sql - Oracle Listagg Sub query - 


select e.pem_id          id,      e.pem_subject     subject,      e.pem_content     content,      e.pem_sent_date   sentdate,      e.pem_ref_id      referenceid,      e.pem_from_usr_id userid,      null              misc,      (listagg(str.str_us_id, ', ') within group(order '') attachedusers       proj_email_usrs eu left outer join st_register str on       eu.pmu_str_id = str.str_id eu.pmu_pem_id = '26' group '')   proj_email e  e.pem_prj_id = '33' ,    e.pmu_pem_id = '26' ,    e.pem_status = 's';

it throwing error as

ora-01722: invalid number

01722. 00000 - "invalid number"

*cause: specified number invalid.

*action: specify valid number.

i assume want query this:

select e.pem_id id, e.pem_subject subject, e.pem_content content,        e.pem_sent_date sentdate, e.pem_ref_id referenceid,           e.pem_from_usr_id userid, null misc,        (select listagg(str.str_us_id, ', ') within group (order str.str_us_id)         proj_email_usrs eu left outer join              st_register str              on eu.pmu_str_id = str.str_id         eu.pmu_pem_id = e.pmu_pem_id  -- correlation clause        ) attachedusers proj_email e  e.pem_prj_id = 33 , e.pmu_pem_id = 26 , e.pem_status = 's' ;

comments:

  • added select before listagg(). needed subquery.
  • remove group by. not needed, because want subquery return 1 row.
  • removed single quotes constants numbers. use single quotes string , date constants.
  • added correlation clause subquery.
  • moved name of column outside subquery, named in result.
  • added order by column within group. not necessary, reasonable keep ids in order.
