An MQT can be defined at table creation time as maintained by the system or maintained by the user.
MQT可以在创建表时定义，或者定义为系统维护的MQT，或者定义为用户维护的MQT。
As the data for the base table (s) changes, the MQT needs to be updated accordingly.
当基本表中的数据发生改变时，需要相应地更新MQT。
For example, if the base table is DPF partitioned, the design of the MQT should consider whether to replicate the MQT across the data partitions.
例如，如果基本表使用了DPF进行分区，那么MQT的设计就应该考虑是否要在各个数据库分区上复制MQT。
With MQTs, when they are updated to remove the corresponding summary data, it is advisable to use table partitioning on the MQT and to define the same data partitions as on the base table.
对于MQT，当从MQT中删除相应的总结数据时，建议在MQT上使用表分区，并与基本表定义一样的数据分区。
However, the design of an MQT can be affected by which partitioning features are used on the base table.
然而，MQT的设计却可能受到基本表上使用的分区特性的影响。
The use of partitioning features on the base table does not need to take into account whether MQTs will be built upon this table.
基本表上分区特性的使用不需要考虑将来是否会在这个表上创建MQT。
A customer experiences performance issue while refreshing an MQT as part of a batch run.
在批处理运行过程中，当刷新一个MQT时，客户会遇到性能问题。
In the first Chapter of this thesis, some recent results already obtained in magnetic MQT arereviewed, both theoretically and experimentally.
本文第一章回顾了磁的宏观量子效应理论上和实验上已经得到的一些结果。
The paper analyzes existing problems of MQT series pneumatic roof bolter in use and maintenance and puts forward the concrete measures of maintaining the roof bolter.
对MQT系列矿用气动锚索钻机使用及维护中存在的问题进行了分析，提出了维护的具体措施及实施方法。
In the Raman response signals of a Multiple Quantum Coherence with a given order, all possi-ble Single Quantum Transitions and those Multiple Quantum Transition's withlower orders were always accompanied with the given order MQT.
任一阶多量子相干的Raman响应谱中都伴有所有单量子跃迁和低阶多量子跃迁，这一事实表明多量子跃迁是由级联的单量子跃迁组成的。
Not supported are range clustered tables (RCT), materialized query tables (MQT), and typed tables.
不支持范围簇表（RCT）、物化查询表（MQT）和有类型的表。
Maintenance of MQT Series Coalmine Pneumatic Roof Bolter
MQT系列矿用气动锚索钻机的维护
The MQT refresh time is now reduced, because often only the small MQTs based on [CurrentMonthSales] must be refreshed.
MQT重新刷新时间减少，因为通常仅需重新刷新基于[CurrentMonthSales]的小MQT。
Finally, MQTs also add considerations to the roll-in process.
最后，MQT还增加了转入过程中要考虑的因素。
Next, to populate the MQT with some data, we will import data that had been exported from the EMPLOYEE and SALES tables.
接下来，为了填充数据到MQT中，我们将导入从EMPLOYEE和SALES表中导出的数据。
The Development of MQT-60/1.5 Gas Pays the Leg Type to Help the Anchor Rod Drilling Machine
MQT-60/1.5型气动支腿式帮锚杆钻机的研制
The statistical view is kind of like the Materialized Query Table (MQT), except that there is no need for materialization.
统计视图有点类似于物化查询表（MaterializedQueryTable，MQT），不同的是统计视图不需要物化。
Generally, MQTs are updated to remove the corresponding summary data.
通常，MQT也需要更新，以删除相应的总结数据。
Neither REFRESH DEFERRED nor REFRESH IMMEDIATE system-maintained MQTs allow insert, update, or delete operations to be executed against them.
不管是REFRESHDEFERRED还是REFRESHIMMEDIATE类型的系统维护的MQT，对它们的insert、update或delete操作都是不允许的。
To improve performance, federation frequently uses caching, materialized query tables (MQTs), and distributed query optimization and execution.
要改进性能，联合需要经常使用缓存、物理查询表（MQT）以及分布式查询优化和执行。
