Hi folks!

Do we have an embedded REST API in IRIS which accepts arbitrary SQL and returns data in JSON?

Or if anyone did something like this?

The idea is to have something like MDX2JSON but SQL2JSON.

Thanks!

I need to consume the content of ^SPOOL output over SQL.

^%SPOOL utilities don't look so promising

Is it planned that LOAD DATA takes into account several DATE/DATETIME formats with, for example, a parameter indicating the format used in the source data?

example :

LOAD DATA .../...
USING
{
  "from": {
    "file": {
       "dateformat": "DD/MM/YYYY"
    }
  }
}

Hello, I need to use IRIS to connect to an MSSQL base.
It has to be done via ODBC, I can't use JDBC at this time by client option.

I am trying to use Microsoft Driver
libmsodbcsql-13.1.so.9.2

But I can't, my attempts result in:
Connection failed.
SQLState: () NativeError: [11001] Message:

I have done all DSN configuration, and my configuration is listed in SQL Gateway Connections. I know it's working, because when I run a test with isql I have the information that connects to the bank.

Would like to know if there is an alternative or better way to paginate through a dataset using dynamic SQL than what I am using below. The problem is that as the potential pool of data gets larger, this code slows down to the point of not being useable. In analyzing each line of code below, it appears the slow down is related to the initial rset.%Next() iteration. Is there anything available which does not require a subquery/%VID such as a simple LIMIT/OFFSET?

My code is similar to :

s sql=##class(%SQL.Statement).%New()

Hi Community,

We need to export last 5 days Ens.MessageHeader data for a specific messages into file. I have written custom code to execute SQL query in object script.

Could somebody help me to iterate resultSet and write the data to text file.

I want to override the Get and Set methods of a class property. The class maps to a pre-existing global. The property is defined like so:

Property Invalid As %Library.Boolean;

with the property mapping to a node like ^GLOBAL(Code,"INVALID")=1
Code is a property in the same class.

The value can be 0 or 1 or the node might not exist. When it doesn't exist I want the value of the SQL field to come out as 0 (false).

I need to generate a DDL file from a .cls class that already exists, the idea is to create a mirror table in SQL. Is it possible to do this export or do I need to do the CREATE TABLE manually?

I have written below method inbound adapter myAdapter Extends Ens.InboundAdapter [ ProcedureBlock ] returns -400

On IRIS version 2024.1.0.262.0 I have a table that store streams as %GlobalCharacterStream.

But depeding on the blob being saved I get the error: [Error: <<MAXSTRING>]

Is it possible see the execution plan of a SQL sentence in IRIS?

Like this:

explain plan for
select  e.ename,r.rname
from    employees  e
join    roles       r on (r.id = e.role_id)
join    departments d on (d.id = e.dept_id)
where   e.staffno <= 10
and     d.dname in ('Department Name 1','Department Name 2');

That returns this:

I'd like to have an array as a parameter for a SQL 'WHERE... IN' statement. The array would be modified in javascript on the browser. Here's a simplified example:
