Explanation:
Detailed explanation-1: -A SELECT statement retrieves zero or more rows from one or more database tables or database views. In most applications, SELECT is the most commonly used data manipulation language (DML) command. As SQL is a declarative programming language, SELECT queries specify a result set, but do not specify how to calculate it.
Detailed explanation-2: -FROM is used to specify a table name where a necessary column with data is located. AS is used to create a temporary name for the column headings. GROUP BY is used to group results with similar data. HAVING is used to define a search condition. More items •18-Feb-2022
