Well ...
I don't know enough about mysql but it must allow you somehow to specify the
column by number as in Oracle and other DBs
SQL> select count(*) from product;
COUNT(*)
----------
10
SQL> select count(1) from product;
COUNT(1)
----------
10
Once you just want to count the rows the performance of your select will be
much better if you specify a column rather than *.
