COUNT Functions in MariaDB

The MariaDB COUNT() function is used to get a count of the given expression. We can use the COUNT() function with the column name and required expression. The MariaDB count function uses the single expression, distinct clause, and other database functions to get the required COUNT. The NULL values are not counted until they are explicitly included using the COUNT(*).

COUNT() can be combined with other aggregate functions like SUM(), AVG(), MIN(), and MAX() for various analysis tasks.

SELECT COUNT(aggregate_expression)  
FROM table_name  
[WHERE conditions];
