I have 2 tables :
T1:(sales per store)
`Store Sales DateT
A01 100 01-01-22
B01 200 01-01-22
C01 300 01-01-22`
T2 :(store)
`CodeStore Name
A01 Name1
B01 Name2
C01 Name3
D01 Name4`
I want to get all rows of both tables, even if there is no sales in a store.
For ex : in table T1, there's no sales for the store D01 in this date (01-01-22) : but i want to get this record.
expected result :
`Store Sales
A01 100
B01 200
C01 300
D01 `
I'v tried this code, but the store D01 doesn't appear :
`SELECT CodeStore, sum(Sales)
FROM T1
LEFT OUTER JOIN T2 ON CodeStore = Store
where DateT = '01-01-22'
group by CodeStore`
You have to switch the two tables in your query so that all records from T2 will be included. Also, the DateT filter should be in the join criteria (in the ON clause) now since it filters T1.
SELECT CodeStore, sum(Sales)
FROM T2
LEFT OUTER JOIN T1 ON CodeStore = Store AND DateT = '01-01-22'
group by CodeStore
Using a left join (LEFT OUTER JOIN) ensures that even if there isn't a matching row in the joined table (T1), all the rows from the table in the select (T2) will be included in the result.

For example, I have two tables.
Table1:
Schools
Type
City
school1
A
CityA
school2
B
CityB
Table2:
schools
population
time
school1
1000
01/01/2021
school2
2000
01/02/2021
school3
3000
01/03/2021
I want to figure out how to join them like below (without school3):
schools
type
city
population
time
school1
A
CityA
1000
01/01/2021
school2
B
CityB
2000
01/02/2021
I am a beginner and really confused about how to deal with this problem.
http://sqlfiddle.com/#!18/3eaf9/2
You should use JOIN:
SELECT t1.schools, t1.type, t1.city, t2.population, t2.time
FROM
Table1 t1
INNER JOIN
Table2 t2 ON t1.schools = t2.schools
More information how JOIN works you can see in picture in this post
Difference between INNER JOIN and OUTER JOIN see here
I'm inserting rows of data from one table's column to another table's column. This is my work done:
Insert into [Inventory](Cost)
Select cast(a.[CCost] as numeric(18,6)) from [InventoryTemp] as a
Inner join [Inventory] as b on a.[ID] = b.[ID]
I have 10000 rows of data in my [Inventory] table (ID column is filled up) but when the above query was executed, the Cost data started from 10001 until 20000.
Inventory InventoryTemp
ID Cost ID Cost
1 1 3.12
3 3 9.90
18 18 8.80
The result I want
Inventory
ID Cost
1 3.12
3 9.90
18 8.80
If I have read your question correctly, I think you are trying to update the values of the cost column in your Inventory table, based on the values in the InventoryTemp table.
Therefore you want to perform an UPDATE command rather than an INSERT.
An example of this would be:
UPDATE
Inventory
SET
Inventory.Cost = InventoryTemp.Cost
FROM
Inventory
INNER JOIN
InventoryTemp
ON
Inventory.ID = InventoryTemp.ID
For more info please see this question: How do I UPDATE from a SELECT in SQL Server?
You need to use UPDATE instead of `INSERT'
UPDATE i
SET [Cost] = it.[Cost]
FROM [Inventory] i
INNER JOIN [InventoryTemp] it
ON i.ID = it.ID
Try use update.
UPDATE b
SET b.Cost = a.Cost
FROM
[InventoryTemp] as a
Inner join [Inventory] as b on a.[ID] = b.[ID]
Below is my query . I take socail sercurity no from Employee table and match it with child_excel table. Using that I get Employee ID and matching that with EmployeeCh table (which has employee ID). The employee has 2 child's so when I put the gender clause I get 4 records 2 for each child with different (i.e Male, Female) for each of the child's. I want only 2 rows for child 1 for each child with their respective genders.
SELECT distinct
[SSN],
empch2.GenderID,
gen.Name1
FROM [child_excel] as t
INNER JOIN Employee as empch on t.SSN = empch.SocialSecurityNo
INNER JOIN EmployeeCh as empch2 on empch.ID = empch2.EmployeeID
INNER JOIN Gender as gen on empch2.GenderID = gen.ID
I am getting O/p as
12345 1 Male
12345 2 Female
99999 1 Male
99999 2 Female
Expected output is
12345 1 Male
99999 2 Female
But when I add First Name in the join it gives proper output. I dnt want to use first Name
SELECT distinct
[SSN],
empch2.GenderID,
gen.Name1
FROM [child_excel] as t
INNER JOIN Employee as empch on t.SSN = empch.SocialSecurityNo
INNER JOIN EmployeeCh as empch2 on empch.ID = empch2.EmployeeID and t.First_Name= empch2.FirstName
INNER JOIN Gender as gen on empch2.GenderID = gen.ID
Use ROW_NUMBER ()
Select * from (
SELECT distinct
[SSN],
empch2.GenderID,
gen.Name1,
ROW_NUMBER()OVER(PARTITION BY [SSN] ORDER BY empch2.GenderID)RN
FROM [child_excel] as t
INNER JOIN Employee as empch on t.SSN = empch.SocialSecurityNo
INNER JOIN EmployeeCh as empch2 on empch.ID = empch2.EmployeeID and t.First_Name= empch2.FirstName
INNER JOIN Gender as gen on empch2.GenderID = gen.ID )T
WHERE T.RN = 1
I want to select some values from three tables with aggregate function but without duplicates in one of the columns, for example:
select t3.ValueDesc as FeatureType,
count(t2.Strategic) as TotalCount
,t2.RequestID,t1.StoryID --these are not needed, but put for better vision
from tblRequests t2
left outer join (select * from tblAgileMultiDD where Type=18) t3
on t3.FormulaValue = t2.Strategic
left outer join tblAgileStory t1
on t1.Feature = t2.RequestID
where t2.RequestID > 0
and t1.DemoStatus = 1
group by t3.ValueDesc
,t2.RequestID, t1.StoryID --these are not needed but put for better vision
order by t3.ValueDesc
And then it returns me something like this:
FeatureType TotalCount RequestID StoryID
Protect Base 1 311 1629
Protect Base 1 311 1630
Protect Base 1 312 1631
Protect Base 1 312 1637
New Market 1 313 1640
New Market 1 313 1645
And if I comment out lines with ",t2.RequestID, t1.StoryID", it gives me the result:
FeatureType TotalCount
Protect Base 4
New Market 2
So, for each unique combination of RequestID and StoryID it returns new row. How to make it return new row only for each unique RequestID regardless to StoryID?
So I want this query to result like this:
FeatureType TotalCount
Protect Base 2 (for RequestID = 311, 312)
New Market 1 (for RequestID = 313)
Putting word "distinct" at the beginning doesn't take effect on it.
Can you help me with this?
select distinct FeatureType,TotalCount from (
select t3.ValueDesc as FeatureType,
count(t2.Strategic) as TotalCount
,t2.RequestID
-- ,t1.StoryID --these are not needed, but put for better vision
from tblRequests t2
left outer join (select * from tblAgileMultiDD where Type=18) t3
on t3.FormulaValue = t2.Strategic
left outer join tblAgileStory t1
on t1.Feature = t2.RequestID
where t2.RequestID > 0
and t1.DemoStatus = 1
group by t3.ValueDesc
,t2.RequestID
-- , t1.StoryID --these are not needed but put for better vision
) as T
order by t3.ValueDesc
could you try this.
I have the following issue :
table # 1 structure :
Requests table for example have 2 columns :
Request_ID Branch_Name
1 xx
2 yy
3 xx
4 xx
5 yy
The second table : Requests_Items for example have the following columns
Request_ID Price
1 100
1 30
1 450
2 10
2 18
So i want my result set to be like :
Branch Name Num_of_Requests Total_Price
xx 3 580
Can you please help
select r.Branch_Name,
count(r.request_id) as Num_of_Requests,
sum(i.price) as Total_Price
from Requests r
left join Requests_Items i on i.Request_ID = r.Request_ID
group by r.Branch_Name
jurgen d was almost there
select r.Request_Id, r.Branch_Name,
COUNT(i.Price) as [Number of Requests],
SUM(i.Price) as [Total]
from Requests r
left join Requests_Items i
on r.Request_Id = i.Request_Id
group by r.Request_Id, r.Branch_Name
select r.Branch_Name, COUNT(ri.Request_ID) as Num_of_Requests, SUM(ri.Price) as Total_Price
from dbo.Requests r
left join dbo.Requests_Items ri
on r.Request_ID = ri.Request_ID
group by r.Branch_Name
Let this is my [Employees] Table
Here is my Dept table
I want the output like this using join and group by
So here is the Query for this-
