Hello,

I am trying to use %ZEN.proxyObject to send out in JSON format so I do:

set tProxyRequest = ##class(%ZEN.proxyObject).%New()
set tProxyRequest.notanumber = "28001"
set tProxyRequest.aboolean = "true"

set tBody = ##class(%GlobalCharacterStream).%New()
do ##class(Ens.Util.JSON).ObjectToJSONStream(tProxyRequest,.tBody,"aelotwu")
w tBody.Read()

and I get:

Hello,

We are working with a vendor who only accepts JSON as payload. We are currently still on Cache/HealthShare, not IRIS. Since we have to send Continuity of Care Documents, this raises issues with Long Strings (some CCDs can be quite large and in addition to that, they have to be b64-encoded which increases their size even more).

My question is: if we were to go on IRIS and use %JSON.Adapter, storing the encoded Stream in an object's Stream property, would calling %JSONExport() on this object produce the desired JSON? Or would we have to call %JSONExportToStream()?

Anyone know if it's possible using cache objectscript (or something else maybe) to reference an object property using a variable? For example:

s obj={}

s obj.prop1="hello"

s var="prop1"

w obj.var <== which would result in a reference to obj.prop1 and write out "hello"

Code migration using VSCode

I am fairly new to using VSCode. I have used VSCode to create some files on our Test Server, now I need to move them to Production.

Looking through the VSCode extension documentation, maybe I missed it but how to I migrate code from one workspace to another. In Studio I was use to exporting the code into an XML and just being able to import it on the Production server version of Studio.

Thanks

Hi All, I am a Data Architect and am trying a method of deploying alter statements onto Cache DB.

My Data Modeling tool generates alters as this.. So question is if the Cache has a way to rename table? If so what is it?

ALTER TABLE <SchemaName>.GROUP_TYPE_NODES RENAME TO GROUP_TYPE_10082019140110000
;

This is giving error.

I like to be able to call an "autohotkey" executable message box from within a running Cache routine executing as a jobbed routine. The autohotkey executable displays a small pop-up window with a message and an "OK" button .. and will time out in 10 seconds if the user does not press the OK button.

Although $ZF(-1,cmd) executes (where "cmd" contains a simple batch command e.g. @c:\autohotkey\warning.exe), no interactive window appears and, once the autohotkey routine times out, the calling cache routine simply continues.

Hello All,

I connected the Cache from Power BI using ODBC connection. And I can able to view the tables but I could't able to view the data records. getting some error when I shoot on the table name. I couldn't trace what I'm missing. Please help me.

Error Message: "Value cannot be null. Parameter name: exceptionType"

SQL Query returns x00

Hey Intersystems Community-Member,

Following Issue: When I update a SQL table like (update OnlineV3Admin.ParameterApp set popuptext = '' where ID = '1') and then read it for my Json WebService there is a /"x00" in my Json.

What is the best option to disable that? I need here a empty String and not /x00.

Any ideas?

Best regards,

Hello,

I need to create a util function that loops thru every character in the data, execute a $ASCII() against it. If it falls outside the realm of extended ASCII we toss it.

the function should receive a string, execute a for...loop across it's length and use $ASCII to evaluate the character. Also the function should return an output argument that indicates if the string is UTF8 valid or not.

could anyone help me with this?

I'm running Windows 10 x64 Pro 20H2 with Intersystems Cache ODBC driver v2018.01.00.184. I've setup a System DSN using the 64-bit of ODBC Administrator.

I've been getting inconsistent results using my regular application (Microsoft Power BI) which I use through ODBC to query my hosted TrakCare T2017 instance.

Using Microsoft ODBC Test Tool (part of MDAC 2.8 SDK) I can verify I get the same errors as in Power BI. They seem to be ODBC driver related but I can't pin it down.

As we all well know, InterSystems IRIS has an extensive range of tools for improving the scalability of application systems. In particular, much has been done to facilitate the parallel processing of data, including the use of parallelism in SQL query processing and the most attention-grabbing feature of IRIS: sharding. However, many mature developments that started back in Caché and have been carried over into IRIS actively use the multi-model features of this DBMS, which are understood as allowing the coexistence of different data models within a single database. For example, the HIS qMS database contains both semantic relational (electronic medical records) as well as traditional relational (interaction with PACS) and hierarchical data models (laboratory data and integration with other systems). Most of the listed models are implemented using SP.ARM's qWORD tool (a mini-DBMS that is based on direct access to globals). Therefore, unfortunately, it is not possible to use the new capabilities of parallel query processing for scaling, since these queries do not use IRIS SQL access.

Meanwhile, as the size of the database grows, most of the problems inherent to large relational databases become right for non-relational ones. So, this is a major reason why we are interested in parallel data processing as one of the tools that can be used for scaling.

In this article, I would like to discuss those aspects of parallel data processing that I have been dealing with over the years when solving tasks that are rarely mentioned in discussions of Big Data. I am going to be focusing on the technological transformation of databases, or, rather, technologies for transforming databases.

Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. Previously, I outlined the basic steps to install and connect Node.js to Caché and make it's powerful multi-model database capabilites available for use with Node.js. You can use Caché as a NoSQL-, document- (with unique key-level access!), SQL- and object-database with Node.js. When developing JavaScript applications, you'll see how powerful this combination is and makes Caché a perfect fit for Node.js.

In the first part of this article series I will show how to get started with the React framework, one of the most popular frameworks currently taking over front-end development. In the next parts you'll learn how to connect a basic web app to a Caché back-end.

You'll see, it's very easy to get started with this technology - you can even compare the amount of basic knowledge you need to COS because you only need to know a few basic concepts to start!

Hi,

I seem to be able to execute sqlproc using the convention defined here https://docs.intersystems.com/latest/csp/docbook/Doc.View.cls?KEY=GSQL_q... provided the package/folder is a single level. As, soon I have a nested folder structure I get an error while trying to execute this.

For instance,

select id, Utils.Users_getRole(id) roles from users.users

Hi Developers!

Want to raise security discussion today!

Let's discuss how InterSystems security for applications works. In general, the concept is clear: we have Resources (what to protect), Roles which combine a set of privileges and accesses to Resources and Users which can have this or that Role.

But there is also a concept of Application which also could have a Role.

So you either provide a Role for a User or for an Application.

What do you use in production? What is your strategy and why? Pros, cons?
