Within an ObjectScript structure, direct access via globals - although no longer very common - is very fast, and especially useful when you have a very large number of subscripts for the same node, and you only want to know the value of the last subscript, in which case you can simply read using the reverse $Order (equivalent to ORDER BY ... DESC or MAX(), however, without needing to construct an SQL read method), especially if you have a mapped class.

Yes, this difference in indexing, starting with 0 in one case and 1 in another, is really confusing. I never remember which situation applies to each case, so I always have to do it by trial and error.

Wow, this is a very interesting guide! The last time I needed to switch computers, I redid all the connections manually.

Hi! The complete code example makes it much easier to understand, thank you very much!

It's great to see you mention MUMPS, which has always been praised for integrating applications and databases in a very natural way, and the evolution to IRIS has made this integration even easier by incorporating other languages ​​and native interoperability.

I really liked the way it was structured; it was very easy and didactic! Extremely simple for those who need to take their first steps in IRIS technology!

It's a unique opportunity to discover the latest innovations in the world of technology.

This article came at a good time, we were discussing services related to RabbitMQ just a few days ago. Thank you very much!

Nice article! I did a simple count test on a table with approximately 75,000,000 rows, and the time dropped from 22 seconds to 6 seconds using %PARALELL. Thanks for reminding that it is available. We don't always remember to use it, but we should... :)

Great article! I've been using JWT for a little over a year, but I had some difficulties implementing it fully at the time. An article like yours is very helpful in clarifying some doubts!

Great! I've only been using JWT on IRIS for a short time, but it's very practical!

Here in the South of Brazil it's still winter, and during this period I didn't take any vacations... so, just a little reading and watching in my free time (which is little... hahaha)

It was winter... but it looks like you did more than if it were summer... hehehe

Very good and interesting, I wasn't familiar with %MATCHES and %PATTERN in SQL. Thanks for the clarification!
