SQL 使用 sum 不按主键分组

Question

I am trying out a query wherein I want only one single sum for two different rows.

select     sum(holdings) 
from       market_data.mstar_holdings mh
inner join market_data.holder_type ht 
           on ht.holder_type_code = mh.mstar_security_specific_holder_type
where      mstar_investment_id = 'E0USA00AY9' 
           and ht.adjustment_flag = true 
           and ht.is_consolidated =false 
--group by ownership_percentage,
           ht.adjustment_threshold 
having ownership_percentage>ht.adjustment_threshold

Currently, in output, I am getting two records. 1000089 and 616295556 in two rows. But I want the output as 1000089+616295556 in one single row. If I comment the group by line, it is giving me error. Is there any way I'll get only one record each time summing up all holdings rows?

The query you placed in the comments is different from the one posted in the question. At any rate, this works:

select sum(holdings)
from (
    select     sum(holdings) as holdings
    from       market_data.mstar_holdings mh
    inner join market_data.holder_type ht 
               on ht.holder_type_code = mh.mstar_security_specific_holder_type
    where      mstar_investment_id = 'E0USA00AY9' 
               and ht.adjustment_flag = true 
               and ht.is_consolidated =false 
    group by ownership_percentage, ht.adjustment_threshold 
    --having ownership_percentage >ht.adjustment_threshold --explain why you have this here. May need to move elsewhere, such as where statement.
