I have the following query where I unique records for patient_id, meaning patient_id should not be duplicate. Each time I try executing the query, seems like the DB hangs or it takes hours to execute, I'm not sure. I need my records to load quickly. Any quick resolution will be highly appreciated.
SELECT DISTINCT a.patient_id,
a.study_id,
a.procstep_id,
a.formdata_seq,
0,
(SELECT MAX(audit_id)
FROM audit_info
WHERE patient_id =a.patient_id
AND study_id = a.study_id
AND procstep_id = a.procstep_id
AND formdata_seq = a.formdata_seq
) AS data_session_id
FROM frm_rg_ps_rg a,
PATIENT_STUDY_STEP pss
WHERE ((SELECT COUNT(*)
FROM frm_rg_ps_rg b
WHERE a.patient_id = b.patient_id
AND a.formdata_seq = b.formdata_seq
AND a.psdate IS NOT NULL
AND b.psdate IS NOT NULL
AND a.psresult IS NOT NULL
AND b.psresult IS NOT NULL) = 1)
OR NOT EXISTS
(SELECT *
FROM frm_rg_ps_rg c
WHERE a.psdate IS NOT NULL
AND c.psdate IS NOT NULL
AND a.psresult IS NOT NULL
AND c.psresult IS NOT NULL
AND a.patient_id = c.patient_id
AND a.formdata_seq = c.formdata_seq
AND a.elemdata_seq! =c.elemdata_seq
AND a.psresult != c.psresult
AND ((SELECT (a.psdate - c.psdate) FROM dual)>=7
OR (SELECT (a.psdate - c.psdate) FROM dual) <=-7)
)
AND a.psresult IS NOT NULL
AND a.psdate IS NOT NULL;
For start, you have a cartesian product with PATIENT_STUDY_STEP (pss).
It is not connected to anything.
select *
from (select t.*
,count (*) over (partition by patient_id) as cnt
from frm_rg_ps_rg t
) t
where cnt = 1

I have lets say two terms term A (previous)and term B (current) , i need to check if pol_cancl_date is null or not in term A , there is a transaction_sequence_number , i need to see if the pol_cncl_date is existing in the greatest A.transaction_sequence_number and if greatest( A.transaction_sequence_number ) is the greated when compared to all B.transaction_sequence_number numbers , if it is then i would want to check for pol_cancl_dates's existence and apply a logic

this logic is still not giving me some results , one thing is that trans_seq_num doesn't necessarily have to be one less
Hello Stackoverflow community !
I got this code :
(SELECT COALESCE(id, 0) FROM members WHERE user_id = 1225282512438558720)
UNION ALL
(SELECT COALESCE(id, 0) FROM channels WHERE channel_id = 720694686028791971)
UNION ALL
(SELECT COALESCE(id, 0) FROM guilds WHERE guild_id = 831900150115991605);
Each statement could or not could return a value (because nothing corresponds to the WHERE Clause)
My problem is that if for example the first statement returns nothing then Postgres is going to return me this
coalesce
----------
6
1
but i want that Postgres returns me this :
coalesce
----------
NULL
6
1
How can i do that ?
This query returns nothing because no rows satisfy filter criteria. To return rows from the empty result set you need to do aggregation. So you need:
(SELECT max(id) FROM members WHERE user_id = 1225282512438558720)
UNION ALL
(SELECT max(id) FROM channels WHERE channel_id = 720694686028791971)
UNION ALL
(SELECT max(id) FROM guilds WHERE guild_id = 831900150115991605);
For multiple columns or results, you can left-join an unary row table to each of your inputs
WITH dual AS (select 1)
(SELECT COALESCE(id, 0) FROM dual LEFT JOIN members ON user_id = 1225282512438558720)
UNION ALL
(SELECT COALESCE(id, 0) FROM dual LEFT JOIN channels ON channel_id = 720694686028791971)
UNION ALL
(SELECT COALESCE(id, 0) FROM dual LEFT JOIN guilds ON guild_id = 831900150115991605);
the query works well but when iam adding group by it gives me [Error] ORA-01427 here is the main query

For sure I couldn't understand very well your query. You could improve your post for next time.
As answer, I think you should encapsulate your select statment and group by using your select as subquery. It is not the best approach but it may works fine.

I have a junction table in a (SQL Server 2014) database with columns FirstID and SecondID. Given a specific FirstID, I'd like to find all other FirstIDs from the table that have an equivalent set of SecondIDs (even if that set is empty).
Sample Data:
FirstId SecondId
1 1
1 2
2 3
3 1
3 2
... ...
In the case of the sample data, if I specified FirstID = 1, then I'd expect 3 to appear in the result set.
I've tried the following so far, which works pretty well except for empty sets:
SELECT FirstSecondEqualSet.FirstId
FROM FirstSecond FirstSecondOriginal
INNER JOIN FirstSecond FirstSecondEqualSet ON FirstSecondOriginal.SecondId = FirstSecondEqualSet.SecondId
WHERE FirstSecondOriginal.FirstId = #FirstId
AND FirstSecondEqualSet.FirstId != #FirstId
GROUP BY FirstSecondEqualSet.FirstId
HAVING COUNT(1) = (SELECT COUNT(1) FROM FirstSecond WHERE FirstSecond.FirstId = #FirstId)
I think it's somehow related to Relational Division with no Remainder (RDNR). See this great article by Dwain Camps for reference.
DECLARE #firstId INT = 1
SELECT
f2.FirstId
FROM FirstSecond f1
INNER JOIN FirstSecond f2
ON f2.SecondId = f1.SecondId
AND f1.FirstId <> f2.FirstId
WHERE
f1.FirstId = #firstId
GROUP BY f2.FirstId
HAVING COUNT(*) = (SELECT COUNT(*) FROM FirstSecond WHERE FirstId = #firstId)
Here is one approach. It counts the number of values for each firstid and then joins on the secondid.
select fs2.firstid
from (select fs1.*, count(*) over (partition by firstid) as numseconds
from firstsecond fs1
where fs1.firstid = #firstid
) fs1 join
(select fs2.*, count(*) over (partition by firstid) as numseconds
from firstsecond fs2
) fs2
on fs1.secondid = fs2.secondid and fs1.numseconds = fs2.numseconds
group by fs2.firstid
having count(*) = max(fs1.numseconds);
I have two SQL queries I want to combine into one. The first one selects all the IDs of the rows I need to add in the second one:
SELECT t.mp_id FROM t_mp AS t
JOIN t_mp_og USING (mp_id)
WHERE og_id = 2928
AND t.description = 'Energy'
The second one should add together the values from the rows returned by the first query. Up until now I've only been able to add several selects with a + in between them. For a dynamic query that adds all the rows returned by query one, I'd like to do something equivalent to "foreach(value from query1){ sum += value }" and return that sum.
SELECT(
(SELECT current_value FROM t_value_time WHERE mp_id = 29280001 AND time_id =
(SELECT time_id FROM t_time WHERE time_stamp =
(SELECT max(time_stamp) FROM v_value AS v WHERE time_stamp is not null AND mp_id = 29280001)))
+
(SELECT current_value FROM t_value_time WHERE mp_id = 29280015 AND time_id =
(SELECT time_id FROM t_time WHERE time_stamp =
(SELECT max(time_stamp) FROM v_value AS v WHERE time_stamp is not null AND mp_id = 29280015)))
+
(SELECT current_value FROM t_value_time WHERE mp_id = 29280022 AND time_id =
(SELECT time_id FROM t_time WHERE time_stamp =
(SELECT max(time_stamp) FROM v_value AS v WHERE time_stamp is not null AND mp_id = 29280022)))
);
My two problems: I don't know how to add all rows in a set, only the manual "+" way. I also don't know how to put the ID from the row into the SELECT getting the value. I've tried AS, but it seems to only work for tables, not single values.
Thanks for you help,
MrB
here is the edited query
select t.mp_id,sum(current_value)
from t_value_time t, t_time tim, v_value v
where
where t.mp_id = v.mp_id
and v.time_stamp is not null
and tim.time_stamp = MAX(v.time_stamp)
and t.time_id=tim.time_id
and t.mp_id in ( 29280001,29280015,29280022)
group by t.mp_id
use SUM() for aggregation
Have you tried SELECT Name, SUM(X) FROM Table GROUP BY Name
SELECT SUM(CURRENT_VALUE )
FROM
T_VALUE_TIME INNER JOIN T_TIME ON T_VALUE_TIME.TIME_ID=T_TIME.TIME_ID
JOIN V_VALUE ON T_TIME.TIME_STAMP=V_VALUE.TIME_STAMP
WHERE T_VALUE_TIME.MP_ID IN (SELECT t.mp_id FROM t_mp AS t JOIN t_mp_og USING (mp_id)
WHERE og_id = 2928
AND t.description = 'Energy' )
AND T_TIME.TIME_ID=(SELECT MAX(TIME_STAMP) FROM V_VALUE WHERE TIME_STAMP IS NOT NULL)
GROUP BY V_VALUE.MP_ID
