OK: %ALL means really all.- no surprise
in your list, I miss role %SQL which gives access to all INFORMATION_SCHEMA.*
as @Vic Sun just pointed out

Hi Nigel,

I experienced this missing UNINSTALL feature several times filling up my working environment.
So I adopted this  strategy:
- if there is no Docker container in the project I instal one of the prepared templates
- As packages are (or should) independent of the platform I enter the container and install it there
simply running docker-compose exec -u root iris bash and  execute the installation
and when finished just removing containers and images and I'm back to roots.
It only fails if I run against the 5 connections limit of the community license. But that's untypical.

maybe a misunderstanding.

if you execute a HTTP request YOU are the visitor at that side and get a response.
do you look for your own IP address? 

Robert Cemper · Jun 17, 2021 go to post

the base class for all Webpages (also REST) from IRIS is %CSP.Page.cls
When a csp request is received, the CSP Server creates an instance of the %CSP.Request class. This is accessible via the %request variable. It holds all information about the call.
Also all CGI variables.  HTTP_REFERER might be what you look for
and that's all core HTTP

The SQL statement should look slightly different

Insert Into TableX (Name, Address, Phone)
SELECT 'Name1', 'Address1', 'Phone1'
UNION
SELECT 'Name2', 'Address2', 'Phone2'
UNION
SELECT 'Name3', 'Address3', 'Phone3'

Thanks for raising the issue.
I experience the same behavior with a fresh Docker Image

Robert Cemper · Jun 26, 2021 go to post

20/30 tables and 300 columns is quite a heavy query / view.
VIEW is only a stored SELECT. The same considerations apply. 
#1)
you should have an index for each column that appears in a JOIN ON..   on WHERE...
and that's hopefully just 1 index by table
#2) for each table the required columns should go as Data into the index
You are perfect if the query analyzer only shows access to indices.

My proposal only covered views of a single table with indices

Materializing a multi-table view as you describe it would require a hidden table with all JOINs
and no filtering WHERE clause. And you would require extra code to keep it up to date.
This is a job that the query generator does in an excellent way and with all tricks available.
I wouldn't say it's impossible. And the final query is definitely faster. 
But it may take weeks or months to get it running. Not to talk about maintenance.
Analytics/DeepSee acts in a similar way. And I can prove: it wasn't done in an afternoon session.

my PullRequest is pending.
IMAGE=intersystemsdc/iris-community:2019.4.0.383.0-zpm
is broken as it starts with SHELL ["/irissession.sh"]
instead of SHELL ["/bin/bash", "-c"]

Newer imags don't have that problem

IRIS includes a bunch of "legacy" routines".
Typically %R*, %G* that you can load by "legacy" commands in a "legacy" session or terminal
(not webterminal or simliar commandline simulatiors)
They are hidden in some way, It is not specific to VSC but the same with Studio.
Though ZL %RI ZS %zRI should create a routine that you can work on. Z*,z*%Z*,%z* is writable Use code

don't think so complicated. leave your serial object as it is
but use instead a CALCULATED, SQLCOMPUTED Property as $LB()  and you can then index it

Robert Cemper · Jul 4, 2021 go to post

Ok. the picture becomes clearer: 
%SerialObject is stored as $LB($LB(....),...)
you can get your result by 2 steps. 

do attribute.%SerializeObject(.serialraw)
set list=$list(serialraw)
Robert Cemper · Jul 4, 2021 go to post

Zdravo Matjaž!
you are right in principle. Though there are hundreds of similar cases since DECADES!
ok, the cleaner solution brings us back to my previous proposal.
add a calculated property to your serial class ##class(Packing.Needs.Attributes) like this

Property List As %List [ Calculated, SqlComputed,
   SqlComputeCode = { set {*}= $LB({attr1},{attr2},{attr3},{attr4} ) }, SqlComputed ];

attr1,attr2,attr3,attr4 have to be the SQLnames of these properties !!!

WARNING#1: you have to maintain this list manually at every change of the attributes!

WARNING#2:: this calculation happens at every access to the object. 
The additional parameter     SqlComputeOnChange = (attr1,attr2,attr3,attr4) 
may reduce this. though I've never tried in practice

Out of curiosity, I checked the size of the underlying OBJ code:
> object size = 380  (+47% !)  + timestamp = 18

So the expected gain is not what you would assume at first sight.
For the  price of an almost unreadable code

leaving aside that there are  evident typing errors that break the code
your reply underlines that the criteria: "Shortest answer wins!"
misses the precise definition of what is measured.
There is not much chance to be shorter than "x x q o"  (= 7 char)

put it into %ZLANGC00 as ZY

and just have 

ClassMethod ToNato(t)   {
  ZY
}
