Question Scott Beeson · Feb 16, 2016

Here is my original query:

SELECT EventType, InitiatedAt, COUNT(*) as cnt
FROM HS_IHE_ATNA_Repository.Aggregation
WHERE EventType = 'LOGIN'
AND LocalDateTime > '2016-02-16 11:00:00'
GROUP BY EventType, InitiatedAt

This gives me data like this:

LOGIN %SYSTEM 69918
LOGIN OTHER 39


However, I need to get the data back as two columns with all but the last concatenated and delimited, more like this:

LOGIN;%SYSTEM 69918
LOGIN;OTHER 39

 

I tried this:

SELECT EventType + ';' + InitiatedAt as k, COUNT(*) as cnt
FROM HS_IHE_ATNA_Repository.

Question Eduard Lebedyuk · May 24, 2017

I'm aware of two ways to get list of files in a dir:

set dir = "C:\temp\"
set rs = ##class(%File).FileSetFunc(dir, , , 1)
do rs.%Display()

and:

set dir = "C:\temp\"
set file=$ZSEARCH(dir_"*")
while file'="" {
   write !,file
   set file=$ZSEARCH("")
}

Yet they bot return only files and directories in a current directory, but not files in subdirectories.

I suppose I call one of these recursively, but maybe there's a better solution?

Question Peter Steiwer · Dec 12, 2016

Is there a better way to iterate through all properties of an object than the following? Perhaps without needing to open a definition of the class but directly against the object?


SAMPLES>set t=##class(HoleFoods.Transaction).%OpenId(1)                          
SAMPLES>set def=##class(%Dictionary.ClassDefinition).%OpenId("HoleFoods.Transaction")
SAMPLES>for i=1:1:def.Properties.Count() {  w def.Properties.GetAt(i).Name_":"_$property(t,def.Properties.GetAt(i).Name),!  }
Actual:0

Question Josh Barney · Mar 24, 2016

I believe the I have followed the instructions to attach a document to the body of a post request but nothing is being sent out in the files{} port of the request.  I can either get the stream in "data", not visible at all, or visible but no form data. Any help would be appreciated, below is what I have:

ClassMethod SendFax(phone As %Stringcoverpath As %Stringdocpath As %StringAs %String
{
     Set req ##class(%Net.HttpRequest).%New()
    //test server
    Set req.Server "httpbin.org"
    Set req.SSLConfiguration "CardChoice"
    
    Do req.InsertFormData("Username",##class(HData.

Question Larry Pinsky · Feb 28, 2020

I have a code block in a BPL.  I have the below SQL and code.  All variables have been declared and set.  When I run the SQL, if there are no values returned, I get 100 for the value of SQLCODE when I perform the FETCH, which is correct.  If values are returned, I get a -400 error when I perform the first FETCH.  I've investigated, but cannot find the reason for a -400 error.  Hoping someone out here understands this and knows what's wrong.


   &sql(DECLARE D1 CURSOR FOR SELECT A.SHIPMENTTRACKINGNO, A.SERIALNO, A.CDWACCNO, A.CDWINVOICENO, A.CDWORDERNO, A.CDWPARTNO INTO :context.

Hello, first of all thanks for your time reading our question 💭

 

We would need to be able to transform a hexadecimal string to a base64 coded one. 🔄

To be specific, our use case is this:

1º We have our hexadecimal as follows:

4C5803040101020179C3913EC3BA7C4C580708010101021824584D4C

2º We convert it to ASCII:

LXyÑ>ú|LX$XML

 

using this online tool:

https://www.binaryhexconverter.com/hex-to-ascii-text-converter

3º Then we should be able to translate the ASCII to base64:

TFgDBAEBAgF5wyYjMTQ1Oz7DunxMWAcIAQEBAhgkWE1M

 

We are being helped by this useful web:

Question Marc Mundt · Jun 21, 2016

A customer is using Caché online backups and needs to automatically purge the cbk files with a scheduled task.

This is a wheel has been reinvented uncountable times already and I know somebody out there has a well written, extremely robust version that has already stood the test of time.

Does anyone have a nice routine/class/task for purging old Caché backup files?

Hello.

For debugging purposes I  sometimes need to display stack information to the current device or save it (to a global for example).

There is this snippet offered in documentation:

ClassMethod StackToDisplay()
{
    For loop = 0:1:$Stack(-1) {
        Write !, "Context level:", loop, ?25, "Context type: ", $Stack(loop)
        Write !, ?5, "Current place: ", $Stack(loop, "PLACE")
        Write !, ?5, "Current source: ", $Stack(loop, "MCODE")
        Write !

Question Timothy Leavitt · Jul 8, 2016

I've been trying to write a method to compare two local variables, which may be arrays, for "equality" - that is, to see if they have all the same subscripts (if they're arrays) and values. This is the best I've come up with so far - are there any better/simpler approaches out there?

/// Returns true if arrays <var>first</var> and <var>second</var> have all the same subscripts and all
/// the same values at those subscripts.

Question Alexander Koblov · Feb 5, 2016

Hi.

It is easy to receive JSON representation or dynamic Array from %ListOfDataTypes:

set l=##class(%ListOfDataTypes).%New()
do l.Insert("a")
do l.Insert("b")
do l.Insert("c")

set arrStr=l.$toJSON()
zwrite arrStr
set arr=l.$compose([])
zwrite arr

How to make backward conversion? How to receive %ListOfDataTypes from dynamic Array an JSON string?

I've tried

SAMPLES>set list = ##class(%ListOfDataTypes).$fromJSON("[""a"",""b"",""c""]")

%FromObject+21^%Library.RegisteredObject.1 *%Exception.General Compose Compose %FromObject Unable to map from %Library.Array instance to %Library.

Question Daniel Kutac · Apr 30, 2019

Hello,

I have a very simple web service that I'd like to secure via SAML Authorization with X.509 Certificates. I am, however struggling with documentation and my lack of cryptographic skills. (I do this just for educational purposes now, but need to use it in the future)

Does anyone have an example that shows how to construct a SOAP Client with adding all necessary security headers manually or point me to a decent learning resource?

 

Thank you very much!

Question Justin Wilson · May 9, 2018

I have been tasked with creating a class that will handle error logging in a consistent manor for an application I am working on.  The need is to have all variables in the calling method logged along with some other information. 

The example given was zwrite which is exactly what I need, however, I somehow need to capture the output of ZW and put it into a database table.  Any easy way to capture this data?  I was able to dump ZW to a file, but that is not ideal.

Any help is appreciated!

Question Flávio Lúcio Naves Júnior · Oct 21, 2019

Hello Everyone,

I'm want to know, what is more common for your company to use, the abbreviation syntax or the complety name of commands, and why?

Ex. 

S VAR=10 / D FUNC^ROUTINE F 1:1:1000

Set VAR=10 / Do Func^Routine / For 1:1:1000

set var=10 / do func^routine / for 1:1:1000

Here in my company, we are familiar with the abbreviation syntax, because to spell is more faster.

Question Juliana Schallert · Jul 20, 2016

Hi,

I am new to Cache and I am trying to convert a JSON string (msgdata) that contains a JSON payload to an object to be saved into a Driver. Entity table.  I am running into 2 issues and would appreciate any help:

1) It seems that when the 1st element of a list within the payload (Choices) is an empty string, after I call %ConvertJSONToObject, the obj.%data("payload").Choices contains just 1 empty element, removing the next 3 valid values (10,20,30). The same does not happen if I change the input to [10,20,"",30], in this case it works correctly.

Question Yone Moreno · Jan 28, 2021

Hello,

We would need some help,

Our aim is to send an image as binary data using a REST Service

Currently we do the following:

1 We get from the external system a binary image in our REST Operation

2 We encode it to Base64

set linea=""
    while (tResponse.Data.AtEnd = 0) {
        set linea = linea_$system.Encryption.Base64Encode(tResponse.Data.Read(57))
    }

3 We send it to the Process in a Response Message:

Class Mensajes.Response.miSCS.ConsultarImagen Extends Ens.Response
{

Property resultado As %Boolean;

Property informacion As %String(MAXLEN = "");

Property binario As %Stream.

Question Scott Roth · Jan 13, 2021

I have a case where our EMR is sending data, but not all the values needed for the Ancillary are valued properly and causes that message to error/halt processing on the Ancillary system, not ideal but its what they do. I would expect them to still process the message except that 1 field, but they don't.

I want to add validation to make sure certain fields are valued correctly for the Vendor. 

So I add some statements to take those items that don't pass this validation out to a batch file with headers.

But I want to email out that batch file.

Question Evgeny Shvarov · May 26, 2017

Hi!

I'm saving object instance using RestForms.

RESTFormsUI calls %Save() for me, which is great. But I want to set the property CreationDate with the current date for every new record being inserted.

So  object callback implementation seems as a reasonable option. I did the following:

Method %OnBeforeSave(insert as %Boolean) As %Status [ Private, ServerOnly = 1 ] 
{

 if insert s ..CreationDate=$H

 q $$$OK

}

And it works fine.

But Documentation says I'd better use %OnAddToSaveSet()

What are you using for the callbacks in similar cases?

Hello,

We would like some advice

We have developed a REST Operation

The code is:

Class Operaciones.REST.miSCS.miSCS Extends EnsLib.REST.Operation

Method SubirImagen(pRequest As Mensajes.Request.miSCS.SubirImagen, pResponse As Mensajes.Response.miSCS.SubirImagen) As %Library.Status
{
    set httpRequest = ##class(%Net.HttpRequest).%New()
    set tResponse = ##class(%Net.HttpResponse).%New()
    //set httpRequest.ContentType = "application/json"
    set httpRequest.

Question Yone Moreno · Nov 22, 2023

Hello,

First of all thanks for your help.

We have the following scenario: some responses include special characters as ">" and "<" which are being put inside a property defined as:

Property PACPROBLEMAS As %String(MAXLEN = "", XMLNAME = "PAC_PROBLEMAS");

 

So then, when we observe the LOG SOAP it shows that the Target System replies to the ESB as follows:

➡️ <PAC_PROBLEMAS>46807#278.

Question Jordan Simpson · Aug 19, 2021

Hello,

When using GetFieldStreamRaw(), by passing in a variable instead of using an output for the Remainder, will this affect how it is stored into a segment in a cloned message? I know it would usually output the remaining fields of the segment but in order to conform to a supplier's spec, they'd require "^^PDF" rather than the rest of the segment. Because the segment becomes immutable, the code below seems to be the way to do it.
