SQL Server 2008, concatenating Strings? - sql

I have wasted my 2 whole days to trying to resolve this issue, Now I am going out of my mind, I need an urgent Help,
The Issue is,
I Have To Tables
Table: Sales, SalesId is primary key
---------------------------------------------------
SalesId | SalesDate | Customer| Discount | Remarks
---------------------------------------------------
1 | 01/01/2012| John | 15 | NULL
2 | 01/01/2012| Peter | 25 | NULL
3 | 01/01/2012| Micheal | 35 | NULL
Table: SalesBody, SerialNo is primary key and SalesId is foreign key
---------------------------------------------------
SerialNo | SalesId | Product | Quantity | Rate
---------------------------------------------------
10 | 1 | Pencil | 18 | 20
11 | 1 | pen | 200 | 60
12 | 1 | Rubber | 150 | 10
13 | 1 | Paper | 500 | 2
14 | 2 | Mouse | 15 | 190
15 | 2 | KeyBoard | 10 | 600
16 | 2 | Monitor | 5 | 2000
17 | 3 | Mobile | 2 | 15000
Now I want to make a query which can make the result like following
----------------------------------------------------------------------------
SalesId | SalesDate | Details | Amount
----------------------------------------------------------------------------
1 | 01/01/2012 | Sold: Pencil x 18 # 20, Pen x 200 # 60| xxxxxxx
| | Rubber x 150 # 10, Paper x 500 # 2 |
2 | 01/01/2012 | Sold: Mouse x 15 # 190, Keyboard x 10 |
| | # 600, Monitor x 5 # 2000 | xxxxxxx
3 | 01/01/2012 | Sold: Mobile x 2 # 15000 | xxxxxxx
I have tried different techniques eg. Coalesce, Stuff, For XML PATH('')
I could not Concatenate the Detail String.

As far as I can see you just need to pivot the SalesBody table and group by SalesID
Something along the lines of the below query should do the trick
select sb.SalesId, ( SELECT ', ' + sb2.Product + ' x ' + sb2.Quantity + ' # ' + sb2.Rate
FROM SalesBody sb2
WHERE sb2.SalesId = sb.SalesId
FOR XML PATH('') ) AS Details
from SalesBody sb
group by sb.SalesId
Then just join that query with your Sales table to get the other data and do a STUFF command on Details in the query above to remove the leading "," and add your "sold: " string and you should be all good to go.

Generate 'average' column from sub query and ROW_NUMBER window function in SQL SELECT

I have the following SQL Server tables (with sample data):
Questionnaire
id | coachNodeId | youngPersonNodeId | complete
1 | 12 | 678 | 1
2 | 12 | 52 | 1
3 | 30 | 99 | 1
4 | 12 | 678 | 1
5 | 12 | 678 | 1
6 | 30 | 99 | 1
7 | 12 | 52 | 1
8 | 30 | 102 | 1
Answer
id | questionnaireId | score
1 | 1 | 1
2 | 2 | 3
3 | 2 | 2
4 | 2 | 5
5 | 3 | 5
6 | 4 | 5
7 | 4 | 3
8 | 5 | 4
9 | 6 | 1
10 | 6 | 3
11 | 7 | 5
12 | 8 | 5
ContentNode
id | text
12 | Zak
30 | Phil
52 | Jane
99 | Ali
102 | Ed
678 | Chris
I have the following T-SQL query:
SELECT
Questionnaire.id AS questionnaireId,
coachNodeId AS coachNodeId,
coachNode.[text] AS coachName,
youngPersonNodeId AS youngPersonNodeId,
youngPersonNode.[text] AS youngPersonName,
ROW_NUMBER() OVER (PARTITION BY Questionnaire.coachNodeId, Questionnaire.youngPersonNodeId ORDER BY Questionnaire.id) AS questionnaireNumber,
score = (SELECT AVG(score) FROM Answer WHERE Answer.questionnaireId = Questionnaire.id)
FROM
Questionnaire
LEFT JOIN
ContentNode AS coachNode ON Questionnaire.coachNodeId = coachNode.id
LEFT JOIN
ContentNode AS youngPersonNode ON Questionnaire.youngPersonNodeId = youngPersonNode.id
WHERE
(complete = 1)
ORDER BY
coachNodeId, youngPersonNodeId
This query outputs the following example data:
questionnaireId | coachNodeId | coachName | youngPersonNodeId | youngPersonName | questionnaireNumber | score
1 | 12 | Zak | 678 | Chris | 1 | 1
2 | 12 | Zak | 52 | Jane | 1 | 3
3 | 30 | Phil | 99 | Ali | 1 | 5
4 | 12 | Zak | 678 | Chris | 2 | 4
5 | 12 | Zak | 678 | Chris | 3 | 4
6 | 30 | Phil | 99 | Ali | 2 | 2
7 | 12 | Zak | 52 | Jane | 2 | 5
8 | 30 | Phil | 102 | Ed | 1 | 5
To explain what's happening here… There are various coaches whose job is to undertake questionnaires with various young people, and log the scores. A coach might, at a later date, repeat the questionnaire with the same young person several times, hoping that they get a better score. The ultimate goal of what I'm trying to achieve is that the managers of the coaches want to see how well the coaches are performing, so they'd like to see whether the scores for the questionnaires tend to go up or not. The window function represents a way to establish how many times the questionnaire has been undertaken by the same coach/young person combo.
I need to be able to determine the average score based on the questionnaire number. So for example, the coach 'Zak' logged scores of '1' and '3' for his first questionnaires (where questionnaireNumber = 1) so the average would be 2. For his second questionnaires (where questionnaireNumber = 2) the scores were '3' and '5' so the average would be 4. So in analysing this data we know that over time Zak's questionnaire scores have improved from an average of '2' the first time to an average of '4' the second time.
I feel like the query needs to be grouped by the coachNodeId and questionnaireNumber values so it would output something like this (I've ommitted the questionnaireId, youngPersonNodeId, youngPersonName and score columns as they aren't crucial for the output — they're only used to derive the averageScore — and wouldn't be useful the way the results are grouped):
coachNodeId | coachName | questionnaireNumber | averageScore
12 | Zak | 1 | 2 (calculation: (1 + 3) / 2)
12 | Zak | 2 | 4 (calculation: (3 + 5) / 2)
12 | Zak | 3 | 4 (only one value: 4)
30 | Phil | 1 | 5 (calculation: (5 + 5) / 2)
30 | Phil | 2 | 2 (only one value: 2)
Could anyone suggest how I can modify my query to output the average scores based on the score from the sub-query and the ROW_NUMBER window function? I've hit the limits of my SQL skills!
Many thanks.
It is a bit hard to tell without sample data, but I think you are describing aggregation:
SELECT q.coachNodeId AS coachNodeId,
cn.[text] AS coachName,
q.youngPersonNodeId AS youngPersonNodeId,
ypn.[text] AS youngPersonName,
AVG(score)
FROM Questionnaire q JOIN
ContentNode cn
ON q.coachNodeId = cn.id JOIN
ContentNode ypn
ON q.youngPersonNodeId = ypn.id LEFT JOIN
Answer a
ON a.questionnaireId = q.id
WHERE complete = 1
GROUP BY q.coachNodeID, cn.[text] AS coachName,
q.youngPersonNodeId, ypn.[text]

How to join transactional data with customer data tables and perform case-based operations in SQL

I'm trying to perform a query between two different tables and come up with a case by case scenario, coming up with a list of records of calls for a specific month.
Here are my tables:
Customer table:
+----+----------------+------------+
| id | name | number |
+----+----------------+------------+
| 1 | John Doe | 8973221232 |
| 2 | American Dad | 7165531212 |

What am I trying to accomplish?
I'm trying to compile a list of "costs" for each of the customers that made calls on July 2018. The costs are based on:
1) If the customer received a call (incoming), the cost of the call is equal to the duration;
2) if the customer made a call (outgoing), the cost of the call is 100 if the call is 30 or less in duration. If it exceeds 30 duration, then the cost is 100 plus 5 * duration of the exceeded period.
If the customer didn't make any calls during that month he shouldn't be on the list.
Examples:
1) Customer American Dad has 3 incoming calls and 1 outgoing call, however only trans_id 10 and 13 are for the month of July. He should be paying a total of 538:
for trans_id 10 = 450 (100 for the first 30s + 5 * 70 for the remaining)
for trans_id 13 = 88
2) Customer Samuel Gatsby has 1 incoming call and 3 outgoing calls, however only trans_id 8 and 11 are for the month of July. He should be paying a total of 722:
for trans_id 8 = 345 (100 for the first 30s + 5 * 49 for the remaining)
for trans_id 11 = 377
Considering only these two examples, the output would be:
+----+----------------+------------+------------+
| id | name | number | billable |
+----+----------------+------------+------------+
| 2 | American Dad | 7165531212 | 538 |
| 4 | Samuel Gatsby | 9197543321 | 722 |
+----+----------------+------------+------------+
Note: Mike Chat shouldn't be on the list as he didn't make or receive any calls for that specific month.
What have I tried so far?
I've been playing cat and mouse with this one, I'm using the number as uniqueID, already attempted both a full outer join and combining where incoming or outgoing is not null then applying rules by case, tried doing a left join and applying cases, but I'm circling around and I can't get to a final list. Whenever I get incoming or outgoing, I'm either not able to apply the case or not able to come with both together. Really appreciate the help!
select customer_name.name, customer_name.number, bill = (CASE
WHEN customer_name.number = transaction_data.incoming then 'sum bill'
else 'multiply and add'
end)
from customer_name
left join transaction_data on customer_name.number = transaction_data.incoming or customer_name.name = transaction_data.outgoing
where strftime('%Y-%m', transaction_data.date_time) = '2018-07'
Note: I'm using sqlite to try it out online but the database is on SQL Server 2012, so I know that I can use a date format much easier, that way, but I'd like to keep as close to T-SQL as possible.
Also tried creating a case to determine whether it's incoming call or outgoing, but I'm only getting incoming as a result, even though trans_id 10 is outgoing:
select name, number, duration, case
when customer_name.number = transaction_data.incoming then 'incoming'
when customer_name.number = transaction_data.outgoing then 'outgoing'
END direction
from customer_name
left join transaction_data on customer_name.number = transaction_data.incoming or customer_name.name = transaction_data.outgoing
where strftime('%Y-%m', transaction_data.date_time) = '2018-07'
Try this:
SELECT
c."name", c.number,
SUM(CASE c.number
WHEN t.incoming THEN t.duration
ELSE IIF(t.duration - 30 < 0, 0, t.duration - 30) * 5 + 100
END) AS billable
FROM Customer AS c INNER JOIN [Transaction] AS t
ON c.number IN(t.incoming, t.outgoing)
WHERE t.date_time >= '20180701' AND t.date_time < '20180801'
GROUP BY c."name", c.number
Output:
| name | number | billable |
+---------------+------------+----------+
| John Doe | 8973221232 | 440 |
| American Dad | 7165531212 | 538 |
| Michael Clean | 8884731234 | 774 |
| Samuel Gatsby | 9197543321 | 722 |

SQL group column where other column is equal

I'm trying to select some information from a database.
I get a database with columns like:
Ident,Name,Length,Width,Quantity,Planned
Table data is as follow
+-----------+-----------+---------+---------+------------+---------+
| Ident | Name | Length | Width | Quantity | Planned |
+-----------+-----------+---------+---------+------------+---------+
| 12345 | Name1 | 1500 | 1000 | 20 | 5 |
| 23456 | Name1 | 1500 | 1000 | 30 | 13 |
| 34567 | Name1 | 2500 | 1000 | 10 | 2 |
| 45678 | Name1 | 2500 | 1000 | 10 | 4 |
| 56789 | Name1 | 1500 | 1200 | 20 | 3 |
+-----------+-----------+---------+---------+------------+---------+
my desired result, would be to group rows where "Name,Length and Width" are equal, sum the "Quantity" and reduce it by the sum of "Planned"
e.g:
- Name1,1500,1000,32 --- (32 because (20+30)-(5+13))
- Name1,2500,1000,14 --- (14 because (10+10)-(2+4)))
- Name1,1500,1200,17
now I got problems how to group or join these information to get the wished select. may be some you of can help me.. if further information's required, please write it in comment.
You can achieve it by grouping your table and subtract sums of Quantity and Planned.
select
Name
,Length
,Width
,sum(Quantity) - sum(Planned)
from yourTable
group by Name,Length,Width
select
A1.Name,A1.Length,A1.Width,((A1.Quantity + A2.Quantity) -(A1.Planned+A2.Planned))
from `Table` AS A1, `Table` AS A2
where A1.Name = A2.Name and A1.Length = A2.Length and A1.Width = A2.Width
group by (whatever)
So you are comparing these columns form the same table?

Can't figure out a simple SQL query

Might be very simple, but I've been digging fow a few days now... I just can't figure out how to make this SQL query in Access...
In reference to the tables below, i'm looking for the query that can extract all the ITEMS for a specific Shop (ie 1:Alpha) from a specific GROUP (ie 1:Tools), that are NOT in the report for 2014... in this case ITEMS.IDs 6, 8, 9 and 10!
Tables:
Years
ID | Year
-----------------------------------------------
1 | 2014
2 | 2015
Shops
ID | ShopName
-----------------------------------------------
1 | Alpha
2 | Bravo
Items
ID | StockNbr | Description | GroupID
-----------------------------------------------
1 | 00-1200 | Ratchet 1/4 | 1
2 | 00-1201 | Ratchet 1/2 | 1
3 | 00-1300 | Screwdriver Philips No1 | 1
4 | 01-5544 | Banana | 2
5 | 00-4457 | Apple | 2
6 | 21-8887 | Hammer | 1
7 | 21-6585 | Drill | 1
8 | 21-4499 | Multimeter | 1
9 | 21-5687 | Digital Caliper | 1
10 | 22-7319 | File Set | 1
...
Groups
ID | GroupName
-----------------------------------------------
1 | Tools
2 | Fruits
REPORTS
ID | YearID | ShopID | ItemID
-----------------------------------------------
1 | 1 | 1 | 1
2 | 1 | 1 | 2
3 | 1 | 1 | 3
4 | 1 | 1 | 4
5 | 1 | 1 | 7
6 | 1 | 2 | 5
7 | 1 | 2 | 8
8 | 1 | 2 | 10
I've tried this, but then I realize it doesn't take the shops into consideration, it'll list all items that are not listed in reports, so if reports has an item for shop 2, it won't list it either...
SELECT Items.ID, Items.StockNbr, Items.Description, Items.GroupID, Reports.YearID, Reports.ShopID
FROM Reports
RIGHT JOIN Items ON Reports.ItemID = Items.ID
WHERE (((Items.GroupID)=1) AND ((Reports.UnitID) Is Null))
ORDER BY Items.StockNbr;
Thank you!
I think you're looking for an anti-join. There are several ways to do this. Here's one using not in.
select i.* from items i
where i.GroupId = 1
and i.ID NOT IN (
select ItemID from reports r
where r.ShopID = 1
and r.YearID = 2014
)
If the table Reports does not reference Items.ID then there is no available relationship ShopID or YearID
select *
from items
left join reports on items.id = reports.itemid
where reports.itemid IS NULL

SQL Server 2008 - accumulating column

I would like to accumulate my data as you can see below there is origin table table1:
What is the best query for to do this?
Is possible to do this dynamically - when I add more types of terms??
Table 1
ID | term | value
-----------------------
1 | I | 100
2 | I | 200
3 | II | 100
4 | II | 50
5 | II | 75
6 | III | 50
7 | III | 65
8 | IV | 30
9 | IV | 45
And the result should be like below:
YTD | Acc Value
------------------
I-I | 300
I-II | 525
I-III| 640
I-IV | 715
Thanks
select
(select min(term) from yourtable ) +'-'+term,
(select sum(value) from yourtable t1 where t1.term<=t.term)
from yourtable t
group by term
