1. Blockchain

As I am writing this article, Bitcoin costs less than one-fifth of what it used to be at the pinnacle of its success. So when I start telling someone about my blockchain experience, the first thing I hear is undisguised skepticism: "who needs this blockchain stuff now anyway?"

That's right, the blockchain hype has waned. However, the technologies it is based on are here to stay and will continue being used in particular areas.The Internet in general offer tons of materials describing the general usage of these technologies

Sounds odd - but I encountered it - twice now. Cache was restarted. in that period the primary journal directory was full and it was writing to the secondary journal directory. So upon start-up, it was quite obvious that it was not going to write to the primary. Cache reported this but was able to continue with the start-up but writing to the secondary. All of a sudden it doesn't recognize the 'primary' config any more and started saying 'Alternate and primary journal directories are the same'.

Handling Errors

I have a case where our EMR is sending data, but not all the values needed for the Ancillary are valued properly and causes that message to error/halt processing on the Ancillary system, not ideal but its what they do. I would expect them to still process the message except that 1 field, but they don't.

I want to add validation to make sure certain fields are valued correctly for the Vendor.

So I add some statements to take those items that don't pass this validation out to a batch file with headers.

Multiple joins in a SQL query

HI,

I have a query like below but its syntax is not accepted by Cache.

I would like to perform a left join on two tables first and then make a inner for this result with another table.

Given the constraint that we only allow one SELECT in the query, it is possible to achieve this semantics ?

Thank for your help.

Select *
FROM ( sample . employee e
LEFT JOIN sample . company c
on c . id = e . id ) g
JOIN sample . vendor v
on v . %id = g . attr

Programming and languages

Being a programmer nowadays is basically the geek version of being a polyglot. Of course, most of us here, in the InterSystems Community, “speak ObjectScript”. Howeever, I believe this wasn’t the first language for many people. For instance, I had never heard about it prior to getting the appropriate training at Innovatium.

An error occured when HS.IHE.XDSb.Registry.Operations on the BUS sends query request to the registry. The error is

Error 6242: HTTP request to SOAP webservice returned unexpected status: 403.

Any thoughts as to why? The settings on the components haven't changed. The process worked a few days ago.

Hello,

Last weekend we've updated our Caché version to

Versie:Cache for Windows (x86-64) 2018.1.1 (Build 312U)

I'm using Studio to develop. I've been using the built-in debugger and it has been working nicely. But now, since the upgrade, I'm getting this error when trying to debug any routine or class method:

Hi-

I am trying to figure out how to compare two dimension values in a MDX query such that records where two dimension values are the same will be filtered out.

To test this, I have modified the HoleFoods cube in SAMPLES namespace to have a new dimension called RandomRegion

I want to create a MDX query where the [Outlet].[H1].[Region] value is not equal to the [RandomRegion].[H1].[RandomRegion] value.

Here's the query I need to add the filter to:

Hi Community!

There are two general ways to execute arbitrary SQL in serverside ObjectScript code: EmbeddedSQL and ObjectScript SQL a.k.a. Dynamic SQL.

E.g. if we want to get the value of the property of instance with a certain ID using SQL we can do:

&sql(SELECT Name INTO :name FROM Sample.Person WHERE ID=1)

write name

Same result with %SQL.Statement:

set rs=##class(%SQL.Statement).%ExecDirect(,"SELECT Name as name FROM Sample.Person where ID=1")
  do rs.%Next()
  write rs.name

Hi All

It's been 6 weeks since my original article sad
- - - - -but I have been busy on this project

I have been looking at/thinking about a replacement for ZEN for around 12 months but only really started in depth 4 months ago.
Also been in IT for long enough that I can "get a feel" for a product/technology and make decisions accordingly without going into great detail.
Any new technology has a learning curve and I don't want to waste time and effort on something that won't fly.
And, as always, I am looking to minimise the learning curve as I want to concentrate on delivering business benefit.

Sentiment Analysis is a thriving research area in the broader context of big data, with many small as well as large vendors offering solutions extracting sentiment scores from free text. As sentiment is highly dependent on the subject a piece of text is about (financial news vs tweets about the latest computer game), most of these solutions are targeted at specific markets and/or focus on a given type of source data, such as social media content.

Hey everyone.

I was wondering if anyone had come across a way of reformatting ObjectScript within VSCode.

I have the various Intersystems Extensions installed (InterSystems Language Pack, InterSystems ObjectScript, InterSystems ObjectScript Extension Pack, InterSystems Server Manager) but a formatter does not seem to be something included within this variety of extensions.
