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.
