hi,

i have two where-clauses:

a) ... WHERE company=1 and product=7

b) ... WHERE product=7 and company=1

with other words the position of the where fields are swapped.

now the question is:

bring the where clauses a) and b) the same performance(queryplan) or do i have to write it in a special order???

in my point of view, there is a parser/optimizer who cares about this, so i don't have to care about.

Ambiguous sort column error

Hello,

I have a small SQL question.

Running an example queries in our Samples Namespace:

1. select top 5 Description,Category from Cinema.Film order by Category - runs fine no issues and returns 2 columns as expected

2. select top 5 * from Cinema.Film order by Category - runs fine no issues and returns 8 columns as expected

3. select top 5 Description,Category,* from Cinema.Film order by ID - runs fine no issues, and returns 10 columns, with my first 2 repeated

4. When I try to combine the first 2 queries:

The Management Portal allows you to Export one or more globals to a file that you can then Import into that or another namespace. However, the Management Portal can only be used to export entire globals. For exporting selected nodes or subtrees within a global, a different utility is necessary. This utility is the Export() classmethod in the %Library.Global class, which can export an entire global but also has the ability to export selected nodes or subtrees.

Currently we are using Health Share 2015.2.2, and looking to upgrade to the latest version in the next month.

From what I understand we have to upgrade to 2017 or 2018 prior to going to 2019.1 since 2019.1 is on the IRIS platform.

In trying to outline my steps in the upgrade process I came up with a question.

  • Can a Full System Backup from 2015.2.2 be restored into 2019.1?
  • Do I have to restore the 2015.2.2 back up into 2017 or 2018, then do the 2019.1 conversion?

Has anyone had experience with this? or should I open a ticket with WRC?

Hi all,

We just encountered an instance of a result set RS and while looping through the results, RS is getting overwritten when method 1 calls out to method 2 (in the same class). Method 2 creates it own result set also named RS.

This code is several years old and never had this problem. When I changed the name of the result set variable in method 1 the problem cleared up.

I though that variables were automatically 'newed' in classmethods. ???

Hi, I have used CSP to exec SQL selects from any own NAMESPACE. But in our servers we have many SQL GATEWAY CONNECTIONS.

I'd like to create a CSP page that could use these gateway to exec SQL using these gateway connections, only Administrators will use that page to launch many select at many dsn. I'm not sure if we must deploy that CSP on %SYS namespace and how to use DSN(SQL Gateway connections) that are defined on server.

Anoyone has made that?

For example:

DSN CLIENT ONE

CSP Webpage:

Hello Cache Developers! The purpose for this post is to outline a coding challenge that I have encountered when trying to use shortcuts (i.e. CTRL+G) within a ZEN application. Allow me to provide a summarized background:

Our application has a ZEN page (call it the PPL page) with a tablepane that displays a list of records. This page also has an iFrame (#1)

Hello everyone,

We have a process that is listening to an FTP service to collect some CSV files and process them. The process works correctly and when it ends it clears the directory waiting for it to enter some other file.

We have been receiving the following error message for a long time:

Hello, has anyone tried to use Caché as a reverse proxy ?

We are trying to embed a dashboard server (Plotly Dash in this case, but it could be anything which runs on its application server) inside our application which is written in Caché.
The dashboard/report server runs locally (for example, or inside a LAN) on port 8080, and has no authentication features, so we have to implement them on a different layer, and we'd like to use Caché for it.

Hi, Is there a way to count the number of segments in a HL7 Mesage? I tried the examples from the other answers but nothing works for me.

I am writing a function to get the last OBX segment field value 5. Below is a sample screenshot of what I want.

The number of obx segments can change, so I want to count the last obx segment and then get the field 5 value.

Would appreciate some guidance on this.

The DeclarativeCOS project is a heartfelt cry about programming in the COS language.

The purpose of the project is to draw attention of the public to improving the inner core of COS.

The idea of the project is the support of a laconic syntax for cycles and collections.

So what is this laconic something that I have come up with? Welcome to the examples below!

Examples

The key concept underlying the project is the declarative approach to writing code. You need to specify WHAT should be used and HOW.

Hi folks,

My fist post here and a tricky question right away!

I have a remote MySQL database table ("SomeData"; not under my control), and a Caché-class (remote.SomeDataAccess) linked to it via ODBC using the link table wizard.

The remote table has a field "id" which is the primary key and an autoincrement bigint value. This has been considered in the setup and the generated class has an

ToolBox-4-Iris

Hello everyone,
After some work with IRIS we want to share our ToolBox-4-Iris with you.

What is this about?

The ToolBox-4-Iris is an API for IRIS with a collection of handy and useful tools - features that are not available in IRIS, but greatly simplify application development. To save time and effort on the "typical tools" that every developer needs. This includes additional classes, individual methods or even more efficient macros, which are described in the respective packages.

I have a repository that I want to have in my /home/centos7/ directory, but it appears that Cache cannot access files there. Is that really the case?

It seems like this is the case because in System Management Portal, when I try to up a new database in /home/centos7/, there aren't any directories listed, even if I add a custom one. Is Cache blocked out from this directory, and are there any others that Cache doesn't have the permission to access?

Hi

I was wondering whether anyone can help I would like to know what is the underlying method that is used for exporting lookup tables from within studio. I would like to do this programmatically. The export function provided with Ens.Util.LookupTable is not compatible with studio.

Thank you.

Kind Regards,

Salma
