Assume Jack & Jill are two managers. Jack has one reportee called James and Jill has none. So when we establish Parent-Child relationship, Jack & Jill will be at Level 1 and James will be at Level 2. In our project all the 3 people make sales. Hence a manager like Jack will have his group sales and his own sales.
To represent it, i have set the property "MembersWithData = NonLeafDataVisible" for parent attribute. When I browse the cube the data is represented something like this
Jack --- $100
Jack (Direct)------$60
James ------$40
Jill ---- $200
We can clearly see that Jill doesn't have any children unlike Jack. It seems SSAS adding a member (in our case "Jack (Direct)") as its own children only when it really has some children.
What should I have to do if I want to have "Jill (Direct)" under Jill, something like following.
Jack --- $100
Jack (Direct)------$60
James ------$40
Jill ---- $200
Jill (Direct)------$200

I've tried to create extra columns to use Case expression after that, but it seems too complex.
SELECT *,

JSON_VALUE(w.AllParticipants,'$[1].ParticipantName') AS ParticipantName2,
JSON_VALUE(w.AllParticipants,'$[2].ParticipantName') AS ParticipantName3,
JSON_VALUE(w.AllParticipants,'$[3].ParticipantName') AS ParticipantName4

I'm wondering if there is an easy way to compare values and extract only unique ones.
I have tried to simplify my question with the following example:
I have a table with the following data:
Marker Name Location
1 Eric Benson Mixed
2 John Smith Rural
3 A David Rural
4 B John Mixed
And i want to insert into the table:
Name Location
Andy Jones Mixed
Ian Davies Rural
How can i continue the sequencein the Marker column to end up with:
Marker Name Location
1 Eric Benson Mixed
2 John Smith Rural
3 A David Rural
4 B John Mixed
5 Andy Jones Mixed
6 Ian Davies Rural
If you make this with a Stored Procedure you can ask the max of the Marker before to insert.
(That only works if the Marker Column is not identity)
Like This:
declare #max_marker int
set #max_marker=isnull((select max(marker) from table),0)
--Insert comes here
Insert into table (Marker,Name,Location) Values(#max_marker+1,'Andy Jones','Mixed')
I have to write a query in Oracle. I have a table called 'Entity' with 2 columns 'Pref_mail_name' and 'spouse_name'.
Now i want list of all spouse_name where the last name of the spouse_name is not populated from pref_mail_name.
For example my table has following data
Pref_mail_name spouse_name
Kunio Tanaka | Lorraine
Mrs. Betty H. Williams | Chester Williams
Mr. John Baranger | Mrs. Cathy Baranger
William kane Gallio | Karen F. Gallio
Sangon Kim | Jungja
i need output as 1st and 5th row only. I did some analysis and came up with oracle built in function
SELECT PREF_MAIL_NAME, SPOUSE_NAME, UTL_MATCH.JARO_WINKLER_SIMILARITY(a, b)
similarity from entity
order by similarity;
But above query is not looking genuine.Even though spouse last name is not populated from pref_mail_name its giving a value above 80 for similarity.
The project I'm asking about is for sending an email to teachers asking what books they're using for the classes they're teaching next semester, so that the books can be ordered. I have a query that compares the course number of this upcoming semester's classes to the course numbers of historical textbook orders, pulling out only those classes that are being taught this semester. That's where I get lost.
I have a table that contains the following:
Professor
Course Number
Year
Book Title
The data looks like this:
professor year course number title
--------- ---- ------------- -------------------
smith 13 1111 Pride and Prejudice
smith 13 1111 The Fountainhead
smith 13 1222 The Alchemist
smith 12 1111 Pride and Prejudice
smith 11 1222 Infinite Jest
smith 10 1333 The Bible
smith 13 1333 The Bible
smith 12 1222 The Alchemist
smith 10 1111 Moby Dick
johnson 12 1222 The Tipping Point
johnson 11 1333 Anna Kerenina
johnson 10 1333 Everything is Illuminated
johnson 12 1222 The Savage Detectives
johnson 11 1333 In Search of Lost Time
johnson 10 1333 Great Expectations
johnson 9 1222 Proust on the Shore
Here's what I need the code to do "on paper":
Group the records by professor. Determine every unique course number in that group, and group records by course number. For each unique course number, determine the highest year associated. Then spit out every record with that professor+course number+year combination.
With the sample data, the results would be:
professor year course number title
--------- ---- ------------- -------------------
smith 13 1111 Pride and Prejudice
smith 13 1111 The Fountainhead
smith 13 1222 The Alchemist
smith 13 1333 The Bible
johnson 12 1222 The Tipping Point
johnson 11 1333 Anna Kerenina
johnson 12 1222 The Savage Detectives
johnson 11 1333 In Search of Lost Time
I'm thinking I should make a record set for each teacher, and within that, another record set for each course number. Within the course number record set, I need the system to determine what the highest year number is - maybe store that in a variable? Then pull out every associated record so that if the teacher ordered 3 books the last time they taught that class (whether it was in 2013 or 2012 and so on) all three books display. I'm not sure I'm thinking of record sets in the right way, though.
My SQL so far is basic and clearly doesn't work:
SELECT [All].Professor, [All].Course, Max([All].Year)
FROM [All]
GROUP BY [All].Professor, [All].Course;
Use your query as a subquery and INNER JOIN it back to the [ALL] table to filter the rows.
SELECT
a.Professor,
a.Year,
a.Course,
a.title
FROM
[ALL] AS a
INNER JOIN
(
SELECT [All].Professor, [All].Course, Max([All].Year) AS MaxOfYear
FROM [All]
GROUP BY [All].Professor, [All].Course
) AS sub
ON
a.Professor = sub.Professor
AND a.Course = sub.Course
AND a.Year = sub.MaxOfYear;
I'm having trouble understanding how to do a multi-table join without generating lots of duplicate fields.
Let's say that I have three tables:
family: id, name
parent: id, family, name
child: id, family, name
If I do a simple select:
select family.id, family.name from family
order by family.id;
I get a simple list:
ID Name
1 Smith
2 Jones
3 Wong
If I add an inner join:
select family.id, family.name, parent.first_name, parent.last_name
from family
inner join parent
on parent.family = family.id
order by family.id;
I get some duplicated fields:
ID Name Parent
1 Smith Howard Smith
1 Smith Janet Smith
2 Jones Phil Jones
2 Jones Harriet Jones
3 Wong Billy Wong
3 Wong Rachel Wong
And if I add another inner join:
select family.id, family.name, parent.first_name, parent.last_name
from family
inner join parent
on parent.family = family.id
inner join child
on child.family = family.id
order by family.id;
I get even more duplicated fields:
ID Name Parent Child
1 Smith Howard Smith Peter Smith
1 Smith Howard Smith Sally Smith
1 Smith Howard Smith Fred Smith
1 Smith Janet Smith Peter Smith
1 Smith Janet Smith Sally Smith
1 Smith Janet Smith Fred Smith
2 Jones Phil Jones Mark Jones
2 Jones Phil Jones Melissa Jones
2 Jones Harriet Jones Mark Jones
2 Jones Harriet Jones Melissa Jones
3 Wong Billy Wong Mary Wong
3 Wong Billy Wong Jennifer Wong
3 Wong Rachel Wong Mary Wong
3 Wong Rachel Wong Jennifer Wong
What I would prefer, because it's more human readable, is something like this:
ID Name Parent Child
1 Smith Howard Smith Peter Smith
Janet Smith Sally Smith
Fred Smith
2 Jones Phil Jones Mark Jones
Harriet Jones Melissa Jones
3 Wong Billy Wong Mary Wong
Rachel Wong Jennifer Wong
I know that one of the benefits of an inner join is to avoid presenting excess information through a Cartesian product. But it seems that I get something similar with a multi-table join. Is there a way to summarize each group as shown above or will this require post-processing with a scripting language like Python?
Thanks,

This is precisely the way the relation databases work: each row must contain all information in itself, with every single field that you request. In other words, each row needs to make sense in isolation from all other rows. If you do a single query and you need to get all three levels of information, you need to deal with eliminating duplicates yourself for the desired formatting.
Alternatively, you can run three separate queries, and then do in-memory joins in code. Although this may be desirable in certain rare situations, it is generally a wrong way of spending your development time, because RDBMS are usually much more efficient at joining relational data.
You've hit it on the head. You'll need some post processing to get the results you're looking for.
SQL query results are always simple tabular data, so to get the results you're looking for would definitely not be a pretty query. You could do it, but it would involve quite a bit of query voodoo, storing things in temporary tables or using cursors, or some other funky workaround.
I'd definitely suggest using an external application to retrieve your data and format it appropriately from there.
ORMs like Entity Framework in .NET can probably do this pretty easily, but you could definitely do this with a few nested collections or dictionaries in any language.
