하위 쿼리 결과의 SUM

Question

숫자 열을 출력하는 하위 쿼리가 있는데 기본 쿼리의 해당 요소와 해당 열의 합을 더하고 싶습니다.

... 
... 
DSR_SEGMENT_LIGNE.SEG_R0 + (

select DSR_MUTUELLES.MUT_R0M 
    from DSR_SEGMENT_LIGNE 
    inner join DSR_NOEUD_SIMUL 
     on DSR_SEGMENT_LIGNE.SEG_ID_NOEUD_DEPART = DSR_NOEUD_SIMUL.NOE_ID_NOEUD 
    inner join DSR_NOEUD_SIMUL DSR_NOEUD_SIMUL_ARRIVEE 
     on DSR_SEGMENT_LIGNE.SEG_ID_NOEUD_ARRIVEE = DSR_NOEUD_SIMUL_ARRIVEE.NOE_ID_NOEUD 
    inner join DSR_LIGNE 
     on DSR_LIGNE.LIG_ID_LIGNE = DSR_SEGMENT_LIGNE.LIG_ID_LIGNE 
    inner join DSR_SECTION_LIGNE 
     on DSR_SEGMENT_LIGNE.SEG_ID_SEGMENT = DSR_SECTION_LIGNE.SEG_ID_SEGMENT 
    inner join DSR_MUTUELLES 
     on DSR_MUTUELLES.SEC_ID_SECTION = DSR_SECTION_LIGNE.SEC_ID_SECTION 
    where DSR_SEGMENT_LIGNE.SEG_NOM = "B" 
    and DSR_LIGNE.LIG_NOM = "3040" 
    group by SUP_ID_SUPPORT_FIN 
    having count(*) = 1 

) as "r0",

나는 select sum(DSR_MUTUELLES.MUT_R0M)을 시도했지만 그 결과는 여전히 숫자 열입니다. 이 문제를 어떻게 해결할 수 있습니까?

편집 : 결과는

MUT_R0M 
==================== 
0,000440189590797144

로 결과를 필요

SELECT SUM(DSR_MUTUELLES.MUT_R0M) 
FROM (

select DSR_MUTUELLES.MUT_R0M 
from DSR_SEGMENT_LIGNE 
inner join DSR_NOEUD_SIMUL 
    on DSR_SEGMENT_LIGNE.SEG_ID_NOEUD_DEPART 
     = DSR_NOEUD_SIMUL.NOE_ID_NOEUD 
inner join DSR_NOEUD_SIMUL DSR_NOEUD_SIMUL_ARRIVEE 
    on DSR_SEGMENT_LIGNE.SEG_ID_NOEUD_ARRIVEE 
     = DSR_NOEUD_SIMUL_ARRIVEE.NOE_ID_NOEUD 
inner join DSR_LIGNE 
    on DSR_LIGNE.LIG_ID_LIGNE 
     = DSR_SEGMENT_LIGNE.LIG_ID_LIGNE 
inner join DSR_SECTION_LIGNE

where DSR_SEGMENT_LIGNE.SEG_NOM = "B" and DSR_LIGNE.LIG_NOM = "3040" 
group by SUP_ID_SUPPORT_FIN 
having count(*) = 1 
) as "r0"...
