Yes, it's a pain, but search within tag maybe worth it?

BTW you shouldn't scroll through the list - just start typing in tag field, it will find the valid tag for you.

Hi, Greg!

You can search within not Community but within a Tag.

For example let's search your post with the word "way".

There are a lot of results and it's a trick to find your post.

But you can dropdown Tag menu in the search result and filter results to Tag. F.e. your post has 'online-learning' tag.

Let's do it and see search results then:

You can search within several tags simultaneously.

Hope that helps.

P.S. 'Online learning' is the not very fit tag for this post. Please consider to change it to 'Developer Community' tag.

Hi, Kyle! 

Thank you, great stuff!

The guys in Russian forum says there is a bug in the line:

Property Data as %String (MAXLEN=100, MINLEN=200);

How can MINLEN be higher MAXLEN?

Hi Greg!

We do not support this type of posts anymore.

Code packages should be placed as code snippets, gist or github repos. 

See details here.

But thank you! We'll delete this artefact.

Hi Greg!

Subscriptions are not ideal at this moment and we are working to make them better.

Your suggestions are quite reasonable we'll try to introduce them to the subscription module soon.

Thanks!

Hi, Greg!

Thanks for the request! 

Yes, you are right. It's very helpful option and we have this task in our backlog.

Hi, Sergey! 

Thanks for the answer!

Yes, it's the possible reason. But the problem also appears on Unicode installations too. See my answer below.

Evgeny Shvarov · Jul 18, 2016 go to post

Hi, Randy!

It's a known issue. The problem is that DSW(DeepSeeWeb) contains some unicode symbols in UI and they come from CSP Gateway in ISO 1859-1 codepage, which is not Unicode obviously.

It happens because in your NLS scheme (I believe it is enuw) there is the default setting for non-CSP files that they should go in ISO 1859-1.

While it is not fixed in the release, it is fixable two ways:

1. Copy index.html to index.csp and try to connect to it same way you do with index.html page. Symbols should go in Unicode now.

2.  Write your current codepage setting in CSP Gateway for the files:

zw ^%SYS("CSP","DefaultFileCharset")

This setting should be "utf-8". If there is another setting, save it somewhere and change to "utf-8" 

So this should fix it:

set ^%SYS("CSP","DefaultFileCharset")="utf-8"

Hi, Mike!

There is no option to delete your own posts now. 

But you can unpublish them.

Hi, Rustam!

A lot of Caché code parts (classes, mac and int routings, DFI's etc) are stored in the database itself, not in files. They should be exported some way to be presented in files.

I see you have already the way to export classes, so I believe you can repeat similar code logic to export mac and int code part into the files in the same or another OS folder.

Sorry, Cheng Cheng!

Got the idea now: you wanted Sum function for each Product Category, and Avg function for All Products in the same pivot)

And this use case of IIF and LEVEL_NUMBER solves the task. 

Great! Thanks!

Evgeny Shvarov · Jul 12, 2016 go to post

Hi, Cheng! 

Thank you for the explanation! Great use case, btw. Now it's more clear with your initial post.

It would be great if you include Level_number in the query too to see what rows has different Level_number.

Like this:

WITH MEMBER measures.[with avg summary info] AS

                              'IIF(Product.CurrentMember.Properties("LEVEL_NUMBER") = 1,

                                 AVG(Product.[Product Category].Members, measures.[amount sold]),

                                 SUM(Product.[Product Category].Members, measures.[amount sold]))'

               MEMBER measures.[total count] AS 'SUM(Product.[Product Category].Members)'

SELECT {Product.[Product Category].Members, [Product].[All Product]} ON 1,

               {Product.CurrentMember.Properties("LEVEL_NUMBER"),measures.[with avg summary info],measures.[total count]} ON 0

FROM Holefoods

I suppose 'All Product' level should have the Sum of all Product levels. But in your example 'All product' lesser than 'Snack' for example.

HI, Cheng! 

Thanks, great example!

What is the "LEVEL_NUMBER"? Is it a kind of internal property?

Evgeny Shvarov · Jul 11, 2016 go to post

That depends on property collation. For EXACT/ TRUNCATE/SQLSTRING collation, yes "val" should exactly match the value of the property (compared part of the value), case sensitive. For SQLUPPER - no.

Should I see this collation setting in Index or in property definition? 

And what is the default setting - SQLUPPER?

Thank you, Benjamin!

It is still so much to work to make email notifications really helpful.

We'll try to fix the issues in some next releases.

Evgeny Shvarov · Jul 7, 2016 go to post

Thank you, Eduard. We plan to add Member Collaboration page with posts and comments and I think this page will be changed to the link of Member's collaboration of yourself and will go with pagination.

So it will be fixed in some next releases.

ClassMethod PropertyGetStored(id)

For datatype properties this method returns their logical value, for object properties, it returns the id. It’s a wrapped global reference to the class data global and the fastest way to retrieve the singular property value. This method is only available for stored properties.

Eduard, you say it's the fastest way to take the value. Did you measure it?

Evgeny Shvarov · Jul 6, 2016 go to post

The interesting question would be - why not traverse index global to get id instead of using SQL?

Really good question...

Another question what is the sense to check "val" for IS NULL for Unique Index?

So, "val" should exactly match the value of property, case sensitive?

Evgeny Shvarov · Jul 6, 2016 go to post

Edward, thank you for the very useful article! As addition to your article it would be great to add a demo class with direct examples of all the features.

Regarding this method:

ClassMethod IndexOpen(val, concurrency, sc As %Status)

"val" should be in Upper case I suppose?

Thank you John, some of your points here really make sense. We'll think about it.

You can be sure, that all posts in InterSystems Data Platform Blog  were reviewed by InterSystems engineers team and are promoted by InterSystems product managers.

Speaking about the high standard of technical and professional competence of engineers here in the community, I think votes, views and comments for the posts and answers can indicate the competence. I'm quite sure that there are a lot of engineers in InterSystems Developer Community (DC) who has high competence in InterSystems technology.

We have plans to introduce some signs/badges here on DC, which will indicate competence in different parts of InterSystems technology and products upon their contribution to Developer Community.
