Submitting SQL Statements

Submitting a statement is a single line of application code, but the Oracle database performs a series of
actions in response to this submission before it responds to the request. The individual actions performed
depend on the type of SQL statement submitted—a data definition language (DDL) statement for creating
or modifying database objects, a write operation (INSERT, UPDATE, or DELETE), or a query using the
SELECT verb. The actions taken for each of these are detailed in the following table.
