I was using a LISTAGG which someone here helped but after a few select field, I started to get an ORA error. I would rather use an Oracle subquery to group multiple row results into one row. In the past, I have used STUFF in sqlserver to do this, how would I do this on Oracle.
I have the following query
select d.id, d.name, d.date_sale, d.address, d.city, d.state, d.zipcode, d.description, d.explanation, d.received_date,
SELECT (dd.my_id, dd.customer_name, dd.category, dd.transaction_date, ';'
) AS GROUPED_COLUMNS
from table1 d
left join table2 dd on d.id = dd.my_id
where d.id =1 and d.isActive =1
You can do:
select d.*
(select list_agg(dd.my_id || dd.customer_name || dd.category || dd.transaction_date, ';') within group (order by transaction_date)
from table2 dd
where d.id = dd.my_id
) AS GROUPED_COLUMNS
from table1 d
where d.id = 1 and d.isActive = 1

I am trying to output result from 2 queries in one table but no luck. Tried with UNION and with this template
SELECT x.a, y.b FROM (SELECT * from a) as x, (SELECT * FROM b) as y
with no luck. My queries are:

With both UNION or combined query as mentioned above, I get blank result and no errors.
Also, I cannot wrap the select in brackets and use an alias like (query) a UNION (query2) b as this also brings blank output.
I can output first name + last name in column one of a table, sum_qty on second, some calculation is made based on the qty and it goes in the third column. In the fourth column, I need to output total_sum
Digged here like 20 threads and tried different solutions but no result.

This should achieve the desired result (ie. the resultset that you need to output your table) using the UNION that you were attempting (although a more efficient query could possibly be achieved using a Common Table Expression - which may or may not be available to you, depending on your RDBMS, and the version thereof).

I have a query such as
select
distinct
t.*,
t.name + ' ' + t.lastname as customername
count(t.id) over() as count
from
table t
inner join othertable o
on t.id = o.tableid
where t.blah = 'aaa'
The problem is that the count over() calculates the results before the distinct is executed and therefore returns an incorrect value.
I could remove the distinct and use group by but this will give the count for each group and I want the sum of those values.
I could do a subquery but the problem is this query is getting built up inside an application so I'd have to do some string manipulation to add the where clause to the subquery and main sql body.
Is there a way to get the count show the results after the distinct is executed?
Thanks
This should solve the problem
select count(v.col_a) over() as count,
v.*
from (select distinct t.col_a, t.col_b, ... --all columns you need
t.name + ' ' + t.lastname as customername
from table t
inner join othertable o on t.id = o.tableid
where t.blah = 'aaa') v
Use group by, but use the correct expression:
select t.*,
t.name + ' ' + t.lastname as customername
sum(count(t.id)) over() as total_count
from table t inner join
othertable o
on t.id = o.tableid
where t.blah = 'aaa'
group by . . .
For each row from table tClass matching a given where clause,
join on the first row in tEv, sorted by time, where tEv.class_id = tClass.class_id
The following code throws the error
ORA-01799: a column may not be outer-joined to a subquery
select
c.class_id,
c.class_name,
e.start_time,
e.ev_id
from
tClass c
left join tEv e on (
e.ev_id = (
select
ss1.ev_id
from (
select
ed.ev_id
from
tEvDisp ed,
tEv e
where
ed.class_id = c.class_id
and ed.viewable = 'Y'
and ed.display_until > localtimestamp
and e.ev_id = ed.ev_id
order by
e.start_time
) ss1
where
rownum = 1
)
)
where
c.is_matching = 'Y';
How can this be rewritten to do what is described?
The above is for oracle, but needs to work in sqlite (substituting where necessary)
No idea about SQLite - that would need to be a separate question if this doesn't work - but for Oracle you could do something like this:
select c.class_id,
c.class_name,
e.start_time,
e.ev_id
from tClass c
left join (
select class_id, ev_id, start_time
from (
select ed.class_id,
ed.ev_id,
e.start_time,
row_number() over (partition by ed.class_id order by e.start_time) as rn
from tEvDisp ed
join tEv e on e.ev_id = ed.ev_id
where ed.viewable = 'Y'
and ed.display_until > localtimestamp
)
where rn = 1
) e on e.class_id = c.class_id
where c.is_matching = 'Y';
This uses a subquery which finds the most tEv data, using an analytic row_number() to identify the latest data for each class_id, which is restricted by the rn = 1 filter.
That subquery, consisting of at most one row per class_id, is then used the left outer join against tClass.
This sort of construct should get you what you need. You can fix the details.
select c.classid
, c.classname
, temp.maxstarttime
from tClass c left join (
select c.classid id
max(e.start_time) maxstarttime
from tClass join tEv on tEv.classId = tClass.ClassId
where whatever
group by c.classid) temp on c.classid = temp.id
I'm trying to print out the results from the "GermanDB" Database first, while also showing everything from the Boston DB that was not in the German database. Can this be done in one query?
My query (the bold part functions but does not order the way I want)
select * from (
SELECT DISTINCT a.ProductRef
FROM GERMANDB.dbo.LOCATIONS AS a INNER JOIN GERMANDB.dbo.ITEMS AS b ON a.ProductRef = b.ProductRef
WHERE b.ACTIVE=1
) ta
UNION select * from
SELECT DISTINCT c.ProductRef
FROM BOSTONDB.dbo.LOCATIONS AS c INNER JOIN BOSTONDB.dbo.ITEMS AS d ON c.ProductRef = d.ProductRef
WHERE c.ACTIVE=1 (c.ProductRef NOT IN
(SELECT ProductRef FROM GERMANDB.dbo.ITEMS where ACTIVE=1))
) tb
order by ta.ProductRef** , tb.productRef
Just add one field to signal the priority. Like this:
select *, 0 as Priority from (
SELECT DISTINCT a.ProductRef
FROM GERMANDB.dbo.LOCATIONS AS a INNER JOIN GERMANDB.dbo.ITEMS AS b ON a.ProductRef = b.ProductRef
WHERE b.ACTIVE=1
) ta
UNION select *, 1 as Priority from
SELECT DISTINCT c.ProductRef
FROM BOSTONDB.dbo.LOCATIONS AS c INNER JOIN BOSTONDB.dbo.ITEMS AS d ON c.ProductRef = d.ProductRef
WHERE c.ACTIVE=1 (c.ProductRef NOT IN
(SELECT ProductRef FROM GERMANDB.dbo.ITEMS where ACTIVE=1))
) tb
order by Priority, ProductRef
I have to do an self join on a table. I am trying to return a list of several columns to see how many of each type of drug test was performed on same day (MM/DD/YYYY) in which there were at least two tests done and at least one of which resulted in a result code of 'UN'.
I am joining other tables to get the information as below. The problem is I do not quite understand how to exclude someone who has a single result row in which they did have a 'UN' result on a day but did not have any other tests that day.
Query Results (Columns)
County, DrugTestID, ID, Name, CollectionDate, DrugTestType, Results, Count(DrugTestType)
I have several rows for ID 12345 which are correct. But ID 12346 is a single row of which is showing they had a row result of count (1). They had a result of 'UN' on this day but they did not have any other tests that day. I want to exclude this.
I tried the following query
select
c.desc as 'County',
dt.pid as 'PID',
dt.id as 'DrugTestID',
p.id as 'ID',
bio.FullName as 'Participant',
CONVERT(varchar, dt.CollectionDate, 101) as 'CollectionDate',
dtt.desc as 'Drug Test Type',
dt.result as Result,
COUNT(dt.dru_drug_test_type) as 'Count Of Test Type'
from
dbo.Test as dt with (nolock)
join dbo.History as h on dt.pid = h.id
join dbo.Participant as p on h.pid = p.id
join BioData as bio on bio.id = p.id
join County as c with (nolock) on p.CountyCode = c.code
join DrugTestType as dtt with (nolock) on dt.DrugTestType = dtt.code
inner join
(
select distinct
dt2.pid,
CONVERT(varchar, dt2.CollectionDate, 101) as 'CollectionDate'
from
dbo.DrugTest as dt2 with (nolock)
join dbo.History as h2 on dt2.pid = h2.id
join dbo.Participant as p2 on h2.pid = p2.id
where
dt2.result = 'UN'
and dt2.CollectionDate between '11-01-2011' and '10-31-2012'
and p2.DrugCourtType = 'AD'
) as derived
on dt.pid = derived.pid
and convert(varchar, dt.CollectionDate, 101) = convert(varchar, derived.CollectionDate, 101)
group by
c.desc, dt.pid, p.id, dt.id, bio.fullname, dt.CollectionDate, dtt.desc, dt.result
order by
c.desc ASC, Participant ASC, dt.CollectionDate ASC
This is a little complicated because the your query has a separate row for each test. You need to use window/analytic functions to get the information you want. These allow you to do calculate aggregation functions, but to put the values on each line.
The following query starts with your query. It then calculates the number of UN results on each date for each participant and the total number of tests. It applies the appropriate filter to get what you want:
with base as (<your query here>)
select b.*
from (select b.*,
sum(isUN) over (partition by Participant, CollectionDate) as NumUNs,
count(*) over (partition by Partitipant, CollectionDate) as NumTests
from (select b.*,
(case when result = 'UN' then 1 else 0 end) as IsUN
from base
) b
) b
where NumUNs <> 1 or NumTests <> 1
Without the with clause or window functions, you can create a particularly ugly query to do the same thing:
select b.*
from (<your query>) b join
(select Participant, CollectionDate, count(*) as NumTests,
sum(case when result = 'UN' then 1 else 0 end) as NumUNs
from (<your query>) b
group by Participant, CollectionDate
) bsum
on b.Participant = bsum.Participant and
b.CollectionDate = bsum.CollectionDate
where NumUNs <> 1 or NumTests <> 1
If I understand the problem, the basic pattern for this sort of query is simply to include negating or exclusionary conditions in your join. I.E., self-join where columnA matches, but columns B and C do not:
select
[columns]
from
table t1
join table t2 on (
t1.NonPkId = t2.NonPkId
and t1.PkId != t2.PkId
and t1.category != t2.category
)
Put the conditions in the WHERE clause if it benchmarks better:
select
[columns]
from
table t1
join table t2 on (
t1.NonPkId = t2.NonPkId
)
where
t1.PkId != t2.PkId
and t1.category != t2.category
And it's often easiest to start with the self-join, treating it as a "base table" on which to join all related information:
select
[columns]
from
(select
[columns]
from
table t1
join table t2 on (
t1.NonPkId = t2.NonPkId
)
where
t1.PkId != t2.PkId
and t1.category != t2.category
) bt
join [othertable] on (<whatever>)
join [othertable] on (<whatever>)
join [othertable] on (<whatever>)
This can allow you to focus on getting that self-join right, without interference from other tables.
