I have 4 sql statements, each returns 2 columns
select count(id) open, sum(amount) from A where status = 1 group by est_id
result: 25 | 4400
select count(id) close, sum(amount) from A where status = 2 group by est_id
result: 0 | 0
select count(id) stop, sum(amount) from A where status = 3 group by est_id
result: 20 | 4000
I need to return the result of the 4 sql sql statement in one, for example:
25 | 4400| active
0 | 0 | inactive
20 | 4000| close
regards
As mentioned by #bluefeet you're looking for the UNION ALL operator.
select count(id) as c1, sum(amount) as c2, 'active' as c3 from A where status = 1 group by est_id
union all
select count(id), sum(amount), 'inactive' from A where status = 2 group by est_id
union all
select count(id), sum(amount), 'close' from A where status = 3 group by est_id
The column names in the combined resultset will be taken from the first component resultset.

Below is the sample data
If I pass lot name as a parameter, I want to return employees who has greater than 0 records in The specific Lot . Not just the one record but all the records of that employee.
Table A
Empid lotname itemcount
1 A 1
1 B 1
2 B 0
3 B 1
3 C 0
Parameter - B
Result :
Empid lotname itemcount
1 A 1
1 B 1
3 B 1
3 C 0
Because employee 3 and 1 has count in B lot. All the employee lot details should be returned.
select data.* from A data,
(select Empid,count(lotname)
from A
group by Empid
having count(lotname)>1) MulLotEmp
where data.lotname='B'
and data.Empid=MulLotEmp.Empid;
Check if this query solves your problem. In this I created a inner table first for your first requirement that emp with multiple lot, then I mapped this table with actual table with condition of input lot name.
If I understand correctly, you want all "1" and then only "0" if there is no "1".
One method is:
select a.*
from a
where itemcount = 1 or
not exists (select 1 from a a2 where a2.empid = a.empid and a2.itemcount = 1);
In Oracle, you can use the MAX analytic function:
SELECT Empid,
lotname,
itemcount
FROM (
SELECT t.*,
MAX( itemcount ) OVER ( PARTITION BY Empid ) AS max_itemcount
FROM table_name t
)
WHERE max_itemcount = 1;
So, for you sample data:
CREATE TABLE table_name ( Empid, lotname, itemcount ) AS
SELECT 1, 'A', 1 FROM DUAL UNION ALL
SELECT 1, 'B', 1 FROM DUAL UNION ALL
SELECT 2, 'B', 0 FROM DUAL UNION ALL
SELECT 3, 'B', 1 FROM DUAL UNION ALL
SELECT 3, 'C', 0 FROM DUAL;
This outputs:
EMPID | LOTNAME | ITEMCOUNT
----: | :------ | --------:
1 | A | 1
1 | B | 1
3 | B | 1
3 | C | 0
db<>fiddle here
The analytic function
sum(case when LOTNAME = 'B' /* parameter */ then ITEMCOUNT end) over (partition by EMPID) as lot_itemcnt
calculates for each customer the total number of items with the selected lot.
Feel free to use it as a bind variable, e.g.
sum(case when LOTNAME = ? /* parameter */ then ITEMCOUNT end) over (partition by EMPID) as lot_itemcnt
The whole query is than as follows
with cust as (
select
EMPID, LOTNAME, ITEMCOUNT,
sum(case when LOTNAME = 'B' /* parameter */ then ITEMCOUNT end) over (partition by EMPID) as lot_itemcnt
from tab)
select
EMPID, LOTNAME, ITEMCOUNT
from cust
where lot_itemcnt >= 1;
Consider this table:
[Table1]
------------------------
| Person_ID | Yes | No |
|-----------|-----|----|
| 1 | 1 | 0 |
|-----------|-----|----|
| 1 | 1 | 0 |
|-----------|-----|----|
| 2 | 0 | 1 |
|-----------|-----|----|
| 2 | 0 | 1 |
|-----------|-----|----|
| 3 | 1 | 0 |
|-----------|-----|----|
| 3 | 1 | 0 |
|-----------|-----|----|
| 3 | 0 | 1 |
|-----------|-----|----|
| 3 | 1 | 0 |
------------------------
I need a distinct count on Person_ID to get the number of people that are marked Yes and No. However, if someone has a single instance of No, they should be counted as a No and not be included in the Yes count no matter how many Yes they have.
My first thought was to try something similar to:
select count(distinct (case when Yes = 1 then Person_ID else null end)) Yes_People
, count(distinct (case when No = 1 then Person_ID else null end)) No_People
from Table1
but this will result in 3 being counted in both the Yes and No counts.
My desired output would be:
--------------------------
| Yes_People | No_People |
|------------|-----------|
| 1 | 2 |
--------------------------
I'm hoping to avoid the performance hit from having to evaluate a subquery against each row but if it has to be the way to go I will accept that.
Aggregate first at the person level and then overall:
select sum(yes_only) as yes_only,
sum(1 - yes_only) as no
from (select person_id,
(case when max(yes) = min(yes) and max(yes) = 1
then 1
end) as yes_only
from t
group by person_id
) t
You can first group them by the person.
Then the CASE for the Yes people can have a not No condition.
SELECT
COUNT(CASE WHEN No = 0 AND Yes = 1 THEN Person_ID END) AS Yes_People,
COUNT(CASE WHEN No = 1 THEN Person_ID END) AS No_People
FROM
(
select Person_ID
, MAX(Yes) as Yes
, MAX(No) as No
FROM Table1
GROUP BY Person_ID
) q
You could use a window function to rank the rows for a single person_id to prioritize a 'No' over a 'Yes', but that will require a subquery
select count(case when yes=1 then 1 end) as yes_count,
count(case when no=1 then no_count) as no_count
from (
select person_id, yes, no, row_number() over (order by no desc, yes desc) as rn
from table1
)
where rn = 1
The inner subquery plus the where filter will get you a single row per person_id, giving priority to the 'no' records.
This of course assumes yes/no are mutually exclusive, and if that's true, you should probably change the model to a single field.
Think you need to precheck every person with a window function
with t as (select 1 p_id, 1 yes, 0 no from dual
union all select 1 p_id, 1 yes, 0 no from dual
union all select 2 p_id, 0 yes, 1 no from dual
union all select 2 p_id, 0 yes, 1 no from dual
union all select 3 p_id, 1 yes, 0 no from dual
union all select 3 p_id, 0 yes, 1 no from dual
union all select 3 p_id, 1 yes, 0 no from dual)
, chk as (
select max(no) over (partition by p_id) n
, max(yes) over (partition by p_id) y
, p_id
from t)
-- select * from chk;
select count(distinct decode(y-n,1,p_id,null )) yes_people
, count(distinct decode(n,1,p_id,null )) no_people
from chk
group by 1;
You can use Conditional aggregation as following:
SQL> with table1 as (select 1 PERSON_ID, 1 yes, 0 no from dual
2 union all select 1 PERSON_ID, 1 yes, 0 no from dual
3 union all select 2 PERSON_ID, 0 yes, 1 no from dual
4 union all select 2 PERSON_ID, 0 yes, 1 no from dual
5 union all select 3 PERSON_ID, 1 yes, 0 no from dual
6 union all select 3 PERSON_ID, 0 yes, 1 no from dual
7 union all select 3 PERSON_ID, 1 yes, 0 no from dual)
8 SELECT
9 SUM(CASE WHEN NOS = 0 AND YES > 0 THEN 1 END) YES_PEOPLE,
10 SUM(CASE WHEN NOS > 0 THEN 1 END) NO_PEOPLE
11 FROM
12 (
13 SELECT
14 SUM(NO) NOS,
15 PERSON_ID,
16 SUM(YES) YES
17 FROM TABLE1
18 GROUP BY PERSON_ID
19 );
YES_PEOPLE NO_PEOPLE

I am using DB Browser for SQLite. I have a table in the following format:
+-----------+-------------------------------------+
| search_id | search_town |
+-----------+-------------------------------------+
| 1 | town1,town3 |
| 2 | town2,town4,town5 |
| 3 | town3,town5 |
| 4 | town2,town5 |
| 5 | town2,town3,town4 |
+-----------+-------------------------------------+
I would like to do a COUNT on the number of times town1 through town5 has appeared under search_town, and then rank in descending order the towns based on their respective counts. So far I have the following query:
SELECT SUM(CASE WHEN search_location LIKE '%town01%' THEN 1 ELSE 0 END) AS town01,
SUM(CASE WHEN search_location LIKE '%town02%' THEN 1 ELSE 0 END) AS town02,
SUM(CASE WHEN search_location LIKE '%town03%' THEN 1 ELSE 0 END) AS town03,
SUM(CASE WHEN search_location LIKE '%town04%' THEN 1 ELSE 0 END) AS town04,
SUM(CASE WHEN search_location LIKE '%town05%' THEN 1 ELSE 0 END) AS town05
FROM searches
...but am unable to do an ORDER BY as the towns and their counts are output as columns instead of rows in this format
+-------+-------+-------+-------+-------+
| town1 | town2 | town3 | town4 | town5 |
+-------+-------+-------+-------+-------+
| 12 | 31 | 12 | 24 | 12 |
+-------+-------+-------+-------+-------+
Is there another approach to this? Appreciate any comments.
You are turning your output in a single row using CASE WHEN, to convert it into multiple rows, you can try like following.
;WITH cte
AS (SELECT *
FROM (VALUES ('Town1'),
('Town2'),
('Town3'),
('Town4'),
('Town5')) T(town))
SELECT Count(*) [Count],
C.town
FROM [TABLE_NAME] T
INNER JOIN cte C
ON T.search_location LIKE '%' + C.town + '%'
GROUP BY C.town
ORDER BY Count(*) DESC
Online DEMO
Another approach can be using UNION ALL.
SELECT *
FROM (SELECT Count(*) s,
'Town1' AS Col
FROM tablename
WHERE search_location LIKE '%town1%'
UNION ALL
SELECT Count(*) s,
'Town2' AS Col
FROM tablename
WHERE search_location LIKE '%town2%'
UNION ALL
SELECT Count(*) s,
'Town3' AS Col
FROM tablename
WHERE search_location LIKE '%town3%'
UNION ALL
SELECT Count(*) s,
'Town4' AS Col
FROM tablename
WHERE search_location LIKE '%town4%'
UNION ALL
SELECT Count(*) s,
'Town5' AS Col
FROM tablename
WHERE search_location LIKE '%town5%') t
ORDER BY s DESC
You can use a recursive common-table expression (CTE) to turn the comma-separated list into a set of rows. When the table is normalized, you can group by town and sort by descending count:
WITH rec(town, remain)
AS (
SELECT SUBSTR(search_town, 0, INSTR(search_town, ',')) -- Before ,
, SUBSTR(search_town, INSTR(search_town, ',')+1) || ',' -- After ,
FROM t1
UNION ALL
SELECT SUBSTR(remain, 0, INSTR(remain, ',')) -- Before ,
, SUBSTR(remain, INSTR(remain, ',')+1) -- After ,
FROM rec
WHERE LENGTH(remain) > 0
)
SELECT town
, COUNT(*)
FROM rec
GROUP BY
town
ORDER BY
COUNT(*) DESC
Idea from this blog post. Working example at sqliteonline.
I need a bit of help with a SQL query.
Imagine I've got the following table
id | date | price
1 | 1999-01-01 | 10
2 | 1999-01-01 | 10
3 | 2000-02-02 | 15
4 | 2011-03-03 | 15
5 | 2011-04-04 | 16
6 | 2011-04-04 | 20
7 | 2017-08-15 | 20
What I need is all dates where only one price is present.
In this example I need to get rid of row 5 and 6 (because there is two difference prices for the same date) and either 1 or 2(because they're duplicate).
How do I do that?
select date,
count(distinct price) as prices -- included to test
from MyTable
group by date
having count(distinct price) = 1 -- distinct for the duplicate pricing
The following should work with any DBMS
SELECT id, date, price
FROM TheTable o
WHERE NOT EXISTS (
SELECT *
FROM TheTable i
WHERE i.date = o.date
AND (
i.price <> o.price
OR (i.price = o.price AND i.id < o.id)
)
)
;
JohnHC answer is more readable and delivers the information the OP asked for ("[...] I need all the dates [...]").
My answer, though less readable at first, is more general (allows for more complexes tie-breaking criteria) and also is capable of returning the full row (with id and price, not just date).
;WITH CTE_1(ID ,DATE,PRICE)
AS
(
SELECT 1 , '1999-01-01',10 UNION ALL
SELECT 2 , '1999-01-01',10 UNION ALL
SELECT 3 , '2000-02-02',15 UNION ALL
SELECT 4 , '2011-03-03',15 UNION ALL
SELECT 5 , '2011-04-04',16 UNION ALL
SELECT 6 , '2011-04-04',20 UNION ALL
SELECT 7 , '2017-08-15',20
)
,CTE2
AS
(
SELECT A.*
FROM CTE_1 A
INNER JOIN
CTE_1 B
ON A.DATE=B.DATE AND A.PRICE!=B.PRICE
)
SELECT * FROM CTE_1 WHERE ID NOT IN (SELECT ID FROM CTE2)
I have two result sets that look approximately like this:
Id Name Count
1 Asd 1
2 Sdf 4
3 Dfg 567
4 Fgh 23
But the Count column data is different for the second one and I would like both to be displayed, about like this:
Id Name Count from set 1 Count from set two
1 Asd 1 15
2 Sdf 4 840
3 Dfg 567 81
4 Fgh 23 9
How can I do this in SQL (with union if possible)?
My current SQL, hope this will better explain what I want to do:
(SELECT Id, Name, COUNT(*) FROM Customers where X)
union
(SELECT Id, Name, COUNT(*) FROM Customers where Y)
select *
from
(
SELECT 'S1' as dataset, Id, Name, COUNT(*) as resultcount FROM Customers where X
union
SELECT 'S2',Id, Name, COUNT(*) FROM Customers where Y
) s
pivot
(sum(resultcount) for dataset in (s1,s2)) p
You can do something like:
;WITH Unioned
AS
(
SELECT 'Set1' FromWhat, Id, Name FROM Table1
UNION ALL
SELECT 'Set2', Id, Name FROM Table2
)
SELECT
Id,
Name,
SUM(CASE FromWhat WHEN 'Set1' THEN 1 ELSE 0 END) 'Count from set 1',
SUM(CASE FromWhat WHEN 'Set2' THEN 1 ELSE 0 END) 'Count from set 2'
FROM Unioned
GROUP BY Id, Name;
