Hi Developers!

As you know the application errors live in ^ERRORS global. They appear there if you call:

d e.Log() 

in a Catch section of Try-Catch.

With @Robert Cemper's approach, you can now use SQL to examine it.

Inspired by Robert's module I introduced a simple IRIS Analytics module which shows these errors in a dashboard:

Hi Lucas,

I don't know if Cache or IRIS provides such feature. However, you could create a %Persistent class and link its data to ^ERRORS global in class's storage section.

Recently, @Robert Cemper did a great example mapping ^SPOOL global to a persistent class. May be this example could helps you.

Hi Robert,

Have you tired to export in UDL format (the UDL format is the document that we edit in Studio, VSCode, or in Atelier) via classmethod ExportUDL from the class %SYSTEM.OBJ

https://docs.intersystems.com/irisforhealth20201/csp/documatic/%25CSP.Documatic.cls?PAGE=CLASS&LIBRARY=%25SYS&CLASSNAME=%25SYSTEM.OBJ#METHOD_ExportUDL

To import you can use the classmethods Load, LoadDir  or any other method that load code from disk,. Or you can import from Studio to.

https://docs.intersystems.com/irisforhealth20201/csp/documatic/%25CSP.Documatic.cls?PAGE=CLASS&LIBRARY=%25SYS&CLASSNAME=%25SYSTEM.OBJ#METHOD_Load

For me worked export from:

IRIS for Windows (x86-64) 2020.1 (Build 215U) Mon Mar 30 2020 20:14:44 EDT

And import in:

Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2017.2.2 (Build 865U) Mon Jun 25 2018 10:50:02 EDT

In fact, It works!

Installation:

USER>zpm
zpm: USER>install terminal-multiline

[terminal-multiline]    Reload START
[terminal-multiline]    Reload SUCCESS
[terminal-multiline]    Module object refreshed.
[terminal-multiline]    Validate START
[terminal-multiline]    Validate SUCCESS
[terminal-multiline]    Compile START
[terminal-multiline]    Compile SUCCESS
[terminal-multiline]    Activate START
[terminal-multiline]    Configure START
[terminal-multiline]    Configure SUCCESS
[terminal-multiline]    Activate SUCCESS
zpm: USER>q

Usage with copy-n-paste from docs:

USER>d ^%zml
Entering multi line mode. Run with empty line. Stop with single "."
USER:zml:1> SET x=8
USER:zml:2>   FOR { WRITE "Running loop x=",x,!
USER:zml:3>         SET x=x-1
USER:zml:4>         QUIT:x=3
USER:zml:5>       }
USER:zml:6>   WRITE "Next command after FOR code block"
USER:zml:7> 
Running loop x=8
Running loop x=7
Running loop x=6
Running loop x=5
Running loop x=4

Next command after FOR code block
USER:zml:1>

It works like a charm!

Bravo, @Robert Cemper!

Extending the reply of @Robert Cemper

  • The following query compiles without errors, even though Studio highlights the error 
    &sql(select :fieldname into :fieldvar from :tablename)

    Everything is fine in Caché: the error occurs at the compilation-time.

    In order for an error to occur in IRIS Studio too you need to use the flag /compileembedded=1

  • It is strange that the documentation mentions field name, but there is no mention of table name:
    A host variable cannot be used to pass a field name or keyword into an SQL statement. proof

So, assuming @Vitaliy Serdtsev and @Robert Cemper answers we have:

Index ext [type = bitmap; Extent];

Is the must for every Persistent class, with standard ID, if we want to have fast answer on "How many records"

And the easiest and fastest "How many records" in this case is:

ClassMethod HowManyRecords(ByRef recordsCount as %Integer) As %Status

{
&sql(SELECT Count(1) INTO :recordsCount FROM schema_package.table)

IF SQLCODE<0 {WRITE "SQLCODE error ",SQLCODE," ",%msg QUIT}

}

@Robert Cemper

Whatever gets the process to work right!

I would consider WSL2 also.  Its probably just me, but conceptually I had a problem with running a virtual environment (VM) so I could run a virtual environment (Container).  WSL was not functioning well enough at the time so I went all in on Ubuntu as my native OS.

Good Luck ans

Thank you for your feedback @Robert Cemper 
I didn't run a benchmark, because in my case it's a deprecated class without intensive usage.

It's good to know the indirection performance is not bad. smiley

Interesting @Robert Cemper  !

I wrote a similar code the last year in order to have storage compatible Caché\healthshare and Iris.

We have a legacy persistent class mapped on ^CacheMsg global, my solution : 

<SQLMap name="CacheMsg">
<Data name="msg">
<Delimiter>"^"</Delimiter>
<Piece>1</Piece>
</Data>
<Global>@($s($zv'["IRIS":"^CacheMsg",1:"^IRIS.Msg"))@</Global>

It works very well, but perhaps a little bit slow due to indirection usage.

I'll keep this code until a complete migration to Iris and then It will be removed.

Top 3 most discussed questions are about ObjectScript.

Top viewed questions are about ODBC, JSON, CORS and Excel.

Top 6 voted questions are about @Otto Karlinger and Otto's fan club ) Do you think guys we need to cancel voting for questions?
