Documentation explains both functions well and with examples, so I encourage you to look into them. Especially first two examples for %ALL function

ALLMEMBERS -- function that returns a set of all members of the given level or hierarchy http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=D2RMDX_AllMembers

%ALL -- function that enables you to use a member while ignoring any ROW and COLUMN context that uses the hierarchy to which this member belongs. http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=D2RMDX_percentAll

As to your question about calculating percentage of the top level, here is sample that for each product calculates revenue percentage of total from all products (2nd column) and from category for this product (3rd column).

Sample pivot

RevenuePctOfAllProducts and RevenuePctOfParent are calculated measures that defined as follows:

RevenuePctOfAllProducts:

Measures.[Amount Sold] / SUM(Product.[All Product].%ALL, Measures.[Amount Sold])

RevenuePctOfParent:

Measures.[Amount Sold] / SUM(Product.CurrentMember.Parent, Measures.[Amount Sold])

So the full query looks like:

WITH
MEMBER [MEASURES].[RevenuePctOfAllProducts] AS 
    'Measures.[Amount Sold] / SUM(Product.[All Product].%ALL, Measures.[Amount Sold])' 
MEMBER [MEASURES].[RevenuePctOfParent] AS 
    'Measures.[Amount Sold] / SUM(Product.CurrentMember.Parent, Measures.[Amount Sold])'
SELECT NON EMPTY {[Measures].[Amount Sold],
                  [MEASURES].[REVENUEPCTOFALLPRODUCTS],
                  [MEASURES].[REVENUEPCTOFPARENT]} ON 0,
    NON EMPTY HEAD(NONEMPTYCROSSJOIN([Product].[P1].[Product Category].Members,[Product].[P1].[Product Name].Members),2000) ON 1 
FROM [HOLEFOODS]

As far as I understand such usage of GROUP BY and select columns is not standard in SQL world.

That is -- if we GROUP BY some fields, then in SELECT list we can have either fields we group by or other fields as arguments of aggregate functions.

We can write

SELECT home_state, max(age)
FROM sample.person
GROUP BY home_state

But we cannot write

SELECT home_state, max(age), name
FROM sample.person
GROUP BY home_state

It is not clear -- what name out of all rows that have the same home_state do we want.

Consider following data in Sample.Person:

Age Name Home_State
10  John MA
10  Jim  MA

What name will following query return John or Jim?

SELECT Age,Name
FROM Sample.Person
GROUP BY Home_State
HAVING Age = MIN(Age)

I prefer following variant of the query with join:

SELECT Age,Name,home_state
FROM Sample.Person p1
WHERE age =  (
    SELECT min(age)
    FROM Sample.Person p2
    WHERE p1.home_state = p2.home_state)

That returns both rows from the sample data above.

I wonder if this extra line is caused by the line break between </script> and the xml header.

Can you try to move

<?xml version="1.0" encoding="UTF-8" ?>

Before <script> ?

Hi Cheng Cheng.

%DeepSee.ResultSet has property %UseCache to make query not to use cache. You can set it if you run using %DeepSee.ResultSet directly.

As far as I know this is not configurable from Analyzer or User Portal. And it cannot be set system- wide or for particular cube.

Regards, Alexander.

Attila, can you please elaborate on why it is potentially dangerous to refer to data outside of current record unless Calculated is specified?

I personally use Calculated only when property value might change during oref lifetime. If property value is not changed once object is in process memory, then there is no need for Calculated, as I understand -- Transient is enough.

I usually create new empty DB, then ^GBLOCKCOPY globals from old DB. And then replace old DB with the new one.

Yes, Illegal CSP Request usually means that access to this particular class is prohibited.

If your web application named '/csp/healthshare/mhclib/' then you need to enable classes as follows:

set ^SYS("Security","CSP","AllowClass","/csp/healthshare/mhclib/","%SOAP.WebServiceInfo")=1
set ^SYS("Security","CSP","AllowClass","/csp/healthshare/mhclib/","%SOAP.WebServiceInvoke")=1

Notice that calling SOAP Service via test webpage (%SOAP.WebServiceInvoke.cls) is independent from calling web service via SOAP protocol. For that you should check option "Inbound Web Services" in Web application settings.

%SOAP.WebServiceInfo and %SOAP.WebServiceInvoke are just pages to test web services via Browser.

SOAP protocol itself does not use these pages.

Message "An error occurred with the CSP application and has been logged to system error log (^ERRORS)"

means that you can check error in Management Portal -> System Operation -> System Logs -> Application Error Log -> [Namespace]

Or for debugging purposes set error page for web application to %CSP.Error.cls http://docs.intersystems.com/cache20161/csp/docbook/DocBook.UI.Page.cls?KEY=GCNV_R2015_2#GCNV_C140105

and see errors on the page itself

You can create one post that is just an index and reference this post in each new material.

Then just update this index post once after each new posting

Hi Randy.

FILTER option in SETTINGS references "Allowed Default Values for Filters" section of doc http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=D2IMP_ch_settings#D2IMP_filter_default_values

You can specify set of members as follows:

"{&[keyval1],&[keyval2],&[keyval3]}"

Then you need to URL encode this value: http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=D2IMP_ch_dashboards#D2IMP_dashboard_url_encoding

Particularly by replacing & with %26 and , with %2C

For example, if I want to pass to "Basic Dashboard Demo" several values for Home Zip Code filter I need to create following string:

&SETTINGS=FILTER:[HomeD].[H1].[ZIP].{&[32006],&[32007]}

And then URL encode it to

&SETTINGS=FILTER:[HomeD].[H1].[ZIP].{%26[32006]%2C%26[32007]}

Hi Blaise.

Does following query looks like what you need?

With Member Measures.[RunningTotal] As 
     'AGGREGATE(%TIMERANGE(DateOfSale.[Actual].[MonthSold].&[201101],DateOfSale.CurrentMember),
                MEASURES.[Amount Sold])',FORMAT_STRING='$#,#.#' 
SELECT {Measures.[Amount Sold],Measures.[RunningTotal]} ON 0,  
        [DateOfSale].[Actual].YearSold.&[2016].CHILDREN ON 1 
FROM HOLEFOODS

It prints two columns -- Revenue in current month and Total revenue from 2011-01 up to current month. Rows are months of 2016 year.

Yes, seeing comments/answers in compact mode is good feature.

Maybe one column is enough -- with two numbers separated by slash -- "5/10" -- 5 answers and 10 comments and sort by sum of these numbers. But that is just an idea.

As far as I know office365.com requires STARTTLS that is supported as UseSTARTTLS property of %Net.SMTP starting with Cache 2010.2

Thank you Jose-Tomas.

As I understand (please see last three paragraphs of "Cyrillic4, Cyrillic3, and umlauts" section), Spanish language has some specific collation rules and satisfying these rules require more general (and complex) algorithm than sorting two strings based on individual character codes. That is why Spanish collations are slower then Caché Standard. https://en.wikipedia.org/wiki/Alphabetical_order#Language-specific_conventions

The more processing you application does besides looping with $Order/$Query and inserting data into global the less impact has collation performance. Running ^%SYS.MONLBL with globals/locals with different collation settings should give you more accurate performance data.

As far as I know it is not possible to switch it on.

You might find function DESCENDANTS (http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=D2RMDX_Descendants) helpful.

For time dimension, all members of the level are generated and available to queries that show empty. This means

SELECT DESCENDANTS([DateOfSale].[YearSold].&[2015],DateOfSale.DaySold) ON 1 FROM HoleFoods

will show all days from 2015 on rows, whether there are facts recorded for those days or not.

SQL Adapter does some metadata caching.

See, for example, doc for method EnsLib.SQL.Common:ExecuteProcedure http://docs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls?PAGE=CLASS&LIBRARY=ENSLIB&CLASSNAME=EnsLib.SQL.Common#METHOD_ExecuteProcedure

"Appending a '#' to the pIO argument (or passing only '#') prevents the adapter from using cached DescribeColumns() results for the procedure call output, forcing a fresh call to ODBC DescribeColumns() every time the stored procedure is invoked. This can be necessary if the procedure is capable of returning different sequences of result types from consecutive invocations"

I'm not sure if this is what happened in this case, though.

By default %ToJSON method prints empty properties.

If you pass pFormat without "e" flags (that is passed by default), then empty properties are skipped:

USER>set p = ##class(%ZEN.proxyObject).%New()
 
USER>set p.a = 1
 
USER>set p.b = 2
 
USER>do p.%ToJSON()
{
        "a":1,
        "b":2
}
USER>set p.b = ""
 
USER>do p.%ToJSON()
{
        "a":1,
        "b":""
}
USER>do p.%ToJSON(,"alotw")
{
        "a":1
}

I encourage you to use Caché 2016.1 with native JSON support. Don't start with %ZEN.proxyObject. See great article by Stefan Wittman about JSON support in 2016.1: https://community.intersystems.com/post/introducing-new-json-capabilities-cach%C3%A9-20161
