asked on SQL only use record with higher value
Hello,
I am using SQL to create a query which is basically a big case when statement involving a lot of codes. However, there can be two records for some of the people in the database.
For Example:
Name |Revenue|
John | $100|
Mike | $200|
Bob | $50|
Bob | $300|
In the above example "Bob" appears twice. In these cases I only want to use the record where the Revenue is highest. So in this case I only want to use the record where the Revenue is $300.
Most of our records only have 1 name so most of the time there is just "John" or "Mike"
Is there a way to do this in SQL?
Thanks for any help,
Mike

Assuming I am only using the records with the highest revenue as stated before.

select case when ID is in ('50x', '20b') then 'New York'
when ID is in ('1', '2', '3') then 'Boston' end as 'City'
from here I would like to be able to sum the count in the database (count is always equal to 1) only when the revenue is at its maximum value
Thanks again

Thank you - I used a max clause in a subquery which got me the results.

I suggest you review answers involving ROW_NUMBER() OVER()
When these are used in combination it is possible to pull complete rows representing "highest" or "latest" etc. without using aggregate functions.

If I wanted to do an aggregate function to get the sum of the count is there any way to do that?
Thanks again,
