Programming Contest on InterSystems IRIS Native API:

⏯ Using the IRIS Native API GitHub Template

 

What’s the contest about?

In the last year, InterSystems added and expanded Native APIs for Java, .NET, Python, and Node.js. The Native API provides high speed access to globals, the ability to instantiate and use ObjectScript objects, and fine-grained control over transactions.

InterSystems has corrected two defects that affect online backup of very large databases. Backups taken via external methods, such as snapshots or direct file copies, are not affected. These defects exist in all released versions of all InterSystems products.

The first defect only affects databases with more than 231 blocks. It results in a degraded database after restoring from an online backup. For example, databases that have a block size of 8 KB (the default) are only affected if they are larger than 16 TB. The correction for this defect is identified as RJF437.

The second defect affects

Note (October 2022): yape has been deprecated and replaced by YASPE, there is no more development on yape.


Note (June 2019): A lot has changed, for the latest details go here

Note (Sept 2018): There have been big changes since this post first appeared, I suggest using the Docker Container version, the project and details for running as a container are still in the same place  published on GitHub so you can download, run - and modify if you need to.
