#Caché

Is there documentation that states %Id() is supposed to be available in %OnBeforeSave()?

I am currently using it in this method without issues, but one of my colleagues is stating it is not supposed to be available for a new object at this point because the object has not been saved yet.  

I tried to implement the Oauth2 in google,

I got authentication, But I unable to read response class.

I got an error as:

I unable to change response Class.

Anyone help me to Change response Class in Client Configuration

                      or

Is there any option to define response URL manually?

Thanks

Today's challenge on http://adventofcode.com/2016/day/7 is about checking for valid IPv7 addresses with TLS support. (No, it has nothing to do with real ip addresses which are at most ipV6 or real TLS, but just a way to keep you busy coding & hacking!)

The imaginary ipV7 addresses support TLS if they contain an ABBA sequence outside square brackets and no ABBA sequence inside brackets.

I am a newbie to Cache and we are using dBeaver product to query against Cache tables. I have the following query which does a GROUP BY to aggregate the columns:

SELECT PtNumber,cpt4_OVR,CollDateODBC, COUNT(*)
FROM site.MGBILL_View 
  WHERE cpt4_OVR IN ('36415', '36416')
     --AND ChargeFlags = '0'
       AND CollDateODBC > DATEADD(DAY,-45,CURRENT_DATE)
  GROUP BY PtNumber,cpt4_OVR, CollDateODBC
  HAVING count(*) > 2

-This returns a count of 3 for each patient (aggregated)

But I need to display the actual 6 rows. I would typically do this by replacing the GROUP BY with an OVER(PARTITION BY

Hi I've created a word macro in order to convert doc to txt via the command line, this works fine via the command line by myself or another user but when I try as an the intersystems user which runs under  LocalSystem it doesn't work. 

So can I change the user, or set the $ZF to run as a different user?

Or do I have to try another way to convert doc to txt - it's looking like libreOffice?

I just wanted to stick with word because I could be guaranteed on the result being accurate.

Thanks

If you want to dynamically serve images as a property of JSON then there is no perfect encoding solution. One method used frequently is to Base64 encode the image. Whilst there are some negatives to doing this, such as data inflation, there are some positives to working with Base64 images inside the browser.

Let's say you have an image placeholder on a web page...

And you fetch a JSON message from the Caché server containing the image as one of its properties...

Without needing to decode the image data you can create an img

Hello, evrybody, I'm writing one project using CSP("OnPreHTTP"), and also REST angular. At the beginning I wrote purely on csp, then I decided to use angular for the flexibility of the client part. Now I can not design logging, I created a table App.Log with properties

I work in a small development company that uses Caché as a database. In some support cases I have doubts about whether the client's infrastructure environment is not affecting Caché's response time. Reading a bit about comparing installations in different environments, both in production as testing and homologation environments , I understood that the TPC-E is a benchmarking method accepted in the market.
I'm reading the specifications of the TPC-E and I wonder if anyone has implemented or seen something similar in Caché. Does it make sense to think about using this type of test to understand a

Hello; We are managing several Ensemble instances on several servers.  One server has 4 instances, and two other servers have one instance each (those are production servers).  We encrypt all instances using the Caché encryption in the management portal.

Currently we are using two different encryption keys: 1 key on the server with 4 instances, which is used for all 4 instances, and a second key on single-instance server. ( I'm installing the newest production server now.)

What I'd like to know is what are the best practices for managing encryption keys for separate servers. 

The options are to

I get two methods below: I would run both methods concurrently.

However, the "testRead" would always read the uncommitted results from "testInsert".

Anyway to avoid that? Thanks.

  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED, READ WRITE)
  &sql(insert into Test.Table(AttrA,AttrB,AttrC,AttrD) values(1,2,3,4))

}

  &sql(select count(*) into :ans from Test.Table)

Is it possible to make the cache terminal available over a mirrored vip address for a healthshare mirrored environment? So that connecting to a terminal for a mirrored environment will always connect to the Live Node?

I'm looking to write a Powershell script to run against the system and need to connect to the Live Node in a mirrored setup. Is this possible or am I going to have to log onto each node to establish which is Live.  Or does this even matter?

In this challenge, you need to find a password using instructions to move on a keypad.
Instructions can be U(p), D(own), L(eft) and R(ight).

You start at button 5 on a keypad like

1 2 3
4 5 6
7 8 9

each line of instructions lead to one digit of the password.
Full description can be found at http://adventofcode.com/2016/day/2

For example : ULL leads to '1' (a move outside the k

The Art of Mapping Globals to Classes (3 of 3)

If you are looking to breathe new life into an old MUMPS application follow these steps to map your globals to classes and expose all that beautiful data to Objects and SQL.

If the above does not sound familiar to you please start at the beginning with the following:

So just this morning we started to get this error from all of our SQL-client based tools that connect to our Caché SQL via ODBC: 

[%msg: <Error instantiating cached query class in Prepare(): <METHOD DOES NOT EXIST>Prepare+41^%SYS.SQLSRV *%New,%sqlcq>] (State:S1000, Native Code: 190)]

No queries work... any help? stumped over here.

doing a SQL query via Class %SQL.Statement

##class(%SQL.Statement

in Caché command line works... so that's why I think it's an ODBC issue..

I can't seem to find a SQLSRV class in the %SYS documatic

Greetings to all! Faced with such a problem, I ask for help, someone with great practical skills I think has already implemented this.The task was not to delete any objects from the database, but somehow mark this data deleted by client, because of this, I added Property Deleted As% Boolean [InitialExpression = 0];in the class.And in the redefined method %OnDelete:

ClassMethod %OnDelete(oid As %ObjectIdentity) As %Status [ Private, ServerOnly = 1 ]
{
        s person = ..%Open(oid)
        s person.Deleted = 1

Hello,

every time I open the management portal (http://localhost:57774/csp/sys/UtilHome.csp) the default namespace is %sys.

How to set the namespace to my preferred namespace instead %sys?
Is there a setting or could I change the link?

Thank you

Helmut

P.S.: In my attached example image I want always to have default namespace EXPERT when I open management portal

Hi, Community!

Suppose If you develop a client js application which works with Caché server via REST API (CSP Gateway).

What are the options for Authentication and working with Caché session then?

Hi,

I know you're doing a big effort to build a new IDE in Eclipse ecosystem but Visual Studio Code is a new an even better and faster tool for coding... did you have any plans to release any COS extension for it in the near future? There you can already find extensions for all current more common progrmaming languages and it would be great to have COS as one of them.

Thanks

I'm extracting text from HTML (more on how - here), and after I extract text it has two problems:

• Lot's of $c(10) control characters
• Multiple whitespaces

Here's an example of the text extracted from HTML page:

set text = " "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" Word1"_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(

This small function is of great need sometimes. My solution is straightforward:

I'm just curious whether other solutions exist. Is there some "standard" and/or quicker approach which I've just overlooked?

I have a classname and a property name. I want to know, when I get object value directly from a global, which property corresponds to which position in the $lb structure.
