Perhaps pass the object ID into something like:

Query GetInfo(refId As %String) As %SQLQuery(CONTAINID = 1, ROWSPEC = "IdList:%String,IdProcess:%String,Duration:%String")
{
    SELECT list.IdList, list.IdProcess, list.Duration
    FROM Kurro.MyClass list
    JOIN Kurro.MyClass ref on ref.ID = :refId
    AND ref.KeyProcess = list.KeyProcess
    AND ref.CodeSpecialist = list.CodeSpecialist
    AND ref.CodeProvider = list.CodeProvider
    AND ref.CodeCenter = list.CodeCenter
    AND ref.Date = list.Date
}

This is really interesting - I've been starting on a similar project with the same starting point.

This is the right answer. It would be nice if there was a more built-in way to include row IDs in %JSONExport without having to do this though.

The closest thing to what you're looking for is %VID (link to documentation)

You can use this even without an actual view as follows (for example):

select %VID "RowNumber",* from (select top all AirportLocation, FAADistrictOffice from Aviation.Event order by FAADistrictOffice, AirportLocation)

With what we've done the syntax ends up looking like:

Class DC.Demo.Hierarchy Extends %Persistent [ MemberSuper = AppS.Index.Methods ]
{

Property message As %String;

Property login As %String;

Property parentId As DC.Demo.Hierarchy [ SqlFieldName = parent_id ];

Index parentId On parentId [ Type = bitmap ];

ClassMethod RunDemo()
{
    Do ..%KillExtent()
    &sql(insert into DC_Demo.Hierarchy (message, login, parent_id)
        values ('Bacon ipsum dolor amet pork shoulder ribs', 'User 1', null))
    &sql(insert into DC_Demo.Hierarchy (message, login, parent_id)
        values ('BGouda croque monsieur emmental.', 'User 2', 1))
    &sql(insert into DC_Demo.Hierarchy (message, login, parent_id)
        values ('Manchego fromage frais airedale', 'User 3', 2))
        
    Do ##class(%SQL.Statement).%ExecDirect(,
        "select id, message, parent_id from DC_Demo.Hierarchy "_
        "where id %FIND DC_Demo.Hierarchy_parentIdFind(2,'all descendants')").%Display()
        
    Do ##class(%SQL.Statement).%ExecDirect(,
        "select id, message, parent_id from DC_Demo.Hierarchy "_
        "where id %FIND DC_Demo.Hierarchy_parentIdFind(3,'all related')").%Display()
}

}

Because there's a self-referencing property with a bitmap index, the hierarchy support is automatic via the MemberSuper class. Output is:

d ##class(DC.Demo.Hierarchy).RunDemo()
ID    message    parent_id
2    BGouda croque monsieur emmental.    1
3    Manchego fromage frais airedale    2

2 Rows(s) Affected

ID    message    parent_id
1    Bacon ipsum dolor amet pork shoulder ribs    
2    BGouda croque monsieur emmental.    1
3    Manchego fromage frais airedale    2

There's nothing built-in for this, but you can simulate it via custom class queries or %SQL.AbstractFind. I have an implementation of %SQL.AbstractFind/%Library.FunctionalIndex that does some things with hierarchies but falls short of the capabilities you linked in the Oracle doc. Specifically, it can find all ancestors/descendants/both (the whole tree) in a hierarchy efficiently, but it doesn't follow the same rules around ordering and won't let you do paths and such. (I'd want to clean it up a good deal before sharing, but that's probably worthwhile at some point.)

@Daniel Bertozzi , following up - I downloaded ImageMagick and the following works just fine for me (though I'm a little surprised at how slow it is):

Class DC.Demo.ImageMagick
{

ClassMethod Convert(inFile As %String = "C:\Temp\ImageMagick\inFile.jpg", outFile As %String = "C:\Temp\ImageMagick\outFile.jpg")
{
    Do $zf(-100,"","magick",inFile,"-resize","640x480",outFile)
}

}

I think the likely issue is that ImageMagick isn't on your PATH. You'll need to restart your instance for it to pick up PATH changes, so this might be the root cause if you just installed ImageMagick. Could also be interesting to run with the /SHELL flag and see if that works.

Hopefully this helps!

It might be helpful to see the value of $zu(56,2) after the error occurs (if you continue to get <NOTOPEN>) - of course you probably don't really need to use STDIN/STDOUT and it might be cleaner to not.

In communication outside of this thread, turns out the issue stemmed from a failed %Save() - something like:

Class DC.Demo.OREFOIDDemo Extends %Persistent
{

Property Foo As %String(VALUELIST = ",Bar");

ClassMethod RunDemo()
{
    Do ..%KillExtent()
    
    Set thingOne = ..%New()
    Set thingOne.Foo = "Bar"
    Do thingOne.%Save()
    Set thingOne.Foo = "Baz"
    Do thingOne.%Save()
    
    // Later, and elsewhere, because thingOne happens to be in memory,
    // it appears that the value "Baz" has been persisted:
    
    Set thingTwo = ..%OpenId(thingOne.%Id())
    
    Write !,"thingOne = ",thingOne
    Write !,"thingTwo = ",thingTwo
    Write !,"thingOne.Foo = ",thingOne.Foo
    Write !,"thingTwo.Foo = ",thingTwo.Foo
    
    Write !,"thingOne.FooGetStored(thingOne.%Id()) = ",thingOne.FooGetStored(thingOne.%Id())
    
    Do thingTwo.%Reload()
    Write !,"After thingTwo.%Reload(), thingOne.Foo = ",thingOne.Foo
    Write !,"After thingTwo.%Reload(), thingTwo.Foo = ",thingOne.Foo
}

}

Which produces output:

Do ##class(DC.Demo.OREFOIDDemo).RunDemo()
thingOne = 15@DC.Demo.OREFOIDDemo
thingTwo = 15@DC.Demo.OREFOIDDemo
thingOne.Foo = Baz
thingTwo.Foo = Baz
thingOne.FooGetStored(thingOne.%Id()) = Bar
After thingTwo.%Reload(), thingOne.Foo = Bar
After thingTwo.%Reload(), thingTwo.Foo = Bar

If what you're describing is actually that a deep save isn't working, this might just be something else entirely. :)

Timothy Leavitt · Mar 8, 2021 go to post

If I understand what you're asking correctly, this is a really great question that hits on a kind of tricky aspect of ObjectScript/persistence. In short, if you already have a persistent object in memory (with a variable, say thingOne, assigned to it), and you open the same ID again and assign another variable to it (say, thingTwo), the OREF will be reused - both variables will point to the same object, and that one in-memory instance of the object can be modified via either variable. This can easily lead to some confusing scenarios.

Here's a quick demonstration of the fact:

Class DC.Demo.OREFOIDDemo Extends %Persistent
{

Property Foo As %String;

ClassMethod RunDemo()
{
    Do ..%KillExtent()
    
    Set thingOne = ..%New()
    Set thingOne.Foo = "Bar"
    Do thingOne.%Save()
    
    Set thingTwo = ..%OpenId(thingOne.%Id())
    Set thingTwo.Foo = "Baz"
    
    Write !,"thingOne = ",thingOne
    Write !,"thingTwo = ",thingTwo
    Write !,"thingOne.Foo = ",thingOne.Foo
    Write !,"thingTwo.Foo = ",thingTwo.Foo
}

}

Running the method produces the output:

Do ##class(DC.Demo.OREFOIDDemo).RunDemo()

thingOne = 18@DC.Demo.OREFOIDDemo
thingTwo = 18@DC.Demo.OREFOIDDemo
thingOne.Foo = Baz
thingTwo.Foo = Baz

It may surprise you that thingOne.Foo has also been set to "Baz" - but as you can see, thingOne and thingTwo reference the same object.

Note that if for some reason I wanted to know the current persisted value of thingOne.Foo, I could use:

thingOne.FooGetStored(thingOne.%Id())

I'll add - it should be an option (and in the HS package manager it is) to distribute some classes/routines as .OBJ and some with source within the same package.

Timothy Leavitt · Mar 5, 2021 go to post

@Evgeny Shvarov there's internal work in the HS package manager to support packaging as a studio project, which may optionally include deployed code. (I believe this didn't make it into the ZPM fork.)

The downside to this approach is that you may need different artifacts for different target platform versions. (It's always safest to assume that you do, at least on the major.minor level.) This would be a new design consideration in zpm-registry.

One possible upside to this approach is that it may be possible to install the build artifact even on environments that don't have the package manager. For the internal implementation we generate an INSTALL.mac that automates things from the different resource processor classes. Uninstallation is still a bit of a conundrum though; I think we'd be better off requiring the package manager for any ZPM implementation of packaging/installing deployed code.

I can think of one extremely valuable internal project that would only be palatable to distribute via ZPM if we didn't have to ship all the source (specifically, a Mockito-style mock framework for ObjectScript that breaks the glass on some internal things not shipped in product source).

Ah - this is actually messages.log on an IRIS instance. (It used to be called cconsole.log on older products.)

Do you see any messages like this in your messages.log?

Timothy Leavitt · Feb 24, 2021 go to post

Is forwarding cconsole.log an option? There should be a 0-severity message there like:

05/15/19-13:52:53:824 (2144) 0 cleaned dead job, pid: 4012, jobid 0x00010013

Given that SQLCODE is 100 (in other comment thread), might you have an index on %ConfigName that has not been built?

What do you see from the following queries?

select * from X_X.X where %ConfigName IN ('X_X_X','Y_Y_Y')

select * from %IGNOREINDEX * X_X.X where %ConfigName IN ('X_X_X','Y_Y_Y')

Also, is X_X.X the table corresponding to the class where the property is defined?

Timothy Leavitt · Jan 29, 2021 go to post

Short answer: yes, ZPM can manage whatever you want other than ObjectScript, it just takes a little extra work.

Longer answer:

This "extra work" involves writing a class that extends %ZPM.PackageManager.Developer.Processor.Abstract and overrides OnBeforePhase or OnAfterPhase, then implementing whatever behavior you want. You can see a bunch of classes in the %ZPM.PackageManager.Developer.Processor package that do this.

I'd imagine being able to put something in the Resources element of module.xml like:

Where MyPackage.AptGetInstall overrides OnAfterPhase and for the "Activate" phase runs apt-get install <name of resource following "/external-dependencies/"

The catch:

If you want to support all operating systems, think about what the Windows equivalent would be and/or add defensive coding to avoid trying to run the command on Windows.

Here's how I'd typically do something like that, going back to my example from one of your earlier questions and expanding a bit. The persistent class as a new %Boolean property named "Toggleable" (not a magical name - you can call it whatever you like), and the tablePane has <column> elements added. The query supplying data for the table has the ID and Toggleable columns added as well. The "Toggleable" column has OnDrawCell defined to provide custom HTML for the cells in the table; this references an ObjectScript method (which doesn't need to be, and in fact shouldn't be, a ZenMethod). That ObjectScript method renders HTML which calls a ZenMethod to actually do the update, using query results from the %query variable (which is a special thing that's available for use in OnDrawCell). No table refresh is needed, but if you refresh the page you'll see that the checkbox values have indeed been persisted.

Here's the Zen XData change:

<tablePane id="myTable" OnCreateResultSet="CreateResultSet" valueColumn="ID">
<parameter value="" />
<parameter value="" />
<parameter value="" />
<column colName="ID" hidden="true" />
<column colName="Name" />
<column colName="SomeDate" />
<column colName="Toggleable" OnDrawCell="DrawToggleCell" />
</tablePane>

And corresponding ObjectScript methods:

/// Note: this doesn't need to be a ZenMethod.
ClassMethod DrawToggleCell(pTable As %ZEN.Component.tablePane, pColName As %String, pSeed As %String) As %Status
{
    &html<<input type="checkbox" #($Case(%query("Toggleable"),1:"checked",:""))# onchange="zenPage.Toggle(#(..QuoteJS(%query("ID")))#,this.checked)" />>
    Quit $$$OK
}

ClassMethod Toggle(pID As %String, pValue As %Boolean) [ ZenMethod ]
{
    Set obj = ##class(DC.Demo.SampleData).%OpenId(pID,,.sc)
    $$$ThrowOnError(sc)
    Set obj.Toggleable = pValue
    $$$ThrowOnError(obj.%Save())
}

Here's the full sample:

Class DC.Demo.SampleData Extends (%Persistent, %Populate)
{

Property Name As %String;

Property SomeDate As %Date;

Property Toggleable As %Boolean;

}

Class DC.Demo.ZenPage Extends %ZEN.Component.page

If the CSPGateway is configured properly you should certainly be able to make a REST request to the webserver rather than needing to use the private webserver port. Reading this again I think the issue isn't the header you saw but actually is mixed content - see e.g. https://www.howtogeek.com/443032/what-is-mixed-content-and-why-is-chrom…

In the browser developer tools this will show up as:

So you really need to make the request via https - which is what you said in the first place, of course! And the best way to do that will be via your IIS webserver, which might already be configured correctly, and (if it's not) can be configured using the instructions I linked to above.
