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

version cache for windows, 2017.2.1 build 801_3 - windows 10

I had this system set up for 3+ years now, and background tasks such as converting emails, have always worked, suddenly it's stopped working and I've tracked it down to any network references.

reading the emails, I look for any attachment files, and save them to a network drive before processing them within a class method,

I've been testing it by sending exactly the same email repeatedly and checking the saving of the attached file in both the background and in the terminal.

Hello,

I need to create a util function that loops thru every character in the data, execute a $ASCII() against it. If it falls outside the realm of extended ASCII we toss it.

the function should receive a string, execute a for...loop across it's length and use $ASCII to evaluate the character. Also the function should return an output argument that indicates if the string is UTF8 valid or not.

could anyone help me with this?

Hello to all,

I'm trying to post some form data from a form I made in React to the backend of cache fetching a REST-service.
Receiving and processing a JSON-object is no problem but how can I handle Form Data?

The frontend is sending the form as form data and also includes one or more files.

What is the easiest way to process this data in my REST.Broker- class?

Best regards,

Simon

Hi,

So I am a front end developer working with REST API with Cache database on the BE. The BE guys are currently using Cache through a Windows virtual machine and they claim it is not possible to have a development server to work with. All the work they are doing is directly on the production server and changes are immediate and I think this is a bad idea going forward and we most definitely need a development server that has access to the same code base and different version (through git) to be able to do development. We also do all the testing on this production server with test accounts, but we cannot do automated testing with this setup.

Hi everyone.

I wonder, whether is it possible to get description of emoji in COS.

For example, I have data with emojis like 🙏 in database, that should be delivered to transaction system via service. But service doesn't support emojis, so I want to convert emoji to its unicode description like "Person with Folded Hands". Is it possible? I'll be grateful for help

The boss (reasonable intelligent ;-) wants to connect to the cache database through Excel, but unless I explain what he's looking for (field names DB names etc) then I can see him continually coming back for "what's the link here and how do I get the delivery company name etc etc"

is there a SAFE way I can give him access to our database using an intelligent visual user interface.

I had thought about the SQL Query Builder within the management portal, but the thought of giving him access to all of the other functionality of the management portal.

I'm looking for a SQL function equivalent for SQL server STRING_SPLIT. I have records like this:

join_to_tx_history (key), ss_note_multi_dict_1_value (varchar)

and I like the field ss_note_multi_dict_1_value split to rows for each comma delimited value. So I can get this:

I am running csession on AIX. I have been using the command "csession cache -U%SYS". In the session the namespace shows as "%SYS>" as expected. I was simply doing queries to the best of my knowledge. At some point csession starting failing to reference the namespace instead showing /cachesys/mgr which is the main dir for the cache instance. I am not aware of doing anything that would cause this but more importantly, how do I correct it? I

I am executing the command:

set fileComp = ##Class(SYS.Database).FileCompact(obj.Directory, freeSpace, .actualFree)

where obj.Directory contains the location of the current database

This executes correctly. However, the resultant OREF object does not contain any displayable properties but rather is of the value:

"0 "_$lb($lb(380,,,,,,,,,$lb(,"%SYS",$lb("e^zFileCompact+38^SYS.Database.1^1","e^^^0"))))/* ERROR #380: Completed but skipped some blocks, details recorded in the console log. */

I am relatively new to Intersystems cache database management. As I understand it, a database is set with a maximum size or unlimited and the size of each space allocation for the database is defined. My understanding is that the cache database will then manage the allotment of space to the database as the current space allocation is consumed. Though I do not know why one would want to do this, I have been told that the space allocation to a database can be set to be handled manually. This is something, if true, I was not aware of.

I have a PDF ZEN report module that I'm using XslFoXslt to highlight the table cell.

What I need is for a particular value to add a background image to the <item> that is calling the XSLFoXslt

The code I have is the following but all that happens is the color.

I'm new to cache, come from an oracle and sql server background. In oracle and sql server I could write basically a stored procedure like script and pass it in as text to the command to execute.

Example:

Below would be the _sqltext

DECLARE @Id INT;

select id into @Id from something;

if @Id = 9

BEGIN

do something

END

The _sqltext would work in sql server, what would be the equivalent for cache for it work?

I get a generic error when I try it with cache

Hi all

I have a Zen page which displays the contents of a table. One of the columns is a file path to a file on a local disk.

Is it possible, on a Zen page, to allow that file that described by the file path to be downloaded when a hyperlink is clicked on?

Cheers

Hello! I am currently creating a class for a small error trap. I have it working and all is good but I really want to change the order of the fields in the SQL return from Alphabetical to something else.

The current Order is ID, ActionType, ErrorCount, ErrorDetails, Model, ResultCode, ResultMessage, Stock and Yard

I would really like for the field order to be ID, Yard, Stock, Model, etc.

Example of current order,

Is this possible?

Thanks in advance!!
