The documentation for the Read method says "Some stream classes use this to optimize the amount of data returned to align this with the underlying storage of the stream." I take this to mean that for a file stream, it might be trying to read in a way that aligns with how the drive is formatted. Can you run the command below and see if the Bytes Per Cluster is 1024?

Is SMTP authentication enabled in the Microsoft 365 account? That setting is turned off by default for new clients. You can check the setting in the Microsoft 365 admin portal under your active users.

That shouldn't matter since the tasks themselves are not always stored in the namespace in which they are run. They are stored in IRISSYS. Does the user you are logged in as have permission to edit the %SYS.Tasks table in the IRISSYS namespace? And is this a system task? (System tasks cannot be deleted.)

If you use a dataCombo, the first column of the SQL query is the actual value of the dataCombo and the second column is the display value. So if you defined a dataCombo with sql="select Analyst, Analyst->Name from Analysts" (or whatever your table is) you'll get what you want.

In that case, you'll also want to define the sqlLookup property of the dataCombo. That tells the Zen page how to find the correct display value when the value of the control is changed programatically, so something like "select Analyst->Name from Analysts where Analyst=?"

Does $ZV not meet your needs? I see you used it for your post, and it includes the build version, too.

David Hockenbroch · Oct 14, 2024 go to post

Inside your combobox, you can define a displayList and valueList. If you do that, you don't have to also define the options individually.

Thank you, Guillaume! Lesson learned: make sure you're running pip from the IRIS Python, not the default Python on the PC!

David Hockenbroch · Oct 11, 2024 go to post

Performance is number one for us. With properly defined and tuned tables, I've never seen a database run its queries faster than IRIS.

Also just a lot of native capabilities. It's pretty rare that we have to reach outside of what comes in the box. And now with embedded Python, when we do need to add something, we have a lot of options.

Aside from Python's technical benefits, there's also a personnel consideration. More and more younger developers are learning Python, and according to the PYPL index Python passed Java in popularity among learners in 2018 and is far beyond Java today. That means having Python as an option opens up your hiring pool more than any other language to the next generation of developers.

Yes, you can do that, but I have another recommendation.

You generally want to be careful with what you do in %SYS, and you might not want a user to have permission to access that stuff all the time. You could create a new security role that gives the right permissions to access whatever you're accessing, then assign it in that method, run the code that needs it, and remove it. So let's say your new security role is called MyRole:

set $ROLES = MyRole
set oldns = $NAMESPACE
new $NAMESPACE
set $NAMESPACE = "%SYS"
// Do your stuff here.
new $NAMESPACE
set $NAMESPACE = oldns
new $ROLES

The $ROLES special variable is used to manage roles that are added and removed programatically during the execution of code, but does not affect roles assigned to the user in the management portal.

If you don't have any other criteria you can use in your where clause, that will happen. Based on the data you've shown us, you'd need either ProvId or ProviderType to get it down to 1 row.

If you just want the first row returned and don't really care which one it is, you could do

SELECT TOP 1 IdentityId 
FROM PhysTable 
WHERE ProviderName = 'DOE, JOE' AND Type = 'NPI' 
ORDER BY IdentityId

But that's only if you always want the lower number, and I doubt that's the case, right?

David Hockenbroch · Oct 9, 2024 go to post

I think I'm confused. In your previous comment you said "We do not get the ProvId "8252" in the message, we do get the IdentityId "345678"." So I thought you got the IdentityId in the message.

David Hockenbroch · Oct 9, 2024 go to post

So you get the IdentityId and the ProviderName, and you know the Type, and you want to write a query to get the ProvId?

David Hockenbroch · Oct 9, 2024 go to post

Do you mean you want to know how to get just that column?

SELECT IdentityId
FROM PhysTable
WHERE ProviderName = 'DOE, JOE' AND type = 'NPI' AND ProvID = '8252'

Or if this is in SQL embedded in ObjectScript:

&sql(SELECT IdentityId INTO :IdentityId FROM PhysTable WHERE ProviderName = 'DOE, JOE' AND type = 'NPI' AND ProvId = '8252')

That will get the Identity ID and put it into the variable IdentityId for you to use in further code.

When you're using a REST API, you're sending an HTTP or HTTPS response, so all of the typical HTTP headers apply. This includes the content type and the disposition header. The content type, as Rodolfo mentioned, can be set using %response.ContentType. Others can be set using %response.SetHeader.

Just FYI, CSP sessions are instances of %CSP.Session. You could do ##class(%CSP.Session).%OpenId("wuuZ2Gwgxw") to get the session and use some of the properties and functions there to get more information on what's going on. And since they extend %Persistent, you can also use %DeleteId (at your own risk, of course).

If you are looking for the class name where a currently-running method originates, you could also try:

	set method = $CLASSNAME($THIS)_"||"_$P($Stack($stack,"PLACE"),"+",1)
	&sql(select Origin into :origin from %Dictionary.CompiledMethod where ID1 = :method)
	w origin,!
David Hockenbroch · Aug 23, 2024 go to post

Are you trying to get all of the classes that a class extends? You can do that like this:

	set classname = $CLASSNAME($THIS)
	&sql(select primarysuper into :super from %dictionary.compiledclass where id=:classname)
	w super,!

If you do that, super is a ~ separated list of the class and everything that it inherits from, which is probably actually more information than you need.

Glad you got an answer to your main question. To answer your other question about how to check a status, the Execute and Prepare methods of the %ResultSet class return a %Status. Where you have do Rs.Prepare(SQL) and do Rs.Execute(), you could use:

set sc = Rs.Prepare(SQL)
if $$$ISERR(sc) {$$$ThrowStatus(sc)}
set sc = Rs.Execute()
if $$$ISERR(sc) {$$$ThrowStatus(sc)}

Then if there was an error doing either of those things, it would get passed off to your catch block. In your case, there would've been an error indicating your permissions issue.

No, it doesn't run as soon as the previous task ends. It runs at the next scheduled time. So in my example above, if your task runs at 12:00:00 and doesn't finish until 12:01:30, the next scheduled time is 12:02:00, so that's when it'll run next. I'm not sure how far back in versions this goes, but you might be able to change that behavior so it's more like what you're expecting.

A task expires if it can't run when it was scheduled. This could be because your Ensemble instance was down when the task started, or it could be because a previous instance of the task was still running when it was supposed to start again. For example, if you have a task set to run every minute but it takes the task 90 seconds to complete, then when it run at 12:00, it will be supposed to start again at 12:01, but since it will still be running, the 12:01 task will expire and the task will run again at 12:02.

Also note that if you do it this way, your tag for the custom component will be RC:imageclickbutton with the XML namespace and a colon on the front.
