Question

我在查询中遇到错误：

select
    ES.SHPMNT_REF as "SHIPMENT REF",
    listagg(OH.ONHAND_REF,' ')within group(order by ES.SHPMNT_REF) as "test",
    SO.LOAD as "PORT OF LOADING",
    SO.DSCHRG_CITY as "DEST"
from 
    BRDB.EXPORT_SHIPMENT ES 
    left outer join BRDB.EXPORT_SHIPPING_ORDERS SO on ES.SHPMNT_REF = SO.SHPMNT_REF 
    left outer join BRDB.EXPORT_ONHAND OH on ES.SHPMNT_REF = OH.SHPMNT_REF
where 
    ES.REVENUE_ID = 'G2402467' 
    and ES.SHIPMENT_TYPE in ('EDO','EHO')
group by ES.SHPMNT_REF

以下是我收到的错误：

在GROUP BY子句中未指定在SELECT子句，HAVING子句或ORDER BY子句中指定的以“ DSCHRG_CITY”开头的表达式，或者在具有列功能的SELECT子句，HAVING子句或ORDER BY子句中并且未指定GROUP BY子句。SQLCODE = -119，SQLSTATE = 42803，DRIVER = 4.19.49。 2）[代码：-727，SQL状态：56098]在隐式系统操作类型“ 2”期间发生错误。

我不确定为什么会这样，但是如果我删除了“ SO.LOAD”和“ SO.DSCHRG_CITY”，那么编码就可以了。我在做什么错了？

不使用组

select
  ES.SHPMNT_REF as "SHIPMENT REF",
  listagg(OH.ONHAND_REF,' ')within group(order by ES.SHPMNT_REF) as "test",
  min(SO.LOAD) as "PORT OF LOADING",
  ming(SO.DSCHRG_CITY) as "DEST"
from BRDB.EXPORT_SHIPMENT ES 
left outer join BRDB.EXPORT_SHIPPING_ORDERS SO on 
  ES.SHPMNT_REF = SO.SHPMNT_REF 
left outer join BRDB.EXPORT_ONHAND OH 
  on ES.SHPMNT_REF = OH.SHPMNT_REF
where ES.REVENUE_ID = 'G2402467' and ES.SHIPMENT_TYPE in ('EDO','EHO')
group by ES.SHPMNT_REF

具有分组

select
  ES.SHPMNT_REF as "SHIPMENT REF",
  listagg(OH.ONHAND_REF,' ')within group(order by ES.SHPMNT_REF) as "test",
  SO.LOAD as "PORT OF LOADING",
  SO.DSCHRG_CITY as "DEST"
from BRDB.EXPORT_SHIPMENT ES 
left outer join BRDB.EXPORT_SHIPPING_ORDERS SO on 
  ES.SHPMNT_REF = SO.SHPMNT_REF 
left outer join BRDB.EXPORT_ONHAND OH 
  on ES.SHPMNT_REF = OH.SHPMNT_REF
where ES.REVENUE_ID = 'G2402467' and ES.SHIPMENT_TYPE in ('EDO','EHO')
group by ES.SHPMNT_REF, SO.Load, SO.DSCHRG_CITY

在我的代码中使用LISTAGG时收到错误
