#ObjectScript

I have a tablepane which uses Sql to get his data:

As you look at the ''Business" column i have to type a number (key Value) to get the [Fashion Retail] value.

How do I have to modify the Built WHERE clause in order to filter on name /description of  the Join Fields instead of the key value? I would like to filter on name/description rather than a key value. Some sample code is appreciated! Thanks in advance.

Dear Developer Community!

My name is Maks.

I developed DeclarativeCOS framework for declarative programming on COS.

Today I want to ask you about New Programming Language.

I have an idea to create new programming language which could be translated to COS classes / routines or even to int-files.

So, lets suppose it is happened. What do you want to see in such language?

Please feel free to say your minds. It is open discussion.

Currently, we are utilizing batch jobs at the OS level to kick off routines that watch for files. We are trying to convert these processes to be performed by the Task Manager.

The routines have while loops and perform while loops so long as the time parameters are being met.

What's the best way to ensure Task Manager kicks them off after the completion of the shutdown/backup/start process is performed, which we do nightly? I want to ensure that it starts it regardless of the time that we've set.

Hoping someone can help.

I need to convert a timestamp from the following format (YYYYMMDDhhmmss e.g. 20160105125915) to UTC time in the same format.

I presume I need to convert it to the system format ( like $HOROLOG ) and then use something like ConvertTimeStampToHorolog or perhaps LocalWithZTIMEZONEtoUTC but not sure of the syntax.

Thanks,

Conor

Hello everybody,
we would like to be able to analyze a rather complex software application, which has been programmed in “M” for a number of years by different developers, by means of a tool.
Our goal is to find a starting point for a code refactoring process. In the long run we would like to gradually eliminate the code growth points.
Does anyone know of a tool that can help us to do this?
So far, we have only found "RE / m" etc. by George James Software, but we do not yet know if these tools will help.

Your support and suggestions will be greatly appreciated. Thanks.

Hi all.

I have been using  a command pipe to open/run UNIX scripts for months without issue.  We recently installed the 2016 Caché Upgrade and now I'm getting the following error when opening the pipe:

<PROTECT> *OPEN[Q](|CPIPE|)

I assume some security or permission setting is to blame, but I'm not sure exactly what.  Here's the snippet of code...

s cpipename="|CPIPE|"
s filepath="/path/script"
​o cpipename:(filepath:"R"):10

Any feedback would be greatly appreciated!

Hello guys,

I was wondering whether there is another alternative to extracting a certain string out from a bigger one, rather than using the function $piece.

Maybe regular expressions? Another specific function?

Example:

Big string:

NAD+SLA+++TextIsHereNAD+SLA+++TextIsHere

String I want to extract:

TextIsHere

Function I'm already using:

w $piece("NAD+SLA+++TextIsHereNAD+SLA+++TextIsHere","NAD+SLA+++",2) > Will ouput TextIsHere
w $piece("NAD+SLA+++TextIsHereNAD+SLA+++TextIsHere","NAD+SLA+++",3) > Will ouput TextIsHere

Thanks!

Cache 2016.2.1

the system offers $LISTNEXT as a way of looping  in $LISTs and the documentation says this is much more efficeint than writing

for i=1:1:$LISTLENGTH(myList) { set value = $LIST (myList,i) }

I want to walk backwards in the list,

is there a $LISTPREVIOUS or do I have to use the followng syntax to achie

 for i=1:-1:$LISTLENGTH(myList)

So you have a namespace with thousands of .INT files and you want to identify routines that have not been executed in say the last 5 years. How would you do that without amending any existing software?

Introduction

Twilio is a great tool for programmatically initiating and managing phone calls. In this example we'll go over basic account setup, create a Cache Class to manage our interaction with the Twilio API, and initiate a phone call from the Cache Terminal.

The full Class used in this example is available on GitHub as well.

Setup

1. Create an account on twilio
2. Add a new phone number under the Manage Numbers Page.
   • This will be the number you call from.
3. Add a new caller ID under the Verified Caller IDs Page.
   • This will be the number you call to.

hi world, how can i have access to the BPL set rules in programming ?

for information: all logical rules are stored in routine data base, but i don't know how to have access to its corresponding name space.

thank you for helping

XDATA is used for a whole host of ISC libraries to store things like Zen pages, BPL logic and DTL transformations.

XDATA is the equivalent of XML config files of the JAVA world and JSON config files of the JavaScript / NPM world.

Whilst Atelier looks to shift source code to the disk, XDATA will remain a key component to source control our projects config / meta data.

I come across many developers who overlook XDATA, seeing it as an internal function of Cache and Ensemble and instead use globals to move meta data around, I've been there myself.

How do we need to set a flag with quit command and what is it share some example?

Is it possible to execute a sql update statement from objectscript? This code isn't working for me.

Set tSQL = "UPDATE table Set Status = 'Completed' WHERE ID in (1,2,3,4)"
Set tStatement = ##class(%SQL.Statement).%New()
Set tSC = tStatement.%Prepare(tSQL)

If I write my dynamic sql to the event log, copy and execute it in the Management Portal, it works fine.

These Globals are usually cleared out as part of the startup/shutdown processes. If your server never reboots how would you clean these out?

SOLVED

tl;dr how can you tell if a number is really a string

The original question has been updated/improved.

Equality comparisons on floating point numbers will produce different results...

"1.1"=1.1  //is true!

"0.1"=0.1  //is not true :(

This second comparison can be fixed with...

+"0.1"=+0.1 // is true!

The problem is, what if we don't realise that a value is a stringy number, or just overlook implementing this defensive check.

One solution would be to lint check %Float properties and return types that should originate from a number and not a string, as discussed here...

Is it possible to dynamically adjust the RetryInterval andFailureTimeout settings in a BPL?

I've got a business process that calls a web service operation to get a session ID from an external system.  There is a string property returned in the body of the response that indicate an exception occurred in the external system. I have code in the BPL that examines the property and sets the status property to an error status when that occurs.

Depending on what the value is I want to adjust the RetryInterval and FailureTimeout values used in by the system when the ReplyCodeActions is set to E=RD.

Good afternoon - 

I'm in the process of learning to make COS calls to REST-based web services and while I am having success, I'm struggling on how to parse out the results (I admit I'm very green at this):

Here's the code retrieving the JSON response:

w !,"Get the JSON"
Set Result = {}.%FromJSON(Request.HttpResponse.Data)

This has Result as a Library.DynamicObject.

I can then write out the response using:

w !,Result.%ToJSON()

This works, I can see the response is valid and what I want.

Hello everybody.

What I have is a criteria how to select "my" strings. What I need is to replace all of them with macro calls (using the same strings as arguments) in all classes of current namespace.

I was ready to write straightforward code, but at the last moment decided to ask the community: maybe I've overlooked a smarter option?

Any comments and advices would be great appreciated.

Hi, folks!

I'm sending emails with %Net.MailMessage.

How can I add a new line for the email body?

The code is:

dim msg as %Net.MailMessage = ##class(%Net.MailMessage).%New()
set msg.Charset="UTF-8"
do msg.TextData.Write("Dear  "_Username)
do msg.TextData.Write("Line1")
do msg.TextData.Write("Line2")
And I'm getting in email:

Dear UserLine1Line2

How can I get:

Dear User

Line1

Line2

I worked through the Community for proposals to provide end users
in an easy way with data formatted as EXCEL sheet.

There is a great article Tips & Tricks - SQL to Excel

there's an important message embedded: "EXCEL can interpret HTML tables and display them as usual"

Where's the light weight export to EXCEL ?
Good old CSP is well equipped to produce HTML tables accepted from EXCEL as input.
With modern Browsers you don't even need <head> and  <body> tags.
So the required code around your SQL result set is really slim.
And you are free to add any formatting you need either by HTML or in SQL.

I know there are numerous Java libraries available to scan a PDF meta data, but is there a way to scan a PDF using native cache object script? We are looking to take a PDF from an external vendor, scan for meta data, create the HL7 message, and embed the PDF within the HL7 message.

Thanks

Has anybody defined their own Cache ObjectScript (COS) commands and symbols? Is it even possible? For a list of currently used commands and symbols please use the following link.

I use %SQL.Statement. The original column names are not contained in the metadata.

Sample query:

SELECT
 column1->name as name,
 column2 age
FROM sample.table

How to get:

•  column1->name
•  column2

Good day, every process in my software is about to update 3 specific globals in row when the process is called to do some job. I need to guarantee that during updating of those globals with multiple processes there is only one process that is actually working with those globals. Moreover I need my globals unreadable if other process is in critical area.

Example:

(for example globals: ^data1, ^data2, ^data3 are critical area)

Should I use somehow function $LOCK() or there is another way how this can be done?

I am currently working on a issue with WRC on one of my Inbound SQL Adapters not returning all the records it should be. If I looked at the count of the records in Ensemble and compare it to that of a Microsoft SQL View, Ensemble seems to be off by a few records here and there. I am using a full dynamic select statement in my settings of the adapter.

Hi!

While i am trying to write a data i am getting a error as "<PROPERTY DOES NOT EXIST>zFile+15^User.zKQRest.1 *value,%Collection.ListOfObj" but there are values stored in it. How can i break it write it separately.

Hello everyone .

I am trying to update a setting of an operation directly via the code of a business operation.
Concretely, my customer want a counter for the number of calls to the operation and the possibility to redefine the point of this counter.

Good day,

I need to find out if it is possible somehow to receive actual linux TIMESTAMP for example with $NOW() or other functions.
I was trying to recalculate it with $NOW() function, but without success. I would like to simulate Redis TIME command in COS.

My tryings:

USER > set time = $NOW()

USER > w (($PIECE(time,",",1)*86399) + $PIECE(time,",",2))
5573319043.403186

But in Redis it is:

> time
​1) 1502471158

On web page: http://try.redis.io/
type "time" + enter. And it will results as short documentation says: https://redis.io/commands/time

And this behavior I would like to implement in COS.
