NewBie's Corner Session 14 Inline Do & Nested Do with Implied Quit and For Loop

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

InterSystems Caché provides a GUI (Graphical User Interface) based Integrated Development Environment (IDE) called Caché Studio. Developers can use Studio to create and maintain applications.

The following concepts of Inline Do, Nested Do, Implied Quit and For Loop is difficult to explain in a manner that everyone understands. However, these concepts work well with each other.

1. What is this talk? • Provocative • Conflicting • Irritating • For those who want to be professional • Driver

2. What is this talk not? • Silver bullet • Only for devs Java • Only for devs • To be forgotten

3. Debt technical or "how to prevent the conductor knock on your door" - Alexandre Freire https://www.infoq.com/br/presentations/divida-tecnica- need-credit

4. Developers do not know fundamentals!

Hi all,

          Is there any possibilities to set the null password for user account in cache 2016?

Thanks,

In our last lesson, we added a form to Edit our existing Widgets, and save them back to the server.  However, our Form was not well strcutured and our Save button had no intelligence, and was not fully visible.  So today, we will apply some Material components and Angular style to make the form more useful

Let's open EditWidget.csp, and make some changes.  First, we want to change the component from an md-card to an md-dialog.

Let us check whether this is available to others

As you know, Caché can be used as a relational DBMS working with JDBC/ODBC drivers and supporting the execution of arbitrary SQL queries and SQL procedure calls. 

We also know that Caché stores all the data in multi-dimensional sparse arrays called globals. It allows the developer not to use the standard CachéSQL engine in case a particular SQL procedure is underperforming, but instead rewrite its execution code in the Caché ObjectScript (COS) language intended for server-side business logic. This approach may help implement the optimal SQL procedure execution algorithm by using better-optimized NoSQL data structures (globals).

However, the standard class library in Caché has one limitation: for SQL procedures where data selection is controlled by custom COS code, you need to define the set of returned fields at the compilation stage - i.e. it is impossible to dynamically define metadata for an SQL procedure working with NoSQL structures. This article is about how to get around that limitation.

Hi All, I am taking a namespace and routines from one table for particular user.if the user have name space and routine means it execute well but after executed the routine it is automatically quit and close the session.I need to keep the same namespace after executing the routine. Please help to proceed further anyone.

Hi,

I would like to list out unchecked mapped items ( classes in management portal )  classes of a particular namespace. Is there any code or terminal command which i can use ?

I am able to list out classes of namespace . But I need to list out unchecked mapped items classes

do ##class(%SYSTEM.OBJ).GetClassList(.result)

AI can be categorized in any number of ways, but here are two examples.

The first classifies AI systems as either weak AI or strong AI. Weak AI, also known as narrow AI, is an AI system that is designed and trained for a particular task. Virtual personal assistants, such as Apple's Siri, are a form of weak AI.

Strong AI, also known as artificial general intelligence, is an AI system with generalized human cognitive abilities so that when presented with an unfamiliar task, it has enough intelligence to find a solution.

Hi All, I configured the crystal report SAP 2011 with IIS 10 in windows server 2012 r2 standard,when I tried to open it shows failed to open the connection error .database is Cache.how to recover that problem.

Hello everyone,

I have the following problem in generating a PDF report in ZEN, which has many items, a general total of approximately 30,000 items, but gives an error, I can generate a report with a maximum of 8,000 items, which may be wrong.

Hello,

I'm just re-going through the Caché foundations course exercises using a copy of Try-Caché on my home pc.

I'm trying to create a web application to receive REST calls however, when I use the Restlet client I get no response.

My web application config is:

Currently we have a setup where we have an external IIS webserver that our CSP Gateway sits on that routes requests to our ensemble server. When working with soap everything was routed to the CSPms module since the site's handler mappings have *.cls going to this module. However, now that we are working with rest services that don't have a file extension we will have to have all traffic on the IIS box be routed through the CSPms module. 

I was curious if anyone has encountered this type of issue, and if so, what steps did they take to resolve it?

Hi, I don't know if there is a bug in the function $zdate.

if i do:
w $zd("43433",4)  the result is    01/12/59

but if i do:
w $zd("64448",4) the result is   14/06/2017

Configuring Java with InterSystems Technology

Regardless of what InterSystems technology you use to design your applications, it is likely that some of our product functionality will require that Java be installed on the operating system, and subsequently be configured properly with your InterSystems based application. There are many ways that this can be accomplished depending on your operating system, as well as the specific InterSystems technology you are integrating with.

Advent of Code is a series of 25 small programming challenges, created by Eric Wastl, see https://adventofcode.com/.

There are small and bigger puzzles, which you can solve typically in half an hour to a few hours. (Looking at the leaderboard, the top aces can do them in less than 10 minutes.) 

It's an ideal way for beginners to start learning a computer language, and for advanced people to sharpen their programming skills.

To help you get trained for this year's challenges which start at December 1st, I will try to solve and comment the puzzles from 2016.
