I'm getting wrapped around the axle with CAST and CONVERT and can't seem to find a way to do this (short of adding a stored procedure wrapping $zdt($zdth(posix,-2),3), which I'm refusing to do on principle, because there has to be some way to make this work).
Customers who switch to Caché from relational databases report that their average performance is up to 20 time faster, running on the same hardware, with no changes to the application. What is it about Caché that lets applications run so fast?
How can IRIS productions be deployed more quickly and with greater peace of mind?
The aim of interoperability productions is to enable you to connect systems in order to transform and route messages between them. To connect systems, you develop, configure, deploy and manage productions that integrate several software systems.
New to machine learning? Watch this video on InterSystems Developers YouTube to understand the basic concepts of machine learning and how it provides value in applications around the world today:

I noticed that a query called directly in a method of a class of a business operation does not return the same result as if I apply the same query in the same Caché database from Squirrel !!!
Is there way to set up an automated batch job in the Management Portal to execute an SQL query. Also, how can the related view be exported. I have executed the SQL queries and see the view and created files manually. I could not find any related documentation on the batch processes, but I thought batch or automated jobs could be set up via the Management Portal. Any information is appreciated...
There is a Link Procedure Wizard option within the Management Portal (System > SQL >Wizards > Link Procedure) which I had reliability issues with so I decided to use this solution instead.
The boss (reasonable intelligent ;-) wants to connect to the cache database through Excel, but unless I explain what he's looking for (field names DB names etc) then I can see him continually coming back for "what's the link here and how do I get the delivery company name etc etc"
is there a SAFE way I can give him access to our database using an intelligent visual user interface.
I had thought about the SQL Query Builder within the management portal, but the thought of giving him access to all of the other functionality of the management portal.

Presenter: Andreas Dieckow Task: Apply SQL security to multiple servers in a distributed system Approach: Provide code samples for using new API calls to apply SQL security statements to multiple instances of our products
Description: The requirement that started at all. See examples on how to use this new feature and integrate it into your application by discuss code examples.
Problem: SQL Security is local to the instance and most of time driven by customer application code. That it is only local to the instance and is not automatically going to other instances requires a solution.
Solution: With application code use new API calls to issue SQL security statements that is applied to multiple instances.

For volatile tables (tables with many INSERTs and DELETEs), storage for bitmap indexes can become inefficient over time.
For example, suppose that there are thousands of data with the following definition, and the operation of bulk deletion with TRUNCATE TABLE after being retained for a certain period of time is repeatedly performed.
Hello all; I am using a one-to-many relationship. I have a Claim (one), in a relationship with Lines (many), but the Claim is storing a list of Lines IDs, rather than the Lines storing the Claim Id. This seems upside down, and not what I expected.
I've two columns in my table and the type must be interval of integer values for example : age must be interval between [2 and 6] years and wigth between [10 and 30 ] Kg , how can i define them when creating my table?
I am trying to pinpoint and troubleshoot an issue we have been seeing lately. We have several SQL Outbound Adapter Operations that are seeing issues trying to connect to our MS SQL Servers using the JDBC Gateway for calling insert, select, update, and stored procedure calls.
It is common to test a connection sending a general SQL instruction to the database, in Oracle we send select 1 from dual, for example, and in IRIS what the best option?
Pandas is not just a popular software library. It is a cornerstone in the Python data analysis landscape. Renowned for its simplicity and power, it offers a variety of data structures and functions that are instrumental in transforming the complexity of data preparation and analysis into a more manageable form. It is particularly relevant in such specialized environments as ObjectScript for Key Performance Indicators (KPIs) and reporting, especially within the framework of the InterSystems IRIS platform, a leading data management and analysis solution.

A quick question regarding to SQL Query Plan: Why these two requests have different plans, in particularly, why second request needs temp file? To me, temp file is a bad thing which should be avoided, right?
select * from Test.Log where cdate = 1
select * from Test.Log where cdate > 1
Plan for 1:
Read index map Test.Log.cdateIndex, using the given %SQLUPPER(cdate), and looping on ID. For each row: Read master map Test.Log.IDKEY, using the given idkey value. Output the row.
I am currently using D $SYSTEM.SQL.Shell() command or management portal to retrieve the data from database. I just learned we can also run cache table sql queries in MS access. MS access already installed on my machine.
I need to ask how I can connect my database of USER or sample namespace in MS access to run these SQL queries.
