#Data Import and Export

Hello everybody,

I would like to export project contents using Visual Studio Code, as well as I do with InterSystems Studio.

However, while attempting the export through the InterSystems extension I get the following error:

- There are no folders in the current workspace that code can be exported to.

These are the step to reproduce my error:

Hi folks!

It is very easy to import CSV data into IRIS. But what if we want to preserve the original IDs in CSV?

Recently I came across with the situation when I needed to import two csv's into IRIS which were linked by one column referencing to another csv's col: a typical Foreign Key and Primary Key situation, where csv1 contains this column as Primary Key, and csv2 as Foreign key with id's related to csv1.

The image is generated by ChatGPT so don't blame it - it tried its best to generate countries as primary keys with countries.csv-cities.csv relationship :)

Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.

Dynamic Objects

Dynamic Objects are very similar to the standard ObjectScript object model you get when you create a new instance of a class object, but with some key differences:

Hello

This article follows up on the question I had asked the community UDP Adapter not working

In this article, I will present to you

Hello everyone,

I’m facing issues with replicating data from my Caché 2016 database to a PostgreSQL database. I need to handle around 300 data updates per minute, and whenever certain tables are modified, those changes must be reflected in other databases.

So far, I’ve tried various approaches, including:

Hi!

Suppose I have full access to InterSystems IRIS database instance A and want to export a consistent part of the data and import it into another InterSystems IRIS instance B. Classes are equal.

What are the most general and convenient options for me?

TIA!

Hi! I am trying to export Cache data to my SQL database and am trying to export the schema as well.

The Data Export wizard on the Management Portal only allows me to export the data but not the schema. Is there anyway to get the schema exported as well?

As the title suggests, I would like to programmatically export each individual data lookup table as XML, either as a stream object or to a file. How would I go about doing this?

when doing ETL process from cache database to mysql database(ods) and to another mysql database(dwd).

There are lots of DR columns in one table.

In the first step we need two databases to be totally consistent(ods=cache database)

However, the DR column in another database lost its meaning and become to normal number.

In the last step we do the data governance in ODS to DWD. My question is how to write sql without many `join` in this step.

Is there a way to use the %JSON.Adaptor to project readable JSON when a property is defined as a %Integer but with a DISPLAYLIST ?

Hi,

I have an odd problem that occurs when I'm trying to import lookup tables in the XML format into Studio.

I store my files in in C:\CodeRepository.

I can manually import these lookup tables using "Import local..." option in the InterSystems Studio.

However, when I'm trying to import them using command in terminal: do $system.OBJ.LoadDir("C:\CodeRepository\","ck")

I'm getting the following error:

I am exporting data from Cache using the SQL export wizard. This is on a docker image of Cache hosted on a Linux server.

I select my database, schema, and table, make sure that all columns are being exported, check other settings, and then finish the export.

All server settings look correct and permissions are rwe on the directory. I have tried various directories, including a system level directory. I tried creating the file before I do the export in case there was an issue with creating the files, and I also made sure the created files had rwe permisisons.

Is it planned that LOAD DATA takes into account several DATE/DATETIME formats with, for example, a parameter indicating the format used in the source data?

example :

LOAD DATA .../...
USING
{
  "from": {
    "file": {
       "dateformat": "DD/MM/YYYY"
    }
  }
}
