Hi Developers,

New to machine learning? Watch this video on InterSystems Developers YouTube to understand the basic concepts of machine learning and how it provides value in applications around the world today: 

⏯ What is Machine Learning?

During runtime I build an object which is essentially a wrapper over in-memory table:

I want to use this object as a part of INSERT or UPDATE queries, based on a value of some column (the main use case one of the columns is an ID value)

What's the best way to expose the object to SQL?

When I describe InterSystems IRIS to more technically-minded people, I always start with how it is a multimodel DBMS at its core.

In my opinion that is its main advantage (on the DBMS side). And the data is stored only once. You just choose the access API you want to use.

• You want some sort of summary for your data? Use SQL!
• Do you want to work extensively with one record? Use objects!
• Want to access or set one value and you know the key? Use globals!

Hi,

Do you have any experience in inserting a panda dataframe into SQL IRIS Table? The dataframe.to_sql method uses sqlalchemy and it seems no dialect is available for IRIS.

thanks, Blaise

Hey Community,

my Caché Version: 2013.1 and can't update now.

is it possible to highlight SQL Statements like in embedded SQL with all the features from SQL Statements?

Actually I use SQL Statements with a simple string like:

set myquery = "SELECT TOP 5 Name,DOB AS bdate,FavoriteColors FROM Sample.Person"

But when the queries are more complex it will be very cluttered and unstructured.

It would be nicer if I could set line breaks (I know here could I use indexed variables) and have highlighting like in an embedded SQL:

&sql(

Best regards!

Hi Community,

We're pleased to invite you to join the upcoming InterSystems IRIS 2020.1 Tech Talk: Data Science, ML & Analytics on April 21st at 10:00 AM EDT!

In this first installment of InterSystems IRIS 2020.1 Tech Talks, we put the spotlight on data science, machine learning (ML), and analytics. InterSystems IntegratedML^TM brings automated machine learning to SQL developers. We'll show you how this technology supports feature engineering and chooses the most appropriate ML model for your data, all from the comfort of a SQL interface. We'll also talk about what's new in our open analytics offerings. Finally, we'll share some big news about InterSystems Reports, our "pixel-perfect" reporting option. See how you can now generate beautiful reports and export to PDF, Excel, or HTML.

Hey Community,

my Caché Version is 2013.1 and I can't update now.

I want to serialize a SQL Answer row into an Array filled with objects and then convert it to json.

Actually I use the following, which is very error prone when I have to do that often:

set list = ##class(%Library.ListOfDataTypes).%New()

       &sql(
            declare queryONLWK01 cursor for 
            select F0103, F0104
            into :articlenumber,  :amount
            from GL.ONLWK01
            where F0001 = :BET and F0002 = :DEB and F0003 = :MIT
       )
        &sql(open queryONLWK01)
        &sql(fetch queryONLWK01)
        while (SQLCODE = 0) {
            
            
            set articleObject = ##class(%ZEN.proxyObject).%New()
            
            set articleObject.articlenumber = articlenumber
            set articleObject.amount = amount
            
                do list.insert(articleObject)
        } 
    }

Hi,

I issue a sql like follow:

select *, %vid from (select * from order_info) where %vid  between 1 and 10

I got error

 [SQLCODE: <-400>:<Fatal error occurred>]

  [%msg: <Remote JDBC error: ORA-00911: invalid character >]

So ,what's the correct paging syntax for query external data?

Tks.

This is the first in a pair of articles on SQL indices.

Part 1 - Know your indices

What is an index, anyway?

Picture the last time you went to a library. Typically they have books sorted by subject matter (and then author and title), and each shelf has an end-plate with a code describing the subject of its books. If you wanted to collect books of a certain subject, instead of walking across every aisle and reading the inside cover of every book, you could head straight for the bookshelf labelled with your desired subject matter and choose your books.

I am experimenting with Relationships, both Parent to Child and One to Many.

I have done some SQL look-ups and have searched through the documentation, however not in a lot detail, but wonder if there are more and better ways to access both sides of Relationships through SQL?

Thank you in advance for any help provided.

InterSystems IRIS 2020.1 brings a broad set of improved and new capabilities to help build important applications. In addition to the many significant performance improvements accrued through 2019.1 and 2020.1, we are introducing one of our biggest changes in recent SQL history: the Universal Query Cache. This article provides more context on its impact to SQL-based applications at a technical level.

Hi ,

I have a code written in cache  sql and trying to understand it, below is the code , can anyone help me understand what does that mean 

ex - !! dosage_unit !!

SELECT (CASE WHEN (order_description IS NULL OR (order_description='')) THEN '' ELSE (order_description) END) !! (CASE WHEN (dosage IS NULL OR dosage_unit IS NULL OR (dosage='') OR (dosage_unit='')) THEN '' ELSE (', ' !! dosage !! ' ' !! dosage_unit !!

Thank You in advance.

Is there a way to query the database structure?  In SSMS there are queries for finding tables with a column with a certain name (using LIKE).  And there is the redgate tool SQL Search.  But I'm not sure how to go about looking for columns that have say a value of 'PATID' and returning all tables that match.  Does anyone know?

Temporary tables are tables available for a current process only (and destroyed when process ends).

What are you approaches to creating temporary tables?

1. Process-private Globals storage can be used as a data global in storage definition. That way, each process can have its own objects for the class with ppg storage.  Here's how. Here's how 2.
2. InterSystems TSQL supports #tablename temporary tables. A #tablename temporary table is visible to the current procedure of the current process. It is also visible to any procedure called from the current procedure.

Greetings Developer Community!

Hi All,

I need to build a search using a lot of filters, what's the best way to implement my sql requests.

1 sql request per property, or only one "big" sql request ?

what's the disadvantage of using lot of indexes ?    Thank you

Where can i get the latest odbc providers from SQL Server 2012/2016?

I see some posts on line to  an ftp site out there but I am unsuccessful at getting access to it.  I have a version loaded on my server but get errors when querying cache'.

"[Cache ODBC][State : 22005][Native Code 22005]" 

Any help would be appreciated.

the one we have might be version  2014.01.05851  64 bit (would that make sense?)

Let's say I start with a date range of '1-5-2019' to '5-25-2019' that occurs on one row.  I'd like to ultimately have this show as 5 rows in Crystal Reports as shown below

Result

1-5-2019  1-31-2019

2-1-2019 2-28-2019

3-1-2019 3-31-2019

4-1-2019 4-30-2019

5-1-2019 5-25-2019

I found a result that worked in T-SQL, but I'm not sure how to translate it to Cache SQL.  The T-SQL code is

select dateadd(d,N.number,d.begindate) adate, data
  from data d
  join Numbers N ON number between 0 and datediff(d, begindate, enddate)

This code fetches a row for every day between the begin date and end date.

In T-SQL, I can create a recursive CTE to create a subquery or a view that will hold a whole lot of numbers.  Is there a way to do this in Cache SQL?  I'd like the numbers from 0 to 10000 if possible. 

Thanks!

Hi,

Do you have any experience in server side pagination with IRIS using Angular on the client side?
Any idea on a typical SQL request on the server side?

Thanks!

Hi,

I created a BS with a SQL Inbound Adapter.

Query = "SELECT rowid, fname ,lname,datesent 
                   FROM labs
                   WHERE datesent IS NOT  NULL"

DeleteQuery = " update labs set datesent =  Getdate() where rowid = ?"

KeyFieldName = "rowid"

i am getting the following errors.

"NOT assuming network disconnect error based on: Gateway failed: DropStatement."

"Skipping previously errored row '235'"

"Assuming network disconnect error based on: SQLState: (HY000) NativeError: [0] Message: [Microsoft][SQL Server Native Client 11.

This error is sometimes seen while viewing a listing in InterSystems IRIS Business Intelligence:
ERROR #5540: SQLCODE: -99 Message: User <USERNAME> is not privileged for the operation (4)

As the error suggests, this is due to a permission error. To figure out which permissions are missing/needed, we can take a look at the SQL query that is generated. We will use a query from SAMPLES as an example.

SELECT TOP 1000 %ID, DateOfSale, Outlet->City, %EXTERNAL(Channel) AS Channel, Product->Name AS Product, UnitsSold, AmountOfSale AS Revenue, (Discount * 100) || '%' AS Discount, Comment FROM HoleFoods.

I have a code block in a BPL.  I have the below SQL and code.  All variables have been declared and set.  When I run the SQL, if there are no values returned, I get 100 for the value of SQLCODE when I perform the FETCH, which is correct.  If values are returned, I get a -400 error when I perform the first FETCH.  I've investigated, but cannot find the reason for a -400 error.  Hoping someone out here understands this and knows what's wrong.

   &sql(DECLARE D1 CURSOR FOR SELECT A.SHIPMENTTRACKINGNO, A.SERIALNO, A.CDWACCNO, A.CDWINVOICENO, A.CDWORDERNO, A.CDWPARTNO INTO :context.

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.

HI I am using below code to retrieve the last inserted ID of the table. It works when we do not set any custom column as IDKey. If we define any column as 

IDKey below code does not return any IDKey. I know when i am defining any column as IDKey its not auto generated , but whats the best way to get the ID column value
