In MySQL :
This query allows us to have the total number of "select" on the server (query 1) :
mysql> SELECT VARIABLE_VALUE FROM information_schema.global_status WHERE variable_name like 'com_select';
and this query allows us to know the number of "select" for the current session :
mysql> show status like 'Com_select';
mysql> SHOW SESSION STATUS LIKE 'Com_select';
please, how to have the number of "select" for all current sessions (total) and a query like the first (query 1) , but by date. Thanks.
