#InterSystems IRIS

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

Preview releases are now available for InterSystems IRIS Advanced Analytics, and InterSystems IRIS for Health Advanced Analytics! The Advanced Analytics add-on for InterSystems IRIS introduces IntegratedML as a key new feature.

Hi Community!

We are glad to invite every developer who uses ObjectSript and VSCode plugin to the second webinar hold by the VSCode ObjectScript plugin developer on May 26 at 11:00 EDT.

You will learn how to develop InterSystems IRIS solutions using GitHub Development Flow with VSCode ObjectScript and Docker.

Speaker: @Dmitry Maslennikov, InterSystems Developers Advocate, CTO at CaretDev.

Hello!

I have a table pane component on my page. I want to get the contents of the table to send embedded within an email. Is there a simple (or not simple) way to get the HTML of the rows and columns to send this way?

Hi ObjectScript developers!

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.

Hi !

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.

Hi Community!

We are pleased to invite you to the upcoming webinar in Spanish: "Interoperability: HL7 productivity tools" / "Interoperabilidad: herramientas de productividad HL7" on April 29 at 16:00 CET!

What will you learn?

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.

I have the variable with literal.

Can I understand with ObjectScript that the literal is:

%String,

or %Integer,

or %Date,

or %Double,

or %Numeric?

What I'm looking for could be:

set variable="To be or not to be"

USER>w ##class(utils).GetType(variable) 

%String

set variable=42

USER>w ##class(utils).GetType(variable) 

%Integer

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.

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:

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.

Hi!

Is there a method in a persistent class that can return the current number of records/persistent objects in it?
