All three table contains 'semester' and 'department' column
SELECT DISTINCT
test_name,
fname,
lname,
rno
FROM exam_attempted_list
INNER JOIN stud_test ON
exam_attempted_list.student_id = stud_test.student_id
INNER JOIN stud_reg ON
exam_attempted_list.student_id = stud_reg.student_id WHERE semester='2nd' AND department='cse'
Use the following format, i.e, there were some statements which were repeating in your query, missing aliases in statements:
SELECT DISTINCT exam_attempted_list.test_name ,exam_attempted_list.fname,
exam_attempted_list.lname , exam_attempted_list.rno
FROM exam_attempted_list
INNER JOIN stud_test
ON exam_attempted_list.student_id = stud_test.student_id
INNER JOIN stud_reg
ON exam_attempted_list.student_id = stud_reg.student_id
WHERE semester='2nd' AND department='cse'
Use table aliase like exam_attempted_list.semester='2nd'
SELECT DISTINCT test_name ,fname, lname ,rno
FROM
exam_attempted_list
INNER JOIN stud_test ON exam_attempted_list.student_id = stud_test.student_id
INNER JOIN stud_reg ON exam_attempted_list.student_id = stud_reg.student_id
WHERE exam_attempted_list.semester='2nd' AND exam_attempted_list.department='cse';
SELECT DISTINCT eal.test_name , eal.fname, eal.lname , eal.rno
FROM exam_attempted_list AS eal
INNER JOIN stud_test AS st ON eal.student_id = st.student_id
INNER JOIN stud_reg AS sr ON eal.student_id = sr.student_id
WHERE eal.semester='2nd' AND eal.department='cse'
Replace eal with either st or sr depending on where you want the data from.

I have data in a temporary table and I need to update this with the new data found with other tables using joins. How can I change the second select to an update statement?
Can you please suggest how to do this?
Thank you

Your question is similar to this: Update records in table from CTE
Your can try the following method
with cte as(
SELECT
t.str_psn , t.str_esn, t.id_smartcard, t.id_customer, t.str_statusdesc,
t.str_title, subpax.datAdded, tok.str_token_desc, subpax.ultTokenType

INNER JOIN SmarTrack.dbo.TravelToken tt ON subpax.id_TravelToken = tt.id_traveltoken
INNER JOIN SmarTrack.dbo.TokenType tok on subpax.ultTokenType = tok.int2_tokentype
)
Update #temp
Set #temp.id_customer in (Select distinct id_customer From cte)
This SQL query needs to be done in ACCESS.
I am trying to do a subquery on the total sales, but I want to link the sale to the province AND to product. The below query will work with one or the other: (po.product_name = allp.all_products) AND (p.province = allp.all_province); -- but it will no take both.
I will be including every month into this query, once I can figure out the subquery on with two criteria.
Select
p.province as [Province],
po.product_name as [Product],
all_price
FROM
(purchase_order po
INNER JOIN person p
on p.person_id = po.person_id)
left join
(
select
po1.product_name AS [all_products],
sum(pp1.price) AS [all_price],
p1.province AS [all_province]
from (purchase_order po1
INNER JOIN product pp1
on po1.product_name = pp1.product_name)
INNER JOIN person p1
on po1.person_id = p1.person_id
group by po1.product_name, pp1.price, p1.province
)
as allp
on (po.product_name = allp.all_products) AND (p.province = allp.all_province);
Make the first select sql into a table by giving it an alias and join table 1 to table 2. I don't have your table structure or data to test it but I think this will lead you down the right path:
select table1.*, table2.*
from
(Select
p.province as [Province],
po.product_name as [Product]
--removed this ,all_price
FROM
(purchase_order po
INNER JOIN person p
on p.person_id = po.person_id) table1
left join
(
select
po1.product_name AS [all_products],
sum(pp1.price) AS [all_price],
p1.province AS [all_province]
from (purchase_order po1
INNER JOIN product pp1
on po1.product_name = pp1.product_name)
INNER JOIN person p1
on po1.person_id = p1.person_id
group by po1.product_name, pp1.price, p1.province --check your group by, I dont think you want pp1.price here if you want to aggregate
) as table2 --changed from allp
on (table1.product = table2.all_products) AND (table1.province = table2.all_province);
I have this query:
SELECT
a.account_uuid,
a.account_no,
a.account_group_uuid,
a.account_scope_uuid,
a.created_at,
a.deleted_at,
s.service_uuid,
s.status,
st.service_type,
(
SELECT
c.company
FROM companies c
WHERE a.company_owner_uuid = c.company_uuid
)
FROM
accounts a
LEFT JOIN
services s
ON a.account_uuid = s.account_uuid
LEFT JOIN
service_types st
ON s.service_type_uuid = st.service_type_uuid
WHERE
a.deleted_at IS NULL
ORDER BY
a.account_no
And I need to join and select multiple columns from a people table by way of a pivot table accounts_contacts that would have the account_uuid and a person_uuid. There are also is_primary and is_active columns on the accounts_contacts table and there will only be one primary at a time, so the end result would be a single first and last name. This is the idea of the query:
SELECT
p.first_name, p.last_name
FROM
people p
INNER JOIN
accounts_contacts ac
ON ac.account_uuid = a.account_uuid
AND ac.person_uuid = p.person_uuid
WHERE
ac.is_primary = true
AND ac.is_active = true
But not sure how to fit it into the above query. A subquery would only allow for one of the columns.
account_contacts is an "association" or "junction" table. It is not a pivot table.
The basic idea should be joins:
SELECT . . . ,
p.first_name, p.last_name
FROM accounts a LEFT JOIN
services s
ON a.account_uuid = s.account_uuid LEFT JOIN
service_types st
ON s.service_type_uuid = st.service_type_uuid LEFT JOIN
accounts_contacts ac
ON ac.account_uuid = a.account_uuid LEFT JOIN
people p
ON ac.person_uuid = p.person_uuid AND
ac.is_primary = true AND
ac.is_active = true
I've got the following SQL Statement:
select * from Leaves inner join LeaveDetails on Leaves.LeaveId= LeaveDetails.LeaveId
inner join Employee on Leaves.EmployeeCode = Employee.EmployeeCode
inner join LeaveType on Leaves.LeaveTypeId= LeaveType.LeaveTypeId
inner join LeaveStatus on Leaves.StatusId = LeaveStatus.StatusId
inner join Employee_organizationaldetails on Employee_organizationaldetails.EmployeeCode=Employee.EmployeeCode
where Leaves.LeaveId = 7295
Employee_organizationdetails contains another column called reporting officer which is a foreign key to the same Employee table. Now I need to get the name of the Employee.
How can I write the above query so that I can get the name of the reporting officer as another column without fetching executing the query
select (FirstName + ' ' + LastName) as name from Employee where EmployeeCode = ReportingTo
Here ReportingTo is the employee code. I need to join them vertically. Something similar to Union operator
You want to join back to another "copy" of the Employee table:
select *, (ro.FirstName + ' ' + LastName) as ReportingName
from Leaves inner join LeaveDetails on Leaves.LeaveId= LeaveDetails.LeaveId
inner join Employee on Leaves.EmployeeCode = Employee.EmployeeCode
inner join LeaveType on Leaves.LeaveTypeId= LeaveType.LeaveTypeId
inner join LeaveStatus on Leaves.StatusId = LeaveStatus.StatusId
inner join Employee_organizationaldetails on Employee_organizationaldetails.EmployeeCode=Employee.EmployeeCode left outer join
Employee ro
on ro.EmployeeCode = ReportingTo
where Leaves.LeaveId = 7295;
You probably don't want the * -- I assume it is just a shorthand for the question. It is better to list columns explicitly, especially because there are duplicate column names.
Possible this be helpful for you -
SELECT
*
, ReportingName = ro.FirstName + ' ' + LastName
FROM (
SELECT *
FROM dbo.Leaves l
WHERE l.LeaveId = 7295
) l
JOIN dbo.LeaveDetails ld ON l.LeaveId = ld.LeaveId
JOIN dbo.Employee e ON l.EmployeeCode = e.EmployeeCode
JOIN dbo.LeaveType lt ON l.LeaveTypeId = lt.LeaveTypeId
JOIN dbo.LeaveStatus ls ON l.StatusId = ls.StatusId
JOIN dbo.Employee_organizationaldetails e2 ON e2.EmployeeCode = e.EmployeeCode
LEFT JOIN dbo.Employee ro ON ro.EmployeeCode = ReportingTo
I have this query which returns qty in each of my branch. now the branch has two WH_subType as you see in the attached diagram i have attached. I want to sum the 2 subtype and show its available qty. how can i do it.
my select query is like this
SELECT
dbo.WarehouseType.name AS Section,
dbo.WarehouseSubType.name AS WH_Type,
dbo.WarehouseSubType1.name AS WH_SubType,
dbo.Branch.name AS Branch,
(dbo.WarehouseProductQuantity.actualQuantity - dbo.WarehouseProductQuantity.reservedQuantity) AS AvailQty,
dbo.WarehouseProductQuantity.tafsilId AS Tafsil,
dbo.Tafsil.description AS Product_Name
FROM
dbo.WarehouseSubType
INNER JOIN
dbo.WarehouseType
ON
(
dbo.WarehouseSubType.warehouseTypeId = dbo.WarehouseType.id)
INNER JOIN
dbo.WarehouseSubType1
ON
(
dbo.WarehouseSubType.id = dbo.WarehouseSubType1.warehouseSubTypeId)
INNER JOIN
dbo.Warehouse
ON
(
dbo.WarehouseSubType1.id = dbo.Warehouse.warehouseSubType1Id)
INNER JOIN
dbo.Branch
ON
(
dbo.Warehouse.branchId = dbo.Branch.id)
INNER JOIN
dbo.WarehouseProductQuantity
ON
(
dbo.Warehouse.id = dbo.WarehouseProductQuantity.warehouseId)
INNER JOIN
dbo.TafsilLink
ON
(
dbo.WarehouseProductQuantity.tafsilId = dbo.TafsilLink.sourceId)
INNER JOIN
dbo.Tafsil
ON
(
dbo.TafsilLink.targetId = dbo.Tafsil.id)
INNER JOIN
dbo.FinishProduct
ON
(
dbo.Tafsil.id = dbo.FinishProduct.tafsilId)
INNER JOIN
dbo.Supplier
ON
(
dbo.FinishProduct.supplierId = dbo.Supplier.tafsilId)
WHERE
WarehouseSubType1.warehouseSubTypeId IN (1,4)
group by dbo.WarehouseProductQuantity.tafsilId
Have you tried a group by
SELECT SubType, SUM(qty) AS QtySum
GROUP BY SubType
Every grouped by column should be in your select. Note: for every column you group by it further sub divides the data
Update based on OP comment:
If you want other columns you need to do something like
SELECT s.WH_SubType,s.AvailQty, t.other_cols
from
(SELECT
dbo.WarehouseSubType1.name AS WH_SubType,
sum(dbo.WarehouseProductQuantity.actualQuantity - dbo.WarehouseProductQuantity.reservedQuantity) AS AvailQty
FROM
table
GROUP BY
dbo.WarehouseSubType1.name) s
left join table t on t.dbo.WarehouseSubType1.name = s.WH_SubType;
For reference see this question: How do I use "group by" with three columns of data?
UPDATE 2:
SELECT
dbo.WarehouseType.name AS Section,
dbo.WarehouseSubType.name AS WH_Type,
dbo.WarehouseSubType1.name AS WH_SubType,
dbo.Branch.name AS Branch,
SumTable.AvailQty,
SumTable.Tafsil,
dbo.Tafsil.description AS Product_Name
FROM
dbo.WarehouseSubType
INNER JOIN
dbo.WarehouseType
ON
(
dbo.WarehouseSubType.warehouseTypeId = dbo.WarehouseType.id)
INNER JOIN
dbo.WarehouseSubType1
ON
(
dbo.WarehouseSubType.id = dbo.WarehouseSubType1.warehouseSubTypeId)
INNER JOIN
dbo.Warehouse
ON
(
dbo.WarehouseSubType1.id = dbo.Warehouse.warehouseSubType1Id)
INNER JOIN
dbo.Branch
ON
(
dbo.Warehouse.branchId = dbo.Branch.id)
INNER JOIN
dbo.WarehouseProductQuantity
ON
(
dbo.Warehouse.id = dbo.WarehouseProductQuantity.warehouseId)
INNER JOIN
dbo.TafsilLink
ON
(
dbo.WarehouseProductQuantity.tafsilId = dbo.TafsilLink.sourceId)
INNER JOIN
dbo.Tafsil
ON
(
dbo.TafsilLink.targetId = dbo.Tafsil.id)
INNER JOIN
dbo.FinishProduct
ON
(
dbo.Tafsil.id = dbo.FinishProduct.tafsilId)
LEFT JOIN (SELECT
sum(dbo.WarehouseProductQuantity.actualQuantity - dbo.WarehouseProductQuantity.reservedQuantity) AS AvailQty,
dbo.WarehouseProductQuantity.tafsilId AS Tafsil
FROM
dbo.WarehouseProductQuantity
group by dbo.WarehouseProductQuantity.tafsilId) SumTable on dbo.Tafsil.id = SumTable.Tafsil
WHERE
WarehouseSubType1.warehouseSubTypeId IN (1,4)
You need to do something like
SELECT SUM(AvailQty), ... FROM ... WHERE ... GROUP BY WH_SubType
