Tutorial - Working with %Query #2

My previous article introduced you to SQL based Basic Class Query
where a clever wizard created all the required code for you and your essential
contribution was an SQL statement.

Now we enter the real Custom Class Query that provides more freedom but
requires a deeper understanding of the mechanic behind the scene.
The full code example is again on GitHub

Hi guys,

Suppose I have a JSON string as below:

{"MessageID":"11111","save_date1":"2022-02-02 01:01:34","Sender_ID1":"esb","sent_date2":"1985-12-11 11:42:00"}

The two date variables are all formatted as ODBC date time, when I tried to import it to a %JSON.Adapter object, the date format was rejected as below

Error #9406:Unexpected format for value of field, save_date1, using class base mapping

Thus I'm trying to format all possible ODBC date time in the incoming JSON with Regular expression:

Hi everyone,
I met this Jenkins build problem when commit to P4.

ERROR #5001: GUID reference(s) missing from stream websys/TranslationType/questionnaire.QCNXXCVD.Edit/68D7225A-DE63-11EB-AF4C-005056B66BA0.xml; 35551C28-0C38-11EB-A1C8-005056B66BA0

So how can I solve this problem. Would anybody help me?
Thanks.

Dear community

I'm using HealthShare on Cache 2017.2. I'm trying to find out how I can get a list of all the custom classes, routines and globals in %SYS namespace (if it's even possible).

We're about to perform an upgrade, and in the docs it mentions needing to check for anything custom in %SYS to avoid important stuff being overwritten. Some of our solutions have been developed by an external consultancy and we want to make sure that none of their code or data will be affected by the upgrade.

Hi,

I like to validate some use cases and have the following question. I am relatively new to IRIS. Perhaps someone can help:

1. I have a global m[x,y,z,f] distributed across multiple sharded instances
2. I know that i can set assign computed SQL expressions to class variables using Objectscript
3. Is there a possibility in Globals API to do the same ? Set f = x + y as a computed expression in the global m[x,y,z,f] ?

a. We would want to use the global API to change f programmatically using code

Hi,

I have a production with a BS calling a BP calling another BP and so on and finally a BO. All calls are made using SendRequestSync.

The initial request is passed by value. The response is passed by ref and I allocate memory for it in the BO, hoping that it will go back to the initial caller in the BS, but it does not.

It looks like the following:

Preview Mode was added to InterSystems IRIS Business Intelligence to give designers a quick view of what their resulting Pivot Table will look like without needing to wait for the results to fully execute. This can be beneficial when designing pivot tables because if you are dragging and dropping elements to see how they look/work in your pivot table and seeing if they have the desired data. Since you are exploring and designing, you don't necessarily care about the results at the moment, but you would still like to see how your table looks with the changes you have made.

I have a class which, in the previous instance, was able to extract metadata field names and data from a text file, and load this information into a domain. I am trying to run this in the field test instance, but it is not loading the metadata - only the field names. I am not getting an error, but the data is not loaded.

The few changes I made to the original class:

Previously, this class also ran iTables. I commented all that code out.

To create the domain, I replaced the line:

Hi developers!

Observing the avalanche of AI-driven and vibe-coding developer tools that have been appearing lately almost every month with more and more exciting dev features, I was puzzled whether it is possible to leverage it with InterSystems IRIS. At least to build a frontend. And the answer - yes! At least with the approach I followed.

Here is my recipe to prompt the UI vs InterSystems IRIS Backend:

  1. Have the REST API on the IRIS side, which reflects some Open API (swagger) spec.
  2. Generate the UI with any vibe-coding tool (e.g., Lovable) and point the UI to the REST API endpoint.
  3. Profit!

Here is the result of my own exercise - a 100% prompted UI vs IRIS REST API that allows to list, create, update delete entries of a persistent class (Open Exchange, frontend source, video):

What is the recipe in detail?

I have an application that is called by terminal in local cache environment. The application basically has two processes that runs and does the below call to retrieve files and sub-directories in separate folders. When the main process starts, it jobs off and calls the second process that gathers all files in a directory by using a window dir and file command that pipes the results to a file. The main process continues on and does the same thing but from a different folder. When checking out what was retrieved by the secondprocess, there were directories and files missing. When I run this as just one process it works properly. I am running this on a 2017 license cache instance. I have also tried this on IRIS instance and got the same results. Could you please advise me what is causing the window directory to not work properly when running the processes at the same time?

Hi Experts

I am trying to pull the code tables Information and this code table has linked code table not exactly obviously joined by SQL tables or columns. This is confusing me. Please can you clarify how to link these two tables.

I will be generic to ensure, any privacy is protected

CT_Hospital has CT_Staff linked in.

When CT_Hospital has data, for that relevant hospital code, CT_Staff can be clicked and data entered.

When I see in the Components - > Items I do not see any SQL table or SQL column common between CT_Hospital and CT_Staff.
