#ObjectScript

Hello Experts,

I have a silly question of using InsertParam method and usage. I understand it is name value pair. I am using GET method to send a url and to get the details from server. URL has multiparameter

URL - api/Identifier/Image/?Verify.EDD={EDD}&Verify.Ethnicity={ETHNICITY}

I have used the URL in a method and called that method directly in the business operation. I am using Insertparam method -

The following code snippet includes a class method "test" that runs code to find a class based on the class's name. "test" takes one argument, which is the name of the table:

Class objectscript.findTable Extends %RegisteredObject
{
    classmethod test(name as %String="mytable")  
    {
            #Dim result as %ResultSet
            #Dim tName as %String
            #Dim contain as %Integer
     
            Set contain=0
            Set result = ##class(%ResultSet).%New("%Dictionary.ClassDefinition:Summary")
            Do result.Execute()

            While(result.Next()) 
            {
                Set tName=$get(result.Data("Name"))
                &sql(select position (:name in :tName) into :contain)
                Write:contain'=0 tName, " ... ", name, " (", contain,")", !
            }
            Return $$$OK
     }
}

I can refer to the TracerName for a given ImageFile object with the following syntax: obj.Study.Injection.GetAt(obj.InjKey).RadioTracer.TracerName

Is it possible to write an SQL statement to search the PET.ImageFile table to find a match based on the RadioTracer.TracerName?

This code snippet allows for a file on the web to be saved into the file system. Specify the server and GET request, as well as the directory the file should be saved to. The class method "test" runs the code:

Class objectscript.saveFileHTTP Extends %RegisteredObject
{
    classmethod test() {
        Set httprequest = ##class(%Net.HttpRequest).%New()
        Set httprequest.Server = "docs.intersystems.com"
        Do httprequest.Get("documentation/cache/20172/pdfs/GJSON.pdf")
        
        Do $System.OBJ.Dump(httprequest.HttpResponse)
         
        Set stream=##class(%FileBinaryStream).%New()
        Set stream.Filename="c:\test.pdf"

        Write stream.CopyFrom(httprequest.HttpResponse.Data)
        Write stream.%Save()
    }
}

This code snippet changes all passwords in a system to a specified string. The two literal strings at the beginning of the snippet can be adjusted to edit the system or password string. The class method "test" runs the code:

Hello,

Currently, I'm working with a Java Gateway, and I have the following problem. When importing a class into IRIS, which uses methods from a generic class, I can not find the general methods I need. I'm talking about the test2 method from the class test. How can I import the java method that returns a generic?

Hello Everyone,

I was wondering about the best way to initialize several variables, or several lists of variables.

Would it be better to write it like:

set (var1, var2, var3) = "value1"
set (var4, var5) = "value2"
set (var6,var7,var8) = "value3"

or

set var1="value1", var2="value1", var3="value1", var4="value2", var5="value2", var6="value3", var7="value3", var8="value3"

or

Traditional Caché Objectscript has the multi-dimensional array as its main form of complex data structure and the $order command as the main means of traversing said data structures. But newer versions of Caché ObjectScript also have data structures that are direct parallels of what languages such as JavaScript provide, in the form of %DynamicObject and %DynamicArray. These have an easy to use iterator feature via the %GetIterator method, and even a handy built-in literal syntax for constructing new objects.

(Originally posted by @Eduard Lebedyuk on Intersystems CODE, 6/26/14) This code snippet determines the difference between two ObjectScript lists. The class method "test" runs the code, and its parameters are detailed in the comments:

The following code allows a user to view the audit settings of their instance. Run the code by running the class method "test":

Hi All,

Just wondering if anyone had got this working.

In the documentation it says to set the username and password properties of the connection object but these properties don't exist and without authentication I can't connect to the MQ queue.

Any help would be greatly appreciated,

I have a class that has a property calledTags (like DescriptiveWords, but tags), where multiple tags are possible. I am trying to decide on list of Objects vs. array of Objects.

Based on this post: https://community.intersystems.com/post/querying-list-property-sql, sounds like using an array of Objects is the better way to go. Indeed, I already noticed that it's not possible to have duplicates when using an array of Objects.

Hi,
it is possible to convert a csv file to json file?

I want to stream json files and output the data as it comes in from the files. So my files are "csv" type and I want to convert these files to "json" type.

I can read csv file as follows:

Hi everyone,

I am still learning the platform for a student project and have to do some streaming and data analysis next. Since for my case I have no "live api" I wanted to just stream json files and output the data as it comes in from the files. (basically to emulate a incoming data scenario)

So thanks to the documentation and community posts I have figured how to create a stream and read data from a JSON but since I'm also new to JSON I have some parsing problems. I don't know how to access subarrays/sub-objects via objectscript.
