I want to check the column mr.name, if mr.name is null then i have to replace mr.name as mr.ticket_no. How? Can use if else or case?
select ROW_NUMBER() OVER(ORDER BY mr_user) sl_no,* from (select
mr.name as mr_no,
coalesce(mr.user_id,0) as mr_user
from stock_production_lot lot
left join kg_grn grn on (grn.name = lot.grn_no)
left join kg_department_indent mr on (mr.name = grn.mr_no)
order by mr.user_id) main
where mr_user=65
When i use like this
case when mr.name is null then '' else mr.ticket_no = grn.mr_no as mr_no
it will throw an error
if mr.name = null means i have to replace mr.name = mr.ticket_no. I want to check the column mr.name, if mr.name is null then i have to replace mr.name as mr.ticket_no
You can use coalesce() to replace null with anything:
select ROW_NUMBER() OVER(ORDER BY mr_user) sl_no,* from (select
coalesce(mr.name,mr.ticket_no) as mr_no,
coalesce(mr.user_id,0) as mr_user
from stock_production_lot lot
left join kg_grn grn on (grn.name = lot.grn_no)
left join kg_department_indent mr on (mr.name = grn.mr_no)
order by mr.user_id) main
where mr_user=65
But if you are comfortable with case when then use as below:
select ROW_NUMBER() OVER(ORDER BY mr_user) sl_no,* from (select
(case when mr.name is null then mr.ticket_no else mr.name end) as mr_no,
coalesce(mr.user_id,0) as mr_user
from stock_production_lot lot
left join kg_grn grn on (grn.name = lot.grn_no)
left join kg_department_indent mr on (mr.name = grn.mr_no)
order by mr.user_id) main
where mr_user=65

I have following SQL statement:

What I want.. If conversion_type = re-engagement then first row in CROSS JOIN LATERAL should be ('conversions'::text, report.conversions,'conversions'::text),.
If conversion_type = re-atribution then it should be ('installs'::text, report.conversions,'installs'::text). So I need smth like CASE - WHEN, but as far as i know, i can't use it inside cross join lateral values? I couldn't apply it. So I need to dynamically set metric_key in first row inside CROSS JOIN LATERAL. Is it possible?
The first entry in your VALUES list could simply be
VALUES (CASE WHEN conversion_type = 're-engagement'
THEN 'conversions'::text
ELSE 'installs'::text
END,
report.conversions,
CASE WHEN conversion_type = 're-engagement'
THEN 'conversions'::text

I have a requirement where I need to fetch the Dimension Key of Region table on basis of the following preference.
Fetch dimension key on basis of Zipcode of Physical address(PA)
If the first condition is not satisfied that fetch dimension key on basis of the Zip Code of the Mailing address
If the second condition is also not satisfied than fetch the dimension key on basis of the Parish Code of Physical address
Else fetch dimension key on basis of parish Code of Mailing address.
I am trying to use the below query but is giving multiple records since all left joins are getting evaluated. I want that it should not go on the second condition if the first condition is satisfied.
select REGION_DIM_SK, CASE_NUM
from (
select distinct COALESCE(RDIM.REGION_DIM_SK, RDIM1.REGION_DIM_SK, RDIM2.REGION_DIM_SK, RDIM3.REGION_DIM_SK) AS REGION_DIM_SK

left join rpt_dm_ee_prsnt.REGION_DIM RDIM1 ON dc.ZIP_CODE = RDIM1.ZIP_CODE AND RDIM1.REGION_EFF_END_DT IS NULL AND dc.addr_type_cd='MA' AND DC.EFF_END_DT IS NULL

Use multiple left joins. Your query is rather hard to follow -- it has other tables and references not described in the problem.
But the idea is:
select t.*,
coalesce(rpa.dim_key, rm.dim_key, rpap.dim_key, rmp.dim_key) as dim_key
from t left join
dim_region rpa
on t.physical_address_zipcode = rpa.zipcode left join
dim_region rm
on t.mailing_address_zipcode = rm.zipcode and
rpa.zipcode is null left join
dim_region rpap
on t.physical_addresss_parishcode = rpap.parishcode and
rm.zipcode is null left join
dim_region rmp
on t.physical_addresss_parishcode = rmp.parishcode and
rpap.zipcode is null
The trick is to put the conditions in CASE WHEN:
SELECT *
FROM table1 a
JOIN table2 b
ON CASE
WHEN a.code is not null and a.code = b.code THEN 1
WHEN a.type = b.type THEN 1
ELSE 0
END = 1
For your example you can reduce the code to just two joins, it can't be done in one as you are joining two different tables.
SELECT CASE WHEN RDIM.addres IS NULL THEN RDIM2.addres ELSE RDIM.addres
FROM rpt_dm_ee_intg.CASE_PERSON_ADDRESS dc
LEFT JOIN rpt_dm_ee_prsnt.REGION_DIM RDIM ON CASE
WHEN (dc.ZIP_CODE = RDIM.ZIP_CODE
AND RDIM.REGION_EFF_END_DT IS NULL
AND dc.addr_type_cd='PA'
AND dc.EFF_END_DT IS NULL) THEN 1
WHEN (dc.ZIP_CODE = RDIM1.ZIP_CODE
AND RDIM1.REGION_EFF_END_DT IS NULL
AND dc.addr_type_cd='MA'
AND DC.EFF_END_DT IS NULL) THEN 1
ELSE 0
END = 1
LEFT JOIN
(SELECT PARISH_CD,
min(REGION_DIM_SK) AS REGION_DIM_SK
FROM rpt_dm_ee_prsnt.REGION_DIM
WHERE REGION_EFF_END_DT IS NULL
GROUP BY PARISH_CD) RDIM2 ON CASE
WHEN (dc.addr_type_cd='PA'
AND dc.PARISH_CD = RDIM2.PARISH_CD
AND DC.EFF_END_DT IS NULL
AND RDIM.ZIP_CODE IS NULL) THEN 1
WHEN (dc.addr_type_cd='MA'
AND dc.PARISH_CD = RDIM3.PARISH_CD
AND DC.EFF_END_DT IS NULL
AND RDIM.ZIP_CODE IS NULL) THEN 1
ELSE 0
END = 1
edit
If you don't want to have nulls from RDIM2 table if RDIM1 zip code is present the logic could be easily extended to support that. You just need to add AND RDIM.ZIP_CODE IS NULL to CASE WHEN conditions.
I'm trying to group this case expression but unfortunately I'm getting an error.

ERROR:
Cannot use an aggregate or a subquery in an expression used for the group by list of a GROUP BY clause.
Is there anyway I can make this work?
I have a couple of suggestions. You are using select * in your case statements , but the columns referenced by '*' are not in your group by clause. To add them would be a bad way to fix the problem. Instead use ' select 1 ' and see what happens.
Second recommendation is to just not use the when exists rather use left join using sub queries and use those in your case statements.
So what I did is.
1. Removed the Case Statement on the Group By.
2. Modified the SubQueries on the Case Statement. Followed #Shiv Sidhu recommendation.
Thanks for everyone.
I am working in SQL server 2012. I have to write a sql statement where I first assign a value to [Pay_Type], which is a non-existing column (not sure whether it can be called as variable or not) and based upon its value I want to use it in another case statement as shown below
SELECT sp.First_Name, [Pay_Type] = CASE WHEN NOT EXISTS(SELECT '1' FROM
PERSON_SALARY ps WHERE ps.PARTY_ID = sp.PARTY_ID and ps.END_DATE IS NULL)
THEN 'Hourly' ELSE 'Salary' END,
HOURLY_RATE = CASE WHEN [Pay_Type] = 'Hourly' THEN pj.HOURLY_RATE ELSE
'0.00' END
FROM SEC_PERSON sp
LEFT OUTER JOIN PERSON_JOB pj ON sp.PERSON_ID = pj.PERSON_ID
WHERE sp.END_DATE IS NOT NULL
But I am getting "Invalid column name 'Pay_Type' " error.
Column aliases cannot be re-used in the same SELECT where they are define. The typical answer is to use a subquery or CTE. I also like using a lateral join:
SELECT sp.First_Name, s.Pay_Type,
HOURLY_RATE = (CASE WHEN s.Pay_Type = 'Hourly' THEN pj.HOURLY_RATE ELSE
'0.00' END)
FROM SEC_PERSON sp LEFT OUTER JOIN
PERSON_JOB pj
ON sp.PERSON_ID = pj.PERSON_ID OUTER APPLY
(SELECT (CASE WHEN NOT EXISTS (SELECT 1
FROM PERSON_SALARY ps
WHERE ps.PARTY_ID = sp.PARTY_ID and ps.END_DATE IS NULL
)
THEN 'Hourly' ELSE 'Salary'
END) as PayType
) s
WHERE sp.END_DATE IS NOT NULL
I am VERY new to SQL and self taught. I have two SQL that I stuggled through but got working. Now I need to combine them into one and I'm lost.
SELECT
s.lastfirst,
s.student_number,
SUM(tr.howmany)
FROM
students s
JOIN
truancies tr ON s.id = tr.studentid
WHERE
s.enroll_status = 0 AND
s.schoolid = ~(curschoolid)
GROUP BY
s.lastfirst, s.student_number
HAVING
SUM(tr.howmany) > 0
ORDER BY
s.lastfirst
And this table:
SELECT
S.DCID as DCID,
S.LASTFIRST as LASTFIRST,
S.STUDENT_NUMBER as STUDENT_NUMBER,
S2.FC_SRVC_HRS_DUE as FC_SRVC_HRS_DUE,
CASE
WHEN S2.FC_SRVC_HRS_COMPLETED IS NULL
THEN '0'
ELSE S2.FC_SRVC_HRS_COMPLETED
END AS FC_SRVC_HRS_COMPLETED,
S2.FC_SRVC_HRS_BUYOUT as FC_SRVC_HRS_BUYOUT,
CASE
WHEN S2.FC_SRVC_HRS_COMPLETED IS NULL
THEN S2.FC_SRVC_HRS_DUE * S2.FC_SRVC_HRS_BUYOUT
ELSE ((S2.FC_SRVC_HRS_DUE - S2.FC_SRVC_HRS_COMPLETED) * S2.FC_SRVC_HRS_BUYOUT)
END as Balance_Due
FROM
STUDENTS S, U_STUDENTSUSERFIELDS S2
WHERE
S.DCID = S2.STUDENTSDCID AND
s.enroll_status = 0 AND
s.schoolid = ~(curschoolid) AND
(((S2.FC_SRVC_HRS_DUE - S2.FC_SRVC_HRS_COMPLETED) * S2.FC_SRVC_HRS_BUYOUT) > 0 OR
((S2.FC_SRVC_HRS_DUE - S2.FC_SRVC_HRS_COMPLETED) * S2.FC_SRVC_HRS_BUYOUT) IS NULL) AND
S2.FC_SRVC_HRS_DUE >.1
ORDER BY
s.lastfirst
What I am really looking for are the totals of both of these. I want the SUM(tr.howmany) from the first table and the balance due of the second BUT I need the filters that are in there. This would be sorted by student. I hope I am making sense. Any assistance would be appreciated.
You can join together 2 separate SQL select statements:
Eg:
Select A.id, A.value, B.value
From (select id, count(*) as value from TableA ...) AS A
join (select id, sum(field) as value from TableB ...) AS B
on A.id = B.id
order by A.id
As long as you have a common field to join on this would work. In your case the student_number looks like a good candidate. You will have to do the ordering outside of your subqueries.
