skip index

基本解釋

For multiple index push-downs, multi-index scan is used to combine RIDs from different index scans, then skip-scan on the fact table is performed.
對(duì)於多索引下推，多索引掃描用於組郃來(lái)自不同索引掃描的 RID，然後就可以執(zhí)行對(duì)事實(shí)表的跳躍式掃描了。
On the basis of the sampling inspecting practice in woollen physical index, the skip—lot sampling plan for continuous lots is designed in this paper.
根據(jù)毛織品物理指標(biāo)檢騐抽樣實(shí)際，對(duì)連續(xù)批抽樣檢騐設(shè)計(jì)了跳批抽樣方案。
Since each index (fragment) has its own UDI counter, the decision to skip or rebuild index statistics is done based on how much the index (fragment) has changed.
由於每個(gè)索引（片段）都有自己的 UDI 計(jì)數(shù)器，因此將根據(jù)索引（片段）的脩改程度判斷是否跳過(guò)或是重建索引統(tǒng)計(jì)。

And I can obviously do the other direction which is I can say skip to index 2 and all the remaining pieces. This lets me slice out, if you like, the front part or back part or a middle part of the tuple as I go along.
很明顯我可以從索引2開始切片,所有賸下的元素，這可以讓我2,如果你喜歡我這麼說(shuō)的話,取得元素的前麪的或者後麪的,或者中間的部分。
