Thanks Lars.
I am currently working on migrating some PL/SQL scripts to HANA and we are using record counts as a test measure. In a particular case of cascaded left outer joins, the numbers dont tally. HANA proposes the count in the Left table as the count of the join while Oracle proposes more.
I am told that there is an difference in the way Oracle and HANA treat join counts - Oracle seems to pick the count in left table + count of matching records while HANA picks only the count of left tables. While I am sure of the HANA behaviour am not quite sure of Oracle's. There is 1:1 relation between left and right table. Or this is a coding issue.
I have also tried using rows tables and the record count is the same. The count in the constituent tables tally, its the join that seems to be acting differently.
Pl advise. Thanks.
