if you want to take a look behind the scene try this example
Character-Slice Index
Quick Summary:

  • [ looks for any character(s)
  • %CONTAINS looks for words (separated by blanks or punctuations)

Hi @Vivian Lee !
I think you had no chance to see the problem in docs
You mentioned a custom class that extends %Text.English
this might be the cause of your problem.
The class is not visible in normal class reference (don't ask me why) 
Default %Text.English has a Parameter  NOISEWORDS100 =
"the of and a to in is you that it he for was on are as with his they at be this from I have or by one had not but what all were when we there can an your which their said if do will each about how up out them then she many some so these would other into has more her two like him see time could no make than first been its who now my made over did down only way find use may long little very after called just where most know get through back";

So you might be affected by these NOISEWORDS.
I failed to find any useful public documentation on this parameter and also %Text.Text is not too useful

Agree with @Julius Kavay 
Just read the documentation  on %CONTAINS
It's a function specific to data type %TEXT and is language dependant (more details in docs)
-------------------
If you look for a functionality as SQL LIKE you better use LIKE
or [ the contains operator of COS

You still didn't understand the difference:

  • - DATDEDIFF() works on local times  eg.  "1970-01-01" is your locale time  (eg. UTC+5.5 hrs)
  • - $ZDT(...,-2)  uses by definition 1970-01-01 UTC

you should know from what time zone you  get your input from

Robert Cemper · Jul 5, 2023 go to post

#1 is correct
Your calculation #2 is seriously wrong.
reason
reading documentation you see
dformat -2 

$ZDATETIME returns an integer specifying the count of seconds from a platform-specific origin date/time. This is the value returned by the time() library function, as defined in the ISO C Programming Language Standard. For example, on POSIX-compliant systems this value is the count of seconds from January 1, 1970 00:00:00 UTC

And that's the mistake:
Your BirthDate is obviously considered as  LOCAL time
And therefore the difference you see reflects the time offset of your machine to UTC
-19800 sec => -5.5 hrs
system variable $ZTZ will show your offset to UTC in minutes  => -330
my guess: your machine is running at local time in India

I removed the article as it was totally out of date, misleading, and confusing.
Based on the very first versions of Sharding years back
+ an environment that doesn't exist anymore.

what you describe is explained in detail in the documentation:
%SQL.StatementResult

For a SELECT statement, if the cursor is positioned after the last row, the value of %ROWCOUNT indicates the number of rows contained in the result set.
At any other time, %ROWCOUNT contains the number of rows retrieved thus far.

Most important:: you run on x86-64 if Windows or Red Hat is not important to your CBK
If you still have access check the size of the original CACHE.DAT. 
Check also the standard collation of the original DB to avoid unexpected surprise
To my experience, there should be no difference for backups between C1017 and C2018 (the latest)

win docker desktop not just consumes fast-growing  vhdx
but also a lot of temp files, that get never deleted or shrinked
not even with deinstall / reinstall
typically in 
C:\Users\<usename>\AppData\Local\Temp\docker-scout\sha256 
C:\Users\<username>\.docker\scout\sbom\sha256
C:\Users\<username>\AppData\Local\Temp\  *.ico, *.vhdx

If I find no acceptable equivalent in PY
I wrap such functions, methods, variables, ... in 1 line COS (class)methods.
kind or embedded COS 😏

Robert Cemper · Jun 19, 2023 go to post

in the production view  you should find description and adapter description

BUT !!!!

This only works if the source is well documented. 

And that is often ignored by designers. even in ENSDEMO.
If it is missing it is kind of a quality issue

in Caché it is %installdir%/mgr/cconsole.log
and you can see it from MgmtPortal
and it would be helpful if you uncover the primary language you use

Robert Cemper · Jun 17, 2023 go to post

in your namespace you can map not just full Globals   
to a different Database but also parts of a Global.
This works over Global Subscript   Details
IF your structure is ^HISTORY(yyyymm, ....)    [yyyymm as first subscript ]
? eventually also your IDKEY ?
this is a possible way   to set   
^HISTORY(201606) >>  201606_HIPAA.dat 
^HISTORY(201607) >>  201607_HIPAA.dat

But if yyyymm is just somewhere in your data, you need to reorganize your global
I assume this is something  you have to do anyhow with your history 

ATTENTION: this is total static.
so for 120 DBs you need 120 mapping lines

just a hint:
Webterminal uses 2 connections:

  1. http/https
  2. wss/ws       websockets

this might cause problems. just my guess

In WEBCOMMAND I use just 1 connection (rather straight CSP)
with less  comfort

Confirmed!

Also if zipped typical IRIS.DAT is not accepted by GitHub because of size.
If cut to smaller pieces performance and flexibility are lost.

If not disabled all global SET and KILL and also transactions are documented in JOURNAL
there are also related search utilities available in %SYS
there is no equivalent feature for Global READ.
if you just look for the fact that there was a SET or KILL at object level
DSTIME could be an option see example: 
https://community.intersystems.com/post/synchronize-data-dstime
it is easier to handle than JOURNAL

I had some doubt in your initial question.

NowYOUR mistake is evident
you compose a JSON array args=[arg1value,agr3value,arg3value,..]
using %Push(..)

to %SQL.Statement this is just kind of a strange structured String
%SQL.Statement doesn't deal with JSON Arrays or Objects

with arg... you have to pass a local variable array
which is a core structure of Object Script (since ever)
arg=3           ;;<max subscript count>
arg(1)=arg1value  
arg(2)=arg2value
arg(3)=arg3value
as already described by @Julius Kavay

done on Caché 2018.*
s txt="-123.45E6789" if txt w "true"   >>> true
true/false stops checking Strings at the first nonzero numeric sign to set $T=1
almost since ever

Great improvement! 🥂

one of my (former) customers suggested this approach:

  • Train COS not on IRIS but on some Caché/ENS 2018 instances with Studio
  • or on some older IRIS version
  • As they run pure COS they have Studio for Training. An no need of new features
  • once all the logic works they may move the result to some final IRIS
    (if ever they migrated)
