By SQL priniciple:     
any straight name is meant to be a COLUMN of the actual table.  eg. Embeddings
but an external HostVariable is designated by an initial : (colon)  e.g.  : new_embedding_str or :params

This seems to be the deeper cause your problem

in addition I'd suggest to add  print(new_embedding_str)  to verify its format. (one of my problems.

Furthermore, take a closer look to this example:

Sounds promising:
in my COS example, I had to use pure String parameters like  "0.54456,0.6987646,0.I123" 
happened by accident, more for reading and debugging

I use a similar setup in my example in OEX ,
Especially with TO_VECTOR() I ran into problems if I didn't add the explicit
type and size of the vector.  e.g. TO_VECTOR("..........",,DOUBLE,384)
as model all-MiniLM-L6-v2  produces exactly that type and size:
Don't ask for why. I just used the proposed example

- Thank you @Andrew Wardly:
Your observation is pretty correct. It derives from a late Latin dialect spoken
around Locarno (today Switzerland) around 1600. Eventually starting with a very sharp S.
So the mental link to "Semper Fidelis" is pretty close and matches well.

eventually better to check for longer lists

USER>s x=$lfs("Purple,Black,Yellow,Pink")
USER>s y=$lfs("Red,Green,Orange,Yellow")
USER>f z="y","x" f i=1:1:$ll(@z) i $i(dif($li(@z,i)))
 
USER>zw dif
dif("Black")=1
dif("Green")=1
dif("Orange")=1
dif("Pink")=1
dif("Purple")=1
dif("Red")=1
dif("Yellow")=2

looping with $o() over dif() allows programmatic check

I just realized that $vector() is a left+right function similar to $li()

  • set $vector(target,...) = ....  to set
  • set vec = $vector(...)          to get

experimenting with class %Library.Vector I found an unattractive way:

;; compose JSON array  >> v
USER>zw v
v=[($double(.5)),($double(1.5)),($double(2.2000000000000001776))]  ; <DYNAMIC ARRAY>
USER>set vec=##class(%Vector).OdbcToLogical(v)
 
USER>zw vec
vec={"type":"double", "count":3, "length":3, "vector":[$double(.5),$double(1.5),$double(2.2000000000000001776)]}  ; <VECTOR>

Applying OdbcToLogical  was really shocking

Indeed:
I was unable to locate an official docu on new  SQL function TO_VECTOR()
Similarly, I found no documentation on how to set a VECTOR Datetype on pure object level
e.g. obj.vectorproperty = ?????? or obj.vectorproperty.set(?????)
I tried a bit with DisplayToLogical  but gave up in the end

Routine names starting with %Z or %z go to namespace %SYS automatically:
Though by mapping it to namespace %ALL any routine can be available in any namespace

Hi al!,
Just returning from some private troubleshooting I'm deeply moved and thankful for this feedback.
It's once more a motivation to continue my activities.
Sometimes I'm insisting on small pieces that may bypass general attention.
Though servicing customers - and I understand you all as my customers -
requires to take care also of the small and often annoying pieces. 

Special big THANKS to the brilliant team behind the DC+OEX+GM facility.
YOU ARE GREAT. 💐🌷🌺🌸💮🌼🌻

you are in Caché so this might help:
http://localhost:57772/csp/docbook/DocBook.UI.Page.cls?KEY=GIOD_rmsseqf…
USE file:position
the equivalent in %Stream,Object is MoveTo 
• method MoveTo(position As %Integer) as %Boolean

Move to this position in the stream. If this suceeds then return true, else return false. Note this implementation is not efficient because it searches from the start of the stream, it can be improved upon in specific subclasses. Note that moving to position 1 will be at the start of the stream, position 2 will be at the second character of the stream, etc.

And then you do your Read or Find..

Hi @Luis Angel Pérez Ramos

Just in case i misunderstood you.:

  • this is a storage concept for Objects and SQL
  • it is pure Globals and ObjectScript (M) in the core
  • take a look at the Globals used in the example and you see all that you are looking for,
  • and it is just ObjectScript that runs behind the scene

So: what are you looking for ?
And BTW. Its concept ia available for 4+ decades.
It just had no Object, no SQL, no fancy name then,

My Review - before being approved by OEX admins

  • This is a really excellent example on
  • How to publish in OEX
    • a clear to understand description of the target
    • a clean-to-install IPM package
    • a Docker setup easy to follow without any dirty tricks undercover
    • a fast and effective build and install that was tested in practice
    • so you can keep your working environment free of polluting code fragments
    • and a detailed understandable description of how to handle it
  • Big THANKS to @Kurro Lopez

Once upon a time ...

  • there was an operating system named VMS
  • running on computers named VAX and ALPHA
  • The syntax to access a file was  drive:[directory] 
  • it's the same structure used by RSX-11/M, RSX-11/D, RSX-11/S on PDP-11 processors

So on drive DUA1  you refer to director TEST3
