hi

   I want to update  some columns in one table like this:

    update table1 set col1=%SYSTEM.Encryption_AESCBCEncrypt(col1, 'key')

but the error is 

ERROR #5540: SQLCODE: -359 Message: User defined SQL Function '%SYSTEM.ENCRYPTION_AESCBCENCRYPT' does not exist

what's the corect syntax?  Thanks!

InterSystems' iKnow technology allows you to identify the concepts in natural language texts and the relations that link them together. As that's still a fairly abstract definition, we produced this video to explain what that means in more detail. But when meeting with customers, what really counts is a compelling demonstration, on data that makes sense to them, so they understand the value in identifying these concepts over classic top-down approaches. That's why it's probably worth spending a few articles on some of the demo apps and tools we've built to work with iKnow. 

In the first article in this series, we'll start with the Knowledge Portal, a simple query interface to explore the contents of your domain.

Hi,

I have a situation where I write a character stream to a file. The file content gets signed and the signature is sent to a service provider together with the file content.

The signing is done using openssl.

This works perfectly on a dev PC, which is runnning Windows and has a little-endian architecture.

The problem is as soon as I do this on the server, which has a big-endian architecture, the signed value is incorrect according to the service provider.

The content is signed using RSA SHA256 with PSS padding.

I've had a look at $nconvert, $sconvert, etc., but can't get to a solution.

Is there a w

Greetings, 

How can I store a global name in a variable, ie: x="^G" and then use x like this, as if it were the global:  y=$o(x)  ?

Please advise,

Thanks... 

Greetings,

If given a global, how can I discover information on that global?  More specifically,  how can I discover how many indices it contains?  ie:  ^G(1,2,3,4,5)   How can I discover that there are 5 subscripts within the Global ^G if I did not already know.

Please advise, and thanks in advance for everyone's time.

It is my understanding that when a routine accesses a global it is temporarily stored in global memory. While the global is within global memory, any other routine would be able to readily access the global from memory and not from disk so long as the same node is being utilized.

For example, RoutineB() would be able to access ^Global(1) and ^Global(1,2) since RoutineA() utilized them, but RoutineB() would have to read ^Global(1,7) from disk as it was not utilized by RoutineA().

For my own sanity, I wanted to reach out and obtain clarification from the community as I have recently begun to doubt

Hello mates,

When turning on the “Archive IO” option within the business operations, it provides us the capability of seeing the input and output communication with external systems. For instance, watching the messages sent out + ACK message sent back .

Our production has got a scheduled task that runs daily (by default I guess, as many others) and is in charge of purging “Errors and log files”. And this is likely to be linked to the “Archive IO” feature, right?

The thing is, after tweaking the variable to keep it for 7 days, it doesn't seem to be working, as messages older than 1 day will be van

Hi everyone

Is there any way to change a class definition (especifically a query definition during the compilation time)?
The idea is: 
    I have an abstract class with a parameter where I will define the ROWSPEC of a query and some methods to populate e temporary table
The implementation class will override the parameter, specifying the ROWSPEC of this implementation, and the methods will populate the rows in the same format as the ROWSPEC.

I want to change the ROWSPEC of the inherit query according to the implementation of the overriden parameter.
What I've already tried to change the parameter d

Hi 

I have two persistent classes defined. Lets call it Parent and Child.

Child class is one of the property of Parent Class.

I would like to define a index on Child class.

So what is the default behaviour I defined a index on a non simple data type member?

Any possibility that I could customized the behaviour ? For example. Child class has three properties.

Could I configure the index to index any combinations of these three properties?

Thanks for your help.

Hello,

We need to consume files (right now using FileInboundAdapter) with a strict order.

Example:

File order will be A, B, C. Suppose A, B and C will be the names of the files.

Then B will never be consumed before A or after C.

How deal with this? Any idea?

I'm trying to recreate a smaller copy of our DEV machine on a sandbox instance.  I installed a new instance, and thought it would be a good idea to copy over a few cache.dat files from the critical namespaces (but not all of them), and start from there.

However, I can't compile any UI files in my new instance because I'm getting a <PROTECT> error on the %qCacheMsg global -- for any element that displays text (i.e. the first <label> that's encountered) the generated code is trying to get text from the global  ^%qCacheMsg("%Utility","en",node) = text -- from a node that doesn't exist.

Of course, I

Hi,

I have a UrlMap like the one below.

<Route Url="/Results/:queryID" Method="POST" Call="QueryResults"/>

What if I have to pass two parameters to QueryResults, how to do configure Url?

Something like Url="/Results/:queryID/:parameter2"   ?

Thanks.

I have a query text that I need to execute and return results as xml.

It may be an SQL query or an MDX query. Is there some easy way to determine which one is it?

Any ideas?

Hi all,

We faced a problem where we would like to map a $lb object to its corresponding data model structure in order to later on export it as JSON.

So imagin that we have something like this that actually maps to a persistent table with its structure. 

$lb("",,,,,"",,,"BOOLEAN","0",2,2,"1",,"bla",$lb(,,"bla","20050502123400"),"",1,"bla",,0)

Is there a way to transform this $lb (without the need of openig the object itself) to a JSON object with the proper table fields as properties?

Many thanks

I wanted to know if there was a way to dynamic set a target in the rule send command. I have a assign property that uses the lookup table that I wanted return the name of the target value and then set the target to that property . When I set the target= _@tDestination there is a parser error.

Hy.

I set up cache in container, which is working fine. But when accessing managment portal the default user was alway Unknown user and no username or password were required. So i disabled the Unknow user in the Security section, but now i keep getting an error access denid. 

Hi!

I have a global-mapped class that I want to add a transient property through (or at least, not stored on the database). This property is the sum total of various charge classes that are linked to the class via child relationships.

I want this new transient property to be visible at least via SQL.

My current approach is to total it up in a ClassMethod called via SqlComputeCode. It seems to work, but feels clunky. I wonder if there is a way without passing the %%ID through? I tried it with $this but that only returns the object name in a ClassMethod. I think it has to be a ClassMethod if called

Greetings,

How do I organize a wildcard search with respect to a database search?

Example of what I am trying to do:  s x=$o(^G("ABC","A*",x))

Trying to navigate through the ^G global for all occurrences of "ABC", and "A*" ("A"+wildcard) but I am new to M and don't know positively how to do this.  Perhaps I don't use an "*" at all, rather; another convention altogether.

Please advise.

Thanks in advance for everyone's assistance.

Hi everyone,

I have a project which requires the sending of JSON messages to an external service provider using REST. The service provider requires the message contents to be signed.

Their instructions:

1. Add a header called "Date" with the the date and time in a specific format - done
2. Add the client's certificate password in a field in the header - done
3. Create a string which consist of the {Date}{newline}{Password}{newline}{etc}{Message Body}.
   1. Convert to a UTF8 byte array
   2. SHA256 sign the value with the certificate and private key and use RSA PSS padding
   3. Base 64 Encode the value and place it in a Signat

Hi, Community!

And so I continue with publishing of the tasks for the Final round of InterSystems Contest on InterSystems Caché and DeepSee as a part of IT Planet Student Championship in Sochi. This year we had about 2 000 participants in InterSystems Contest.

One of the tasks for the finals was to crack the black box and another to output 9876543210!

Here's the next task: gravity!

Hopefully a simple question.

Using the Rule Editor, I can open a routing rule and easily define an 'effectiveBegin' and 'effectiveEnd' date.  I want to utilize this date feature for a "sub-rule" (i.e. rule #1) but not the entire routing rule therefore impacting all other rules. I also do not want to split and create a brand new routine rule just to send the message to the target business process.  It would be ideal to keep it contained within this single routing class that was created.

In "Rule Set #1", is it possible to have a "Rule #1" defined that can either use a 'send' action or 'delegate'

Greetings, can someone give me some help? I'm trying to use job for a instance method, as it's described here but...
Anyway, I have a method like this:

Method PrepareInstance(path){set ..Tool = ##class(Tool).%New(path)do $System.Event.Signal($zparent)}

That is being called like this:

Method TestPurge() As %Status{job ..PrepareInstance(..GetTestDirectory("../fixtures/_/dummy-project"))::10set msg = $System.Event.Wait("",10)
}

But it fails because:

<METHOD DOES NOT EXIST>zTestPurge+1^UnitTest.Tool.1 *PrepareInstance

Am I missing something or is that a bug?

HI Community,

I do have a table with quite some names written in Uppercase:

To simply correct this, I have created a button with some code behind it.:

ClientMethod convertToTitle() [ Language = javascript ]
{
    
    var ctrl = zen('Relation');
tVar = ctrl.getValue();
     
tVar = this.StringConvert(tVar)
    zenPage.getComponentById('Relation').setValue(tVar)
}
ClientMethod StringConvert(str) [ Language = javascript ]
{
    ///alert (str)
    str = str.substring(0,1).toLowerCase() + tVar.substring(1).toLowerCase();
    ///alert (str)
    var pieces = str.split(" ");
    for ( var i = 0; i < pieces.length; i+

In this article, I'd demonstrate how you can visualize the usage of Ensemble Workflow with DeepSee (tested on 2015.1 and later).

How can I localize arbitrary column name in DeepSee pivot?

If a column name is a dimension or a measure I can localize using architect following this guide.

But what about some random string?

I have tried setting:

• Value
• $$$Value
• $$$Value/MYDOMAIN

as a Caption, but every option simply displays as is.

Ensemble 2015.  Working on an a way to send NACK'd HL7 messages to a flat file for external review/troubleshooting. (Similar to the way BadMessageHandler deals with validation errors.)

I think I have the Alert piece down, but need assistance with the exact syntax to do an SQL query in the DTL (or a custom function) to pull the HL7 message Raw Content into the Alert, based on the SessionID.

(Also, anything special to write alerts to the File Operation?)

Thanks,  Brian

I am working with Caché Relationships.

I know how to iterate through the One side of the relationship and for each One iterate through all the various Manys.

What I have been trying to figure out, is the code (I can put into a Class) that will start at the top of the Manys, iterate down and for each of the Manys, pull the associated One.

I can do this with SQL or Globals, but I want to use only Class type code.

Is that clear? Any help?
