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.
EnsPlus, the Caché Objectscript plugin for Visual Studio, has now been upgraded to support all versions of Visual Studio 2015, including the free Community edition.
I'm doing a REST service for integration between 2 systems. The system that invokes me expects a response object where only one of its attributes changes. It could be something like this:
I have a need to dynamically create a web application definition in a namespace using ObjectScript. I am having trouble finding a cache class or routine that let's me do this.
I am working on a BPL to take data from a MS SQL database and create an HL7 Materials Message for our EMR. I have done this plenty of times in the past however I am running into an error.
"Remote Gateway Error: JDBC Gateway SP execute(0) error 0: Access to the remote server is denied because no login-mapping exists."
What is confusing is that this BPL doesn't differ from any of my other BPLs in connecting to MS SQL Server. I know I am missing something..
I have a case where I need to look up the NPI provider against an External MS SQL database to retrieve our Provider Identifier to send to a downstream system. In the past I would use a Business Process (BPL) to connect to the outside MS SQL via JDBC and get that information for me. But I was thinking instead of creating a BPL process to do this, would it be better just to link to the outside MS SQL database table to retrieve the information in a SQL statement within a DTL?
We are looking for a 3rd party application that can scan our IRIS based Cache Object Script code for vulnerabilities or coding weaknesses. There are many, many applications/vendors out there that do code scanning but none seem to support Cache Object Script or scanning the IRIS environment. If anyone is aware of a company/product that can scan our code / IRIS environment, I would love to hear about it.
TL;DR: This article describes an introductory-level project that exercises some string-manipulation functions in both ObjectScript and Python…with specs from a song.
Suppose you have an application that allows users to write posts and comment on them. (Wait... that sounds familiar...)
For a given user, you want to be able to list all of the published posts with which that user has interacted - that is, either authored or commented on. How do you make this as fast as possible?
Here's what our %Persistent class definitions might look like as a starting point (storage definitions are important, but omitted for brevity):
I inherited some legacy MUMPS / ObjectScript code. A code review identified an exclusive NEW and that is not allowed per our coding standards.
The original code contains:
RUN(CALL,DRVNAME) S $EC="" S ^TMP($J,"RMPV","DRVNAME")=DRVNAME N TMPFILE,OLDIO S OLDIO=$IO I $G(^TMP("RMPV","SILENT"),1) S IOP="NULL",%ZIS=0 D ^%ZIS I '$G(POP,1) U IO D INIT^@DRVNAME D ; scope variables .N (DUZ,CALL) ; Protect %response .S IOF="""""",IOM=80,U="^" .D @CALL U OLDIO Q
If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.
Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance. %NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.
Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.
Is there any way that I can check the native type of an object script variable? (similar to the typeof check in javascript)
I see that the DynamicArray class uses the type of the variable for its output, I would like to do something similar when I receive a value as an argument to my method.
Is it possible to have a, b, c, d, e, and f as a counter instead of the counter being numeric? See below...Epic would like us to set OBX.4 using a alpha numeric combination.
My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.
The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:
For our WSDL the portType value is being suffixed with "Soap" at the end.
When i update the the SERVICENAME parameter. in the Service I can update the start of the portType value. Is there a way to prevent the suffix being added?
Using the Config.Configuration class and SYS.Database class methods, you can create and register a namespace database from the terminal.
Below is a series of execution examples that create database file /CacheDB/AAA/cache.dat and register database AAA and namespace AAA in the configuration file (cache.cpf). * Execute in the %SYS namespace. *
* Make sure that this script runs as the user that is used for all IRIS processes to ensure that the directory has appropriate ownership and permissions *
I have a list type data object, that has both null entries and locked entries. While iterating through the list items using GetAt() function, a locked item is satisfying the not null condition. But I need a different conditional statement for null items and locked items.
In ObjectScript you have a wide collection of functions that return some value typically:
set variable = $somefunction(param1,param2, ...)
There is nothing special about that. But there is a set of functions that I classify as LEFT SIDED The specialty of them is that you can use them also on the left of the equal operator as a target in the SET command:
Class Foo.Bar
{
ClassMethod Helper()
{
// do something
}
ClassMethod Generated() [ CodeMode = objectgenerator ]
{
do ..Helper()
// do something else
}
}
Since the method Generated is run before the class is compiled, the call to do ..Helper() fails. Is there a way around this other than manual inlining?
The Certification Team of InterSystems Learning Services is currently developing an InterSystems ObjectScript Specialist certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.
We have a vendor that every couple of days will just stop transmitting messages, but still hold the TCP/IP connection open. No matter how many times we troubleshoot and talk with them, they don't seem to think its an issue with system. Normally if I just restart the service it will get the data flowing again.
