I currently have some SQL that is used to create an excel report in the following format:
COL1 COL2 COL3
2 1 8
3 7 9
1 2 4
Now what I am trying to do is sum up the total of these each value and insert it at the bottom using UNION ALL (unless of course there is a better way.)
Now the values for each column are generated already by sums. The concept I can't grasp is how to sum all the values for the final row, if this is even possible.
So the output should look like so:
COL1 COL2 COL3
2 1 8
3 7 9
1 2 4
6 10 21
Thanks!
It looks like you want to add
WITH ROLLUP
to the end of your query
eg:
Select sum(a) as col1, sum(b) as col2
from yourtable
group by something
with rollup
Depending on the full nature of your query, you may prefer to use with cube, which is similar. See http://technet.microsoft.com/en-us/library/ms189305(v=sql.90).aspx
select
col1
,col2
,col3
from tableA
union
select
sum(col1)
,sum(col2)
,sum(col3)
from tableA
order by col1,col2,col3
SELECT COL1, COL2, COL3
FROM SomeTable
UNION ALL
SELECT SUM(COL1), SUM(COL2), SUM(COL3)
FROM SomeTable
note. there is also a ROLLUP clause but I think the above would be a simpler solution in this case

Update
Realised I was doing it correctly. The reason why I had the issue was because I didn't realise my data for Col1 wasn't as expected, having some Col1 that associates with multiple Col0 (It was supposed to be Col1:Col0 1:1 relationship. That's why the confusion of it's not working as intended.
Original Question
I'm using SQL query to sum a column for total revenue of distinct values in one of the columns, and return a table with combining with other attributes.
Here's my table:
Col 0 Col1 Col2(unique) Revenue
X 1 A 10
X 1 B 20
X 1 C 0
X 2 D 5
X 2 E 8
Y 3 F 3
Y 3 G 0
Y 3 H 50
Desired output:
Col0 Col1 Revenue
X 1 30
X 2 13
Y 3 53
I tried:
WITH
rev_calc AS (
SELECT
Col0,
Col1,
Col2, ##this is for further steps to combine other tables for mapping after this
SUM(Revenue) AS total_revenue, ##total rev by Col1
FROM table_input
GROUP BY Col1, Col0, Col2 ##Have to group by Col0 and Col2 too as it raised error because of 'list expression'
)
SELECT DISTINCT
table2.mappedOfCol0,
rev_calc.Col1,
rev_calc.Col2,
rev_calc.total_revenue,
FROM another_table AS table2
LEFT JOIN rev_calc
ON rev_calc.Col0 = table2.mappedOfCol0
But getting actual output with multiple rows of revenues under a specific Col1.
For example, when i filter by Col1 = 1 in the output table, I get a list of different revenue amount still:
Col1 total_revenue
1 10
1 20
1 0
I thought the GROUP BY should have sum up the revenue by distinctly under Col1. What did I miss out here? I also tried querying first FROM (SELECT DISTINCT Col1....) way but the sum(revenue) is producing a list of different revenue as well
Newbie to SQL here, appreciate if anyone can share any insights here. Thanks.
Don't you just want aggregation?
select col0, col1, sum(revenue) as revenue
from mytable
group by col0, col1
I don't understand what you are trying to do with col2 in the query. This produces the result you want for the data you showed, that contains a single table.
As per explanation you provided, I think your requirement is aggregate revenue of selective records that map with another table based on Col2 values. If that is the case then you may try following query.
WITH
rev_calc AS (
SELECT
distinct(Col2) as Col2
From table_input
LEFT JOIN another_table
ON another_table.Col2 = table_input.Col2
)
SELECT
Col0,
Col1,
SUM(Revenue) AS total_revenue
FROM table_input
WHERE Col2 in (select Col2 from rev_calc)
GROUP BY Col0, Col1;
I have the following tableA
COL1 COL2 COL3
A 1 10-1-2019
B 4 13-4-2019
A 1 13-4-2019
A 1 10-1-2019
A 1 10-1-2019
C 3 20-4-2020
A 1 13-4-2019
I this is the sql code i wish to write but the count do not accept two elements :
select COL1,COL2,COL3
from TableA
group by COL1,COL2,COL3,
HAVING COUNT(COL1,COL2) > 2
And only the result A 1 10-1-2019 should appear because it is the only one that have the pair COL1 COL3 with more than 2 results(in this case three times). The pair COL1 /COL3 is something like a composed primary key
How can i achieve this ?
My database is Sybase ASE
Thanks in advance.
I think this does what you want:
select COL1, COL2, COL3
from TableA
group by COL1, COL2, COL3,
HAVING COUNT(*) > 2;
Perhaps you have a bad example. But I don't see why you think you need to exclude col2.
I have a table with many columns 50+. in order to take decisions I analyze any variant data.
Actually my query:
SELECT maincol, count(maincol) FROM table where (conditions) group by maincol having count(maincol) > 1
then:
SELECT * FROM table where (conditions) and maincol = (previous result)
before consult displays all rows and I have to search one by one
col1, col2, col3, col4, col5, col6, manycolumns..., colN
5 7 1 13 341 9 123
5 7 2 13 341 5 123
I want to get:
col3, col6
1 9
2 5
because it's difficult searching manually column by column.
- N columns could be different
- I don't have access to credentials, then I can't use a programing language to manage results.
- Working on DB2
This will be a little tedious but worth it. This assumes that col1 through coln are all of the same type. If not, cast each to character in the select clause.
The result set will identify the maincol values that occur more than once that also have one or more columns with differing values. The columns that differ will be named.
Select maincol, colname, count(distinct colvalue)
From (
Select maincol, ‘column1’ as colname, col1 as colvalue
from table
Union
Select maincol, ‘column2’ as colname, col2 as colvalue
from table
Union
Select maincol, ‘column3’ as colname, col3 as colvalue
from table
Repeat this pattern for remaining columns
)
Group by maincol, colname
Having count(distinct colvalue) > 1
You could even join the result set from above with the original table to show the entire row including the name of the columns that differ:
Select b.colname, a.*
From table a, Select(
include entire query from above
) as b
Where a.maincol = b.maincol
I have one Table name Demodata which have two column col1 and col2. data of table is
col1 col2
1 5
1 6
2 7
3 8
3 9
4 10
and after SELECT command we need this data
col1 Col2
1 5
6
2 7
3 8
9
4 10
is this possible then what is query please guide me
Try this
SELECT CASE WHEN RN > 1 THEN NULL ELSE Col1 END,Col2
FROM
(
SELECT *,Row_Number() Over(Partition by col1 order by col1) AS RN
From yourTable
) AS T
No it is not possible.
SQL Server result sets are row based not tree based. You must have a value for each column (alternatively a NULL value).
What you can do is grouping by col1 and run an aggregate function on the values of col2 (possibly the STUFF function).
You can do this in SQL, using row_number():
select (case when row_number() over (partition by col1 order by col2) = 1
then col1
end), col2
from table t
order by col1, col2;
Notice that the ordering is important. The way you have written the result set, the data is ordered by col1 and then col2. Result sets do not have an inherent ordering, unless you include an order by clause.
Also, I have used NULL for the missing values.
And, finally, although this can be done in SQL, it is often preferable to do these types of manipulations on the client side.
What do you want to select on the duplicates, an empty string, NULL, 0, ... ?
I presume NULL, you can use a CTE with ROW_NUMBER and CASE on col1:
WITH CTE AS(
SELECT RN = ROW_NUMBER() OVER (PARTITION BY col1
ORDER BY (SELECT 1))
, col1, col2
FROM Demodata
)
SELECT col1 = CASE WHEN RN = 1 THEN col1 ELSE NULL END, col2
FROM CTE
Demo
In MSAccess I have a table with column
1 Col1, Col2, Col3, Col4.
I want to make this column as rows as shown below using an SQL query preferably using PIVOT TRANSFORM. Any help is appreciated!
1 Col1,
2 Col2
3 Col3
4 Col4
You need to use a UNION or UNION ALL query:
Select 1, Col1 From MyTable
Union All
Select 2, Col2 From MyTable
Union All
Select 3, Col3 From MyTable
Union All
Select 4, Col4 From MyTable
Union All will return rows from every table even if it creates duplicates. Union will effectively group the results together so that you can unique rows at a performance cost.
