#SQL

Hello Community,

I have couple of question about the DynamicSQL.

1. The %ObjectSelectMode is working perfectly in the DynamicSQL for the object property in direct query. However this is not supported for class query. Is there any way to resolve this / Get the object value for class query result.

2. What is the reason behind for a stored query prepared using %PrepareClassQuery() you must use the %Get("fieldname") method.

Class Samples.DB.NewClass1 Extends%Persistent
{
Property Address As NewClass3;ClassMethod TestQuery()
{ 
	set statement = ##class(%SQL.Statement).%New()
	set statement.%Obj

Hi Community,

In this article, I listed 5 useful SQL functions with explanations and query examples 👇🏻
These 5 functions are

• COALESCE
• RANK
• DENSE_RANK
• ROW_NUMBER
• Function to Get Running Totals

So Let us start with COALESCE function

I have run the query and got ORU^R03 message from SQL Editor and reprocessed the message, But pdf not opened and the base64 content looks truncated.

Is there a way to get full content from the message from query? Why the content is not visible in DB that I can see in Message Viewer?

Thank you so much for your time to read this,

Hey Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ InterSystems Cloud Services - InterSystems IRIS SQL & IntegratedML @ Global Summit 2023

The related package avoids adding %JSONAdaptor to each class but uses  instead   
SQL functions JSON_OBJECT() to create my JSON objects. With this approach, you can   
add JSON to any class - even deployed ones - without any need for change or recompiling.

The trigger was the Export of M:N relationships  as JSON  objects or arrays.

I need to run a SQL query and use the output to map PV1 7.1. The query is :

SELECT ID
FROM TestTable
WHERE ProviderName = 'TEST,PROVIDER' AND IDType= 'BPI'

When I run this query with the 'TEST PROVIDER'  I do pull the ID in question but I can't figure out how to do it from the DTL given that there are various providers sent in PV 1 7 . Any assistance will be greatly appreciated. 

Hi,

I am trying to find out individual segment values in Message viewer and it display the values in Management portal, copied the query and run it on SQL editor, Segment values displayed with blank. Is there a way to get the individual segment values using query?

Enhanced Password Management: Edit Passwords Seamlessly

In the ever-evolving landscape of digital security, robust password management tools have become indispensable. Our password management application, designed to simplify and secure your online life, now comes with an enhanced feature – the ability to edit passwords with ease.

Why is this feature a game-changer?

I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. This works well most of the time, but when I query a table to get data from particular fields that contain long text strings, it returns `NULL`. These fields are all `VARCHAR(30000)`.

I tried using the `$extract` functionality in the IRIS documentation, but that made no difference. I also tried setting the PHP setting `odbc.defaultlrl` to both 31K and 0. Neither resolved the issue.

I also looked through the internet to try and find a similar issue, but wasn't able to find anything

It can be retrieved using the schema INFORMATION_SCHEMA.

INFORMATION_SCHEMA is a system schema and is not displayed by default in the SQL menu of the Management Portal.

The method to display it is as follows.

1. Open Management Portal → System Explorer → SQL menu.
2. Check "System" on the left of the schema drop-down.
3. Select INFORMATION_SCHEMA from the schema dropdown.

The SQL to get the ID, field name (COLUMN_NAME), data type (DATA_TYPE), description (DESCRIPTION) for the specified table (Sample.Human) is as follows.

  If you're looking to get started with SQL in InterSystems IRIS or want to make your queries more efficient, try one of these short online learning exercises!

• Running Fast Queries with SQL in InterSystems IRIS (10m)
• Optimizing SQL Queries in InterSystems IRIS (15m)

Both include learning labs, so no need to bring your own instance. 

Currently, the SQL privileges (SELECT, INSERT, UPDATE, DELETE) are managed at the tables level, which can be very tedious when you have to administer many roles in an organization, and need to keep them sync with a constantly evolving data models.
By managing privileges at the schemas level, will allow to give SELECT and other DML privileges to *all* or *several schemas* to a role|user, fixing the need to manually synchronize the new tables|views to the roles.

If you agree, I invite you to vote for this idea.

In today's landscape, enterprises have grown substantially in scale, amassing vast amounts of data. This data is collected from a plethora of sources including different applications, databases, and other channels. Given the diversity and volume of this data, it's only logical for these enterprises to seek a deeper understanding of what their data entails. Some of the data can be stored in IRIS, and it can be reasonable to be able to add this data to a data lake too.

The Internet now offers many different tools for such tasks, that do not yet support IRIS, but it's achievable.

Hi all,
I am trying to execute a query like the below code.
set statement = ##class(%ResultSet).%New("some_class:query_method").   // here query method is empty and with rowspec some columname

statement.Execute(param1)

I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc.
How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3

Hi developers,

We have received quite a lot of interest in using SQL on FHIR data. As you know, FHIR data is encoded in the form of a complex directed graph, and thus you can not easily query it with traditional SQL queries or business intelligence tools. Some customers have noticed that the "FHIR search tables" in IRIS for Health have flattened part of the FHIR graph, and have tried to use them for analytics. This is an undocumented and unsupported part of IRIS for Health, and can change without notice.

The good news is we are working on a product supported feature for IRIS for Health to

after running a benchmark for 40 minutes, I have been asked if any rollbacks occurred in that time. Rollbacks from SQL or objects.

The application does not record this, so I am looking for a system level record.

The journal entries do the necessary reverse sets and commit just like any transaction. So i don't think i can detect them there.

The SQL documentation says "Messages indicating that a rollback occurred, and errors encountered during the rollback operation are logged in the cconsole.log", but when I deliberately write code and

The program below works perfectly when I call it directly from the Terminal, however when I call it from within a CSP it does not work (It does not do the SELECT).

Overview

The online documentation contains a reference Defining and Using Class Queries -

Customizing Stored Procedures with ObjectScript directly has been useful to access NoSQL storage and external messaging via integration, to present output in tabular format.

For example: An application that already uses 90% SQL interaction from a front end, can then also extend this access to the other 10% of required platform functionality, via the same SQL access.

The purpose of this article is to explore how to achieve the same effect via Embedded Python methods.

By specifying the start and end values ​​of the IDs for which you want to rebuild indexes in the arguments of the %BuildIndices() method provided in the persistent class (=table) definition, you can rebuild only the indexes within that range.

For example, to rebuild the NameIDX index and ZipCode index in the Sample.Person class only for ID=10 to 20, execute the following code (the ID range is specified in the 5th and 6th arguments). 

 set status = ##class(Sample.Person).%BuildIndices($LB("NameIDX","ZipCode"),1,,1,10,20) 

$LB() is the $ListBuild() function. The

Introduction

In some of the last few articles I've talked about types between IRIS and Python, and it is clear that it's not that easy to access objects from one side at another. 

Fortunately, work has already been done to create SQLAlchemy-iris (follow the link to see it on Open Exchange), which makes everything much easier for Python to access IRIS' objects, and I'm going to show the starters for that.

Thank you @Dmitry Maslennikov !

To install, simply open your terminal with administrators' access and type

pip install sqlalchemy-iris

and that will also install the pre-requisites for

The FHIR® SQL Builder, or Builder, is a component of InterSystems IRIS for Health. It is a sophisticated projection tool used to create custom SQL schemas using data in an InterSystems IRIS for Health FHIR repository without moving the data to a separate SQL repository. The Builder is designed specifically to work with FHIR repositories and multi-model databases in InterSystems IRIS for Health.

The objective of the Builder is to enable data analysts and business intelligence developers to work with FHIR using familiar analytic tools, without having to learn a new query syntax.

I'm looking for an efficient way in DBeaver to filter system tables (ex: belonging to a schema starting with "%").

By using a user with the %All role, DBeaver shows us a long list of system schemas, which forces us to go down the list before accessing the user tables.

I cannot get any further hint from the error message in red in this screenshot. Is there any clue or details about the connection failure that I could look for?

A bit of an old school CSP question.  <csp:search> is a really nice, quick way to make easy lookups for CSP pages, especially for back office stuff that doesn't need to look pretty for the modern web app user.

I found the thread that discusses object mapping, in particular mapping a common global among more than one namespace. The example that is given is a simple one when it's ^global(sub1, ^global(sub2, etc. However I'm having trouble getting this to compile/work when the global has a fixed subscript amongst variable ones.

I have this global in namespaces LAB and ARK in the following format:
^CB(1,sub1)=....

^CB(1,sub2)=...

^CB(1,sub3)=...

Here is what I have for this. In it's current state it throws tons of errors:
