SQL is a standard language for storing, manipulating and retrieving data in relational databases.

Following instructions on this page https://docs.intersystems.com/latest/csp/docbook/Doc.View.cls?KEY=D2IMP_... I am trying to create a Data Connector to be used as a base class for a cube with update support.
That page suggests that putting an SQL query inside XData block is not suitable for a Data Connector that supports updates.
Later it also suggests that to enable updates your SQL query must include

Dear Experts,

I have to pull out a report of certain code tables and this is my first script and I need to write many.

1. If I have to refer to the table, seeing the reference in the components with reference to SQL table and column,

can I use Select < What I need from the table>

Inner join with reference table?

I tried, I used the code table reference in the components, but I am getting errors,

Hi!

I have a question regarding SQL insert/update from the mananger portal's SQL window.

I am trying to do an insert with a value that contains multiple spaces ($32) between two words. This is needed for a comparative reason. But the spaces are automatically trimmed away all the time. How should I write to keep these?

Example:

Insert into TableA
(MyColumn) Values('xxxx yyyy')

then the spaces are trimmed away and it becomes: 'xxxx yyyy'

But I want to keep the spaces. How do I get around the problem?

Regards,
Michael

In Cache 2018, we were using a macro in a query that looked like this:

select $$GetExtraSQL^GetExtra('B',bddtl.odnumb,bddtl.odsnum,bddtl.oddsc1) as "Description", * from sqluser.bddtl

We could save that query as a view, and there was no problem with it.

In IRIS, if we put that query into SQL in the management portal, it still works, but if we save that query as a view, when we try to run a query on that view, we get a big error message:

Hello!

I'm new to the system I'm working on, and I have a part of a statement that needs to grab the previous month.

....and MONTH(TX3.date_of_service)= MONTH(dateadd(mm,-1,GETDATE()))

However, when it hits January, I'm left with month 0.

Does anyone know a workaround to grab December of the previous year, while still functioning normally for the rest of the current year.

Thank you!

In show Query messages in the message viewer the head.%Id is always used. How do you do this via your own sql/objectscript as fast as the portal does a search as using dates searching Ens.MessageHeader on portal is slow.

For instance if you try do a search saying (TimeProcessed >='2023-06-01 00:00:00.000' and TimeProcessed <'2023-06-02 00:00:00.000') it is slow but using the portal the search would know this is head.%ID >= 5344549861 AND head.%ID <= 5347641372. How do you utilize this in your own queries as can't see the logic in EnsPortal.MsgFilter.Assistant

Hi,

The system I am working on processes large numbers of records. Inserts, updates and so forth. There are multiple processes that can potentially work on the same table at the same time.

It is an almost impossible task to try and time these processes to not run at the same time, due to volumes, SLAs, etc.

Every now and then there are a few locking issues, Not many considering the volumes. It is just a bit of a nuisance as we need to reprocess these records later.

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

Hi,

I'm trying to perform a SELECT with parameters using the EnsLib.SQL.OutboundAdapter. The SELECT returns results but seems to discard the parameters I try to send. I have tried two methods.

First:

Set par(1) = "20160630"
Set par(1,"SqlType") = 12
Set sql = "SELECT Cod, Ing, score FROM [bbdd].[dbo].[vw_Test] WHERE MyParam >= '?'"
Set tSC = ..Adapter.ExecuteQueryParmArray(.QueryResultSet,sql,.par)

Second:

Hello Fellow Cache Developers:

Has anyone ever created an index on values of a list property? If so, would you be willing to share an example?

Also, feel free to offer input and suggestions regarding use of indexes on List values.

Here is my database scenario:

Parent Class:

PropertyA - %String

PropertyB - %Integer

Child Class:

PropertyC - %Integer

PropertyD - list of %Integer

We don't often use SQL within our org, which is mostly due to the performance issue we experience due to the quantity of data we are reviewing.

Aside from the standard performance measures for non-Caché databases, are there any recommended approaches when querying large tables?

The table would have roughly 50M records, but there are not a finite amount of sub-nodes.

Insert SQL

I am inserting rows in a table. This table is appearing in all namespace as I did global mapping.

So once I run insert command from a method, it insert the rows. When I run the same insert command from other namespace, it replace the existing data in table.

Insert command is same in all namespace but the data I m inserting is different.

Greetings,

I am working on the first of many triggers which will have identical code upon row insertion or update of a single column. According to the document I should be able to define a multiple-event trigger using Cache SQL/DDL.

Here is a link to the current CREATE TRIGGER documentation. Within the description section is the following paragraph:

ad hoc sql service

Hi everyone, I have a SQL service that is working fine, except I don't want it to run on a schedule or continuously. I'd like to only run when requested. Run once and then stop until another request. Is there anyway to set up a service like that?
