I need another set of eyes to look at the following. Instead of a Data Lookup table, I wanted to try to lookup a value against a Cache table that I had build. So I thought I could write a function to run a simple SQL query against the Cache Table and return me a %Boolean value back to my routing rule. However today I found that it was not working properly.

Can someone take a look at the following method and verify that I am doing this correct?

index = column name

value  = HL7 field that I am passing into the method

I have a case where I need to look up the NPI provider against an External MS SQL database to retrieve our Provider Identifier to send to a downstream system. In the past I would use a Business Process (BPL) to connect to the outside MS SQL via JDBC and get that information for me. But I was thinking instead of creating a BPL process to do this, would it be better just to link to the outside MS SQL database table to retrieve the information in a SQL statement within a DTL?

Languages like Java and C++ allows to develop a multi-threaded program with two or more parts that can run concurrently and each part can handle a different task at the same time making optimal use of the available resources specially when your computer has multiple CPUs. Is it possible In ObjectScript? If yes, Where I can get a good sample or application?

We are trying to convert some of our SQL Service Integration Service jobs from Visual Studio to Ensemble. If we execute a Stored Procedure within SQL Server Management Studio it is returning approx 12,000 rows. However when Ensemble executes the same Stored Procedure it is only returning 250 rows.

Is there a limitation to EnsLib.SQL.Snapshot?

This is how we are calling the Stored procedure

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.

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,


Florian Hansmann

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 am getting the date 20201121090000 in the HL7 message, How do I convert it to 2020-11-21 09:00:00 in a easy way?

I am currently doing it by extracting the first 7 values and splitting as date and time and then adding a hyphen using substring.

Is there an easier way by using $ZDATE? or something like that?

I'm processing POP3 emails using the standard EnsLib.EMail.InboundAdapter adapter and %Net.MailMessage. I'm basically processing documents that are attached to received emails. This works fine if the document is simply attached to the email itself. But some systems are sending documents that are attached to an attached email which has content-type = message/rfc822.

How do I get the attached file from the attached email?

In Cache WIndows environment:

Trying to use the $SYSTEM.SQL.DDLImport to import XML File that has ClassMethods, no SQL Table, but it doesn't appear to be working. I can use this ClassMethod to create SQL Tables. The manual method I have been using is to go into Cache Management Portal, Classes, Import.

I create an XML file first, then run the following to import but get no errors. Any ideas?

I need to read a UTF8 encoded text file and translate the content to 8-bit.

Using %File class and $ZCVT(TXT,"I","UTF8") works , but I see that if the content is larger than max string  (32000) and we cut the content

To max string chunks, we can get a <translate> error if we cut it in the "wrong" point..

Is there a better way to do this task?

My code looks like this:

I noticed when creating Record Map's within Ensemble that it is creating a Persistent cache table as it translates the file and puts it into the Record Map data structure.

I was wondering if there was a way to add a column to the cache table that is Hidden from the record map, but is a calculated date value on when that record was inserted?

I want to call some Java Remote Call through Java gateway.  The call code as following:

class CallRemote Extends %CSP.REST {

Method Index() as %Status {


      set gw = createJavaGateway()

     Do callJavaMethod(gw)

     do gw.%Disconnect()

Catch {




But Every call need connect to Java Gateway and disconnect it. But It's cost too high( about 80ms)

So, According to my Java experences, I need create some connection and put it into global static ConnectionPool

Indices Not Working

Forgive my lack of understanding, but I am working on a vendor created Cache database and the indexes specified in the classes for ODBC connections are not working. A few of them are created, but of the 50+ classes we have, only a handful of them are created when the class is compiled, yet no errors occur.

Example 1:

Hi guys!!

In the system that I work, I came across an iterator pattern that uses the %Resultset library without performing the close after executing the query. Does anyone know how to say what are the impacts of not performing such a procedure?

If you have any model of iterator pattern made in caché to recommend as a good example, I will be grateful hehe  :D

Date Filtering Functionality

I have come across several cases where I need to set a Date filter to send only send any admit/scheduled date past a certain point. We have a couple different date comparison functions but none looking at the true date. Most of them are date + 15 or etc. Does anyone have a good date function they have written to say if x > 20170102 ?

I was able to define ECP connection in Installer class that I run when I build docker image for my Docker IRIS application. Now I start to use Amazon ECS and Autoscaling. When a new instance is created and it runs the IRIS container, I want it to "register" as an Application server on the remote database server. What code can I execute to add an ip address as an Application Server?

I have a list of 300 code combinations in the following format, which I plan to load into a global

X123, Internal health

X234, external health

X345, Peripheral health etc..

I want to get the code from the DG1 segment, compare to the global, and add a description. Is there an easy way to do it?

So in my DG1 segment If I get the code X123, what I want to do is check if the code is in the global and if it does add the description in the field.

So DG1 will look like this:
