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

Hello,

I've got a table with many attributes and data. There is 10 000 000 registrations approximatly.

I need to make a research on this table with filters, paging, and order.

You can see an example of my SQL request :

SELECT * FROM ( SELECT TOP ALL * FROM ANCV_Data.Titre WHERE etatTitre = 'Emis' ORDER BY numRemise desc) v WHERE %vid BETWEEN 1 AND 25

Cause there are many data on my table, my SQL req is too long if I don't have index on my attributes BUT there are many associations possible...

Hello Community,

SQL language remains the most practical way to retrieve information stored in a database.

The JSON format is very often used in data exchange.

It is therefore common to seek to obtain data in JSON format from SQL queries.

Below you will find simple examples that can help you meet this need using ObjectScript and Python code.

How can we insert into a table using a stored procedure?

Table structure :

CREATE TABLE SampleHospital (
Hospital VARCHAR(50),
Location VARCHAR(50),
UserName VARCHAR(50),
UserFullName VARCHAR(70),
LastLogin TIMESTAMP,
LoginCount int)

Procedure Name:

call Custom_MENS_Other.samplesp('2021-11-02','2021-11-04','H001')

In Episode 4 of Data Points, we welcome @Benjamin De Boe to the pod to discuss some of the things you can do to optimize your SQL queries in InterSystems IRIS. We've all heard — either from ourselves or from others — the "this runs too slowly" complaint. I thought Benjamin did a great job walking through many of the things within IRIS you can look at with your queries to see what can be improved.

Hello,

Do you know if there is any way to disable the automatic tuning IRIS is doing every time a class is altered? It just takes too long in our case and is holding the system, so I'd like to tune the tables when I decide it (again).

I've seen in the documentation that for 2023 version there is an option present in the backend. But not for 2022, so I assume a flag is needed somewhere.

Many thanks!

HI *,

So last night I was doing a deployment which had a query to select from a large dataset of joined tables, to iterate through and populate data in a new table.

This was done in a classmethod using embedded SQL and the %PARALLEL keyword.
On a testing environment with the same dataset, this worked perfectly a few days earlier.

I try to create a column with computeonchange.

Its works with CREATE TABLE sql command, but if i use ALTER TABLE ADD COLUMN sql command this computeonchange doesn't works.

any reason why?

example:

CREATE TABLE MyStudents ( Name VARCHAR(16) NOT NULL, surname VARCHAR(16))

alter table MyStudents add column fullname Varchar(50) COMPUTECODE { SET {fullname}={Name}_ "?" _{surname}} COMPUTEONCHANGE (Name,surname)

insert into SQLUser.MyStudents (Name, surname) values ('name1',null)

update MyStudents set name = 'name' where name = 'name1'

A framework yes, but a suitable framework

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.

More than 1 cursor in a class

I have a class that has 2 different cursors for different queries, audit1 and audit2. which are in 2 different methods. The first query runs fine, but the second one generates a 102 error.

Is there an issue with having more than 1 cursor in a class?

Has anyone seen this before?
