Question Blaise ZARKA · Dec 19, 2019

Hi,

On a persistent class, I have defined an %OnNew method that validate some properties with appropriate status code for each kind of error. Question is: how do you catch the specific error when %New is called on this class?

Surrounding %New method with a try-catch not seems to work.

Thanks

I'm trying to tie IRIS (2019.1) into our Concord Fax cloud-based email-to-fax workflow. We have some sites that require a fax be sent to multiple locations based upon certain data (ie Radiology and Emergency departments). Unfortunately, CC-ing does not work with Concord Fax so I need a way to send the email, change the recipient, and then send it again if certain criteria are met. Is this possible? Do I need to duplicate and rename the method, calling the second one in the MessageMap?

Here's what my code currently looks like:

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

Hi Developers!

Many of you are looking for samples on how to work with InterSystems IRIS Analytics, formerly known as DeepSee.

There is a Samples BI module with Patients and Holefoods examples which is available on Github with source code. The installation steps are clear but take time. 

Recently we added the option to run IRIS Community Edition containers with ObjectScript Package Manager (ZPM) on board. This simplifies the installation to the "run-one-command" step for the modules submitted to ZPM Community Registry. And thus we can benefit the Samples BI installation with ZPM.

And here is how you can run it on your laptop.  Let's go!

This is a lesson learned, which I would like to share with community.  


Recently I ran into an issue, where I was using %ConstructClone and it kept cloning extra records, which were not needed.  The record for which I was trying to run a clone had many-to-one relationships.  

The solution to this issue was using param -1.  If you run %ConstructClone(-1) it will not clone relationships, but rather just clone single oref as desired in this case.


I hope this information helps someone who is working with similar records.

Hi Developers!

Often when we install a code package we want to make some post-install settings, e.g. call to a method, set up a configuration file.

This article describes how to do this with the ObjectScript Package Manager.

To make any post-install calls you need to add <Invoke> elements into <Invokes> tag to the module.xml. Each <Invoke> element can have nested <Arg> elements if you want to pass params to the method:

<Invokes>

<Invoke Class="Class.Name1" Method="MethodName1">

<Arg>Sting Value</Arg>

<Arg>123</Arg>
</Invoke>

</Invkoes>

Question Scott Roth · Jan 10, 2020

I am working on a BPL to take data from a MS SQL database and create an HL7 Materials Message for our EMR.  I have done this plenty of times in the past however I am running into an error.

"Remote Gateway Error: JDBC Gateway SP execute(0) error 0: Access to the remote server is denied because no login-mapping exists."

What is confusing is that this BPL doesn't differ from any of my other BPLs in connecting to MS SQL Server. I know I am missing something..

This BPL will execute the 1st Stored Procedure without any issues, the issue is when it comes to executing the second stored procedure.

Question Jorge de la Garza · Jan 9, 2020

I have an array of table names that I want to iterate over and for each table, get the number of rows.  I was hoping I could do something like:

set tStatement = ##class(%SQL.Statement).%New()set tSC = tStatement.%Prepare("SELECT COUNT(*) AS ObservedRowCount FROM ?")$$$ThrowOnError(tSC)set tTableName = ""for{  set tTableName = $O(tCounterAry(tTableName))  quit:tTableName=""set tResult = tStatement.%Execute(tTableName)
  // ...
}

But that doesn't work:

ERROR #5540: SQLCODE: -1 Message:  IDENTIFIER expected, ? found^ SELECT COUNT ( * ) AS ObservedRowCount FROM ?

Have you ever needed a math function but could not find what you needed and ended up writing your own? Look no further! ObjectScript-Math is here to solve all your math related function needs.

ObjectScript-Math is an Open Source library for ObjectScript Math functions. It is now available on Open Exchange. This library contains a mix of new functions that are not currently available and functions that are available. The existing functions will be wrapped for use from ObjectScript-Math so that all Math functions can have a central location.

This library will continue to grow, so give it a try and give your feedback!

Don't see what you are looking for? Please feel free to submit requests for additional functions or contribute code yourself!

I have a case where I have an external table that lives out in MS SQL. Using Ensemble Security functions has anyone created a csp or cls page that acts like a portal to allow users to Update a multidimensional table without knowing SQL? I could clone the EnsPortal.LookupSettings but that was made for LUT which are only 2 columns.

I know its a long shot but trying to see if there was anything off the shelf that I can use to help meet the requirements of this project.

Question Jude Mukkadayil · Dec 11, 2019

Hi,

     I have written a procedure with the help of object scripting to export data to a csv file. There is more data than  the csv limit.

Can anyone please tell me how to get the row count of csv file using object scripting, so that I can write an if condition and write to a second csv file.

Please find the code writing to the csv given below.

while (ind '= ""){
set row = ^CacheTemp(repid,"MAIN",ind)
use filemain write row,!
; Get next row index for MAIN report
set ind = $order(^CacheTemp(repid,"MAIN",ind))
}close filemain
}

Thanks

Jude

Hi everyone,

I've encountered this annoying issue so many times before, if any one also encounter this issue, please share here if you have any solution.

So, I've been working on a web service project using HealthShare 2015. Sometimes I have to set a debug target to a csp file to debug it. If I pause the debug process about 3 minutes above or so (to examine an object, variable, etc..) the studio will hang.

Hi Developers!

Often we need to use relatively small arrays with constants, static arrays in algorithms, etc where we need to do something with each element of an array. There are several ways to deal with it in ObjectSctipt. 

Previously I used to use globals, locals, PPG for this but not so long time ago figured out that %List is a way too handy.

Indeed, suppose we have an array of months and need to set up and use it in our code.

Question Ben Spead · Dec 21, 2019

Does anyone know of an API that will do a hostname look-up based on IP?  We could of course use call-out but the format of the results vary based on OS and if there is already an ObjectScript tool which will parse this then we'd rather use what is already available.

Thanks!

Hi All,

I trying to get the DisplayList data of the ValueLIst from Java using Springboot. when I try to get the DislayList data via java code but I'm getting the VALUELIST data. I don't get any idea to get that DisplayList data. Below is the example

Property PetName As %Integer(DISPLAYLIST = ",Cat,Dog,Dove,Parrot", VALUELIST = ",1,2,3,4");

Java Code:

public String PetName;

public List<Pet> getPet() {
        return ser.findAll();
    }

List<Pet> arrayList = getPet();
        for (Patient list : arrayList) {

Hello, InterSystems community!

Lately, you have probably heard of the new InterSystems Package Manager  - ZPM. If you're familiar with it or with such package managers as NPM, Dep, pip/PyPI, etc. or just know what is it all about -- this question is for you! The question I want to arise is actually a system design question, or, in other words, "how should ZPM implement it".

I've been having a blast with the Advent of Code puzzles this year - though I'll be heading into a busy span of time with family soon and will probably drop off toward the end. (At least, that's what always seems to happen - it's a good thing, though!)

I had a whole plane ride to play around with Day 13 and wanted to share some fun terminal tricks. I'm not planning to post my solutions on GitHub until the end of the year, but this is just visualization fun - not relevant to solving your own puzzle input (although visualization definitely helps for debugging) wink

ObjectScript has at least three ways of handling errors (status codes, exceptions, SQLCODE, etc.). Most of the system code uses statuses but exceptions are easier to handle for a number of reasons. Working with legacy code you spend some time translating between the different techniques. I use these snippets a lot for reference. Hopefully they're useful to others as well.
