The answer is Count. Count is an aggregate method in SQL that returns the number of rows for a specified column that have non-null values.
<h3>What is the Meaning of Null?</h3>
When a field in a database has no values at all, this is known as null and indicates that the field’s value is unknown.
A null value for a number field, text field, or space value is different from a zero value. Null indicates that no value has been recorded in a database field.
A value and a null cannot be compared. The Structured Query Language query cannot be written as SELECT * FROM Customer where email Address=null, for instance, if it is intended to obtain all customers without email addresses from a Customer Addresses table.

Serial narratives are the type of TV storylines characterized by the ongoing accumulation of detail and lack of closure.
<h3>What are serial narratives?</h3>
A serial in literature is a method of printing or publishing in which a single, larger work—often a work of narrative fiction—is distributed in more manageable, sequential chapters.
Serials differ from episodic television, which relies more on stand-alone episodes, in that their principal story arcs can span entire television seasons or even the entire run of the series, as well as occasionally spinoffs.
Newspapers, comic books, movies, television, and digital communication are among the prominent venues and technology of popular seriality since the middle of the nineteenth century and up to the present.
