In the nested loop, the number of iterations will be equal to the number of iterations in the outer loop multiplied by the iterations in the inner loop. In each iteration of the outer loop inner loop execute all its iteration.For each iteration of an outer loop the inner loop re-start a...
There are situations we need to be nested loops in Java, one loop containing another loop like to implement manyO(n^2)or quadratic algorithms e.g.bubble sort,insertion sort, selection sort, andsearching in a two-dimensional array. There are a couple of more situations where you need nesting...

Block Nested-Loop JoinAlgorithm(块嵌套循环连接算法) Block Nested-loop(BNL)连接算法利用缓存外部循环读取的数据行来减少在内表中读取的次数。e.g.假如外表读取并缓存10行数据,缓存传递给以下个内表,内表可以在缓存中直接比较这10行数据,而不用再重新读取外表的10行数据,以数量级的方式减少内表读取次数。
Batched Key Access (BKA) Join算法通过index和join buffer访问joined表,BKA算法支持inner join,outer join 和semi join操作,包括嵌套的outer join,BKA的好处包括提高join性能(由于更有效率的table scan),同时,前文的Block Nested loop(BNL)join 算法被扩展也支持这些join类型。
