Selecting a count into a variable in oracle
The INTO clause is misplaced. It should be:
SELECT COUNT(*) INTO leadscount FROM LEADS_DELETED
you have the into at the wrong place.
Try something like this instead and proceed from there:
declare cnt number;begin select count(*) into cnt from leads_delete;end;
Another way :
declare cnt number; cmd varchar2(100);begin cmd := 'select count(*) from leads_delete'; execute immediate cmd into cnt;end;
