Hi,

I seem to be able to execute sqlproc using the convention defined here https://docs.intersystems.com/latest/csp/docbook/Doc.View.cls?KEY=GSQL_q... provided the package/folder is a single level. As, soon I have a nested folder structure I get an error while trying to execute this. 

For instance, 

select id, Utils.Users_getRole(id) roles from users.users

works fine while,

Hi

 

I would like to create a new message of a particular type and append various segments programmatically.  I have started with the following snippet.  What I am currently finding difficult is to define a segment of a particular segment structure.  I would like to append a pid segment of 2.3.1 to my message.  I know I could you the importfromstring but I wanted to know whether there was a better way of achieving this.

i want to restrict certain IPs (ip for now and looking for more such parameters) from running my URL for security purposes...

i wanted to know how to access their ips and compare them with the list of restricted IPs, also if not IPs are there any other unique browser parameters which can be used for access control? and enhance security

Date range queries going too slow for you?  SQL Performance got you down?  I have one weird trick that might just help you out! (SQL Developers hate this!)*

If you have a class that records timestamps when the data is added, then that data will be in sequence with your IDKEY values - that is, TimeStamp< TimeStampif and only if ID1 < IDfor all IDs and TimeStamp values in table - then you can use this knowledge to increase performance for queries against TimeStamp ranges.  Consider the following table:

INSERT OR UPDATE SQL

Hi, I want to INSERT a customerID and customerName to a table if the customerID does not exist. Or UPDATE if they've changed their name.
I've reviewed the documentation (https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=RS...) and have confused myself with the INSERT OR UPDATE statement. Rather than using two individual statements , is there a way to get it in one?

What I have at the moment doesn't do anything. In fact it errors.

Hello,

We would like to learn how would you approach this task.

We would need to check every day a set of folders which are outside our server (in fact we could see them as if they were "inside" the server), then we need to check for modified or created files in the last day, and move all the ones which match the criteria to just one folder in our server.

 

We have thought about doing the following:

1) Create a task to run it each day:

Hello,

 

We would need to iterate all over the OBXs list and get their OBX3 CE1 to determine if it is the lab result we need to send to the output system.

 

We wonder how could we achieve this in a foreach component inside a Bussiness Process.

 

We think we would need to use a foreach because of it is needed to generate a message, for each one of the OBX which have the OBX3 CE1 that the output systems uses for the lab results.

Code sample to concatenate JSON arrays

ObjectScript doesn't include any built-in method for appending one JSON dynamic array to another. Here's a code snippet I use that's equivalent to the JavaScript concat() method.

Call it with any number of arguments to concatenate them into a new array. If an argument is a dynamic array, its elements will be added. Otherwise the argument itself will be added.

Semi-Persistent Classes and Tables

If you define a Persistent Class / Table the class compiler generates for you an appropriate Storage definition.
A different option is to define a SQL mapping for an already existing Global storage.  This has been excellently
explained already in a different series of articles.   The Art of Mapping Globals to Classes 1 of 3

Hi!

I believe the simplest is (to work with csv delimited by ";"):


set file = ##class(%File).%New( "data.csv" )
    set sc = file.Open( "R" ) 
    if $$$ISERR(sc) quit    ; or do smth

    while 'file.AtEnd {
        set str=file.ReadLine() 
        for i=1:1:$length( str, ";" ) {
            set id=$piece( str, ";" ,i ) 
            write !, id  // or do smth
        }
    }
    do file.Close()

Possible options:

different variants of error handling with sc code.

Embrace while loop into try/catch block.

And what's yours?

The attached code package provides a simple implementation of a web service client that utilizes the USPS Shipping API to normalize  an address.

This code requires the developer to obtain a USPS Shipping API user ID which can be obtained from the USPS shipping API website.  The assigned User Id can either be passed into the web service call as a parameter or can be coded as a parameter into the Request object.

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?

What if you could serialize/deserialize objects in whatever format: JSON, XML, CSV,...; attending different criteria: export/import some properties and not others, transform values in this or that way before exporting/importing,...; and all of this without having to change the class definition? Wouldn't that be great??

Well, perhaps it's a goal too ambitious to reach 100% but, exploring this idea, I've developed a bunch of classes that I thought it was good to share. If you want to test, change, modify or improve the code, or just take a look at it, you can do it here. There you'll find a more detailed explanation (see Readme.md)

Be aware, this is a proof of concept for myself done in spare times, sure it's not robust enough or it can be done much better... but, I was just playing...ok, I could just wait to the new JSON Adaptor (coming soon!) that sure is going to resolve much more scenarios in a cleaner way, but... meanwhile... :-) ...

SQLCODE Error -400

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.

This article will describe and include an example of how to embed an external PDF file into an HL7 segment, specifically ADT_A01:2.3.1 OBX().  This can be useful when attempting to insert pictures or other external data into an HL7 message.  In this example, the name of the PDF file to be embedded is provided in the incoming HL7 message in OBX(1):ObservationValue field.

cache 2017.2.1 (Build 801_3)

when I look into the "sql statements" ( sql page of the management portal ) I have lots of old statements with a lot of them frozen. many of them are %sqlcq routines (I believe these are the SLQ's I run when testing/running random SQL queries in the sql page. )

I can clearly see where I can click on an individual query and untick an individual query to unfreeze it. or delete it. but thats a painful slow process. I can't see anywhere to delete/change multiple queries

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.

Creating Portlets in DeepSee

What is a portlet?

The simple answer is: a custom widget. A portlet can exist by itself on a DeepSee dashboard, it can be used along side standard DeepSee widgets, or along side other portlets. The rendering of the custom widget is completely user defined. This means you can embed a web page, create a form to perform any sort of action needed based on the data on your dashboard, use third party charting libraries, or simply display data from outside of a DeepSee cube.
