#Caché

I have a simple app which tries to establish a connection with a Cache database instance via Global API for Java:

import com.intersys.globals.Connection;
import com.intersys.globals.ConnectionContext;

public class Assignment {

    public static void main(String[] args) {
        Connection connection = ConnectionContext.getConnection();
        connection.connect("SAMPLES", "_SYSTEM", "SYS");
    }

}

The expection I am getting:

I am trying to fetch the data from cache database. But i got the error like "CSP application closed the connection before sending a responce".

Below is the query.

SELECT
CallbackComment
FROM SQ.CBPhoneResult_View Where PhoneDateODBC = '2018-04-09'

I have investigated and found that "CallbackComment" contains the special character single quotes " ' " for one result and due to this i got this error.

In this field data is enter by customer. so we cannot restrict them like Do Not use single quotes.

Would like to know if there is an alternative or better way to paginate through a dataset using dynamic SQL than what I am using below. The problem is that as the potential pool of data gets larger, this code slows down to the point of not being useable. In analyzing each line of code below, it appears the slow down is related to the initial rset.%Next() iteration. Is there anything available which does not require a subquery/%VID such as a simple LIMIT/OFFSET?

My code is similar to :

s sql=##class(%SQL.Statement).%New()

Hi, Community!

Please share your experience on code deployment on production site. Do you compile ObjectScript on Production? Is it OK?

Or you only compile on Test site and copy cache.dat to a Production?

My new question regards connecting to the external database to insert the data. I have the following code:

I need to start doing unit testing for some of my code.

Why does it delete the unit testing class from Cache when I run the test?

Is there a way to turn this off?

InterSystems states that Caché supports at least three data models – relational, object and hierarchical (globals). On can work with data presented in relational model in a program written on C# the same way one works with any other relational DB. To work with data presented by object model in C# one needs to use .NET Managed Provider or some kind or ORM. And starting with version 2012.2 one can work directly with globals (or use direct access to hierarchical data) via Caché eXTreme for .NET.

I would like to examine the contents of my OBX-5 field and not route the message if it contains alphabetic characters. I've tried various combinations of the Match and Contains functions, with no luck. Should I be using the COS ? operator or plaini regular expressions?

e.g.

OBX-5 Contains "\D"

OBX-5 Contains "?.A"

OBX-5 Contains "[A-Z]"

Hi all,

I'm wonder what could be the best way convert the sentence "Switch" C# into Cache code.

int caseSwitch = 1;

switch (caseSwitch)
{
    case 1:
    Console.WriteLine("Case 1");
    break;

    case 2:
    Console.WriteLine("Case 2");
    break;

    default:
    Console.WriteLine("Default case");
    break;

}

My first attempt was:

We are going to start using Git within Cache.

One question came up - if the branch that you checked out does not have the class or mac file, what is the correct thing to do?

Should we delete from Cache or should we just keep it?

I'm leaning more towards deleting it because Cache should reflect what is in your work folder in git. But other team members are saying to keep it.

Hello, Community!

Here's an interesting task I found on the Internet.

Problem description

Write a method that would draw a box of a specified size.

The goal is to write the shortest method.

Here's a method signature (it can't be modified):

ClassMethod main(s As %Integer = 10)

And call sample:

>do ##class(ITPlanet.Task4).main(5)
#####
## ##
# # #
## ##
#####

>do ##class(ITPlanet.Task4).main(10)
##########
##      ##
# #    # #
#  #  #  #
#   ##   #
#   ##   #
#  #  #  #
# #    # #
##      ##
##########
 
>do ##class(ITPlanet.Task4).main(20)

A function iterates global ^data(a,b,c) with $order using 3 nested for-loops. At certain point, for example with a=10, b=20, c=30, the function exits and later has to resume the iteration from the same point. What could be easiest way for it? My solution looks too ugly.

I keep seeing <INVALID OREF>zMyproperty

most of my jSON data is single words, but when it comes to sending chunks of a memo/email via JSON, that totally different

which is the correct conversion process to prepare data ready to insert into the data part of a JSON string so that all problem characters are converted

JSON of course crashes if you use the wrong format of quotes (single or double) and you ned up having to use &QUOT and \' to get around that but is there a simple call to something that will just take care of preparing the data from the JSON string both on the inward and outward part of JSON
