This document provides an overview of the key clauses in a SQL SELECT statement: 1. The SELECT, FROM, WHERE, GROUP BY, HAVING, and ORDER BY clauses must be written in a specific order. The SELECT clause chooses the columns and FROM clause specifies the table. 2. The WHERE clause filters rows based on conditions and HAVING filters groups. GROUP BY divides rows into groups and ORDER BY sorts the results. 3. Examples demonstrate how each clause works, such as a SELECT statement that filters rows from a student table where the student ID equals 2.
