In the previous part of this series, we saw how to include data in a portlet from within DeepSee. This used the built in data controller. In this part, we are going to be pulling in data from outside of DeepSee. This will include both information from within InterSystems IRIS and from the OS.
Why use this?
This is useful if you would like to create a dashboard that only contains information about your system. It is also useful if you want to display data about your system along side data that you have stored in DeepSee.
Some may think it's a strange / daft idea, but just today the Raspberry Pi folks have announced that they've now sold more than 10 million of them..and counting. That's a huge potential marketplace, and a great platform for getting people to hear about Cache and try it out. Given its focus on the education sector, another great way of getting heard about.
When using Related Cubes in InterSystems IRIS BI, cubes must be built in the proper order. The One side must be built before the Many side. This is because during build time for the Many side, it looks up the record on the One side and creates a link. If the referenced record is not found on the One side, a Missing Relationship build error is generated. The One side is going to be the independent side of the relationship, AKA the side of the relationship that is referenced by the Many side or the Dependent cube. For example: Patients contain a reference to their Doctor.
Have you ever needed a math function but could not find what you needed and ended up writing your own? Look no further! ObjectScript-Math is here to solve all your math related function needs.
ObjectScript-Math is an Open Source library for ObjectScript Math functions. It is now available on Open Exchange. This library contains a mix of new functions that are not currently available and functions that are available. The existing functions will be wrapped for use from ObjectScript-Math so that all Math functions can have a central location.
This library will continue to grow, so give it a try and give your feedback!
Don't see what you are looking for? Please feel free to submit requests for additional functions or contribute code yourself!
I've writing a short classmethod that extracts an HL7 message from EnsLib.HL7.Message by ID and returns it as a stream. It's to be called as a stored procedure via ODBC (or ADO.NET) to fetch messages into an application.
I'm not using an SQL query in the classmethod itself, but it will be called as part of an SQL query via ODBC, but I can't figure out how to set a custom SQLCODE and error text from within the classmethod that propagates back to the external application. I thought %sqlcontext would be useful for this, but it doesn't appear to do anything. Here's the class:
I use the 2012 version of the caché, and I need to export data in an Excel file, the point that seems to complicate is to use the dropdown list in the cell and then trigger a validation if I exceed an interval of two values.
Intersystem Cache is a commercial operational database management system from intersystem, used to develop healthcare management, banking and financial, government sectors software applications.
Is there a way to get a good performing index on a date field? I have tried various date property indexes and the query plan is always in a pretty high range. Below are query plan result values I have observed:
StartDate > '2019-12-01' --cost = 699168 StartDate = '2019-12-21' --cost 70666 StartDate between '2019-12-21' and '2019-21-28' --cost = 492058
I am working on Files where I have to compare contents of two files and display result.
e.g Suppose file1 contains data in Name and Roll form and file2 contains data in name and class form, so it should compare name from file1 and file2 and display those matching data(Name,Roll,class).
I have piece of idea about file system so any help would be appreciated.
Thanks in advance.
I have written a procedure with the help of object scripting to export data to a csv file. There is more data than the csv limit.
Can anyone please tell me how to get the row count of csv file using object scripting, so that I can write an if condition and write to a second csv file.
Please find the code writing to the csv given below.
In the previous part of this series, we saw how to reference a web page that will enhance our dashboard experience. Now we will look into referencing data that is already in our cubes.
In this example, we will be referencing the controller object and we will be extracting data from it. This data will then be displayed as text in our Dashboard. In Part 5, we will show how to incorporate this data into other charting libraries.
I am trying to use the %ListOfDataTypes functionality, but am hitting a limit of 50 characters for each entry, when being used in a Web Service. Is there a way to increase the number of characters that can be used in the %ListOfDataTypes through a web service?
I am trying to do a basic read file of HL7 messages. Need to count how many FT1 segments are there in each file and how many messages are in each file.
Any help will be appreciated. I have the stream object.
Just need to loop through the stream and get the info in some way.
Does anyone NOT use a debugger? I can't remember the last time I did. It's not because I don't dislike them, I just don't need to use them. The main reason for this is because I have a certain development methodology that either produces less bugs, catches them at a unit test level, or makes tracking them down much easier.
I am planning to build a WebApp that will have tons of data to display in tables, ability to add comments on that table rows and may be some few more small features as we move on.
1. It has to be Secure
2. It has to be fast
3. It has to be Non CSP / Non Zen
4. Will have Cache DB to pull records from but should be flexible to do that from any odbc resource
5. Version 2018 Ensemble
My first step would have been to investigate different options for technologies that would make it work and best suited with Ensemble 2018
Does anyone know of an API that will do a hostname look-up based on IP? We could of course use call-out but the format of the results vary based on OS and if there is already an ObjectScript tool which will parse this then we'd rather use what is already available.
I trying to get the DisplayList data of the ValueLIst from Java using Springboot. when I try to get the DislayList data via java code but I'm getting the VALUELIST data. I don't get any idea to get that DisplayList data. Below is the example
Lately, you have probably heard of the new InterSystems Package Manager - ZPM. If you're familiar with it or with such package managers as NPM, Dep, pip/PyPI, etc. or just know what is it all about -- this question is for you! The question I want to arise is actually a system design question, or, in other words, "how should ZPM implement it".
In the first article I started discussing RESTForms - REST API for your persistent classes. We talked about basic features, now, I'd like to discuss advanced features - mainly queries capabilites:
Basic queries
Query arguments
Custom queries
Queries
Queries allow getting slices of data, based on arbitrary criteria. There are two query types in RESTForms:
Basic queries work for all RESTForms classes once defined and they differ only by the field list
Custom queries work only for the classes in which they are specified and available, but the developer has full access to query text
I've been having a blast with the Advent of Code puzzles this year - though I'll be heading into a busy span of time with family soon and will probably drop off toward the end. (At least, that's what always seems to happen - it's a good thing, though!)
We need to develop a small csp application which shows data in simple paginated / searchable table for business users.
It is to be built on an old version of Cache and is not a big full fledged application but something temporary. We can't use Zen and using a combination of csp & Bootstrap as bootstrap makes the pages look beautiful with little effort.
I have built the table in boostrap and it works fine with pagination and search working perfectly
In the previous part of this series, we saw how to define a basic portlet. Now we will look into making this portlet reference a web page that will enhance our dashboard experience.
In this example, we will be embedding a Developer Community article along side a couple of widgets displaying information related to the number of views on the Developer Community articles. This example is not hosted on the Community Analytics server, but if it was we could see the view counts going up as we interacted with the page.
Why use this?
In a real case, perhaps you have an embedded page from an external web site showing the current Emergency Room wait times for Hospitals in your area. This portlet can be used along side widgets from your Emergency Room showing how many people are waiting, how many doctors are active, and how many people are being treated. As other Emergency Room wait times grow, you can possibly expect your volume to increase as well. This can help you make decisions on how to allocate resources.
