#Caché

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

Documentation.

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")
)

Hello everyone,

I am searching, but i cannot find a way to call a Procedure in Caché with PHP. Using .NET we have the Intersystems.Data.CacheClient.CacheCommand and we make a call in a Procedure. How i can do the same in PHP?

Hi!

I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns.

Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.

Here is my code:

We often have troubles with performance when joining tables with about 10 million rows together.

Sometimes we can't say what the cache engine is doing, it's just sucks and never finishes.

Then we have to rebuild the query and loop first on Orders and then on OrderPositions.

this is what we want:

EDITED: the join was only forgotten

ObjectScript error handling snippets

ObjectScript has at least three ways of handling errors (status codes, exceptions, SQLCODE, etc.). Most of the system code uses statuses but exceptions are easier to handle for a number of reasons. Working with legacy code you spend some time translating between the different techniques. I use these snippets a lot for reference. Hopefully they're useful to others as well.

Referencing this post:

I'm not sure how to actually interact with the result set I get from doing something like this. I want to return something like:

[{"field1":1, "field2":2}, {"field1":2, "field2":10}]

I'm finding it very difficult to get it in this format, since %Print appends a newline onto the end of the {} object it prints.

Here's the closest I've gotten:

Tortoise GIT Setup

We are currently trying to implement TortoiseGIT into Cache Studio as per the following Github project

https://github.com/intersystems-ru/cache-tort-git

Our architecture is as follows:

- A server with Ensemble installed on

- Team of several members connect to the server and perform their code build

TortoiseGIT was installed on the server, however, should the REPO location be:

- on the server itself (as a shared path)?

Today in docs I found this example using NULL:

 WRITE $LISTVALID($LB(NULL)),!

simplified

zzdump $LB(NULL)

and NULL can be case-insensitive:

zzdump $LB(null)

seems the same as just:

zzdump $LB()

But if null variable is defined then list would contain value from variable. Case sensitive in that situation.

Does anyone have any Idea what is this? Is NULL used anywhere besides as a list element?

Hello

I made for fun a bash script that creates csv files from a %GOGEN exported file.
%GOGEN, the utility for exporting globals for Cache 5.xx

First I thought it would be very simply with bash, but ...
- if I want a header in the csv file
- if you export with GOGEN more globals together not only one
- if I want a csv file for every global/indexes has the global ..

The simply bash script goes up 100 lines of code. If I will start again with this, I would use Python or Go, not bash.

Example:

For a EXPORTED.GLO file

Suppose we need to store millions of values temporarily, that means, we don't care about them if we lose them but our application use them to get realtime information. Should I use Cachetemp or whatever other DB without journaling enabled? If answer is Cachetemp, shouldn't be a problem if we decide to scale using App Server + ECP? I'm not sure what would happen with the app logic in such architecture as I guess I couldn't map and share cachetemp...

Any idea/suggestion?

Hello,

I am struggling to print out the actual property values of the Security.System class.

https://cedocs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls

I was hoping to be able to print the Authentication Enabled properties of a system from the command line using the Get or GetProperties class method. Currently, however, I am only able to get a return 1 or Invalid Oref error.
