Regarding Max function in MDX - sql

I have a fact table with structure: (objectid, fromLoc, toLoc, duration).
I need the equivalent MDX for the following SQL:
select fromLoc, toLoc, max(duration) from fact group by fromLoc, toLoc;
I tried with the following MDX but it's showing wrong results. It's showing sum(duration) instead of showing max value for each grouping:
WITH
MEMBER [Measures].[MaxValue] AS
max([Measures].[Duration])
select FromLoc.members on axis(1),
toLoc.members on axis(0)
from [cube1]
where [Measures].[MaxValue]
Please help me by providing the correct MDX which can answer the queries like the above SQL.

You have have to use the max function like this:
max(the set of your objectids, [Measures].[Duration])

Select and manipulate SQL data, DISTINCT and SUM?

Im trying to make a small report for myself to see how my much time I get inputed in my system every day.
The goal is to have my SQL to sum up the name, Total time worked and Total NG product found for one specific day.
In this order:
1.) Sort out my data for a specific 'date'. I.E 2016-06-03
2.) Present a DISTINCT value for 'operators'
3.) SUM() all time registered at this 'date' and by this 'operator' under 'total_working_time_h'
4.) SUM() all no_of_defects registered at this 'date' and by this 'operator' under 'no_of_defects'
date, operator, total_working_time_h, no_of_defects
Currently I get the data I want by using the Query below. But now I need both the DISTINCT value of the operator and the SUM of the information. Can I use sub-queries for this or should it be done by a loop? Any other hints where I can learn more about how to solve this?
If i run the DISTINCT function I don't get the opportunity to sum my data the way I try.
SELECT date, operator, total_working_time_h, no_of_defects FROM {$table_work_hours} WHERE date = '2016-06-03' "
Without knowing the table structure or contents, the following query is only a good guess. The bits to notice and work with are sum() and GROUP BY. Actually syntax will vary a bit depending on what RDBMS you are using.
SELECT
date
,operator
,SUM(total_working_time_h) AS total_working_time_h
,SUM(no_of_defects) AS no_of_defects
FROM {$table_work_hours}
WHERE date = '2016-06-03'
GROUP BY
date
,operator
(Take out the WHERE clause or replace it with a range of dates to get results per operator per date.)
I'm not sure why you are trying to do DISTINCT. You want to know the data, no of hours, etc for a specific date.
do this....
Select Date, Operator, 'SumWorkHrs'=sum(total_working_time_h),
'SumDefects'=sum(no_ofDefects) from {$table_work_hours}
Where date='2016-06-03'
Try this:
SELECT SUM(total_working_time) as total_working_time,
SUM(no_of_defects) as no_of_defects ,
DISTINCT(operator) AS operator FROM {$table_work_hours} WHERE
date = '2016-06-03'

Need Alternative to SQL AVG() for Obvient BI tool

I am reading 2 fields from 1 table.
StartKey and Mins
Image below shows my current output result on left and what I need on right.
Here is my Query
Select
StartKey,
Duration as Mins
From TableA
Where Flag = 0
Order by StartKey
I know I can use avg(duration), but if I use that, Obvient, the software I am using to write and display the query, won't let me take the average of column Mins Avg itself.
This error I get after I manually insterted average code of column in CS file and then I try to edit column properties.
First, let me make sure I understand your problem.
You are using the SQL from your post while building something in Obvient which appears to be a Business Intelligence platform. The problem you are having is that you are unable to perform an average function in Obvient on the column of averages in your SQL query.
If that is correct, you should use your SQL query to create a view in the database which should appear to Obvient as a table and may allow you to perform the averaging function. I can't say for certain that this will solve your issue having never used Obvient, but give that a try and let us know how that works for you.
Seems like I'm missing something, but to get your desired results, this should work:
Select
StartKey,
AVG(Duration) as Mins
From TableA
Where Flag = 0
Group By StartKey
Order by StartKey
And the SQL Fiddle.
If your goal is to get the AVG(Mins) from the above query, you could use a subquery to return that:
Select AVG(Mins)
FROM (
SELECT
StartKey,
AVG(Duration) as Mins
From TableA
Group By StartKey
) t
Here is the Fiddle:
Good luck.

Average of sums in MDX query

How can I compute average of sums in MDX? I want to compute sum of spending for each person and then compute an average of it. I have the following query so far, but I believe it gives me wrong result:
WITH MEMBER [Measures].[Average] AS
AVG(Measures.cost)
SELECT [Measures].[Average] ON COLUMNS
FROM
( SELECT Measures.cost ON COLUMNS,
{Person.[Last name].MEMBERS}*
{Person.[First name].MEMBERS} ON ROWS
FROM Cube )
Any help would be greatly appreciated.
You just need to put in the first argument of Avg the set of your persons.
WITH MEMBER [Measures].[Average] AS
AVG(Person.[Last name].MEMBERS * Person.[First name].MEMBERS, Measures.cost)
SELECT [Measures].[Average] ON COLUMNS
FROM Cube
Try to create a calculated measure for this function like this
IIF (([Measures.cost] > 0), AVG(Person.Members,Measures.cost),null)
Then use this calculated measure in your MDX query
SELECT Person, 'calculated.measure'
FROM Cube
This is only a sample code to illustrate the function.

How do I Sum the values of a Count Distinct Aggregate of Contained Groups

I've got a bit of a problem with a grouping. At the moment I have a grouping that does a CountDistinct(Fields!AccountName.Value). This grouping is on a Financial Time Period.
I need to be able to do a Sum on the values brought forward by this CountDistinct at the end of this report, but I can't put an aggregate function within an aggregate function.
Don't suppose you guys have any idea's / help?
Thanks.
You can do a select and aggregate your set of aggregates. Something like:
SELECT sum(total)
FROM (Select count(Fields!AccountName.Value) as total, name FROM x group by name) totals

Sql Server : Column wise total SQl Query

Is it possible to get column wise total using query?
in my grid there are 20 columns. i have to display each columns total value in its footer. now im using TemplateField field and javascript function to get the total value.if it is possible to get it from sql query i can reduce the code
Try something like:
SELECT *, SUM(SalesAmount) OVER() as TotalSales
FROM YourTable
But if you only need the sum and nothing else, just do:
SELECT SUM(SalesAmount) as TotalSales
FROM YourTable
And in future, please try to give more information in your question.
Rob
To sum columns, it's best to use whatever client you're dealing with (Reporting Services, Datagrid, whatever), and just tell that to display a totals row.
If you were to do it within the same query, then you'd end up with rows that meant something different, and displaying it becomes quite awkward.
You CAN do it in the query, but you probably shouldn't.
Rob
I think you are looking for SUM function
Eg:
SELECT SUM(salary) as "Total Salary"
FROM employees
select MAX([p-1]) p1,MAX([p-2]) p2 from #temp
