Which of the following SQL commands is used to retrieve

Solution

The SELECT statement is a fundamental SQL command used to query and retrieve data from a database. It allows users to specify exactly which columns of data they want to see and from which tables, potentially including conditions for filtering results through the WHERE clause. SELECT can also be used in conjunction with other SQL functions such as JOIN, GROUP BY, and ORDER BY to manipulate and organize the retrieved data effectively. Mastery of the SELECT statement is essential for anyone working with relational databases. Option A (INSERT) is incorrect as this command is used to add new records to a table. Option B (UPDATE) is also incorrect because it modifies existing records rather than retrieving them. Option D (DELETE) is incorrect since it is used to remove records from a table, not to fetch data. Option E (CREATE) is incorrect as this command is used to create new tables or databases, not to retrieve data.
