Top Forums Programming SQL*PLUS How to display a count of 0 Post 302932374 by cero on Wednesday 21st of January 2015 07:37:28 AM

You can get a count of 0 by including 'ME' in the data set you select from:
Code:
select owner,table_name,count(table_name)
  from (select owner,table_name from all_tables
        union all
        select 'ME',null table_name from dual)
 where owner = 'ME'
 group by owner,table_name
/

ME                                                                            0

But be careful: count(*) counts the number of records. Because there now is a record with owner='ME' you'd get a result of 1. You get 0 because table_name is null in that record.
