Removing group of results if total is 0 - sql

Question

I am using the following table to create a stacked bar chart - its quite a bit larger than this:
ID | Name | foodEaten | total
1 | Sam | Burger | 3
1 | Sam | Pizza | 1
1 | Sam | Kebab | 0
1 | Sam | Cheesecake| 3
1 | Sam | Sandwich | 5
2 | Jeff | Burger | 0
2 | Jeff | Pizza | 0
2 | Jeff | Kebab | 0
2 | Jeff | Cheesecake| 0
2 | Jeff | Sandwich | 0
I need to find a way to remove results like Jeff. Where the entire total for what he ate is 0. I can't think of the easiest way to achieve this. I've tried grouping the entire result by Id and creating a total, but its just not happening.
If the person has eaten a total of 0 food, then he needs to be excluded. But if he hasn't, and he hasn't eaten any kebabs, as shown in my above table, this needs to be included in the result!
So the output needed is:
ID | Name | foodEaten | total
1 | Sam | Burger | 3
1 | Sam | Pizza | 1
1 | Sam | Kebab | 0
1 | Sam | Cheesecake| 3
1 | Sam | Sandwich | 5

Answer 1

Assuming that you want the data as it appears, and not the aggregate out and then exclude:
WITH CTE AS (
SELECT ID,
[Name],
foodEaten,
total,
SUM(total) OVER (PARTITION BY [Name]) AS nameTotal
FROM YourTable)
SELECT ID,
[Name],
foodEaten,
total
FROM CTE
WHERE nameTotal > 0;

Answer 2

select id, name, foodEaten, sum(total) as total from <table> group by ID having sum(total) > 0
Does this work for you?

Answer 3

You can try below -
select id,name
from tablename a
group by id,name
having sum(total)>0
OR
DEMO
select * from tablename a
where not exists (select 1 from tablename b where a.id=b.id group by id,name
having sum(total)=0)

Answer 4

Try this
;WITH CTE (ID , Name , foodEaten , total)
AS
(
SELECT 1 , 'Sam' , 'Burger' , 3 UNION ALL
SELECT 1 , 'Sam' , 'Pizza' , 1 UNION ALL
SELECT 1 , 'Sam' , 'Kebab' , 2 UNION ALL
SELECT 1 , 'Sam' , 'Cheesecake', 3 UNION ALL
SELECT 1 , 'Sam' , 'Sandwich' , 5 UNION ALL
SELECT 2 , 'Jeff' , 'Burger' , 0 UNION ALL
SELECT 2 , 'Jeff' , 'Pizza' , 0 UNION ALL
SELECT 2 , 'Jeff' , 'Kebab' , 0 UNION ALL
SELECT 2 , 'Jeff' , 'Cheesecake', 0 UNION ALL
SELECT 2 , 'Jeff' , 'Sandwich' , 0
)
SELECT ID , Name ,SUM( total) AS Grandtotal
FROM CTE
GROUP BY ID , Name
HAVING SUM( total) >0
Result
ID Name Grandtotal

Answer 5

Using DELETE with HAVING SUM(total) = 0 will remove the group of result which their total is 0
DELETE FROM TableName
WHERE ID IN (SELECT Id FROM TableName GROUP BY ID HAVING SUM(total) = 0)
or if you want to remvoe and select only the records which has sum of total is zero, then
SELECT * FROM TableName
WHERE ID NOT IN (SELECT Id FROM TableName GROUP BY ID HAVING SUM(total) = 0)

Answer 6

Assuming total is never negative, then probably the most efficient method is to use exists:
select t.*
from t
where exists (select 1
from t t2
where t2.name = t.name and
t2.total > 0
);
In particular, this can take advantage of an index on (name, total).
