One of the built-in aggregate functions in relational database systems, that returns the number of rows in a result. The argument to the function is nearly always "*", e.g.
SELECT COUNT(*) FROM bookswhich returns the number of rows in the "books" table. If, instead, we say
SELECT COUNT(publisher) FROM booksthen only rows with a non-null value in the "publisher" column will be counted.
