SQL

InterSystems IRIS currently limits classes to 999 properties.

But what to do if you need to store more data per object?

This article would answer this question (with the additional cameo of Community Python Gateway and how you can transfer wide datasets into Python).

The answer is very simple actually - InterSystems IRIS currently limits classes to 999 properties, but not to 999 primitives. The property in InterSystems IRIS can be an object with 999 properties and so on - the limit can be easily disregarded.

This is a coding example working on IRIS 2020.1 and on Caché 2018.1.3 
It will not be kept in sync with new versions      
It is also NOT serviced by InterSystems Support !   

Globals in Caché / Ensemble / IRIS are normally invisible over SQL access
This example shows how to overcome this limit.

This is a coding example working on Caché 2018.1.3 and IRIS 2020.2

Standard error logs in IRIS / Caché / Ensemble are written global ^ERRORS.
As this piece dates back some decades back to previous millennium its structure
is far from the typical SQL storage structures.

Is it possible execute create table from management portal?

I tried this:

CREATE TABLE SQLUser.Teste(ID INT NOT NULL,  coluna1 VARCHAR(255),  coluna2 VARCHAR(255),  coluna3 VARCHAR(255),  coluna4 VARCHAR(255)CONSTRAINT TestePK PRIMARY KEY (ID))

Error message:

Hello, I am running into a little problem.

I am trying to create a Cache Trigger on a FACS table using the SQL CREATE TRIGGER command but I am getting the message [SQLCODE: <-300>:<DDL not allowed on this table definition>].

I am not creating a persistent class but using the SQL CREATE TRIGGER command.

Please advise.

thanks.

Hi,

I'm trying to ultimately create a function that I can use with HL7 messages that calls a stored procedure held on a SQL Server.

Initially I tried extending the function class to use the sql inbound adapter and/or EnsLib.SQL.Common, but this wouldn't work from the class method for the function.

Hi,

Could someone help me in identifying all characters in a column is whole number 0 or greater

CASE WHEN '123' %MATCHES '[0-9]*' then 'VALID' else 'INVALID' end

The above statement is finding only for first character.

Thanks

Is there any way to execute many SQL commands at once as an (anonymous)block?

for example in PostgreSQL there is 

DO $$

BEGIN

--here is Inserts/Updates/Deletes

END $$

Or in Oracle  

BEGIN

END; 

Thanks for the answers!

Hi:

We added a column to a table as follows 

Property SentTime As Ens.DataType.UTC;

And the code to populate this

What is the best free/open source option to generate the database diagram (MER) to the iris or cache persistent classes?

Hello, In the DTL, is there a way to set a value for the HL7 data element in the code section? For example, set target.SetValueAt("PID:3(k1).1)") = mrn (mrn is the value returned from the SQL query) When I ran the test utility, I got this error message. ERROR ErrException: zTransform+27^testclass.TEST.1 *SetValueAt,EnsLib.HL7.Message -- logged as '-' number - @' set target.SetValueAt("PID:3(k1).1)") = mrn' I tried both target.SetValueAt("PID:3(k1).1)") and target.GetValueAt("PID:3(k1).1)"). That didn’t make a difference. The code still error out.

Since IRIS 2020.1, changed the way how embedded SQL compiled. Now it compiles upon the first execution of such queries.

Is there any way, I could switch that feature back to the previous behavior, or get some more control over it?

Hello,

I work as a contractor for the Department of Veterans Affairs. I want to read data from an Excel workbook. I searched posts here and saw Apache POI suggested. I believe Apache POI is not approved for use within VA. I also believe we should be able to run SQL query against Excel. Has anybody done such a thing or are there other ways to read data from Excel workbooks?

Thanks

Hi!

Is there a method in a persistent class that can return the current number of records/persistent objects in it?
