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.
For quantitative data, notice the root word 'quantity', which focuses on the amount of something, for example, there are more players on team a than on team b.
For qualitative data, notice the root word quality. Qualitative data focuses on the condition or state of something rather than the amount, for instance, player a does not run as fast as player b.
