Hi all,

I have a non objectscript application connecting to a cache instance via ODBC and one column is a list of serial objects. The output from the query contains a lot of special characters and I'm hoping there's a better way to get this data back so I won't have to perform extensive parsing on the application side.

I've tried using the $ListToString() function, but that didn't help much, probably because the list contains complex objects rather than primitives.

Any help will be greatly appreciated!

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.

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.

In this article I will demonstrate the following :

  • Update ReferencesRange(OBX:7) against ObservationIdentifier(OBX:3.1)[TestCode] from database by using custom utility function
  • Update Abnormal Flag(OBX:8) against ObservationIdentifier(OBX:3.1)[TestCode] and ObservationValue(OBX:5)[Result] from database utility function
  • Route Message based on Abnormal Flag(OBX:8)

Below is the primary and transformed HL7 2.5 ORU_R01 message:

II try to explore the new SQL LOAD DATA feature in SQL comparing it to SQL INSERT

I'm stuck at this point: INSERT INTO <table> (columns...) VALUES (.....)
allows having not just simple column references but also ALL Standard SQL FUNCTIONS (at least)
example:

INSERT INTO Test (ShortName,DOB) VALUES (SUBSTRING(Name,1,4),TO_DATE(displayDate,'MM-DD_YYY'))

This works perfectly.
BUT the same VALUE clause applied to LOAD DATA fails in various ways:

PrimaryKey vs Idkey

Just wondering an Insight in the difference between these two indexes

IdKey / PrimaryKey
=================

Property Identifier As %Integer

Index Index1 on Identifier [Idkey]

Index Index2 on Identifier [PrimaryKey]

What's the difference?

1. If I don't have Index1 and only have Index2, then cache does still make its own id.
So how and why do I ever use the PrimaryKey. In Joins ??

What is the recommended approach to handle the following scenario: Large number of HL7 messages are serviced via Ensemble. Those messages are then transformed and routed to an Operation which calls a web service which does a number of different activities. If will do address normalization, location geo coding, MPI lookup and resolution, and insert into a SQL Server database to stage for an analytics product. Unfortunately all of this work takes time and the first thing that happens in the web service is a lock taken out on the Patien in SQL Server.

Looking for work

Hi every body

I hope it's the right place & I'm not offending any body.

I'm a veteran Mumps/Cache/Ensemble programmer . I think my only draw back is my age, although my brain is still young & bubbly.

I'm looking a long time for work without success.

I gathered a lot of knowledge & experience during those long years , developed many projects & i'm ready to do any work only to feel useful.

I'll add my resume, I hope & wish that this post will bring some change as I'm desperate to get some work.

Let's imagine you have only SQL. You need some table where you should increment value in some property when you update this line.

We have the table

CREATE TABLE "test" (
  "identifier"   VARCHAR(200) NOT NULL,
  "value"        INTEGER,
  PRIMARY KEY ("identifier")
)

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

Hi! I have a complex SQL select query which I execute via %ResultSet. It also includes a UNION. The select statement within the union should only be done when an external parameter is set, and I'm not sure of way of doing that within SQL, other than something like

SELECT FOO FROM BAR

WHERE (some conditions)

UNION

SELECT FOO2 FROM BAR2

WHERE :doUnion = 1 AND (some conditions)

...this works, but I don't think it's particularly optimal as I believe it will still execute the second SELECT regardless of :doUnion. It's also sort of hard to read...

Hi All,

I am a beginner in cache. I need to extract data from multiple tables (4-5) tables based on an SQL query . The data is more than 9 lakhs of records (i checked using count). The total number columns is 16.

When I am running this SQL query through management portal, I am getting time out exception. Could you please suggest how I can retrieve those records. Which way will be good (Dynamic query using %SQL.Statement or Embedded SQL (not known to me) or Writing to a global will help or not).

I have a class which defines a property as array of %String. Is it possible to index values of this property and use this property in SQL?

I have tried 'Index idx On prop(ELEMENTS)' and then a select from the generated collection table, but this is still orders of magnitude slower than queries to the containing class.

We have a new requirement being push down by our Data Security to no longer use Local SQL Accounts to access our Databases. So they asked me to create a Service Account that is on the Domain for our connections to each database.

I tried just changing my JDBC connection to using this Service Account and Password but I am not having any luck trying to connect to the database.

" Connection failed.
Login failed for user 'osumc\CPD.Intr.Service'. ClientConnectionId:ade97239-c1c8-4ed1-8230-d274edb2e731 "

Hi Community!

There are two general ways to execute arbitrary SQL in serverside ObjectScript code: EmbeddedSQL and ObjectScript SQL a.k.a. Dynamic SQL.

E.g. if we want to get the value of the property of instance with a certain ID using SQL we can do:

&sql(SELECT Name INTO :name FROM Sample.Person WHERE ID=1)

write name

Same result with %SQL.Statement:

set rs=##class(%SQL.Statement).%ExecDirect(,"SELECT Name as name FROM Sample.Person where ID=1")
  do rs.%Next()
  write rs.name

Credentials - Domain Account

Hi,

I've a Service utilising the Adapter EnsLib.SQL.InboundAdapter, which uses a Credentials item set with the details of a local SQL account. This currently works, however, we're looking to use the credentials of an AD domain account.

The domain account is a member of an AD security group, which has the required permissions on the source SQL database. I've checked that access is possible with this account via SQL studio.

Hi,

My doubt is about the SQL Query in Caché:

I don't want to take all results from the table and orgainze them manually, for example: I have a table with 50 records, but I only want to select 10 records, being from tenth until the twentieth and this without knowing their IDs.

So, how can I do this, without losing performance, there is any way?

SQL Developer Experience survey

Hi all,

In order to prioritize functional requirements for evolving our SQL developer experience, we have prepared a short survey to better understand how you’re currently using and, in an ideal world, would like most to interact with our SQL platform.
