If any part of the series fails, the database is rolled back to the state prior to the BEGIN TRANSACTION.
如果任何系列的一部分失败，数据库回滚到之前的状态开始交易。
ROLLBACK statement without a transaction or savepoint name always rolls back statements to the outermost BEGIN transaction (explicit or implicit) statement, and cancels the entire transaction.
没有事务名称或保存点名称的ROLLBACK语句总是将语句回退到最外层的BEGIN TRANSACTION(显式或隐式)语句，并且取消整个事务。
Begin, continue, and conclude the transaction entries.
开始、继续并结束这次交易的输入。
开始一个JTA事务。
If defined as NOT NULL, the value corresponds to the start time associated with the most recent transaction (the value of the as ROW BEGIN column).
如果定义为NOT NULL，该值会对应于与最近的事务相关联的开始时间(ASROW begin列的值)。
Applications wanting to begin a transaction, such as updating an order or purchasing a product simply need to invoke the appropriate stored procedure from the application.
想要执行某个事务(例如更新订单或者购买某个产品)的应用程序，只需从应用程序中调用存储过程。
No new work can be processed until a worker thread has completed its transaction and is free to begin executing the next one (Figure 3 depicts this scenario).
在工作线程完成其事务并释放以执行下一个事务前，无法处理任何新工作(图3给出了此场景的图释)。
If you want a new transaction to always begin when the component services were called, you would use the PROPAGATION_REQUIRES_NEW attribute.
如果想在调用组件服务时总是启动新事务，可以使用PROPAGATION _ requires_new属性。
If bean-managed transactions are employed, the developer will determine under what conditions a transaction should begin and end.
如果使用的是bean管理的事务，那么开发人员将确定事务的开始条件和结束条件。
Subsequently it will call the LocalTransactions begin , commit , and rollback methods to control the transaction.
然后，它要调用Localtransactionbegin 、commit和rollback方法来控制事务。
There is a small advantage to preparing the statements outside the BEGIN since the transaction will be slightly smaller in time (with second caveat below), thereby permitting more concurrency.
有一个小的优势在准备语句BEGIN因为事务将略小（与第二警告下面），从而允许更多的并发性。
Once the application calls xa_start to begin the transaction, the work is done under the trusted user ID Newton.
一旦应用程序调用xa_start开始事务，接下来的工作就是在受信任用户IDnewton之下进行的。
To begin, we will create a sample application which USES Hibernate's own connection pooling and transaction management (also referred to as "full cream" architecture).
开始时，我们将创建实例应用程序，这个程序使用Hibernate自己的连接池以及事务管理(同样请参考“fullcream ”架构)。
You can avoid schema changes by preparing inside a transaction, but note that you will need to use BEGIN IMMEDIATE to be sure the database is locked.
你可以避免模式变化，准备在一个事务，但是请注意，您将需要使用BEGINIMMEDIATE可以肯定的是数据库锁定。
Caveat 2: Since you use BEGIN rather than BEGIN IMMEDIATE the database lock is not actually taken until the first statement of the transaction is stepped.
注意2：因为你使用BEGIN而不是BEGINIMMEDIATE数据库锁实际上并不是到的第一个语句的事务了。
Commodities are never too high to begin buying or too low to begin selling. But after the initial transaction, don't make a second unless the first shows a profit.
商品没有高到不该再买的时候，也没有低到不该再卖的时候。不过，在最初的转手后，除非第一手交易获利了，不要再做第二手。
Commodities are never too high to begin buying or too low to begin selling. But after the initial transaction, don't make a second unless the first shows a profit.
