I am using SQL Server. I have the below table (marked yellow). I am in a situation to generate the output (marked green) like this.
Conditions to use in the query:
When cal_wk is 1 then target_hrs value should take from cal_wk 2
When target_hrs is empty then target_hrs should be maximum of the result
I am trying the case statement like
select
r.hour_val,
case
when us.calwk = 1
then 2
else us.calwk
end as cal_wk,
hrswk as target_hrs, u.uid
from
table1 us
inner join
users u on u.username = us.username
inner join
table2 r on u.uid = r.uid
where
us.yr = 2016
and u.uid = 2643
and r.cur_month = 7
and r.week_val = us.calwk
order by
us.calwk
This is just changing cal_wk value not target_hrs.
Could any one write a query to generate the expected_target_hrs?
Thanks in advance for your support
Try
Select
Case when calwk = 1 then wk2_max
When calwk = 0 then max
Else target_hrs end as expected_target_hours
From [table name]
Inner join
(Select max(case when calwk = 2 then target_hrs else 0 end) as wk2_max,
Max(target_hrs) as max
From [table name])
On 1 = 1
Following your update to the question, you will need to replace [table name] with that join.

Two SQL LEFT JOINS produce incorrect result

Closed 9 months ago.
I may have messed up the joins or there may be another way of writing what I am trying to achieve.
My current query is this:
SELECT
i.SKI_NAME AS Description,
l.SKV_QUANTITY_IN_STOCK AS Qty,
SUM(CASE WHEN ad.AVN_STATUS = 'D' THEN li.AVL_QUANTITY ELSE '0' END) AS AdviceQty,
SUM(CASE WHEN con.HCT_STATUS = 'D' THEN item.HIT_QUANTITY ELSE '0' END) AS HireQty
FROM
TH_STOCK_LEVELS l
LEFT JOIN TH_STOCK_ITEMS i ON l.SKV_STOCK_NUMBER = i.SKI_STOCK_NUMBER
LEFT JOIN TH_ADVICE_NOTE_LINES li ON i.SKI_NAME = li.AVL_DESCRIPTION
LEFT JOIN TH_HIRE_ITEMS Item ON li.AVL_DESCRIPTION = Item.HIT_DESCRIPTION
LEFT JOIN TH_ADVICE_NOTES ad ON ad.AVN_ID = li.AVL_NOTE_NUMBER
LEFT JOIN TH_HIRE_CONTRACTS con ON con.HCT_CONTRACT_NUMBER = Item.HIT_CONTRACT_NUMBER
WHERE
l.SKV_DEPOT_ID = 7
GROUP BY i.SKI_NAME, l.SKV_QUANTITY_IN_STOCK;
This displays the following output:
Description
Qty
AdviceQty
HireQty
Some Item
2
400
100
Some Item
0
100
0
Which is incorrect, as it seems to be totalling all previous Advice's and Hire's and not just the ones with Status 'D'.
If I do the following to the query (comment some lines out):
SELECT
i.SKI_NAME AS Description,
l.SKV_QUANTITY_IN_STOCK AS Qty,
SUM(CASE WHEN ad.AVN_STATUS = 'D' THEN li.AVL_QUANTITY ELSE '0' END) AS AdviceQty
--SUM(CASE WHEN con.HCT_STATUS = 'D' THEN item.HIT_QUANTITY ELSE '0' END) AS HireQty
FROM
TH_STOCK_LEVELS l
LEFT JOIN TH_STOCK_ITEMS i ON l.SKV_STOCK_NUMBER = i.SKI_STOCK_NUMBER
LEFT JOIN TH_ADVICE_NOTE_LINES li ON i.SKI_NAME = li.AVL_DESCRIPTION
--LEFT JOIN TH_HIRE_ITEMS Item ON li.AVL_DESCRIPTION = Item.HIT_DESCRIPTION
LEFT JOIN TH_ADVICE_NOTES ad ON ad.AVN_ID = li.AVL_NOTE_NUMBER
--LEFT JOIN TH_HIRE_CONTRACTS con ON con.HCT_CONTRACT_NUMBER = Item.HIT_CONTRACT_NUMBER
WHERE
l.SKV_DEPOT_ID = 7
GROUP BY i.SKI_NAME, l.SKV_QUANTITY_IN_STOCK;
The output is correct, although I am now missing a column due to the comments. This also works if I comment out the Advice tables, the HireQty column would be correct.
Description
Qty
AdviceQty
Some Item
2
10
Some Item
0
0
How do I get this to display the correct data for both AdviceQty & HireQty without having to do them separately?
Sometimes, CASE statement doesn't work. You can try with IFs and see if it is working.
SELECT
i.SKI_NAME AS Description,
l.SKV_QUANTITY_IN_STOCK AS Qty, SUM(IF(ad.AVN_STATUS='D',li.AVL_QUANTITY,0)) AS AdviceQty, SUM(IF(con.HCT_STATUS='D',item.HIT_QUANTITY,0)) AS HireQty
FROM
TH_STOCK_LEVELS l
LEFT JOIN TH_STOCK_ITEMS i ON l.SKV_STOCK_NUMBER = i.SKI_STOCK_NUMBER LEFT JOIN TH_ADVICE_NOTE_LINES li ON i.SKI_NAME = li.AVL_DESCRIPTION LEFT JOIN TH_HIRE_ITEMS Item ON li.AVL_DESCRIPTION
= Item.HIT_DESCRIPTION LEFT JOIN TH_ADVICE_NOTES ad ON ad.AVN_ID = li.AVL_NOTE_NUMBER LEFT JOIN TH_HIRE_CONTRACTS con ON con.HCT_CONTRACT_NUMBER = Item.HIT_CONTRACT_NUMBER
WHERE
l.SKV_DEPOT_ID = 7
GROUP BY i.SKI_NAME, l.SKV_QUANTITY_IN_STOCK;
How do i achieve achieve all this records under one row since every employee has one of each NHIF, NSSF and KRA number?
Below is the query i used but the all appear separate rows.
SELECT DISTINCT
hrmemployeehdr.employeeslno,
hrmemployeehdr.employeecode,
hrmemployeehdr.employeefirstname,
hrmemployeehdr.employeemiddlename,
hrmemployeehdr.employeelastname,
hrmDesignationHdr.DesignationName,
hrmemployeehdr.DateOfBirth,
hrmemployeehdr.DateOfJoin,
hlocationhdr.locationname,
hrmEmployeeIdentityDtl.IDProofReferenceNo AS [National ID],
(CASE
WHEN hrmEmployeeDeductionSettingsDtl.DeductionCode = 1 THEN hrmEmployeeDeductionSettingsDtl.EmployeeRegID
ELSE ''
END) AS NHIF,
(CASE
WHEN hrmEmployeeDeductionSettingsDtl.DeductionCode = 2 THEN hrmEmployeeDeductionSettingsDtl.EmployeeRegID
ELSE ''
END) AS NSSF,
(CASE
WHEN hrmEmployeeDeductionSettingsDtl.DeductionCode = 3 THEN hrmEmployeeDeductionSettingsDtl.EmployeeRegID
ELSE ''
END) AS KRA,
hrmemployeestatusdtl.Email AS [Employee Email],
huser.email AS [User Account Email],
hrmEmployeeGradeHdr.GradeName,
hDepartment.DepartmentName
FROM hrmemployeehdr
JOIN hrmemployeestatusdtl ON hrmemployeestatusdtl.employeeslno = hrmemployeehdr.employeeslno
JOIN hdivision ON hdivision.divisioncode = hrmemployeestatusdtl.divisioncode
JOIN hlocationhdr ON hlocationhdr.locationcode = hrmemployeestatusdtl.workinglocationcode
JOIN hDepartment ON hDepartment.DepartmentCode = hrmemployeestatusdtl.DepartmentCode
JOIN hrmDesignationHdr ON hrmDesignationHdr.DesignationCode = hrmemployeestatusdtl.DesignationCode
JOIN hrmEmployeeCategoryHdr ON hrmEmployeeCategoryHdr.CategoryCode = hrmemployeestatusdtl.CategoryCode
JOIN hrmEmployeeGradeHdr ON hrmEmployeeGradeHdr.GradeCode = hrmemployeestatusdtl.GradeCode
LEFT JOIN huser ON huser.employeeslno = hrmemployeehdr.employeeslno
JOIN hMasterValue ON hMasterValue.MasterValueID = hrmemployeestatusdtl.MasterValue_EmploymentStatusID
JOIN hrmEmployeeIdentityDtl ON hrmEmployeeIdentityDtl.EmployeeSlno = hrmemployeehdr.EmployeeSlno
INNER JOIN hMasterValue a ON a.MasterValueID = hrmEmployeeIdentityDtl.MasterValue_IDProofTypeID
INNER JOIN hrmEmployeeDeductionSettingsDtl ON hrmEmployeeDeductionSettingsDtl.EmployeeSlno = hrmemployeehdr.EmployeeSlno
LEFT JOIN hrmDeductionHdr ON hrmDeductionHdr.DeductionCode = hrmEmployeeDeductionSettingsDtl.DeductionCode
WHERE hrmemployeestatusdtl.employeeslno NOT IN (SELECT hrmemploymentstoppageandtermination.employeeslno
FROM hrmemploymentstoppageandtermination)
AND hrmEmployeeIdentityDtl.MasterValue_IDProofTypeID = 2741005
--and hrmemployeestatusdtl.email = huser.email
--and huser.isemployee = 1
-- select * from huser
ORDER BY employeefirstname ASC;
Use conditional aggregation on the detail table to condense all those rows into one for each employee. Something like:
with edet as (select employeeslno,
max(CASE DeductionCode when 1 THEN EmployeeRegID ELSE '' END) AS NHIF,
max(CASE DeductionCode when 2 THEN EmployeeRegID ELSE '' END) AS NSSF,
max(CASE DeductionCode when 3 THEN EmployeeRegID ELSE '' END) AS KRA
from dbo.hrmEmployeeDeductionSettingsDtl
group by employeeslno)
select emp.employeeslno, ...,
edet.NHIF, edet.NSSF, edet.KRA, ...
from dbo.hrmemployeehdr as emp
inner join edet on emp.employeeslno = edet.employeeslno
...
order by ...
;
Notice the formatting changes that HELP everyone read and understand the code as well as the good habits of using aliases, schema-qualified table names, statement terminator, etc. As already mentioned, the other joins might be contributing to the problem - but this addresses the 1:3 relationship between the header and detail table.
I want to get fields from 2 different tables . The last field candidate_score_id has a many to one relationship. So how should I join the below 2 queries
1) To get candidate_score_id from the candidate_score table.
select candidate_score_id from candidate_score a where
a.assessment_id = NEW.assessment_id and
a.candidate_id = NEW.candidate_id and
a.attempt_Count = NEW.attempt_count;
2) To insert different fields in to the candidate_score_details table. The field in this table should be obtained by query above.
insert into candidate_score_details(candidate_score_details_id, candidate_id, assessment_id, attempt_count, score_type, score_tag,correct, candidate_score_id)
select uuid();
select a.candidate_id, a.assessment_id,a.attempt_count,"BY-COMPLEXITY",
case c.complexity
when 1 then "HIGH"
when 2 then "MEDIUM"
when 3 then "LOW"
end, count(*) from candidate_answer a, answer_key b, question_meta_data c where a.candidate_id = NEW.candidate_id and
a.assessment_id = NEW.assessment_id and
a.attempt_count = NEW.attempt_count and
a.assessment_id = b.assessment_id and
a.question_id = b.question_number and
a.response = b.answer and
a.question_id = c.question_number
group by a.candidate_id, a.assessment_id, a.attempt_count, c.complexity;
Just looking at the SQL joining aspect of your question, you'll need to specify the table I THINK you're aliasing a 2nd table with the "NEW" reference. If that's the case, then the query would be (replacing "OTHER_TABLE_NAME" with the name of the 2nd table:
select a.candidate_score_id
from candidate_score a
left join OTHER_TABLE_NAME new on
and a.assessment_id = NEW.assessment_id
and a.candidate_id = NEW.candidate_id
and a.attempt_Count = NEW.attempt_count
Seems that Query 1 has the same 3 criteria on the "candidate_score" table as for the "candidate_answer" table in Query 2.
So how about adding a LEFT JOIN of "candidate_score" to "candidate_answer" on those 3 fields?
For example:
INSERT INTO candidate_score_details
(
candidate_score_details_id,
candidate_id,
assessment_id,
attempt_count,
score_type,
score_tag,
correct,
candidate_score_id
)
SELECT
uuid(),
answer.candidate_id,
answer.assessment_id,
answer.attempt_count,
'BY-COMPLEXITY' AS score_type,
(CASE meta.complexity
WHEN 1 THEN 'HIGH'
WHEN 2 THEN 'MEDIUM'
WHEN 3 THEN 'LOW'
END) AS score_tag,
COUNT(*) AS correct,
MAX(score.candidate_score_id) AS max_candidate_score_id
FROM candidate_answer AS answer
JOIN answer_key AS akey
ON (akey.assessment_id = answer.assessment_id AND akey.question_number = answer.question_id AND akey.answer = answer.response)
LEFT JOIN candidate_score AS score
ON (score.candidate_id = answer.candidate_id AND score.assessment_id = answer.assessment_id AND score.attempt_count = answer.attempt_count)
LEFT JOIN question_meta_data AS meta
ON meta.question_number = answer.question_id
WHERE answer.candidate_id = NEW.candidate_id
AND answer.assessment_id = NEW.assessment_id
AND answer.attempt_count = NEW.attempt_count
GROUP BY answer.candidate_id, answer.assessment_id, answer.attempt_count, meta.complexity;
OK, I've looked this up and tried a number of solutions, but can't get it to work. I'm a bit of a novice. Here's my original query - how can I get it to return 0 for an account when there are no results in the student table?
SELECT a.NAME
,count(s.student_sid)
FROM account a
JOIN inst i ON a.inst_sid = i.root_inst_sid
JOIN inst_year iy ON i.inst_sid = iy.inst_sid
JOIN student s ON iy.inst_year_sid = s.inst_year_sid
WHERE s.demo = 0
AND s.STATE = 1
AND i.STATE = 1
AND iy.year_sid = 16
AND a.account_sid IN (
20187987
,20188576
,20188755
,52317128
,20189249
)
GROUP BY a.NAME;
Use an outer join, moving the condition on that table into the join:
select a.name, count(s.student_sid)
from account a
join inst i on a.inst_sid = i.root_inst_sid
join inst_year iy on i.inst_sid = iy.inst_sid
left join student s on iy.inst_year_sid = s.inst_year_sid
and s.demo = 0
and s.state = 1
where i.state = 1
and iy.year_sid = 16
and a.account_sid in (20187987, 20188576, 20188755, 52317128, 20189249)
group by a.name;
count() does not count null values, which s.student_sid will be if no rows join from student.
You need to LEFT JOIN and then SUM() over the group where s.student_sid is not null:
select
a.name,
sum(case when s.student_sid is null then 0 else 1 end) as student_count
from account a
join inst i on a.inst_sid = i.root_inst_sid
join inst_year iy on i.inst_sid = iy.inst_sid
left join student s
on iy.inst_year_sid = s.inst_year_sid
and s.demo = 0
and s.state = 1
where i.state = 1
and iy.year_sid = 16
and a.account_sid in (20187987, 20188576, 20188755, 52317128, 20189249)
group by a.name;
This is assuming that all of the fields in the student table that you are filtering on are optional. If you don't want to enforce removal of records where, say, s.state does not equal 1, then you need to move the s.state=1 predicate into the WHERE clauses.
If, for some reason, you are getting duplicate student IDs and students are being counted twice, then you can change the aggregate function to this:
count(distinct s.student_id) as student_count
...which is safe to do as count(distinct ...) ignores null values.

the questionresultid and sectionresultid are returning multiple values
how can i fix the joins so that it doesnt return multiple values?
i have it drilled down to a date and a person so that it should only return one row of results( but that obviously didnt work)
not sure what other data i can provide
update
i think it has to do with joins
inner join aqm.dbo.sectionresult scr on scr.sectionid = sec.sectionid
inner join aqm.dbo.questionresult qr on qr.sectionresultid = scr.sectionresultid
as those are the ones returning multiple results.
just dont know how to fix it
First, neither aqm.dbo.questiontype nor aqm.dbo.questionoption are used in your return fields or your where clause so get rid of them if they aren't required.
Second, you are OUTER JOINing on the aqm.dbo.review, but the reviewstatusid and reviewdate are required in the WHERE clause - so this should probably be an INNER JOIN.
Last, best way to debug issues like this is to comment out the COUNT statements and the GROUP BY clause - and see what raw data is being returned.
