This is done while the table is off-line during a nightly batch window.
这是在一个每夜批处理窗口中当表离线的时候完成的。
If you haven't already done so, don't forget to delete any trace files and turn off tracing by removing the command line parameter in the batch file.
如果您还没有这样做，不要忘记删除所有跟踪文件并通过移除批处理文件中的命令行参数来关闭跟踪。
For example, batch applications that must execute many update operations serially are often better off executing SQL statement in sequence without all the extra object hydration.
例如，必须连续执行多个更新操作的批处理应用程序通常能够更好地依次执行sql语句，而无需所有额外的对象交互。
