Question

我在子查询中的ORA-00904: "XSRM"."RATER_PERSON_ID": invalid identifier上获得xsrm.rater_person_id。这是一个错误，因为如果我取出子查询和select xsrm.rater_person_id？

，查询工作正常

select xsrm.person_id,
       xsrm.member_id,
       xsrm.rater_person_id,
       xses.date_sent       
from   apex_ebs_extension.xxpay_survey_ratee_members xsrm,
       apex_ebs_extension.xxpay_survey_emails_sent   xses
where  xsrm.reason = '$X$'
and    xsrm.project_id = 1
and    xses.parent_type (+) = 'R'   -- Ratee member
and    xses.parent_id (+) = xsrm.member_id 
and    0 <
(
   select sum(decode(xsa.answer, null, 1, 0))
   from   apex_ebs_extension.xxpay_survey_questions xsq
   left   outer join apex_ebs_extension.xxpay_survey_answers xsa  
   on     xsa.question_id = xsq.question_id
   and    xsa.person_id = xsrm.person_id 
   and    xsa.rater_person_id = xsrm.rater_person_id
   where  xsq.questionnaire_id = 1 
   and    xsq.required_flag = 'Y' 
)

这也同样失败了：

select xsrm.person_id,
       xsrm.member_id,
       xsrm.rater_person_id,
       xses.date_sent       
from   apex_ebs_extension.xxpay_survey_ratee_members xsrm   
left   outer join apex_ebs_extension.xxpay_survey_emails_sent xses
on     xses.parent_id = xsrm.member_id
and    xses.parent_type = 'R'   -- Ratee member
and    xses.email_event_id = :p_email_event_id
where  xsrm.reason = '$X$'
and    xsrm.project_id = 1
and    0 <
(
   select sum(decode(xsa.answer, null, 1, 0))
   from   apex_ebs_extension.xxpay_survey_questions xsq
   left   outer join apex_ebs_extension.xxpay_survey_answers xsa  
   on     xsa.question_id = xsq.question_id
   and    xsa.person_id = xsrm.person_id 
   and    xsa.rater_person_id = xsrm.rater_person_id
   where  xsq.questionnaire_id = 1 
   and    xsq.required_flag = 'Y' 
)

我最近才开始摆弄ansi sql而不是Oracle外连接。

apex_ebs_extension.xxpay_survey_ratee_members结构：

"member_id","project_id","ratee_group_id","person_id","rater_person_id","verifier_person_id","reason","rater_level","position_number","verifier_level"

Answer 1

在Oracle 11g中使用我自己的表测试了这个并得到了同样的错误。显然，Oracle无法在子查询中的连接的 ON子句中使用外部查询中的列。

这肯定对我来说是一个错误，因为这是一个相关的子查询，Oracle似乎没有完全对待它。

Oracle SQL没有在子查询中看到查询列
