I am trying to sum two values across a UNION. Like:
SELECT
sum(target_value) FROM table
UNION ALL
SELECT
sum(target_value) FROM table_2
But rather than getting the 2 sum values, I want them to also be summed.
How should I go about doing this?
You can try using this in a subquery and calculate at the outer query. Ensure you use UNION ALL to evade the duplicate check
SELECT SUM(a) target_value
FROM
(SELECT
sum(target_value) a FROM table
UNION ALL
SELECT
sum(target_value) a FROM table_2) ;
You can use the WITH clause to do this:
WITH CTE AS (SELECT SUM(target_value) as FirstSum
FROM table
UNION
SELECT
SUM(target_value) as FirstSum
FROM table_2)
SELECT SUM(FirstSum) AS TotalSum FROM CTE
Please see the example below:
create table #temp (x int)
create table #temp2 (x2 int)
insert into #temp values (2)
insert into #temp values (3)
insert into #temp2 values (5)
insert into #temp2 values (6)
select t.col1,t.col2,t.col1+t.col2 as Total
from (
SELECT (select sum(x) FROM #temp) as col1,
(select sum(x2) FROM #temp2) as col2
) t

I have two tables that I want to union together then perform some math functions on the combined table.
I know how to do the math for each separate table, but throwing in a union table to go off of is out of my league.
Here's the math for one table using column header "UnitsReceived" and "AsnPsUnits"
The other table would have headers: "cUnitsReceived" and "cAsnPsUnits"
select VendName,
1-abs(((cast(sum(UnitsReceived) as decimal(5,0))) - (cast(sum(AsnPsUnits) as decimal(5,0)))) /(cast(sum(AsnPsUnits) as decimal(5,0)))) as ASNpsAcc
from VenTest2
where ID<20
group by VendName
How would I perform this function after the union of two tables?
You'll need to get the unioned tables into some table object before performing your function. This could be done using:
A Common Table Expression
with cte as (
select ID, VALUE from A
union all
select ID, VALUE from B
)
select
*
,myfunction(VALUE) as MyFunctionResult
from
cte
A temp table
select ID, VALUE into #myTempTable from A
insert into #myTempTable select ID, VALUE from B
select
*
,myfunction(VALUE) as MyFunctionResult
from
#myTempTable
A table variable
declare #myTableVariable table (ID int, VALUE decimal)
insert into #myTableVariable
select ID, VALUE from A
union all
select ID, VALUE from B
select
*
,myfunction(VALUE) as MyFunctionResult
from
#myTableVariable
A sub query
select
*
,myfunction(VALUE) as MyFunctionResult
from
(
select ID, VALUE from A
union all
select ID, VALUE from B
) mySubQuery
This will help with the subq being the union
select VendName,
1-abs(((cast(sum(UnitsReceived) as decimal(5,0))) - (cast(sum(AsnPsUnits) as decimal(5,0)))) /(cast(sum(AsnPsUnits) as decimal(5,0)))) as ASNpsAcc
from
(
select ID, UnitsReceived, AsnPsUnits from VenTest2 where ID<20
union
select ID1, UnitsReceived1, AsnPsUnits1 from VenTest1
)a
group by VendName
This is not the way, brothers:
select VendName,
1-abs(((cast(sum(UnitsReceived) as decimal(10,2))) - (cast(sum(AsnPsUnits) as decimal(10,2)))) /(cast(sum(AsnPsUnits) as decimal(10,2)))) as ASNpsAcc
from VenTest2
where ID<10
group by VendName
union
select cVendName,
1-abs(((cast(sum(cUnitsReceived) as decimal(10,2))) - (cast(sum(casnpsunits) as decimal(10,2)))) /(cast(sum(cAsnPsUnits) as decimal(10,2)))) as ASNpsAcc
from CTest
where id <10
group by cvendname
I created Tables T1 and T2. I managed to add their sum, but I can't seem to add the sum of the T1 and T2 together (10+12 = 22) by adding a sum() in the beginning of the code.
CREATE TABLE T1(kW int)
CREATE TABLE T2(kW int)
SELECT T1C1, T2C1
FROM
( select SUM(Kw) T1C1 FROM T1 ) A
CROSS JOIN
( select SUM(Kw) T2C1 FROM T2 ) B
BEGIN
INSERT INTO T1 VALUES ('4');
INSERT INTO T1 VALUES ('1');
INSERT INTO T1 VALUES ('5');
INSERT INTO T2 VALUES ('7');
INSERT INTO T2 VALUES ('2');
INSERT INTO T2 VALUES ('3');
END
You should use union all to create a "virtual" column from the columns in the two tables:
SELECT SUM(kw)
FROM (SELECT kw FROM t1
UNION ALL
SELECT kw FROM t2) t
Try using a stored procedure. Doing so you will be able to store the sum of each table on a separated variable and then return the SUM of those two variables.
You can also make a UNION ALL and SUM the column you want. Notice that you should a UNION ALL to avoid eliminating duplicated values.
Another approach is to add the results of the two subqueries directly, using the built-in dummy table dual as the main driving table:
select ( select SUM(Kw) FROM T1 )
+ ( select SUM(Kw) FROM T2 ) as total
from dual;
TOTAL

I'm trying to get maximum repeat of integer in table I tried many ways but could not make it work. The result I'm looking for is as:
"james";"108"
As this 108 when I concat of two fields loca+locb repeated two times but others did not I try below sqlfiddle link with sample table structure and the query I tried... sqlfiddle link
Query I tried is :
select * from (
select name,CONCAT(loca,locb),loca,locb
, row_number() over (partition by CONCAT(loca,locb) order by CONCAT(loca,locb) ) as att
from Table1
) tt
where att=1
please click here so you can see complete sample table and query I tried.
Edite: adding complete table structure and data:
CREATE TABLE Table1
(name varchar(50),loca int,locb int)
;
insert into Table1 values ('james',100,2);
insert into Table1 values ('james',100,3);
insert into Table1 values ('james',10,8);
insert into Table1 values ('james',10,8);
insert into Table1 values ('james',10,7);
insert into Table1 values ('james',10,6);
insert into Table1 values ('james',0,7);
insert into Table1 values ('james',10,0);
insert into Table1 values ('james',10);
insert into Table1 values ('james',10);
and what I'm looking for is to get (james,108) as that value is repeated two time in entire data, there is repetion of (james,10) but that have null value of loca so Zero value and Null value is to be ignored only those to be considered that have value in both(loca,locb).

I have a scenario where i need to pull a temp table data at run time in 1 select sql query. The below does not work. Any advise?
select * from
(
insert into #temp3
select * from GetOrgs('14090',0,1)
)
You can use OUTPUT clause with INSERTED to insert and select using a single query.
INSERT INTO #temp3 (col1, col2,...)
OUTPUT INSERTED.col1, INSERTED.col2, ...
SELECT c1, c2, ...
FROM yourTable
...
Fiddle demo here
I have two tables , table 1 and table 2.
The fields of table 1 are :
book,pen,pencil,bag
The fields of table 2 are :
car,van,book,bike,pencil
When I run the query I want the query to ignore the duplicate or common fields and return the other field.
The output should be as follows,
car,van,bike,pen,bag
Perhaps:
SELECT x.thing FROM
(
SELECT thing FROM dbo.Table1
UNION ALL
SELECT thing FROM dbo.Table2
) X
GROUP BY x.thing
Having Count(*) = 1
Demo
However, this will also remove items that are duplicates in their table which might or might not be desired.
Have you tried sth like this:
delete form X
where (car =
Select distinct car
from X
where x);
distinct--> return the differents values.
try this one:
declare #table1 table (col1 varchar(max))
declare #table2 table (col1 varchar(max))
insert into #table1 values
('book'),('pen'),('pencil'),('bag')
insert into #table2 values ('car'),('van'),('book'),('bike'),('pencil')
;with cte
as (
select COUNT(1) as total_item, col1 from (
select col1 from #table1
union all
select col1 from #table2
)a group by col1
)
select col1 from cte where total_item = 1
WITH uniontables AS (
SELECT NULL AS car,
NULL AS van,
book,
NULL AS bike,
pen,
pencil,
bag
FROM [Table 1 ]
UNION
SELECT car,
van,
book,
bike,
NULL AS pen,
pencil,
NULL AS bag
FROM [Table 2 ] )
SELECT DISTINCT * FROM uniontables
