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 XE 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
