如果使用本地排序,缓存就会内部排序。
因此,在决定选择哪种联接方法时,优化器为内部表扫描平衡排序成本和性能优势以便促进决策。
Therefore, when deciding which join method to choose, the optimizer balances the sort cost and the performance benefit for the inner table scan to drive the decision.
一般来说,如果内部索引是良好的集群且预测内部表被多次探测,则使用复合排序的嵌套循环联将受到优化器的青睐。
In general, a nested loop join with sort composite is favored by the optimizer if the inner index is well-clustered and the inner table is expected to be probed many times.
使用内部和外部排序的合并扫描联接 (MSJOIN)
该类型内部的排序还不错,但是请考虑AddressType(参见图2)。
The ordering within the type is okay, but consider AddressType (see Figure 2).
内部电路保护包括滞后热关机,欠压锁定(uvlo)和交叉电流保护。特别功率提升排序。
Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover-current protection. Special power-up sequencing is not required.
这些绘画的创造一些室内空间-一大幅点燃一套鼓,一个人的肺部,在阳光的沐浴节游泳池内部结构排序。
The paintings all create some sort of interior space - a sharply lit drum set, the inner structure of a human lung, a section of a swimming pool bathed in sunlight.
利用梯度排序来保持图像内部的边缘,实验结果也表明改进后的修复结果要优于原算法。

在信贷风险管理方面,外部和内部数据都需要用于评分系统,贷后监管流程中的预防性措施设定,以及对追收工作进行优先重点排序。
In credit risk management, internal and external data is required for scoring purposes, for preventive measures during the credit monitoring process and to prioritize recovery efforts.
一旦它们与磁铁相遇,铁磁性物质内部的“小磁铁”重新排序,方向相同,磁性互相叠加,于是使铁磁性物质显示宏观磁性。
Once they meet with magnets, ferromagnetic materials inside the "small magnets" reordering, same direction, magnetic, and make mutual superposition ferromagnetic materials display macro magnetism.
