If i have a table with more than a million records.
Is there any better way to get the count of those records without using "Count " Function.

Thanks in advance

select count(*) from t
is the designed, fastest,and best way to get a count of rows in a table.

select max(rownum) from t
is actually a poorer performing alternative to count(*).
