In this article, I aim to demonstrate a couple of methods for easily adding validation to REST APIs on InterSystems IRIS Data Platform. I believe a specification-first approach is an excellent idea for API development. IRIS already has features for generating an implementation stub from a specification and publishing that specification for external developers (use it with iris-web-swagger-ui for the best results). The remaining important thing not yet implemented in the platform is the request validator. Let's fix it!

Hi everyone,

This is the first time I'm dealing with a request of modifying a variable value in a UDF OnSQLTrigger on InterSystems TrakCare.

I can't find any documentation to address this issue, but basically, my goal is to modify the value of one of the fields in a table when it is first inserted.

This is basically what the code should do, namely, to change the content of the %d variable at a specific key.

Hey everyone,

I'm just seeking some guidance and confirmation on what I'm doing for my production health monitoring.

We utilize Grafana to have reporting/monitoring dashboards and I have made a REST API to query the health of our productions. I believe I have everything figured out except for one thing that I'm uncertain about and that is the Production Item Color indicators:

Why do these clauses affect SQL performance?

select ID from some_table where row_status in ('I','U') order by ID limit 5 - makes the query infinite
select top 10 ID from some_table where row_status in ('I','U') order by ID - the same
select ID from some_table where row_status in ('I','U') order by ID - is fast

Actually there are no rows in the table having row_status 'I' or 'U'.

I asked Gemini and it recommended me rewrite the query as
