#Caché

Is there any way to specify in which order indices are built during:

• %BuildIndices
• %Save

So far I think they are built by name order.

Today, you need to find your way through a maze (again). There are 8 points of interest in the maze, and you have to visit them all, starting with point 0.
You may visit some points more than once, in random order. The challenge is to find the shortest path through the maze while visiting all points.

Dear community!

I have problem with index NULL value.  Unique index doesn't work for this case.  If I use insert and one of parameter is "NULL". Message of constraint doesn't appear and row is inserted into table successfully.  How Can I use index with NULL?

Class TestClassIndx Extends %Persistent
{
Property name As %String [ Private ];
Property age As %String [ Private ];
Property country As %String [ Private ];
Index IndextestUniq On (name, age, country) [ Unique ];
}

INSERT INTO TestClassIndx (name,age,country) VALUES ('1','2',NULL)

Hi everyone!

I'm restoring big database (1.8 Tb) from full backup to another host.

This host is weak (4Cpu 4GB RAM), so ^DBREST already works for 50 hours.

Is it possible to view restore process progres? I would like to know what  time it will take to complete?
 

Hi Guys,

Can you please guide me on how to develop the machine learning concepts like as Chatbots, voice recognition, etc...

If any lead would be appreciate. 

Thanks in Advance.

Thanks and Regards,

I ran the below query in three different modes.  Coordinated Universal Time is 5 hours ahead of Eastern Time so there is difference in value from column 1 and column 2 in ODBC, Display mode, but not in Logical Mode. By default the query executes in ODBC mode when we query the data from outside world(via ODBC connection). 

I don't know  why query 2 and query 3 outputs different from query 1.

Query 1. Ran in Logical mode, DATEPART() took in memory stored timestamp data(stored in UTC)

'Hour ' returned are same for both the columns

Query 2.

Remember the assembunny language we had to code on day 12 (https://community.intersystems.com/post/advent-code-2016-day12-leonardo…)?

There is a new instruction we have to implement which toggles an instruction x lines away (further or back).

• For one-argument instructions, inc becomes dec, and all other one-argument instructions become inc.

Dear community!

What do you think about webinar "Declarative programming on COS"? I want to do such one.

I am going to tell about main points of declarative programming and how you can implement it in your real projects.

Please feel free to write your opinion here.

Please if you wish to become a member of such webinar write me a message to atygaev.mi@gmail.com with subject "webinar".

I am in Atelier editing a Class.

I want to look at the window or pane that shows my Properties, 

I get to the tab that show Properties and their Value as shown below.

Now, how do I get the properties from my Class into the image below?

The goal of today's challenge is to copy data from one disk to another, problem is that the disks are not directly connected. Luckily they are in a huge grid, and you have to find a way to copy the data through adjacents disks, while honoring the disk usage (you cannot copy to a disk where data is already stored).

The input is a df-like disk usage listing.

Hello, this is going to be a stupid question, yea I know, there are no stupid questions.

Say, I have an Object Property, Name or Count or Title, or whatever.

How can I get a list, or find out all the different ways it can be expressed?

Example:

-Property Name As %Name;

-Property Name As %String="me"

-Property Name As %String [ Required];

But what other parameters, keywords, restrictions, lists, etc. that I can apply to this Property?

I have been search the I/S documentation and so far at least, I cannot find that sort of information, or in one place.

The challenge of day 21 is about scrambling passwords.

There are a few functions you need to implement that will do operations on a string :

- swap position X with position Yswap letter X with letter Y

Given the instructions in your puzzle input (look for a full explanation to http://adventofcode.com/2016/day/21), what's the scrambled version of the initial string  abcdefgh ?
 

Hi there,

The problem is, that I need use the property value of datacombo in other  datacombo with parameter.

The follow a example code: 

<dataCombo id="Grupo_Producto" name="Grupo_Producto" dataBinding="bdGrupo" size="40" 
label="(*) Grupo" dropdownWidth="400" dropdownHeight="100" loadingMessage="Cargando..."
columnHeaders="Codigo, Nombre"
queryClass="Innova.CL.Core.BD.Configuracion.Operacional.Grupo" queryName="obtieneGrupoProd"
 sqlLookup="SELECT Nombre FROM Innova_CL_Core_BD_Configuracion_Operacional.

Hello Community,

I have a simple question but somehow hard to find the solution:

this is a property in my class:

Property RelationAID As ZenCrm.Relationtypes;

this is my method to save:

ClassMethod PopulateMatrix(tvar1, tvar2) As %Status
{
set RelationMatrix=##class(ZenCrm.RelationMatrix).%New()
set RelationMatrix.RelationAID= tvar1
set RelationMatrix.RelationAType= tvar2
do RelationMatrix.%Save()
quit $$$OK
}

However the 'set' line does not work for the 'related properties.

I have tried: set RelationMatrix.Relationtypes.RelationAID but this failed.

Any suggestion? thanks!

Application Performance Monitoring

Tools in InterSystems technology

Back in August in preparation for Global Summit I published a brief explanation of Application Performance Management (APM). To follow up on that I have written and will be publishing over the coming weeks a series of articles on APM.

One major element of APM is the construction of a historic record of application activity, performance and resource usage. Crucially for APM the measurement starts with the application and what users are doing with the application.

We have an web application accessed using https, that uses CSP technology with frames.

The initial 'login' is via a single CSP page, which then redirects to another CSP page which creates the frames (4 in all) and loads a CSP page in each of those.  For the most part the frames load without error, but sometimes when logging in and sometimes while using the system ' 5916 Illegal CSP Request ' errors occur.

I say 'login' in inverted commas as a Cache login is not performed just an application login, I don't know if that's relevant so thought I'd mention it.

Does anyone know how to return the sys.process table with the corresponding configname item for each process? Also, is there a key for the Job Type field? 

I have restored one database from backup, but when I query from some of tables,   prompt error :

this error remain after restart Caché service

I can skip this error with %nolock in select query.

My question is: 

1. why there were locks after restart service?

2. Can I release/rollback these locks by sql so I can query without %nolock?

I have a query that I am attempting to run, but inner query is being rolled up into the overall query - per the optimizer (and jobexam observation).  While I know that if the inner query runs first, I will eliminate a number of records (making the result set smaller, and return quicker).

Just an example of what I am attempting to do:

select Account.Name, Account.State, Transaction.Amt, Transaction.Date, Transaction.Service
from Transaction 
left join Account 
    on Account.Id = Transaction.Account  
where Account.Id in (
    Select Account.Name
     from Account
     where Account.

We are almost there : after this challenge, only 5 days left till the end of this advent of code (I cannot wait to get my life back !) .

The challenge of day 20 is about a list of integer ranges. Some ranges overlap,  but there are also values that are outside any range.

You have to find out what is the lowest integer that is outside any range.

Today's challenge is a variation on the White Elephant gift exchange (https://en.wikipedia.org/wiki/White_elephant_gift_exchange), in this case, by a bunch of Elves where only one can have all gifts.

Each Elf brings a present. They all sit in a circle, numbered starting with position 1. Then, starting with the first Elf, they take turns stealing all the presents from the Elf to their left.

The challenge is about avoiding traps.

You can recognise if a tile is a trap by following scheme :

The first row is a given : a safe tile is shown as . and a trap is shown as ^

The challenge today is again a-maze-ing (as a wellknown president would say).

The maze has a bunch of doors ( | and - on the drawing), but they can be locked depending on a hash that you need to calculate every step.

I'm trying to write a method to Export SQL Privileges from an instance by namespace, user, or roles. I've found two classes that might work:

• ##class(Security.Users).Export
• ##class(Security.SQLPrivileges).Export

One (Security.Users) exports an XML file and the other (Security.SQLPrivileges) exports an SQL file.

Neither of these options allows me to specify specific users or roles to export so I'll have to use them in tandem with something else. Is there something else that I should be using or do I need to find a way to filter on the backend with regular expressions or the like?

Any suggestions on the most efficient way to convert yyyymmdd string to mm/dd/yyyy?

The challenge of day 16 is about generating random data using a modified version of a dragon curve (you can find more info on fractal curves like Dragon here : https://en.wikipedia.org/wiki/Dragon_curve).

First you need to generate data in a loop as follows :

Create an initial state with your puzzle input

Call the data you have at this point "a".
Make a copy of "a"; call this copy "b".
Reverse the order of the characters in "b".
In "b", replace all instances of 0 with 1 and all 1s with 0.
The resulting data is "a", then a single 0, then "b"

Repeat until your generated data is equal or longer than 272 digits.

I'm looking for information, suggestions, video (courses) on make a lot more use of the documatic system already built into Cache,

Probably talked of before within this forum, but after an hour or two of searching, can't find the articles that I mmay have seen before.

I want to do a lot more documenting of my installation, we use and actively comment classes and methods, but I want to take it further by actually documenting the "why" and high level "how" my system works. Documatic seems a good place to put that knowledge.

Can anyone suggest suitable Cache ObjectScript syntax for open/use/read statements on a simple ms-dos text file.
I've tried various examples seen on the web but they appear to be implementation specific.
I used MSM MUMPS many years ago but am now retired & would like to write a few simple routines for my own amusement & mental challenge.
I am using the free Version of Cache (V 2017.1) on my Windows 10 PC. The installation file was CachePCkit_x64.exe
My apologies for this query being very basic.

Hello Caché Guru,

I'm new to Cache system. I'm trying to do something like saving meta data in Relational DB:

I could use "management portal" -> System Explorer->SQL to view individual table's catalog details or print out the column definition. However I need to gather those information for several hundreds of tables in the DB. Is there a way to do it using command line in kind of batching mode?

Any hint and tip is very much appreciated!

Thanks in advance!
