I have been working on a project in our Dev environment which resulted in processing a few (million) HL7 messages, and I thought it would be a good idea to purge the namespace in a controlled way. My concern was when it hit the day where the scheduled task would purge 'the day of a million messages', it would fill the Journal Drive quite dramatically and would happen overnight resulting in triggering a response from the poor person on out of hours support.

My idea of a controlled way was to:

I ran the below query in three different modes. Coordinated Universal Time is 5 hours ahead of Eastern Time so there is difference in value from column 1 and column 2 in ODBC, Display mode, but not in Logical Mode. By default the query executes in ODBC mode when we query the data from outside world(via ODBC connection).

I don't know why query 2 and query 3 outputs different from query 1.

Query 1. Ran in Logical mode, DATEPART() took in memory stored timestamp data(stored in UTC)

I have an Ensemble installation and just build my first RestService (using %CSP.Rest that forwards them to my Business Service). This works nice and fine when I use postman to make REST calls over http (port 57772). However when I attempt to make a request using https over port 443 I receive the following error:

Hello, this is going to be a stupid question, yea I know, there are no stupid questions.

Say, I have an Object Property, Name or Count or Title, or whatever.

How can I get a list, or find out all the different ways it can be expressed?

Example:

-Property Name As %Name;

-Property Name As %String="me"

-Property Name As %String [ Required];

But what other parameters, keywords, restrictions, lists, etc. that I can apply to this Property?

We have an web application accessed using https, that uses CSP technology with frames.

The initial 'login' is via a single CSP page, which then redirects to another CSP page which creates the frames (4 in all) and loads a CSP page in each of those. For the most part the frames load without error, but sometimes when logging in and sometimes while using the system ' 5916 Illegal CSP Request ' errors occur.

I say 'login' in inverted commas as a Cache login is not performed just an application login, I don't know if that's relevant so thought I'd mention it.

how to release row lock?

I have restored one database from backup, but when I query from some of tables, prompt error :

this error remain after restart Caché service

I can skip this error with %nolock in select query.

My question is:

1. why there were locks after restart service?

2. Can I release/rollback these locks by sql so I can query without %nolock?

Force inner select to be executed

I have a query that I am attempting to run, but inner query is being rolled up into the overall query - per the optimizer (and jobexam observation). While I know that if the inner query runs first, I will eliminate a number of records (making the result set smaller, and return quicker).

Just an example of what I am attempting to do:

Hello All,

I am looking to send out an email based on a patient's discharge where PID13-4 contains their email. We are currently using something similar with an Email.OutboundAdapter. However, in our current scenario we have a hard coded email in place as the recipient (as this is for order notification to a pager). In the scenario in question, I would need PID13-4 to populate as the recipient of the email. Does anyone have an example of something similar, or a suggestion on where to start?

Thanks!

Thanks a lot, that we finally got the new version of Atelier, where most of the errors were fixed.

But I've found some have not fixed yet.

    set destination = $listget(waypoints,*)
    set $list(waypoints,*,*)=""

In this code, Atelier does know about asterisk as a second argument to $listget function.
And in this case, even shows next lines as an error.

I'm trying to write a method to Export SQL Privileges from an instance by namespace, user, or roles. I've found two classes that might work:

  • ##class(Security.Users).Export
  • ##class(Security.SQLPrivileges).Export

One (Security.Users) exports an XML file and the other (Security.SQLPrivileges) exports an SQL file.
