Question

I have an employee management application. I am using a MySQL database.

In my application, I have functionality like add /edit/delete /view.

Whenever I run any functionality, one query is fired in the database. Like in add employee, it will fire the insert query.

So I want to do something on my database, so that I see how many queries have been fired till date.

I don’t want to do any changes on my Java code.

You can use SHOW STATUS:

SHOW GLOBAL STATUS LIKE 'Questions'

As documented under Server Status Variables:

The status variables have the following meanings.

[ deletia ]

• Questions

  The number of statements executed by the server. This includes only statements sent to the server by clients and not statements executed within stored programs, unlike the Queries variable. This variable does not count COM_PING, COM_STATISTICS, COM_STMT_PREPARE, COM_STMT_CLOSE, or COM_STMT_RESET commands.

Beware that:

• the statistics are reset when FLUSH STATUS is issued.

• the SHOW STATUS command is itself a statement and will increment the Questions counter.

• these statistics are server-wide and therefore will include other databases on the same server (if any exist)—a feature request for per-database statistics has been open since January 2006; in the meantime one can obtain per-table statistics from google-mysql-tools/UserTableMonitoring.
