NewBie's Corner Session 11 Routine Line Types and Gotos

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

InterSystems Caché provides a GUI (Graphical User Interface) based Integrated Development Environment (IDE) called Caché Studio. Developers can use Studio to create and maintain applications.

In this session we will cover Routine Line types; which are Label lines, Executable code lines and the Routine Header line as well as Gotos.

Hi. This about  a migration of code from a DEV environment to a PROD environment.

If an (under development) business host is Enabled in DEV environment  and the production class is migrated across environments, this means that the Enabled status of the same business host in PROD would also become enabled (even if it may have been disabled before the update)

I want to migrate the production class, but leave the enabled/disabled status of business hosts the same - so - i make a list of them, upgrade - then go through each one resetting their status to the original setting using Ens.Director.

Hello Community,

I am trying to create a simple Ensemble DTL transform using the GUI.  In order to test something very simple, I have created a transform that does nothing.  

I'm using test data from here: https://www.emedny.org/HIPAA/5010/5010_sample_files/835%20Sample%20(Ins…

 It's a very small test 835 file.

My transform looks like this in the compiled class:

<transform sourceClass='EnsLib.EDI.X12.Document' targetClass='EnsLib.EDI.X12.Document' sourceDocType='HIPAA_5010:835' targetDocType='HIPAA_5010:835' create='copy' language='objectscript' >
<if condition=

I am writing a static SOAP response to simply test connectivity. The end users is getting an error "Message: The processing instruction target matching [xX][mM][lL] is not allowed.", which I believe is related to white space. if I observe the response, it looks like there are two blank lines between the header and the body, which I'm guessing is the white space problem. But I can't seem to get rid of it.

Any ideas?

Code:

<script language="Cache" method="OnPreHTTP" arguments="" returntype="%Boolean">
     Set %response.ContentType = "text/xml"
    Quit 1</script>
<?xml version="1.0"

Hi,

Does anyone have a sample that demonstrates how to use the Data Transformation option create='existing', in order to update an existing object by its ID?  My use-case is that I have an HL7 message coming in which contains data on a patient that may or may not already exist in a (non-HL7) table.  I want to use the PatientID from the (source) HL7 message, check if that patient exists in the (target) object, and if so, insert some new data into the existing patient, or if not, create a new patient.

I believe that to use create='existing', I need to provide the DTL with the PatientID as a

InterSystems has corrected a defect with Mirroring that can impact data integrity

The defect is present in all released versions Caché, Ensemble, and HealthShare beginning with 2015.2.0. It is present for all platforms and affects both failover and asynchronous mirroring configurations.

I am trying to find the presentation for the User Group Sessions that were given at Global Summit last week. In particular the Healthshare Provider Directory presentation, so I can share the ideas with others at my organization. Does anyone know where I can find those? I am not seeing them under the Global Summit tag.

Thanks

First post!  In order to somewhat redeem myself for an unnecessary call to support,  I've decided to post some classes that I've written to monitor certain metrics inside our Ensemble Live instance (yeah, Kyle, you WERE laughing at me, but it's okay). What the classes do is to run queries and code to get database sizes, status of the mirror, counts of rows in tables such as EnsLib.HL7.Message and Ens.MessageHeader. The data is collected and written to tables and then an email is sent out daily upon completion. I've found this quite useful in keeping an eye on what's going on.

I need to pass an equivalent of .Net Dictionary<string, int> instance from .Net to Caché. In the application, the Caché .Net provider has been used so far, so we came up with passing it as an instance of array of data types. However, the only way to fill the array we are aware of is to use its Add() method which invokes a call to the server instance method of the array for every key-value pair inserted.

Is there any way to fill the array at once - inserting all the pairs in one server call? Alternatively, is their any other .Net (Provider or eXTreme) API we can use for this task?

I know that

We have multiple implementations spanning many namespaces and edges.  I would like to see if I could identify a single place, perhaps on HSREGISTRY or HSBUS, that I could capture certain events like searches (from all customers) and record transfers (with requester and provider).  

The goal is to have a dashboard that would show simple stats such as searches by participant, records shared by participant and records consumed by participant.  These are the 3 most important.

I appreciated the feedback on the other question of "how" but now I'm hoping to find the "Where".  

Hi,

I'm trying to perform a SELECT with parameters using the EnsLib.SQL.OutboundAdapter. The SELECT returns results but seems to discard the parameters I try to send. I have tried two methods.

First:

Set par(1) = "20160630"
Set par(1,"SqlType") = 12
Set sql = "SELECT Cod, Ing, score FROM [bbdd].[dbo].[vw_Test] WHERE MyParam >= '?'"
Set tSC = ..Adapter.ExecuteQueryParmArray(.QueryResultSet,sql,.par)

Second:

Set par(1) = "20160630"
Set par(1,"SqlType") = 12
Set sql = "SELECT Cod, Ing, score FROM [bbdd].[dbo].[vw_Test] WHERE MyParam >= '?'"
Set tSC = ..Adapter.ExecuteQuery(.QueryResultSet,sql,par)

Although

This is a cross-post so remove if i'm breaking a rule, i just wasn't sure if i was posting to the right place. I've been to the globalsdb website and it doesn't look like i'm going to get much help from there.  

NewBie's Corner Session 8 Not

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Click on the Caché Cube in your system tray and select Terminal to try out these commands.

NOT operator ('), single quote or apostrophe 

The "NOT" operator reverses the truth-value and is intended for numeric operands, however it can be used on alphanumeric operands.

Set X=1

Write  'X

0

Set X=1

If X Write "True"                               ; 1 is always true and 0 is always false

True

Set X=0

Write 'X                                                ; X is 0, so "Not X" is 1 or true

1

I am trying to write this loop as efficient as possible.  The global has over 10 million records.

SET PIDX=""    
For
 { 
              Set PIDX=$ORDER(^[Nspace]LAB(PIDX))
              Quit:PIDX=""  
              Set Data=$GET(^[Nspace]LAB(PIDX))
              Set BBData=$P(Data,"\",6)
              If BBData'=""
              {
              If BBData'="########"
              {

Am I better off not setting the variable BBData and using If $P(Data,"\",6)'=""

Also, is there a better way to write the two If statements in one line so it only continues if it is either "" or ########

 I try going to http://www.globalsdb.org  not much help there. I'm wanting to use this for a personal project of mine,  if needed i can go to GT.M I just haven't used a linux machine in quite some time and i was hoping to hit the ground running. Any help is appreciated.

Hi,

Is there system wide or cube wide setting can turn off the deepsee query cache, or force query to compute without using cache ?

Many thanks in adavance.

Hello!

In Caché there is a way to print all current variables using write command without arguments:

But is there a way to get a list of this variables? I am looking for something that would return value like $LB("Einstein", "Mozart") for this case.

Thanks!

I want to show my script which I use for a completion in bash, for ccontrol and csession. 

With this script bash helps to available (running or down) instances to ccontrol, or in csession

I am trying to calculate a dimension percentage for WFRole on a child cube named MbMRouteHistoryInitiatorObj joined to a parent cube named MbmQaSObj by using a calculated member dimension within MbmQaSObj. 

If I use the calculated member dimension value expression of [WFRole].[H1].[WFRole].CurrentMember/ [WFRole].[All WFRole].%ALL in the child cube MbMRouteHistoryInitiatorObj, the percentages work correctly.

I am not able to calculate the same percentage using the value expression [MbmRouteHistoryInitiatorObj].[WFRole].[H1].[WFRole].CurrentMember/ [MbmRouteHistoryInitiatorObj].[WFRole].[All

Hi, after installed Healthshare 2015.2, all the tables previously correctly listed working with Healtshare 2014.1 are NOT listed anymore. TrakCare tables are not listed in the catalogue, nor by the WinSQL Intellisense.

Hello guys,

I've built a simple rule , as follows:

Thing is, in rule 2, the operation succeeds, the message reachs BO HL7, but in rule 1 it does not go through. In rule 1, I have two different conditions, but they are linked by an OR and one of the conditions is simply IF 1=1.

Do you guys have any clue on why rule 1 does not reach BO HL7?

Thanks

Hi!

Here is the question in Russian Forum regarding roots extracting.

In Caché ObjectScript we use exponentiation operator (**) to raise an exponent to power. F.e. let's raise 3 to power of 3: 

USER> write 3**3 

27

And we use the same operator to extract the root. 

USER> write 27**(1/3) 

2.999999999999999963

And 2.999999999999999963 is not 3, obviously.

How to extract roots properly in Caché ObjectScript?

Long story short, I created some test data, then deleted it. The database (cache.dat) is 67 GB in size (was around 1 GB before tests).

How do I compact that?

In the HL7 Annotations available in the Management Portal,  at the message type and message structure levels, there are columns for 'Explicit Usage' and 'Implicit Usage'.  In nearly all cases, the values in these two columns match, but at least for message types RAS and RGR, they don't.

What's the meaning of explicit and implicit in the annotations?

Thanks,
Liz

Earlier in this series, we've presented four different demo applications for iKnow, illustrating how its unique bottom-up approach allows users to explore the concepts and context of their unstructured data and then leverage these insights to implement real-world use cases. We started small and simple with core exploration through the Knowledge Portal, then organized our records according to content with the Set Analysis Demo, organized our domain knowledge using the Dictionary Builder Demo and finally build complex rules to extract nontrivial patterns from text with the Rules Builder Demo.

This time, we'll dive into a different area of the iKnow feature set: iFind. Where iKnow's core APIs are all about exploration and leveraging those results programmatically in applications and analytics, iFind is focused specifically on search scenarios in a pure SQL context. We'll be presenting a simple search portal implemented in Zen that showcases iFind's main features.

I have a MySQL server with "posts" table.

I also have a Caché server with "downloadedposts" table. 

They are connected from Caché to MySQL via SQL Gateway

I want to keep Caché table synced with MySQL one  (MySQL "posts" table is a master copy), so periodically Caché queries MySQL server and downloads data. So far so good, and if a record appears or changes in MySQL table, Caché downloads the changes.

The problem I'm encountering is that sometimes rows would be deleted from  MySQL "posts" table.

How do I synchronize deletions?
