火鸟 SQL 分组依据

Question

我想按列 factd_poste_fact 分组，但出现此错误：

SQL error code = -104.
Invalid expression in the select list (not contained in either an aggregate function or the GROUP BY clause).

代码：

select
   f.fact_n,
   poste_facture ,
   sum_montant_ttc
from 
   factures f
left outer join
   (select
       facture_detail.fact_n,
       (facture_detail.factd_poste_fact) as poste_facture,
       sum(facture_detail.factd_montant_ttc) as sum_montant_ttc
    from 
       facture_detail
    group by    
       (fact_d.fact_n,facture_detail.factd_poste_fact)
group by
    f.fact_n, poste_facture, sum_montant_ttc

Answer 1

您需要在子查询的分组依据中包含 facture_detail.fact_n

SELECT f.fact_n, poste_facture, sum_montant_ttc
FROM factures f
LEFT OUTER JOIN (SELECT fact_n, (factd_poste_fact) AS poste_facture, SUM(factd_montant_ttc) AS sum_montant_ttc
                 FROM facture_detail
                 GROUP BY factd_poste_fact, fact_n
                ) fact_d ON (f.fact_n = fact_d.fact_n)

GROUP BY f.fact_n, poste_facture, sum_montant_ttc
