Question

我正在尝试使用以下查询创建一个交互式报告。

这在SQLPLUS中运行完美，但是当我在APEX中编写此查询并运行报告时，它会抛出错误：

ORA-01427：单行子查询返回多个行

          and ppf.person_id (+) = fu.employee_id ) CREATED_BY,

          and ppf.person_id (+) = fu.employee_id ) UPDATED_BY,

        WHERE  owners.ext_bank_account_id = ieb.ext_bank_account_id
        AND owners.ext_bank_account_id = instrument.instrument_id(+)
        AND payees.ext_payee_id        = instrument.ext_pmt_party_id(+)
        AND payees.payee_party_id      = owners.account_owner_party_id
        AND payees.supplier_site_id    = asa.vendor_site_id
        AND asa.vendor_id              = asp.vendor_id
        AND cbbv.branch_party_id(+)    = ieb.branch_id  
        and payees.org_id = 101
        and hou.organization_id = PAYEES.ORG_ID
        and FLV.LOOKUP_CODE = asp.vendor_type_lookup_code
        and flv.lookup_type  = 'VENDOR TYPE'
        and ft1.territory_code(+) = asa.country
        and ft2.territory_code(+) = ieb.country_code
        and PAYEES.BANK_CHARGE_BEARER = 'SHA';

如果我只是取消注释最后一个where条件，即不会发生此错误 “-and PAYEES.BANK_CHARGE_BEARER ='SHA';”

最后一个条件甚至都不是子查询，因此我无法理解APEX中为什么会出现此错误。在SQLPLUS中，一切正常。另外，如果我在APEX应用程序生成器的SQL Workshop中运行查询，那么它也可以正常工作。仅在运行应用程序时，它才会显示此错误。

此外，如果我从查询中删除此条件，则应用程序可以正常运行，但是当我对此值“ SHA”进行过滤时，也会出现相同的错误。如果选择“ OUR”之类的其他值，效果很好。

能否请您提出我应该做些什么以避免这种错误。

您的投影中有两个子查询：

(select nvl(ppf.full_name, fu.user_name) 
 from fnd_user fu,  per_all_people_f ppf
 where fu.user_id = ieb.created_by
 and ppf.person_id (+) = fu.employee_id ) CREATED_BY,

和

(select nvl(ppf.full_name, fu.user_name) 
 from fnd_user fu,  per_all_people_f ppf
 where fu.user_id = ieb.last_updated_by
 and ppf.person_id (+) = fu.employee_id ) UPDATED_BY,

这些查询中的一个或两个都针对特定的用户/人员组合返回多个记录。您的表似乎是Oracle E-Business Suite表。如果是这样，per_all_people_f是一个日期跟踪表，并且对于给定的person_id可能有多个记录。您应在联接条件上添加一个谓词，以将ppf限制为fu的单个记录。如果您在ieb中创建了日期并更新了日期，那么我将使用这些日期，否则使用sysdate：

(select nvl(ppf.full_name, fu.user_name) 
 from fnd_user fu
 left join per_all_people_f ppf
   on ppf.person_id = fu.employee_id
  and trunc(sysdate) between ppf.effective_start_date and ppf.effective_end_date
 where fu.user_id = ieb.created_by) CREATED_BY,

或

(select nvl(ppf.full_name, fu.user_name) 
 from fnd_user fu
 left join per_all_people_f ppf
   on ppf.person_id = fu.employee_id
  and trunc(ieb.creation_date) between ppf.effective_start_date and ppf.effective_end_date
 where fu.user_id = ieb.created_by) CREATED_BY,

对update by的更改将是相似的，尽管留给读者练习；）
