Hello Everyone,

I'm want to know, what is more common for your company to use, the abbreviation syntax or the complety name of commands, and why?

Ex.

S VAR=10 / D FUNC^ROUTINE F 1:1:1000

Set VAR=10 / Do Func^Routine / For 1:1:1000

set var=10 / do func^routine / for 1:1:1000

Here in my company, we are familiar with the abbreviation syntax, because to spell is more faster.

Hi,

I am new to Cache and I am trying to convert a JSON string (msgdata) that contains a JSON payload to an object to be saved into a Driver. Entity table. I am running into 2 issues and would appreciate any help:

1) It seems that when the 1st element of a list within the payload (Choices) is an empty string, after I call %ConvertJSONToObject, the obj.%data("payload").Choices contains just 1 empty element, removing the next 3 valid values (10,20,30). The same does not happen if I change the input to [10,20,"",30], in this case it works correctly.

Similar to: "set obj = ##class(myClass).%OpenId(id)", which give the an instance of the object with given ID, is there a way to implement a function/classmethod to return the same by providing both class name and ID as a parameter, such as: getObjectInstanceByNameId(className As %String, id As %Integer), using ObjectScript code?

Multiple joins in a SQL query

HI,

I have a query like below but its syntax is not accepted by Cache.

I would like to perform a left join on two tables first and then make a inner for this result with another table.

Given the constraint that we only allow one SELECT in the query, it is possible to achieve this semantics ?

Thank for your help.

Select *
FROM ( sample . employee e
LEFT JOIN sample . company c
on c . id = e . id ) g
JOIN sample . vendor v
on v . %id = g . attr

Hi I currently have a requirement to upload microsoft documents from a client's PC to a cache database, at present the idea is to use javascript to open the file and convert it to a binary stream and then for cache csp to upload the binary stream to the database. Just wondered if anyone else had attempted this or are there better options !

Regards

Gary

I am looking to run some analysis on existing software to quickly identify global variable references. Ideally you would feed in a "starting routine" and after going through all referenced routines you would end up with a finite set of global variables. So the primary purpose is to take say 10,000 lines of code and map out the referenced global structures without relying on a programmers eye. I found the post on Object Script equivalent to Studio "Find in Files" interesting but the downside is that output is too verbose and would require parsing to extract the global structures. How would you override writing to the terminal so that you could parse the data?

Sounds odd - but I encountered it - twice now. Cache was restarted. in that period the primary journal directory was full and it was writing to the secondary journal directory. So upon start-up, it was quite obvious that it was not going to write to the primary. Cache reported this but was able to continue with the start-up but writing to the secondary. All of a sudden it doesn't recognize the 'primary' config any more and started saying 'Alternate and primary journal directories are the same'.

在Aix7.1上安装使用root用户安装cache2016.1.1.107，且在安装过程中创建cacheusr用户；更改操作系统上的cacheusr的umask后，通过数据库修改编译后的文件(如，js，csp等)在小机上查看权限不变（-rwxrw-r-- cacheusr cacheusr test.js）。

目的：通过数据库编译后的文件的other用户有读写权限。

Hey guys,

I'm working with an EnsLib.XML.X12.Document object which consists of a parent object along with multiple children.

When using the following code, my sent object is losing all references to its children. I've played with the deep parameter and nothing is working to automatically clone the objects children(group docs ref)along with itself. (Even though the documentation states that it should..)

objectClone = object.%ConstructClone()

d ..sendRequestAsync("Destination",objectClone)

Any insight would be really helpful.

Thanks!

I created a custom class for a process that does some basic manipulation to an HL7 message. I'd like to be able to write some debugging to the process event log. How would I do that?

I've tried ##class(Ens.Util.Trace).WriteTrace("system","HOSP.IHE.PDQProcess","MessageHeaderHandler","Discarding input message")

but I get a runtime error when I try that. I know this is pretty basic stuff, but any help would be appreciated.

Can anyone suggest suitable Cache ObjectScript syntax for open/use/read statements on a simple ms-dos text file.
I've tried various examples seen on the web but they appear to be implementation specific.
I used MSM MUMPS many years ago but am now retired & would like to write a few simple routines for my own amusement & mental challenge.
I am using the free Version of Cache (V 2017.1) on my Windows 10 PC. The installation file was CachePCkit_x64.exe
My apologies for this query being very basic.

I have to disect thousands upon thousands of strings like this:

96842-2-AEV.00001-63561-001958-100728760I-42

I've been able to pull out the first, second and final segments as separated by hyphens, but now I have a predicament where I need to use the second segment, the 2 shown in the example above, in a join to another table. Problem is Cache apparently doesn't like doing that. Just the same, I have to find a way.

Here's the code I'm using to pull that segment out into as separate field in the query results:

Hi-

I have created a class that extends %Persistent and %Populate and have set the various POPSPEC attributes of my properties to control how the properties are populated. However, when I compile the class and try to run the Populate() method it tells me the method isnt defined.

Here is the class definition:

Hello, I would like to know if CACHE has any limitations on uploading files.

Why am I asking this, why am I going through a problem here.

What happens is that when uploading files or images that are larger than 2.7 MB CACHE is limiting the size to 2.7 MB, any file larger than that is saved corrupted.

Already at the time of uploading the file or image, CACHE is limiting the size of the file to 2.6 MB.

Good morning everybody,

In Html sometimes we need to use entities code for don't have problems with browsers all over the world. Ex. 'á' is converted to code: 'á' / 'é' is converted to 'é'.

Cucumber / Gherkin integration

Are there any BDD testing automation implementations within Mumps/Cache Objects already in existence?

We are looking at using Cucumber for our Java regression test automation and would like to use similar feature file testing with the Cache code.


Looking to use something existing before building it.

Hello Community,

we need your help with Cache 2017.2 freezing on Linux machine.

Since we moved our primary production Cache from Windows to Linux in the begging of this year, we have experienced system freezing twice. Yesterday without any good reason Cache stopped to respond with the log shown below.

We don't often use SQL within our org, which is mostly due to the performance issue we experience due to the quantity of data we are reviewing.

Aside from the standard performance measures for non-Caché databases, are there any recommended approaches when querying large tables?

The table would have roughly 50M records, but there are not a finite amount of sub-nodes.

Hi all,

I need some advice about JSON conversions and the outputs. I am being sent a JSON response from an API call and I am struggling to produce an output that I can use from it.

I have used the %FromJSON() method call to take the JSON stream source (pData) and convert it to a Dynamic object (object) but I am a little unsure as to how I can read the dynamic object and use it to extract the values from this and set the values as a property in another class.

The current coding I have for the conversion:

Hello,

Last weekend we've updated our Caché version to

Versie:Cache for Windows (x86-64) 2018.1.1 (Build 312U)

I'm using Studio to develop. I've been using the built-in debugger and it has been working nicely. But now, since the upgrade, I'm getting this error when trying to debug any routine or class method:
