index value

基本解釋

They specify the initial value of the index for the iteration and the index value at which iteration should cease, respectively.
它們分別指定迭代索引的初始值以及迭代索引的終止值。
The ending index value of this set of elements can be calculated only by adding up the total number of values that occurred in all preceding slices plus the current slice.
計(jì)算這個(gè)元素集的結(jié)束索引值的惟一方法是，求出前面的所有片和當(dāng)前片中出現(xiàn)的值的總數(shù)。
However, if there are many duplicate rows per distinct index value, and the associated table is highly clustered, the added costs of joining through the index can be slight.
然而，如果每個(gè)不同的索引值都有許多重復(fù)的行，而所關(guān)聯(lián)的表是高度群集的，那么通過索引添加的連接成本可能很低。

OK. What does that say? I'm going to change MinIndex min index to also point there n value is 8, j starts off here, and I say, OK, is the thing I'm looking at here smaller than that? Yes.
好的，這意味著什么？,我打算交換，讓它也指向那里，MinVal是8，j從這里開始,我要找的值比這個(gè)小么？是的。
