return number authid current_user IS
num_rows
number;
stmt
varchar2(2000);
begin
if owner is null then
stmt :
= 'select count(*) from "' || table_name || '"';
else
stmt :
= 'select count(*) from "' || owner || '"."' || table_name || '"';
end if;
execute immediate stmt
into num_rows;
return num_rows;
end;
