Discussion
The Oracle RDBMS uses the ____ statement to declare a new transaction start and its properties.
Answer: B
Correct answer: SET TRANSACTION
Oracle uses SET TRANSACTION to begin a transaction explicitly and set its properties - read-only or read-write, and the isolation level. Oracle needs no BEGIN: a transaction starts implicitly with the first DML statement, and SET TRANSACTION is used when the properties must be declared. BEGIN TRANSACTION is the SQL Server form.
