I have a table with a Varchar(max) column that I have created via the HealthShare SQL portal, and I see that in it's underlying class that column corresponds to a %Stream.GlobalCharacter
When I try to do a text search on that column (referenced as cd.Code in the example below) I get an error
I'm struggling to insert into a table, and it is baffling me. The insert statement is now very simple (I was using a complex INSERT SELECT statement but I'm trying to narrow down the problem).

In the good old days (tm) determining the size of the data, streams, and indices for a class/table was easy - you just ran %GSIZE and check D, S, and I globals respectively.
However, nowadays sharding, optimized global names, and indices in separate globals produce %GSIZE output looking like this:
Thanks to @Yuri Marx we have seen a very nice example for DB migration from Postgres to IRIS. My personal problem is the use of DBeaver as a migration tool. Especially as one of the strengths of IRIS ( and also Caché) before is the availability of the SQLgateways that allow access to any external Db as long as for them an access usinig JDBC or ODBC is available. So I extended the package to demonstrate this.
I would like to capture any NACK's that is sent back to the Operation. The Operation is already setup to "Save Replies/IndexNotOK's", but I would like to see if we can query Cache and pull those NACK's into an extract.

We need a web-based SQL tool to connect to Ensemble/Cache, that will offer more functionality than what the Management Portal offers. It needs to be web based, so that we can host it on a machine that has connectivity to the server via the superserver port. We (the devs and support) only have browser access to the environment via Remote Desktops, hence the requirement.
Has anyone gotten OmniDB to connect to Ensemble/Cache? If so, can you please advise on how to configure it?
Any other suggestions for such a tool are also welcome.
Sometimes we need to import data into InterSystems IRIS from CSV. It can be done e.g. via csvgen tool that generates a class and imports all the data into it.
But what if you already have your own class and want to import data from CSV into your existing table?
There are numerous ways to do that but you can use csvgen (or csvgen-ui) again! I prepared and and example and happy to share. Here we go!
Recently our team have been getting requests to pickup a large amount of data from API nightly (e.g. using ODATA to loop through pages) and placing that into MS SQL databases.
My question is, what is considered the best practice to get data from API and route to external SQL database WITHOUT persisting any messages/traces etc?
Is there a way to find the median in Intersystems Cache SQL? I know it is not available as an aggregate function. Also in SQL Server I could try something like:
SELECT
(
(SELECT MAX(Score) FROM
(SELECT TOP 50 PERCENT Score FROM Posts ORDER BY Score) AS BottomHalf)
+
(SELECT MIN(Score) FROM
(SELECT TOP 50 PERCENT Score FROM Posts ORDER BY Score DESC) AS TopHalf)
) / 2 AS Median
However, there is no PERCENT Keyword in Cache as well. Any suggestions?
I have a linked procedure class and SQL gateway setup and I can't seem to get any response, status or error from using the stored procedure, I think it must be something big I'm missing to not even get a status.
Can someone see what my problem is please, any help would be very much appreciated.
A question has come up that I am not finding the answer for.... Does the daily purge process re-index EnsLib.HL7.SearchTable or other SQL tables? In looking at the purge process documentation I am not seeing anything that mentions EnsLib.HL7.SearchTable. Do we have to manually constantly re-index tables that we create? For example I created another search table based off of EnsLib.HL7.Search table, will I need to constantly watch this as it grows? How do tables get index, is there some kind of mechanism that automatically does it, or are we responsible for indexing tables ourselves?
I'm using an embedded SQL statement with a a cursor-based Embedded SQL query that uses host variables in the where clause, however, what I'm doing doesn't seem to work. Can anyone help?
I'd like to know if there are any issues if an index is inserted into a table without running the %BuildIndices() method.
It's important to note that data inserted before the index is not important for retrieval, so it's not a problem data inserted before the index don't show up in queries.
The reason why I'm asking this is that I'd like to avoid index reconstruction on big tables which I need to inser such index.
Why when I use a SQL on the Cache, the condition between "the expression" and "the expression", not permite to me, delete the all ID of this data class?
We are trying to track down the source of Orphaned messages and noticed that we are unable to query EnsLib.HL7.Message with any kind of WHERE or ORDER BY clauses in our SQL statement.
I know EnsLib.HL7.Message is a system table, but is there a way we can add additional Indexes to the table to make the query run better/faster without affecting the system?

I'm new to cache, come from an oracle and sql server background. In oracle and sql server I could write basically a stored procedure like script and pass it in as text to the command to execute.
Example:
Below would be the _sqltext
DECLARE @Id INT;
select id into @Id from something;
if @Id = 9
BEGIN
do something
END
The _sqltext would work in sql server, what would be the equivalent for cache for it work?
I want to have a script that can run from the usual unix, linux, or aix command line. It has to be able to get into an irissession and use set statements to get data using sql. It seems like I'm in a catch-22. When I use the irissession SERVER command at the command line, I can't run a script. When I put the irissession SERVER command in a script, it won't run anything in the script after that.
My goal for this script is to get this information and put it into a file which I can then parse.
