I have a typical situation.
my table has four column. (id, user, col2, status)
I want to write a query which gives me the results of col2. But it has a column status which has (0/1). So I want only col2 data which has 0 status + a user's all data (0/1).
id user col2 status
1 sam aa 1
2 sam bb 0
3 sam cc 1
4 max dd 0
5 max dd 1
6 max ee 1
7 jam ff 0
8 jam gg 1
My result should be like. I want sam's all result + other's only 0 status result.
id user col2 status
1 sam aa 1
2 sam bb 0
3 sam cc 1
4 max dd 0
7 jam ff 0
How about
SELECT * FROM yourTable WHERE user = "sam" OR status = 0;
?
your where condition would be:
where (user = 'sam' or status = 0)
select * from the_table where user = 'sam' or status = 0 order by id
select *
from yourtable as t
where t.user = "sam"
or t.status = 0
SELECT *
FROM YOUR_TABLE
WHERE user = 'sam' OR
status = 0
We use OR in the WHERE clause so that it will be true for all of sam's rows and for all other rows which have status as 0

I had two tables as below:

update_from_id
sw_ref_number
raised_by_user_id
raised_date

My query is:
select req.request_id,
req.sw_ref_number,
reqDet.[value] ,
reqDet.input_id
FROM SOF.tblSOFRequest req
left join SOF.tblSOFRequestDetails reqDet
on req.request_id = reqDet.request_id
where reqDet.input_id = 1
or reqDet.input_id = 2
And after that my result is:
request_id
sw_ref_number
value
input_id

I want a result as:
request_id
sw_ref_number
epi_db_no
manuf_no
1

00001

00002
Here input_id = 1 means epi_db_no and input_id = 2 means manuf_no.
How can I get this?
Thanks
You can do it using self-join like the following query.
SELECT req.request_id
,req.sw_ref_number
,reqDet.[value] AS epi_db_no
,reqDet2.[value] AS manuf_no
FROM SOF.tblSOFRequest req
LEFT JOIN SOF.tblSOFRequestDetails reqDet ON req.request_id = reqDet.request_id
LEFT JOIN SOF.tblSOFRequestDetails reqDet2 ON reqDet.request_id = reqDet2.request_id
AND reqDet2.input_id = 2
WHERE reqDet.input_id = 1
This seems like a simple pivot. I use conditional aggregation here:
SELECT req.request_id,
req.sw_ref_number,
MAX(CASE reqDet.input_id WHEN 1 THEN reqDet.[value] END) AS epi_db_no,
MAX(CASE reqDet.input_id WHEN 2 THEN reqDet.[value] END) AS manuf_no
FROM SOF.tblSOFRequest req
JOIN SOF.tblSOFRequestDetails reqDet ON req.request_id = reqDet.request_id
WHERE reqDet.input_id IN (1,2)
GROUP BY req.request_id,
req.sw_ref_number;
I must do a query where I select those groups, given by de concatenation between sample and serial that could be defined as household, where at least one in the variable bplcountry = 1
sample serial bplcountry
1 1 2
1 1 1
1 3 2
2 1 2
2 2 2
2 3 2
3 1 2
3 3 2
3 3 1
I have made some research but I'm very amateur on SQL. I get some hint like this:
SELECT *
FROM latinCensus
GROUP BY sample AND serial
HAVING COUNT(bplcountry NOT IN ('1') OR NULL) = 0
Also I got some idea in this way
SELECT *
FROM latinCensus
GROUP BY CONCAT(sample,serial)
HAVING COUNT(bplcountry NOT IN ('1') OR NULL) = 0
I would expect something like this:
sample serial bplcountry
1 1 2
1 1 1
3 3 2
3 3 1
I will appreciate your help!
You want the pairs where bplcountry is 1. You can use window functions:
select lc.*
from (select lc.*,
sum(case when bplcountry = 1 then 1 else 0 end) over (partition by sample, serial) as cnt_1
from latincensus lc
) lc
where cnt_1 > 0;
Or use exists:
select lc.*
from latincensus lc
where exists (select 1
from latincensus lc2
where lc2.sample = lc.sample and lc2.serial = lc.serial and
lc2.bplcountry = 1
);
You haven't tagged your db, but something along these lines should work (can also be expressed using joins)
select sample, serial, bplcountry
from t
where (sample,serial) in (select sample,serial
from t
where bplcountry=1);
SubjectMaster

4 2 2 02/20/2020 60
5 3 0 Null Null
6 4 3 02/18/2020 56
These are my sample tables.
I want to show records from log table of zero as well as all assigned subject of user 1
Suppose user 1 has 2 subject 1 and 3.
Show records from logs where subjectid comes in 0 as well as 1,3
Required Output :
Logs
Id Userid SubjectId Examdate Percentage
1 1 1 02/20/2020 50
2 1 0 Null Null
3 2 1 02/20/2020 70
4 3 0 Null Null
5 4 3 02/18/2020 56
Query :
select * from logs where rdatetime >= '' and subjectid in (select id from subjectmaster where userid = 1)
'Or' did not work.It was giving wrong output.How to handle it.
If I understand correctly, you want a correlated subquery and condition like this:
select l.*
from logs l
where l.subjectid = 0 or
exists (select 1
from subjectmaster sm
where sm.userid = l.userid and
sm.subjectid = l.subjectid
);
You can do left join :
select l.*
from logs l left join
subjectmaster sm
on sm.userid = l.userid and
sm.subjectid = l.subjectid
where not (l.subjectid <> 0 and sm.subjectid is null);
This query will give you the desired result:
select *
from logs l
where subjectid = 0
OR
subjectid IN (select subjectid
from UserSubjectAssociation
where Userid = 1)
I have a select query that ends up with results like:
ID COMPLIANT
------------------
10 0
12 0
29 0
29 1
43 1
44 1
44 0
How can I get results without these duplicate ID rows, on the condition that if an ID has already been marked as COMPLIANT once (a 1 instead of a 0), the duplicate rows with COMPLIANT=0 do not appear? I'd want:
ID COMPLIANT
------------------
10 0
12 0
29 1
43 1
44 1
How about aggregation?
select id, max(complaint) as complaint
from t
group by id;
This returns one row per id. If you can have multiple complaints -- and you want all of those -- than an alternative is:
select id, complaint
from t
where complaint = 1
union all
select id, complaint
from t
where not exists (select 1 from t t2 where t2.id = t.id and t2.complaint = 1);
this will work:
select id, max(complaint)
from tablename
group by id;
I have following table structure
ID Status1 status 2 status 3
A1 1 0 1
A1 1 1 0
A2 1 0 0
A3 0 1 1
I want to collect it as one record like this (only 1's count for each column)
A1 2 1 1
A2 1 1 0
A3 0 1 1
I have tried using pivot but actually not the one am getting it correctly.
Please give some thought.
Hope you looking for this
