SQL

Hi, I want to INSERT a customerID and customerName to a table if the customerID does not exist. Or UPDATE if they've changed their name.
I've reviewed the documentation (https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=RS...) and have confused myself with the INSERT OR UPDATE statement. Rather than using two individual statements , is there a way to get it in one?

What I have at the moment doesn't do anything. In fact it errors.

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 !   

In most cases, a global used by default storage has just 1 subscript level that represents the IDKEY.
For an index-globals we may see 2 or more subscript levels.
Arrays, or parent-child relationships or persistent classes extending a base data class
are examples where we see more levels. Though all these globals are quite uniform.

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

Is there any way to change the sql Shell interface to output a <TAB> between the fields instead of outputting one or more spaces between columns

I needed to run an sql ( that took a while to run) and then  cut and paste the generated output into excel, trouble was the paste into excel was not very good for columns when there's spaces used between the columns

The Art of Mapping Globals to Classes (4 of 3)

The forth in the trilogy, anyone a Hitchhikers Guide to the Galaxy fan?

If you are looking to breathe new life into an old MUMPS application follow these steps to map your globals to classes and expose all that beautiful data to Objects and SQL.

If the above does not sound familiar to you please start at the beginning with the following:

What is the sql command to describe table in cache db.

Hi,

I get this error [Cache ODBC][State : HYC00][Native Code 469] and zero rows returned with the following query.

SELECT "Timestamp","Skillset"  FROM "dbo"."iSkillsetStat" 
WHERE (Timestamp >= '2020-06-29 00:00:00' 
AND Timestamp < '2020-06-30 00:00:00')

I'm using Qlik Attunity Replicate to extract data, the query was formatted  by the tool. The query will return data in excel and SSIS, but not using Replicate.

So far I've tried using two ODBC drivers

I got a resultset, and some columns might be a JSON_OBJECT. Is there a way (based on metadata) to determine that the column was formed from JSON_OBJECT function?

set rs = ##class(%SQL.Statement).%ExecDirect(,"SELECT 1 colA, JSON_OBJECT('id':1) col2")
do rs.%Display()

I do not want to try parsing json.

Hi, I have a timestamp of 201906192359 with a HL7 and I need to add a minute to it to get 201906200000. Is there an easy way within Healthshare to do this?

It seems easy enough within SQL but I cannot get the SQL to work within Healthshare,  this is what I have for SQL which does the job in SQL Server.

 SELECT REPLACE(REPLACE(REPLACE(CONVERT(CHAR(16),DATEADD(mi,1,STUFF(STUFF(@test,11,0,':'),9,0,' ')),120),'-',''),' ',''),':','');

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?

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