#SQL

Hello,

Is there a programmatic way (in ObjectScript) to determine if a string is an SQL reserved word (aside from using embedded SQL to try to name a property with that string and look for the error :-))?

Thank you,

Jean

i am trying to embed a dynamic SQL into Objectscript code , but the %NEXT() will return 0 , however when i copy the same query and run it in the SQL bit it will give me the result i want
the code :

Does InterSystems IRIS has a MEDIAN (or percentile) calculation in SQL?

I have been walking through this with a few team members and as such I thought there might be others out there who could use it, especially if you work with HL7 & Ensemble/HealthConnect/HealthShare and never venture out past the Interoperability section.

In the past, I've created custom SQL operations, but now I had something trivial to do, so I decided to take EnsLib.SQL.Operation.GenericOperation out for a spin. There's no example in the docs, so it was a little tricky. Here's what I ended up doing:

In my external database, I have 'mytable' with two fields 'id1' and 'id2'. Here are the pertinent Business Operation settings:

I am experiencing an issue while executing a stored procedure in InterSystems Cache. Here’s the procedure I created

Hello all,

I need help with coming up with a SQL query that pulls only one value. I have a case where two providers share the exact same name. Each has a different NPI number and IdentityTypeId. I tried the below query - output is also below.

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

In this article, we’ll dive into the inner workings of the database management tool, exploring the architecture and technologies that power it. Understanding how the application functions behind the scenes will give you insight into its design, how it manages databases, tables, and how the API interacts with data.

Problems with Strings

I am accessing IRIS databases with JDBC (or ODBC) using Python. I want to fetch the data into a pandas dataframe to manipulate the data and create charts from it. I ran into a problem with string handling while using JDBC. This post is to help if anyone else has the same issues. Or, if there is an easier way to solve this, let me know in the comments!

I am using OSX, so I am unsure how unique my problem is. I am using Jupyter Notebooks, although the code would generally be the same if you used any other Python program or framework.

How to add the following to a stored procedure (Cache Studio)
1. Select from a few tables and insert result into a TABLEA.
2. Then select data from the TABLEA, apply some SQL logic, insert results into TABLEB.
3. SELECT * FROM TableA
UNION ALL
SELECT * FROM TableB

In SQL, NULL data and the empty string ('') are different data. The method for setting and checking each is as follows.

Hello all,

On one of my team's systems, we utilize a business operation with the EnsLib.SQL.OutboundAdapter to make SQL queries to another IRIS system using JDBC. To authenticate the connection, we utilize a user account on the target system.

FOREIGN TABLES is a rather fresh feature in IRIS (2023.?)
So I was motivated to try something new by own hands.
Documentation of Foreign Table from File is a good starting point.
Also the related promotional video is fine to start with.
