InterSystems Caché is a multi-model DBMS and application server. See more details here.

What if you could serialize/deserialize objects in whatever format: JSON, XML, CSV,...; attending different criteria: export/import some properties and not others, transform values in this or that way before exporting/importing,...; and all of this without having to change the class definition? Wouldn't that be great??

Well, perhaps it's a goal too ambitious to reach 100% but, exploring this idea, I've developed a bunch of classes that I thought it was good to share. If you want to test, change, modify or improve the code, or just take a look at it, you can do it here. There you'll find a more detailed explanation (see Readme.md)

Be aware, this is a proof of concept for myself done in spare times, sure it's not robust enough or it can be done much better... but, I was just playing...ok, I could just wait to the new JSON Adaptor (coming soon!) that sure is going to resolve much more scenarios in a cleaner way, but... meanwhile... :-) ...

I am new to Intersystems cache COS scripts (cache is a client system). ThoughCOS scripts basically appear to be straight forward, I am having issues with the logon credentials. From what I have found in the documentation, the first 2 lines of the script contain the U/P. When running the script, the username is picked up correctly but the password is not. Granted, having U/P in a script is not ideal but will suffice as a matter of learning if I can figure out the formatting/syntax required. Any help on this would be appreciated.

ODBC Providers for SQL Server

Where can i get the latest odbc providers from SQL Server 2012/2016?

I see some posts on line to an ftp site out there but I am unsuccessful at getting access to it. I have a version loaded on my server but get errors when querying cache'.

"[Cache ODBC][State : 22005][Native Code 22005]"

Any help would be appreciated.

the one we have might be version 2014.01.05851 64 bit (would that make sense?)

I have a simple python script to pull table information from cache 2018.1.2 which is on a windows 10 machine. I get no results though the same query in the management portal works correctly:

import os
import sys
import intersys.pythonbind3 as ipyb
import numpy as np

# Connect to the Cache' database
url = "localhost[1972]:%SYS"
user = "xxxx"
password = "zzzzz"

accessKey = (url, user, password)

def main(accessKey):

Hello,

I am wondering if it is possible to access properties of a class from within a routine that has been called. See the below example:

Class TestClass Extends %RegisteredObject
{

Property Data As %ListOfDataTypes;

Method Query(parameter As %String)

How to get a Numbers View

In T-SQL, I can create a recursive CTE to create a subquery or a view that will hold a whole lot of numbers. Is there a way to do this in Cache SQL? I'd like the numbers from 0 to 10000 if possible.

Thanks!

Our company is in the process of converting our software for use in Intersystems IRIS and one of the major sections of the software makes use of a custom statically-linked C library using the $ZF("function-name") functionality. During this, I found out that the process for setting up the C library to be used within the database platform has changed significantly between Cache and IRIS.

%GetComponentByID Compile Error

Hello,

I have a class I'm working on that is extending a base class that contains the %GetComponentByID method and a section of the new code I'm writing uses %GetComponentByID but when I attempt to compile the class I'm getting an error that says the method doesn't exist.

Am I missing something to be able to include the GetComponent method in an extended class?

Can anyone clarify to me about the differences between these two classes?

People in this topic https://community.intersystems.com/post/using-class-queries-sqlstatement-versus-libraryresultset stated that %SQL.Statement (I am assuming they mean to talk about %SQL.StatementResult) is newer than %Library.ResultSet. But I don't really know what are the advantages of %SQL.Statement over %Library.ResultSet as the people in the topic somehow didn't mention them.

First,

Forgive me if this is a rather low-level question - I am a physician informaticist who is learning cache/mumps for the first time. I am sure this probably relates to some setting but I can't find a similar issue anywhere.

When I create a list, and then try and return that list - I get a bunch of symbols back along with my results, or sometimes I just get symbols.

I pasted a screenshot below. Thank is advance for the help!

I was searching for the most simple way to connect from visual studio code to my local instance via terminal without having to change any window.

I know this can also be achieved via telnet but seems a bit overhead if you're in your local machine.

For me the simplest sollution is to open a terminal window in VS Code, navigate to the /bin folder of your instance installation and run .\csession.exe INSTANCENAME

For simplicity you can just include your /bin folder in your path so you don't even need to navigate there

Currently, when we want to write data to a file that will be viewed in Excel, we parse the data in tab deliminated format to the file and name it with .xls at the end. That is sent to end users via email. They get a warning that the data is not formatted properly (it's not really an Excel file after all) but it does display somewhat correctly as the tabs are understood (this does not work if we deliminated with commas however).

With ^%SYSMONMGR, there are some brunches that I never found a way to quit out, like shows as the following example: do ^%SYSMONMGR --> Manage Health Monitor --> View Alert Records ...

Does anyone know the answer? thank you very much.

%SYS>do ^%SYSMONMGR
1) Start/Stop System Monitor
2) Set System Monitor Options
3) Configure System Monitor Classes
4) View System Monitor State
5) Manage Application Monitor
6) Manage Health Monitor
7) View System Data
8) Exit

Option? 6

I'm using Cache SQL and want the ability to choose a specific index.

I've boiled the problem down to one table and simplified the query down to

SELECT *
FROM Registration.PatResp
WHERE SchedApptNum=8450022

SchedApptNum is indexed, but instead of using that column, "Show Plan" indicates that it's looping through the entire Registration.PatResp table on Id (the primary key for the table).

I've done a tune-table with no change.
