In this module, you learn how to retrieve data from tables.

All operations on information in an Oracle Database are performed by using SQL statements. A SQL statement is a string of SQL text. The SQL SELECT statement is the command that retrieves data from the database tables.

Sheila will use the SQL SELECT statement to:

• Write queries
• Create SELECT statements that restrict rows
• Sort output
• Display data from many tables
• Customize output with functions embedded in the SELECT statement
