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.

<u>Accession </u>is the right of an owner of property such as plants or animals to increase in the property. The owner of a cow, for example, owns the calves born to the cow.
A method of gaining property known as accession property law entails the labor- or material-based addition of value to the property.
According to property law, accession refers to the process of obtaining property by enhancing existing property with labour or raw materials like plants. Owning property automatically grants the right to hold anything that is contributed to or created by it .
An illustration of accession is as follows: If someone permits someone else to harvest undesired alfalfa from their land and make it into bales of feed for livestock, that person may then acquire the finished product.
