Let's say I have these 2 tables:
ArticleTBL
+---------+----------+-------------+------------+
|articleid| typeid | price | user |
+---------+----------+-------------+------------+
| 0 | 2 | 1 | 122 |
| 1 | 3 | 2 | 344 |
| 2 | 3 | 1 | 455 |
| 3 | 1 | 4 | 34 |
+---------+----------+-------------+------------+
TypeTBL
+---------+----------+-------------+
|typeid | type | factory |
+---------+----------+-------------+
| 0 | wooden | factry1 |
| 1 | plastic | factry2 |
| 2 | metal | factry3 |
| 3 | sth. | factry4 |
+---------+----------+-------------+
How do I request all this information only with articleid for each row?
Isn't this what you want? Read more
SELECT a.articleid,
a.price.a.USER,
t.typeid,
t.type,
t.factory
FROM form ArticleTBL a
INNER JOIN typetbl t
ON a.typeid = t.typeid

I have a table like this:
+----+----------+----------+-----------+
| ID | Name | Is_Group | Parent_id |
+----+----------+----------+-----------+
| 1 | Clothes | 1 | Null |
| 2 | Food | 1 | Null |
| 3 | fastfood | 1 | 2 |
| 4 | T-shirt | 0 | 1 |
| 5 | skirt | 0 | 1 |
| 6 | pizza | 0 | 3 |
| 7 | snack | 0 | 3 |
+----+----------+----------+-----------+
I would like to have a horizontal representation to use for reporting such as:
+----+---------+---------+----------+
| ID | Name | level1 | level2 |
+----+---------+---------+----------+
| 4 | T-shirt | Clothes | Null |
| 5 | skirt | Clothes | Null |
| 6 | pizza | Food | fastfood |
| 7 | snack | Food | fastfood |
+----+---------+---------+----------+
Would anyone know how to do this?
You can use two levels of left join:
select t.*,
coalesce(tpp.name, tp.name) as level1,
(case when tpp.name is not null then tp.name end) as level2
from t left join
t tp
on t.parent_id = tp.id left join
t tpp
on tp.parent_id = tpp.parent_id
where not exists (select 1
from t tc
where tc.parent_id = t.id);
I have 3 tables:
+-----+---------+
|cl_id| name |
+-----+---------+
| 1 | adaf |
| 2 | rich | - clients
| 3 | call |
| 4 | alen |
| 5 | courney |
| 6 | warren |
+-----+---------+
+-----+---------+
|cl_id| data |
+-----+---------+
| 1 | 13 |
| 2 | 1000 | - table1
| 5 | 0 |
| 6 | 0 |
+-----+---------+
+-----+---------+
|cl_id| data |
+-----+---------+
| 2 | -355 | - table2
| 3 | 35 |
| 3 | 10 |
| 5 | 46 |
| 5 | 50 |
| 5 | 10 |
+-----+---------+
And I have to combine those three tables, so the result should be:
+-----+---------+--------+---------+
|cl_id| name |data_tb1|data_tb2 |
+-----+---------+--------+---------+
| 1 | adaf | 13 | 0 |
| 2 | rich | 1000 | -355 |
| 3 | call | 0 | 45 |
| 4 | alen | 0 | 0 |
| 5 | courney| 0 | 106 |
| 6 | warren | 0 | 0 |
+-----+---------+--------+---------+
It should output all clients and theirs SUM(data) from table1 and table2. clients goes one-to-more.
Thanks in advance
Simply using LEFT JOIN and GROUP BY
SELECT c.cl_id,
c.name,
COALESCE(SUM(t1.data), 0) AS data_tb1,
COALESCE(SUM(t2.data), 0) AS data_tb2
FROM clients c
LEFT JOIN table1 t1 ON c.cl_id = t1.cl_id
LEFT JOIN table2 t2 ON c.cl_id = t2.cl_id
GROUP BY c.cl_id,
c.name
ORDER BY c.cl_id;
If you are using SQL Server then simple Use Left Join as below :
SELECT C.cl_id,
C.name,
SUM(ISNULL(T.data, 0)) data_tb1,
SUM(ISNULL(T1.data, 0)) data_tb2
FROM
(
SELECT *
FROM clients
) C
LEFT JOIN table1 T ON T.cl_id = C.cl_id
LEFT JOIN table2 T1 ON T1.cl_id = C.cl_id
GROUP BY C.cl_id,
C.name
ORDER BY C.cl_id;
Desired Output :
+-----+---------+--------+---------+
|cl_id| name |data_tb1|data_tb2 |
+-----+---------+--------+---------+
| 1 | adaf | 13 | 0 |
| 2 | rich | 1000 | -355 |
| 3 | call | 0 | 45 |
| 4 | alen | 0 | 0 |
| 5 | courney| 0 | 106 |
| 6 | warren | 0 | 0 |

The scenario I am working on is as follows:-
A number of interviews are conducted a food poisoning case
A query called qryFoodInCase ( fldCaseID, fldFood) is generate consisting of all the food mentioned in all the interviews
An other query call qryFoodInInterview( fldCaseID, fldInterviewID, fldFood) consist of the food mentioned in each Interview
Now I am after the sql for a query that will return the food that was not consumed by an interviewee but consumed by one or more other interviewees.
The closest I've got is:
select Q1.fldCaseID,Q1.fldfood,Q2.fldInterviewID,fldGotSick
from qryFoodInCases as Q1
left join
(select * from qryFoodInInterview where qryFoodInInterview.fldInterviewID=1) as Q2
on Q1.fldFood=Q2.fldFood
where Q1.fldCaseID=1
The field Q2.fldInterviewID returns 1 for the food consumed and null for the food not consumed. However, I don't want to hard code the fldInterviewID in the sql. I would like a similar recordset returned for all the interviews in one query.
The SQL for qryFoodInCase and qryFoodInInterview are as follows:-
CREATE VIEW `qryFoodInCases`
AS
SELECT tblCases.fldCaseID
,fldfood
,count(tblFoodHistory.fldFoodID) AS fldFoodFrequency
FROM tblFood
INNER JOIN tblFoodHistory
ON tblFoodHistory.fldFoodID = tblFood.fldFoodID
INNER JOIN tblMealHistory
ON tblFoodHistory.fldMealID = tblMealHistory.fldMealHistoryID
INNER JOIN tblInterviews
ON tblInterviews.fldInterviewID = tblMealHistory.fldInterviewID
INNER JOIN tblCases
ON tblCases.fldCaseID = tblInterviews.fldCaseID
GROUP BY tblCases.fldCaseID, tblFood.fldFood
OUTPUT:
+-----------+------------+------------------+
| fldCaseID | fldFood | fldFoodFrequency |
+-----------+------------+------------------+
| 1 | Banana | 3 |
| 1 | Beans | 5 |
| 1 | Cabagge | 3 |
| 1 | Chicken | 1 |
| 1 | Pork | 5 |
| 1 | Potatoes | 1 |
| 1 | Rice | 1 |
| 1 | fried fish | 1 |
| 2 | Cabagge | 1 |
| 2 | Chicken | 2 |
| 2 | Potatoes | 1 |
| 2 | Rice | 1 |
| 2 | Salad | 1 |
+-----------+------------+------------------+
and
CREATE VIEW `qryFoodInInterview`
AS
SELECT tblInterviews.fldCaseID
,tblInterviews.fldInterviewID
,tblFood.fldFood
,tblInterviews.fldGotSick
FROM tblInterviews
INNER JOIN tblMealHistory
ON tblInterviews.fldInterviewID = tblMealHistory.fldInterviewID
INNER JOIN tblFoodHistory
ON tblFoodHistory.fldMealID = tblMealHistory.fldMealHistoryID
INNER JOIN tblFood
ON tblFood.fldFoodID = tblFoodHistory.fldFoodID
GROUP BY tblInterviews.fldInterviewID, tblFoodHistory.fldFoodID
OUTPUT
+-----------+----------------+------------+------------+
| fldCaseID | fldInterviewID | fldFood | fldGotSick |
+-----------+----------------+------------+------------+
| 1 | 1 | Pork | 0 |
| 1 | 1 | Banana | 0 |

SQL Fiddle Demo
create a cross join off all food with all interviewrs
then a left join to see which one didnt had interview
the null mean interview didnt consume food
and exists mean someone different to interview consume food
.
SELECT F.fldFood, I.fldInterviewID, FI.fldInterviewID
FROM qryFoodInCases F, (SELECT DISTINCT fldInterviewID FROM qryFoodInInterview) I
LEFT JOIN qryFoodInInterview FI
ON F.fldFood = FI.fldFood
AND I.fldInterviewID = FI.fldInterviewID
WHERE FI.fldInterviewID IS NULL
AND EXISTS (SELECT 1
FROM qryFoodInInterview Q1
WHERE Q1.fldFood = F.fldFood
AND Q1.fldInterviewID <> I.fldInterviewID)
;
The trick was do the thing one step at the time. Once I realize I need all the combinations and create the cross join, the rest was easy.
select Q1.fldCaseID,Q1.fldfood,Q2.fldInterviewID,fldGotSick
from qryFoodInCases as Q1
left join
(select * from qryFoodInInterview QF1
JOIN qryFoodInInterview QF2
where QF1.fldInterviewID <> QF2.fldInterviewID
AND QF1.fldInterviewID > QF2.fldInterviewID
) as Q2
on Q1.fldFood=Q2.fldFood
where Q1.fldCaseID=1
As you mentioned you want to duplicate the items FoodInterviews, self JOIN will suffice your question. Please try this out , caution I didn't tested it.
Fixing Missed Self Join Condition to fix duplicates.
I have a table structure for SalesItems, and Sales.
SalesItems is setup something like this
| SaleItemID | SaleID | ProductID | ProductType |
| 1 | 1 | 1 | 1 |
| 2 | 1 | 2 | 2 |
| 3 | 1 | 15 | 1 |
| 4 | 2 | 5 | 2 |
| 5 | 3 | 1 | 1 |
| 6 | 3 | 8 | 5 |
And Sales is setup something like this
| Sale | Cash |
| 1 | 1.00 |
| 2 | 10.00 |
| 3 | 28.50 |
I am trying to export a basic 'Daily History' that uses joins to spit out the information like this.
| Date | StoreID | Type1Sales | Type2Sales | ... | Cash Taken |
| 5/2 | 50 | 50 | 40 | ... | 39.50 |
| 5/3 | 50 | 10 | 32.50 | ... | 48.50 |
The issue I'm having is if I do an inner join From Sales to Sales Items, I'll end up with this.
| SaleItemID | SaleID | ProductID | ProductType | Sale | Cash |
| 1 | 1 | 1 | 1 | 1 | 1.00 |
| 2 | 1 | 2 | 2 | 1 | 1.00 |
| 3 | 1 | 15 | 1 | 1 | 1.00 |
| 4 | 2 | 5 | 2 | 2 | 10.00 |
| 5 | 3 | 1 | 1 | 3 | 28.50 |
| 6 | 3 | 8 | 5 | 3 | 28.50 |
So if I do a SUM(Cash), then I'll end up returning $70.00, instead of the correct $39.50. I'm not the best with joins, so I've been researching outer joins and such, but none of those seem to work as it's still matching up. Is there a way to only match on the FIRST instance, and return NULL for the rest? For example, something like this
| SaleItemID | SaleID | ProductID | ProductType | Sale | Cash |
| 1 | 1 | 1 | 1 | 1 | 1.00 |
| 2 | 1 | 2 | 2 | 1 | NULL |
| 3 | 1 | 15 | 1 | 1 | NULL |
| 4 | 2 | 5 | 2 | 2 | 10.00 |
| 5 | 3 | 1 | 1 | 3 | 28.50 |
| 6 | 3 | 8 | 5 | 3 | NULL |
Or do you have any other suggestions for returning back the correct amount of Cash for each particular day?
Use DISTINCT(SaleID) in your SELECT to return a single row for each Sale ID.

Each account has multiple locations and each location has multiple RSCs.
I need to get last three RSCs for each location for AccountA.
I have tried the below query:
SELECT tblAccountwiseLocation.LocId,tblAccountwiseLocation.AccId,tblRSCMaster.RSCNo,tblRSCMaster.DateOfAddition FROM tblAccountwiseLocation
INNER JOIN tblRSCMaster ON tblAccountwiseLocation.LocId= tblRSCMaster.LocId
where tblRSCMaster.AccId=1
But not getting the proper output.
Please help me out.
Thank you all in advance.
You can wrap the existing query inside a common table expression, and use ROW_NUMBER() to get only the last 3 (by tblRSCMaster.DateOfAddition) entries per tblAccountwiseLocation.LocId.
WITH cte AS (
SELECT tblAccountwiseLocation.LocId,
tblAccountwiseLocation.AccId,
tblRSCMaster.RSCNo,
tblRSCMaster.DateOfAddition,
ROW_NUMBER() OVER (PARTITION BY tblAccountwiseLocation.LocId
ORDER BY tblRSCMaster.DateOfAddition DESC) rn
FROM tblAccountwiseLocation
INNER JOIN tblRSCMaster
ON tblAccountwiseLocation.LocId = tblRSCMaster.LocId
AND tblAccountwiseLocation.AccId = tblRSCMaster.AccId
WHERE tblRSCMaster.AccId=1
)
SELECT LocId, AccId, RSCNo, DateOfAddition
FROM cte
WHERE rn <= 3
ORDER BY LocId, AccId, DateOfAddition
An SQLfiddle to test with.
Is this what you need?
select m.*
from (select m.*, row_number() over (partition by accID
order by DateOfAddition desc) as seqnum
from tblRSCMaster
where m.locid = 1
) m
where seqnum <= 3
order by AccId, DateOfAddition;
I think you need to filter on the locid rather than on the AccId to get what you want.
