#ObjectScript

InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.

Documentation.

Using VECTOR_COSINE() in SQL query to perform a text similarity search on existing embeddings in a %VECTOR column.

Code is below.

Commented out sql query returns this error: SQLCODE: -29 Field 'NEW_EMBEDDING_STR' not found in the applicable tables^ SELECT TOP ? maxID , activity , outcome FROMMain .AITest ORDER BY VECTOR_COSINE ( new_embedding_str ,

Sql query as written returns ERROR #5002: ObjectScript error: <PYTHON EXCEPTION> *<class 'OSError'>: isc_stdout_write: PyArg_ParseTuple failed!

What are the differences between a process private global and a percent variable? Basically I have some code running in an Ensemble operation that processes requests, and it needs access to pieces of data that are scattered throughout XData blocks in various classes. Rather than opening the XData object and deserializing the XML on each request, I opted to cache this data in a percent variable, something like:

set %MyVar(sub1,sub2) = myValue

Good day,

I would like to know how to detect in Caché ObjectScript if data saved in string is number and furthermore, if it's type is integer.

I maybe found a solution:

set value = "44.2d3"

try{
set status = $INUMBER(value,"")
if ('$FIND(+value,".")){
w "your variable: '"_value_"' is number and integer"
}else{
w "variable is number but no integer"
}
}catch(e){
w "variable is not number"
}

In my routine when I call set filestream.FileName = filename, I get an error

"cn_iptcp://localhost:56773/USER/%Stream.FileBinary.1.INT" does not exist on the Server

I successfully instantiate the %Stream.FileCharacter object. 'filestream' value is '1@%Stream.FileCharacter'. But when I debug the code, the step where I try to set the file name fails.

The port number for local host looks good for my current instance. I have tried a few variations, such as using the method FileNameSet(). But this did not work either.

Hi all,

I am trying to use some process private variables (percent variables) in Triggers.

I am referring to values from $System.Process, like the ClientIPAddress and CSPSessionID.
These do to not contain values and I suspect it is bacause of scope. I also checked, and the %session variable is not available if the change originated from a CSP request.
I know that in triggers the scope of the variables are to be kept local, that is why NEW is to be used.

I would like to loop through them and check if the date of birth is more than 2 years based on todays date

so I have ^checker("under2", "Eric David", "02-05-2018")

I want to check the birthdate based on todays date to see if it is greater than 2. How do I access the birthdate in the global

Please can you advice

Hello,

I don't know if the title is accurate enough. I have a legacy code that I need to optimize. It's a routine written in objectscript. It accepts 4 parameters and runs 6 nested FOR...$ORDER reading a big global.

The thing is when I run the routine the first time it takes around 60 seconds to run. If I run it again it takes 5 seconds. If I wait around 6 to 10 minutes to run it again, it takes 60 seconds again, but if I run it every 1, 2, 3... minutes it still takes only 5 seconds to run.

Hello everyone,

I am looking for the syntax or the way to use a class created in the "BNA" Namespace (my application) from the %SYS Namespace.

Here is the context:

I have a "BNA" application contained in the "BNA" NS, this application provides a user creation functionality. This feature creates both the user in a table in the application and in the Iris system.

Hello experts,

I’m working on an "Sort After" (]]) bug that I traced back to some weird behavior in ObjectScript. Perhaps someone can enlighten me…

The problem is as follows:

Let’s say we have:

Set A = “1.0”
Set B = “2.2”

If you execute the command ‘Sort After’ (]]), you get the following:

W A]]B
​1

…Which is wrong, A does NOT sort after B. The output should be 0.

If you set A and B to numeric values, it correctly outputs false (0):

set A = 1.0
set B = 2.2
​W A]]B

0

Has anyone called any outside Javascript code from inside their class files? I asked a long time ago if there was a way to manipulate an image within Cache Object Script, and since Cache doesn't have any image libraries its not really possible. However I have found Javascript to resize an image and wonder how hard it would be to mesh the two together.

Can anyone share any examples?

Thanks

Scott

I've created a scheduled task that dumps HL7 messages to flat files. It uses the OutputToLibraryStream() method of EnsLib.HL7.Message. I'd like to be able to run it on a mirror member host whether it's primary or backup.

When run against a database that's mounted read-only, it works fine. However, when I attempt to run it against a mirror backup database, I get the following error:

#5002: Cache error: <PROTECT>%LoadData+7^EnsLib.HL7.Message.1

Tracing that back to the source, I find:

We have a function that was written for us that allows us to create text files for logging certain aspects to the OS using %Stream.FileCharacter. We had no issues with this until we moved from AIX to Red Hat.

Now it seems the 1st time the function is called, and the file is created the permissions seem to be correct on the file. But as soon as we attempt to write another line to the file using MoveToEnd() it seems the permissions are changed on the file. I have been able to narrow the issue down to the MoveToEnd() by calling the function from different users.

ICMP/Ping with ObjectScript

Is it possible to "Ping" a remote host in IRIS for Health using ObjectScript? We host hundreds of TCP connections over hundreds of VPNs. I'm working on a project that would make it nice to have way to ping remove clients over the VPN to monitor connectivity and keep the tunnels alive.

Another thought/method would be to make an OS system call (AWS Linux), but I don't see a way to do that either.
