The number of records or rows in a table using MySQL can be got by using the COUNT statement.

Explanation:

  • To counts all of the rows in a table, whether they contain NULL values or not, use COUNT
  • That form of the COUNT() function basically returns the number of rows in a result set returned by a SELECT statement
  • The SQL COUNT() function returns the number of rows in a table satisfying the criteria specified in the WHERE clause.
  • It sets the number of rows or non NULL column values.
  • COUNT() returns 0 if there were no matching rows.
  • The SQL COUNT function is an aggregate function that returns the number of rows returned by a query. You can use the COUNT function in the SELECT statement to get the number of employees, the number of employees in each department, the number of employees who hold a specific job, etc.
