#Data Import and Export

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 ?

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"
    }
  }
}

We are retiring a hosted application for an electronic health care records (EHR) system which stored the data on Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2017.2.2 (Build 867_4_20245) Thu Oct 8 2020 16:58:40 EDT. The hosting company is providing me with a single CBK file. I need to install a database system to restore the database and provide occasional SQL access for reports when necessary. I'll need to maintain access to the data for an approximately 10 year retention period. Not sure how to approach restoring this old of a database and eventually upgrading it to a newer re

Hello!

I'm new to Caché systems and I have a question...

I need to develop a custom task that daily exports the result of a query to a csv file in the database directory (I use the UNIX version).

Does anyone have any code or help to solve this case?

Thanks!!!

It can sometimes be useful to list or export all of the subclasses that are derived, directly or indirectly, from a given class. In Studio, the Class -> Derived Classes menu option will show such a list, but I'm not aware of a built-in API for programmatically exporting their source code.

Exported contents of a namespace on one server (classes, include files and lookup tables). Importing that code into a newly created namespace on another server. Both servers Ensemble 2018.1, same build. Export was via InterSystems Studio. Export is around 18Mb in total (XML file sizes).

When importing and compiling on the new server, getting errors as below - with #6301: SAX XML Parser error prominent - on a number of the imported files, all containing data transformations or business processes.

hi,I meet a problem,i want to move huge data from ensemble to oracle.it`s about 3years business data.i have tried some case！

1. EnsLib.SQL.OutboundAdapter

i parse the data one by one,and translate it into inser or update sql statement then write to Oracle，it·s most slowly，and take more disk space。

2.save the data to a new table，and then use dbeaver transport data to oracle。

3.user linktable. save object as insert，but，i can·t user %openid method.

Is there a way to do something like $SYSTEM.OBJ.ExportAllClassesIndividual() for the routines?

I'd like to export all routines in single files

In terms of general through-put design and long term support, I'm considering what would be a "best approach" for needing to create multiple batch files in a few different layouts from the same data-sets.

I am creating "models" that contain rows in several class tables called Model, Path, Node.

So, model 19 includes 1 row in the Model table, 11 rows in the Path table, and 10 rows in the Node table.

I'd like to write some utilities to "move" model 19 from one instance to another.

Hi everyone,

How do you alter primary key on a table that has data?

Any example much appreciated.

Cheers,
