#Caché

30

  

InterSystems Caché is a multi-model DBMS and application server. See more details here.

Documentation.

Let's say I have this simple script file try.script

write 1
write 0

I can execute it in a terminal (csession) by calling:

csession cache < try.script

And I get the following output:

%SYS>
1
%SYS>
0

However I want to use a try catch block in my script:

try {
write 1/0
catch {}
halt

But as script is executed line by line, it's interpreted like this:

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.

Been cleaning up our production 2017.1 instance of Health Connect in preparation to a move to Health Connect 2020.1 (on IRIS!)

One thing I have found I we have built up a number of old classes and other configuration files.

It would be nice to start on the new server with a clean slate.

Is there any way to identify classes that haven't been used for a long time so they can be reviewed and removed?

Kind regards,

Stephen

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

Let's say we have two serial classes, one as a property of another:

Class test.Serial Extends %SerialObject
{
Property Serial2 As test.Serial2;
}

Class test.Serial2 Extends %SerialObject
{
Property Property As %String;
}

And a persistent class, that has a property of test.Serial type:

Class test.Persistent Extends %Persistent
{

Property Datatype As %String;

Property Serial As test.Serial;

}

So it's a serial, inside a serial, inside a persistent object.

Hi,

I am getting below error in date column in a table. I am unable to query data or find distinct or to_char on this column.

Select distinct column name from table
Select column name from table
Select To_Char(column name) from table

Table has 3923509 rows.

Could someone help me how can I identify bad data in this table?

Any idea how we can avoid this error?

Hey everyone.

I have a use case where I need to write files to a handful of locations, and 2-3 subfolders in each location.

My plan was to extend EnsLib.File.PassthroughOperation and then pass that operation the file and the subfolder details, and then have an operation per destination.

Has anyone done anything similar and can highlight any pitfalls I may be about to make?

Hi everyone,

when I'm using the %JSONExport-function on Caché-Objects containing properties of type %integer, %numeric or %boolean, this properties are all automatically converted to Strings in the JSON-Output.

Is there a way to get around this type-cast?

Example:

Result with %JSONExport:

maxOrderable and maxReserveable are of type %integer, deliverable and assembly of type %boolean. All 4 properties are shown as quoted Strings.

hi-

Can someone give me an example of how to JOB a class method that requires an array of values to be passed to it by reference.

This is what I tried, but am getting compile errors because of the .params

job ##class(%SYSTEM.OBJ.FM2Class).All(.params)::5

Any thoughts on how to accomplish this, the simplest way. I would like to avoid writing all of this to some global and having to write some wrapper to pick it up and then call the class method, which I certainly could do. but is this the only way to do it?

Hi,

somehow my installation on win10 canceled during finish. "Installation of Caché finished" showed up for 20 minutes and canceled with an error I didn't saved.

Every file and service was installed but never registered as successfull installation. Now I try to reinstall it but the installer shows me everytime "Another installation is already in progress. Please finish the second installation first".

The unfinished installation is broken. I can't startup Caché from launcher. So I deleted everything in c:/intersystems

Things I already tried:

Running cache 5.0.21 64 bit on Windows server 2016 in virtual environment. Trying to understand why every single process disk read speed (simple sql data walks) caps around ~20MB/s, however 2 paralell such tasks on different data areas can reach 19MB/s each, four - 17MB/s each, that is 70MB/s total, etc. Also simple copy file to nul on that system reach ~400MB/s.

What can keep single query on idle system from reaching for example 200MB/s? Virtualization? Windows? Cache? Processors are below 1-3%

I know that 1-1 relationships are not officialy supported by intersystems cache/iris so I want to know the best way to store data with this kind of data model.

Currently I have two classes that where implemented some time ago:

Table A with a relationship type one on table B

Table B with a relationship type one on table A

To compile I have a double compile with qualifyer U.

What is the best way to implement a data model with 1-1 relationships?

Thank you

How do I compile a file through the command line?

I am generating a very basic csp page in a bash shell, it is generating fine and displays what I want to see as long as I go into studio and compile it . This defeats my purpose of having the page and I am having no luck figuring out what I am doing wrong. I think the issue has to do with the file not being included when I compile from command line.

Ver is 2017 running RHEL 7

From command line I see

TST 3f2>DO $SYSTEM.OBJ.Compile("csp.vvmaccessnewrds","h")

Now available on Open Exchange is a library of third party charts available to use within DeepSee/InterSystems IRIS BI dashboards. To start, simply download and install, select the new portlet as the widget type, then select the chart type that you desire. If you don't find the type of chart you are looking for, you can easily extend the portlet to implement your desired chart type. These new chart types can be used within existing dashboards or you can create new dashboards using them.
