#SQL

Instead of building a BP to execute stored procedures just to insert the data, I figured I would give Linked Stored Procedures a try since all I need to do is insert the data. I have proved in our MS SQL Development environment that it is possible, so I through I could just repoint the Linked Stored Procedure

I am attempting to create a Foreign Server/Table so I can pull some information in from MS SQL server via JDBC connection, but as soon as I create the Server/Table and logout the Foreign Server disappears.

CREATE FOREIGN SERVER Epic.Clarity 
   FOREIGN DATA WRAPPER JDBC CONNECTION 'MS-EpicClarity'

logout, then run

First time trying to use Foreign Tables/Servers instead of Linked Tables...

Within the SQL Editor inside of the Managment Portal, or connecting through DBeaver JDBC how we can see what Foreign Servers have been defined? Is there a way to query and verify structure of the Foreign Server connection to know that we are building the correct Foreign Tables?

I attempted to create my first Foreign table but it failed when I tried to query the tables because it said the table could not be found. But when I sign into the Database via SQL Management Studio, I can see the table.

Hello everyone,

I’m facing issues with replicating data from my Caché 2016 database to a PostgreSQL database. I need to handle around 300 data updates per minute, and whenever certain tables are modified, those changes must be reflected in other databases.

So far, I’ve tried various approaches, including:

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.

Hello,

Our software commonly returns a full result set to the client and we use the DataTables plugin to display table data. This has worked well, but at datasets grow larger, we are trying to move some of these requests server-side so the server handles the bulk of the work rather than the client. This has had me scratching my head in so many ways.

I'm hoping I can get a mix of general best practice advice but also maybe some IRIS specific ideas.

Some background

I'm playing with some anayltic queries against FHIR server tables. The HSFHIR_X0002_S_Patient.addressCity table contains a lot of cities which names contain german charachers such as ä, ö and ü.

The following query works fine:

select value from HSFHIR_X0002_S_Patient.addressCity

But this one converts city names to uppercase, and characters with umlauts are lost, so instead of "Köln" or "München" I see KOLN and MUNCHEN:

I am using a JDBC connection to MS SQL server to execute a stored procedure to select data and bring it into InterSystems as a EnsLib.SQL.Snapshot. I loop through the EnsLib.SQL.Snapshot using a while loop, but I also want to iterate through the Columns within that Row to do logic.

Is there a way to iterate through the Columns of the current Row of the EnsLib.SQL.Snapshot so I can apply logic/rules for further processing?

Thanks

I am struggling with returning a SQL Query Result that may have multiple rows that can be searched.

I have an IRIS persistent class with a %Stream property whose value is a JSON object. I'd like to use a SQL trigger to pull some value out of the JSON and persist it in another property, for easy querying and indexing. See below for a minimal example:

How would you go about creating an SQL Stored Procedure that would result in the same output as "IN LIKE"?
For example...


CustomersTable

I am currently experiencing frustration with trying to Authenticate an Active Directory account through JDBC as the Hospital System moves from OnPrem SQL Server to using Azure SQL Server with Microsoft Entra Authentication.

Microsoft cannot give me a straight answer of what is required from a JDBC standpoint to authenticate from a Linux environment.

Hello Community,

I executed the below query in the %ZLANGC00.mac routine. It returns results when using dynamic SQL, but not with embedded SQL(returns 0).

Hi community.

I was wondering if it was possible to use something like EnsLib.SQL.InboundAdapter with tables in IRIS.

This library monitors when a record has been inserted into a table in an external database, so it requires a DSN to connect to that database.

My goal is to make a call to an external API that takes a long time, it could spend nearly an hour (or more) completing its processes, but I don't want to block the main process.
