All the statements in the transaction are atomic. A transaction is associated with a single Connection object (and database). A transaction cannot span Connections (or databases).

permits schema and data manipulation statements (DML) to be intermixed within a single transaction. If you create a table in one transaction, you can also insert into it in that same transaction. A schema manipulation statement (DDL) is not automatically committed when it is performed, but participates in the transaction within which it is issued. Because DDL requires exclusive locks on system tables, keep transactions that involve DDL short.
