Detailed Description

Class representing a transaction on a database.

This class is created by the DBI2::reateTransaction() method. It represent a single, hopefully non-nested transaction. You can call query(), select(), insert(), update() and delete() on it, which function exactly the same as the DBI2 counterparts. When the transaction is finished, call commit() or cancel() to commit or cancel the transaction, respectively. If you do not commit or cancel, the transaction will be automatically cancelled when the transaction object goes out of scope or is to be garbage collected. This prevents locked database connections
