SELECT * FROM EMPLOYEE WHERE EMPID="005"

and the table data be like

In my previous article, Using LIKE with Variables and Patterns in SQL, we explored how the LIKE predicate behaves in different scenarios, from Embedded SQL to Dynamic SQL, and what happens to performance when wildcards and variables come into play. That piece was about getting comfortable writing a working LIKE query. But writing SQL that works is only the starting point. To build applications that are reliable, scalable, and secure, you need to understand the best practices that underpin all SQL, including queries that use LIKE.

This article takes the next step. We’ll look at a few key points to help strengthen your SQL code, avoid common pitfalls, and make sure your SELECT statements run not just correctly, but also efficiently and safely. I'll use SELECT statements with LIKE predicate as an example along the way, showing how these broader principles directly affect your queries and their results.

*This is what Gemini came up with for this article, kinda cute.

InterSystems FAQ rubric

This error occurs when an instance of the class is already open at compile time.

There are two ways to deal with this issue:

  1. Terminate the process or application that has the instance open
  2. Compile options in the studio build menu: Check the compile flag “Compile classes in use” and compile.

If you want to determine which process is using the class, try the sample routine below.

I'm trying to execute SQL on a EC2 via SSM:

                        EOF'
                       """
template = [line.strip() for line in template.splitlines()] 
template = """\n""".join(template) 
ssm_client = boto3.client('ssm') 
response = ssm_client.send_command(

Current triage systems often rely on the experience of admitting physicians. This can lead to delays in care for some patients, especially when faced with inexperienced residents or non-critical symptoms. Additionally, it can result in unnecessary hospital admissions, straining resources and increasing healthcare costs.

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:

I am trying to use postman to start the restapi classes from a json openapi2.0.0 file.

POST: https://myserver.com/api/mgmnt/v2/requestAPI. The body contains the openapi2.0.0. The application api/mgmnt has in security settings: password. JWT is not selected. I set postman authentication to basis authentication and gave username and password. I also set in headers IRISUsername and IRISPassword. I have 401 Unauthorized.

Is the only way to go through is to build an oauth token? or do I miss something?
