Creating a matrix report and linking the rows to the columns - sql-server-2008

I have this query below that works quite well generating a report like this:
Jimmy | Sword | 3
Jimmy | Axe | 0
Jimmy | Bow | 7
Alex | Sword | 1
Alex | Axe | 11
Alex | Bow | 0
Kate | Sword | 4
Kate | Axe | 6
Kate | Bow | 1
However, the powers-at-be want the PartName data across the top as columns, and then the worker and 'Total Made' count as rows for each part.
So it would look something like this:
Sword | Axe | Bow
Jimmy 3 0 7
Alex 1 11 0
Kate 4 6 1
Here is my fairly simple query that produces the first/original report:
SELECT
WorkerName, PartName,
Count(PartName) AS 'Total Made' FROM Parts_List
WHERE userID IN (select userID from warehouse1)
GROUP BY PartName, WorkerName
I figured out how to get the PartName as columns by creating a matrix and then adding a Dataset with a query like this:
select PartName From Parts_List
However, I can't figure out how to get the rows of workers and their Count(PartName) to line up with the columns.
Does SSRS even support this?
Thanks!

Using the query you have it is possible get the required matrix using this data arragement:
Add a matrix to the report surface, in Column Group add PartName column and add Worker Name to Row Groups. To show Total made add it in the below PartName cell.
It will produce this:

SQL ORDER BY using a value in another table using an equation grouped by duplicates

I have been given a movie database and I am trying to order by user rating held in a separate table to my movie information.
My problem is that my database does NOT have an overall rating of a movie, but only singular user ratings attached to that movie. But I want to order it by the overall average rating
For example:
SELECT Movies.title, Movies.movie_id, Movies.poster, Ratings.rating
FROM Movies INNER JOIN Ratings
ON Movies.movie_id = Ratings.movie_id
WHERE genre LIKE '%action%' AND (origin = 'american')
ORDER BY Ratings.rating DESC;
*(Rating is only selected to showcase to you the values, I do not need to use them outside this query)
This works out to display
+-------------------------+----------+------------------------------------+--------+
| title | movie_id | poster | rating |
+-------------------------+----------+------------------------------------+--------+
| The Baytown Outlaws | 2 | posters/The Baytown Outlaws.jpg | 5 |
| A Dark Truth | 8 | posters/A Dark Truth.jpg | 4 |
| A Dark Truth | 8 | posters/A Dark Truth.jpg | 3 |
| American Made | 14 | posters/American Made.jpg | 3 |
| Avengers: Age of Ultron | 4 | posters/Avengers Age of Ultron.jpg | 3 |
| Romeo Must Die | 1 | posters/Romeo Must Die.jpg | 3 |
| Avengers: Age of Ultron | 4 | posters/Avengers Age of Ultron.jpg | 2 |
| Fast & Furious 6 | 3 | posters/Fast & Furious 6.jpg | 2 |
| Olympus Has Fallen | 9 | posters/Olympus Has Fallen.jpg | 1 |
+-------------------------+----------+------------------------------------+--------+
Now from this I want to have my query select groups based on movie title, add up the ratings of that group, average that value, and then order titles by that average and excluding duplicate title names from the return
So my ideal query would return:
+-------------------------+----------+------------------------------------+
| title | movie_id | poster |
+-------------------------+----------+------------------------------------+
| The Baytown Outlaws | 2 | posters/The Baytown Outlaws.jpg |
| A Dark Truth | 8 | posters/A Dark Truth.jpg |
| American Made | 14 | posters/American Made.jpg |
| Romeo Must Die | 1 | posters/Romeo Must Die.jpg |
| Avengers: Age of Ultron | 4 | posters/Avengers Age of Ultron.jpg |
| Fast & Furious 6 | 3 | posters/Fast & Furious 6.jpg |
| Olympus Has Fallen | 9 | posters/Olympus Has Fallen.jpg |
+-------------------------+----------+------------------------------------+
So this returns my movie info ordered by average rating then excluding duplicate titles
Baytown Outlaws has 1 rating at 5 -> overall 5
Dark Truth has 2 ratings at 4 and 3 -> overall rating of 3.5 but only displays one row of movie info
American Made has 1 rating at 3 -> overall 3
etc.
I am having a lot of trouble figuring out this exact query, or if it is even possible. Any help or keyword suggestion would be useful as I am somewhat new to SQL and don't know all of its strengths. If not possible, I would also appreciate an answer saying so, so that I can go ahead and rework the database system to instead follow a better system of saving the overall rating within the Movies table.
A combination of COUNT(*) and SUM(rating) group by movie_id (or title).
Something like this:
SELECT Movies.title, Movies.movie_id, Movies.poster, SUM(Ratings.rating)/COUNT(*) AS avg_rating
FROM Movies INNER JOIN Ratings
ON Movies.movie_id = Ratings.movie_id
WHERE genre LIKE '%action%' AND (origin = 'american')
GROUP BY Movies.movie_id ORDER BY avg_rating DESC;
It can be done with the AVG function and a group by on multiple columns.
The tricky part of using AVG in that case is that when using such a function, every element in the SELECT part must either be in the GROUP or be an aggregate function. That being said, If you make groups by a combination of ID and Movie title, you would obtain the same result (in this case) as if you grouped by ID only.
You can use that to your advantage to add these columns in your SELECT section while using the AVG aggregate function.
In your first table, every time you look at the A Dark Truth movie, it comes with the same id, 8. Every time you look at the value Avengers: Age of Ultron, it comes with the same id, 4.
I suggest taking a few minutes and drawing a Venn diagram of the problem to get a good grasp of it as it seems this is material of a class.
I made a fiddle to demonstrate it for you. You can play around with it and add your initial join and where to complete it, I did a slight variation of the initial model, the create table is also in the fiddle.
SELECT Movie_id, Title, Poster, AVG(Rating)
FROM MoviesRatings
GROUP BY Movie_id, Title, Poster
ORDER BY AVG(Rating) DESC

SSRS: Using tablix with multiple Dataset

I have two datasets:
My First dataset (Students) looks like this:
Student_Name| ID
Jack Luis | 1
Adam Bob | 2
And my second dataset (Exam) looks like this:
Student_ID | Exam | Note
1 | Java | 15
1 | Php | 14
2 | Java | 12
2 | Php | 13
I want to get this in the same Tablix:
Student Name | ID
Jack Luis | 1
Adam Bob | 2
Student_ID | Student Name | Exam | Note
1 |Jack Luis | Java | 15
1 |Jack Luis | Php | 14
2 |Adam Bob | Java | 12
2 |Adam Bob | Php | 13
Thank You Mr alejandro zuleta
but i want the result like this in the same Tablix (using groupin By Name)
Studant Name:Jack Luis
Exam | Note
Java | 15
Php | 14
Studant Name:Adam Bob
Exam | Note
Java | 12
Php | 13
I think this can be solved using LOOKUP function. LOOKUP function joins multiple dataset using a common field in the involved datasets.
Create a tablix and set the DataSetName property to your second dataset.
Drag and drop the fields to the columns you want to show. For the Student Name column use the following expression:
=Lookup(Fields!Student_id.Value,Fields!Student_id.Value,Fields!StudentName.Value,"DataSet21")
In the above expression replace DataSet21 by the actual name of your
first dataset.
It will preview something like this:
UPDATE: Grouping by a header row.
Add a tablix and set your second dataset in DataSetName property. Add Exam and Note fields to the corresponding columns.
Add a Parent Row Group.
In the Tablix group window select the Add group header checkbox and use the following expression:
=Lookup(Fields!Student_id.Value,
Fields!Student_id.Value,Fields!StudentName.Value,"DataSet21")
Delete the first column created by the previous grouping setting.
In the cell above Exam use the following expression:
="Student Name: " &
Lookup(Fields!Student_id.Value,Fields!Student_id.Value,Fields!StudentName.Value,"FirstDataSet")
Now select Exam and Note row and add a row above outside the group.
Type Exam and Note in the corresponding cell above [Exam] and [Note] fields.
Select the three cells in the first row, right click it and select Merge Cells.
It will preview something like this:
If you want to delete the first blank row, you can do it smoothly.
Let me know if this helps.

SSRS Single row for Grouping

I'm working with SharePoint Lists, I have 2 Lists for this issue i.e. Movies & Theatres. Only one list is used tough, because Theatres reference a movie.
(I know this is weird but I'm not actually working with movies and theatres, it's just using an analogy so anyone could understand the problem so let's assume each Theatre only plays a single movie :-P )
So from the Theatres list I create a dataset with following fields: Linked_Movie (Title), Country, Theatre_Number.
I want to create a report that shows a tablix that lists all Movie-titles with all the countries it's shown in and a count of the theatres that are playing that movie. So the tablix should look like example below:
MovieTitle | Country | # of theatres
| |
Movie 1 | Country A | 5
| Country B | 10
SubTotal | 2 | 15
| |
Movie 2 | Country C | 15
SubTotal | 1 | 15
| |
Total | 3 | 30
I have already created a tablix which groups on Linked_Movie first and Country second. Then in the details-section I just count the theatres that play that certain movie in that specific country. To achieve this I created a second dataset with the exact same data so I could use LookUpSet.Length. But even though my calculations are correct the tablix still generates a row for each individual theatre. So my tablix actually looks like example below:
MovieTitle | Country | # of theatres
| |
Movie 1 | Country A | 5
| | 5
| | 5
| | 5
| | 5
.... | ... | ...
So if anyone knows how I would be able to achieve a tablix like the first example that would be greatly appreciated.
If anything is still unclear please don't hesitate to ask.
Kind regards
Gravinco
I was able to solve it by adding a calculated field to the dataset named MovieCountry.
After this I put the expression below as the condition for 'Row visibility' and the visiblity of the '=(Details)' properties:
=iif(Fields!MovieCountry.Value = Previous(Fields!MovieCountry.Value), True, False)
This way I only get a single row for each movie and country combination.
Any questions are always welcome!

Select rows which do not have the first column matching any other rows

I need to select the rows that do not have the first column matching. For example, from the data below;
Person | Room
---------------------------------------
ben | 1
jake | 3
jake | 1
steven | 2
james | 1
james | 2
james | 3
The query would only return these rows:
Person | Room
---------------------------------------
ben | 1
jake | 3
steven | 2
james | 1
It doesn't matter what value the room column returns.
And it needs to be able to work with increasing room numbers and different names.
I've had no look searching for a answer and can't figure out how to do it, however it might be my current mindset and it might be really easy to do.
SELECT Person, MIN(Room) AS Room
FROM YourTable
GROUP BY Person
And if you can guarantee that the ONLY_FULL_GROUP_BY setting will always be turned off, the following is also possible in MySql:
SELECT Person, Room
FROM YourTable
GROUP BY Person
But I'd use the MIN() function just to be safe...

MySQL query to compare content of one column with title of other column

I know the title makes no sense at first glance. But here's the situation: the DB table is named 'teams'. In it, there are a bunch of columns for positions in a soccer team (gk1, def1, def2, ... , st2). Each column is type VARCHAR and contains a player's name. There is also a column named 'captain'. The content of that column (not the most fortunate solution) is not the name of the captain, but rather the position.
So if the content of 'st1' is Zlatan Ibrahimovic and he's the captain, then the content of 'captain' is the string 'st1', and not the string 'Zlatan Ibrahimovic'.
Now, I need to write a query which gets a row form the 'teams' table, but only if the captain is Zlatan Ibrahimovic. Note that at this point I don't know if he plays st1, st2 or some other position. So I need to use just the name in the query, to check if the position he plays on is set as captain. Logically, it would look like:
if(Zlatan is captain)
get row content
In MySQL, the if condition would actually be the 'where' clause. But is there a way to write it?
$query="select * from teams where ???";
The "Teams" table structure is:
-----------------------------------------------------------------
| gk1 | def1 | def2 | ... | st2 | captain |
-----------------------------------------------------------------
| player1 | player2 | player3 | ... | playerN | captainPosition |
-----------------------------------------------------------------
Whith all fields being of VARCHAR type.
Because the content of the captain column is the position and not the name, and you want to choose based on the position, this is trivial.
$query="select * from teams where captain='st1'";
Revised following question edit:
Your database design doesn't allow this to be done very efficiently. You are looking at a query like
SELECT * FROM teams WHERE
(gk1='Zlatan' AND captain='gk1') OR
(de1='Zlatan' AND captain='de1') OR
...
The design mandates this sort of query for many functions: how you can find the team which a particular player plays for without searching every position? [Actually you could do that by finding the name in a concatenation of all the positions, but it's still not very efficient or flexible]
A better solution would be to normalise your data so you had a single table showing which player was playing where:
Situation
Team | Player | Posn | Capt
-----+--------+------+------
1 | 12 | 1 | 0
1 | 11 | 2 | 1
1 | 13 | 10 | 0
...with other tables which allow you to identify the Team, Player and Postion referenced here. There would need to be some referential checks to ensure that each team had only one captain, and only plays one goalkeeper, etc.
You could then easily see that the captain of Team 1 is Player 11 who plays in position 2; or find the team (if any) for which player 11 is captain.
SELECT Name FROM Teams
WHERE Situation.Team = Teams.id
AND Situation.Capt = 1
AND Situation.Player = Players.id
AND Players.Name = 'Zlatan';
A refinement on that idea might be
Situation
Team | Player | Posn | Capt | Playing
-----+--------+------+------+--------
1 | 12 | 1 | 0 | 1
1 | 11 | 2 | 1 | 1
1 | 13 | 10 | 0 | 0
1 | 78 | 1 | 0 | 0
...so that you could have two players who are goalkeepers (for example) but only field of them.
Redesigning the database may be a lot of work; but it's nowhere near as complicated or troublesome as using your existing design. And you will find that the performance is better if you don't need to use inefficient queries.
By what have you exposed, you just need to put the two conditions and check if the query returned 1 record. If it returns no records, he is not the captain:
SELECT *
FROM Teams
WHERE name = 'Zlatan Ibrahimovic' AND position = 'st1';
