#Caché

57

  

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

Documentation.

I have a persistent class.

I want to store one of the properties there as a stream or a string depending on a size.

99% of values would be strings (less than $$$MaxStringLength characters) so I don't want to store everything as streams.

What do you think of this approach?

What's the best architecture to implement in this situation?

Hi all!
I need to call an API that has the following characteristics:

  • Content-Type: application / x-www-form-urlencoded
  • Authorization: (with a "Bearer" token)

In the body the information is given through the form data.

I can not find documentation on how to make this call and how to get the answer (JSON).

Could you help with an example?

Thank you

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

I have one abstract class and several subclasses. All share one data/id global.

How can I get concrete class name from id (without opening the object)?

What I have so far:

write $p($lg(^DATAGLOBAL(<id>),1),"~",*-1)

It does the job, but is there a more official way?

Rule to validate SQL syntaxis

Hi! We have received a request to create a new rule on CachéQuality to identify when a developer uses double quotes (" ") within any SQL statement.

We have been asked many times about SQL validation rules, and we would like to open a debate to allow everyone discuss what would you like to be checked on a SQL statement.

Current examples are for basic situations:

I want to upload several files using the html tag

< input multiple="multiple" name="BulkFileUpload" type="file">

. The upload.csp page in the SAMPLE namespace only shows how to extract a single file from the MimeData on the %request object. I cannot fathom how to extract multiple files from the MimeData in the %request object in cache. Can some kind soul explain to me how to do that?

REST and CSP Sessions

Hi!

We are using Rest Service with inheritance of %CSP.Rest, and we are having the following problem: when we receive 100 request from single IP adress - this creates 100 CSP sessions and takes 100 user licence for each request for few seconds. What can we do do about this? We've set this parameter:

Parameter UseSession As Integer = 1;

Thank you in advance!

In our table, we have a column cities, which has a filter which displays the cities of a state depending on the state

For simplicity let's assume we have a page

Property State As %String = "CA"

Our filter should run this query to show all cities of state ca

Indices Not Working

Forgive my lack of understanding, but I am working on a vendor created Cache database and the indexes specified in the classes for ODBC connections are not working. A few of them are created, but of the 50+ classes we have, only a handful of them are created when the class is compiled, yet no errors occur.

Example 1:

Common Testing Frameworks.

Hi,

I'm after feedback and comments on the sort of tools and approaches the wider InterSystems community uses for QA Testing applications written in Cache/Ensemble or IRIS. I am aware of the %UnitTest package, and understand how that works... but:

- Do you use an alternative or framework built around this native Unit Testing tool ?

- What is your experience with %UnitTest if you use it ?

- Is there a tool you would recommend for your UI (I know this is not specifically an InterSystems' related question)

Pretty straight forward.

I'm tempted to hard-code ISO-8859-1 inside my VSCode extension when working with CSP because this seems to be the encoding used by default, but I need to know if there's any other possible configuration. So can you share your experience when working with CSPs? Like issues with encoding, discoveries regarding it, workarounds etc.

Also, can someone tell me if it's possible to work with UTF-8 encoded CSP files using Atelier without breaking the encoding of the output file?

File System

Hello All,

I am working on Files where I have to compare contents of two files and display result.
e.g Suppose file1 contains data in Name and Roll form and file2 contains data in name and class form, so it should compare name from file1 and file2 and display those matching data(Name,Roll,class).

I have piece of idea about file system so any help would be appreciated.
Thanks in advance.

Gunwant

I am developing a viewer for Crystal Reports using the Crystal Reports for Visual Studio (CR13SP26). I have also installed the latest ODBC Drivers for Cache, but when I connect some reports to the Cache database using a connection string, I get an error that I failed to retrieve data from the database, and it reports the Database Vendor Code 30. Has anyone used Crystal Reports connecting via a connection string and received this error? If so, how did you correct it?

Thank you,

Brian Cromwell
