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.

The government protects farmers against fluctuations in prices, revenues, and yields. It subsidizes their conservation efforts, insurance coverage, marketing, export sales, research, and other activities. Federal aid for crop farmers is deep and comprehensive.
However, agriculture is no riskier than many other industries, and it does not need an array of federal subsidies. Farm subsidies are costly to taxpayers, but they also harm the economy and the environment. Subsidies discourage farmers from innovating, cutting costs, diversifying their land use, and taking other actions needed to prosper in the competitive economy.
