Oracle then locates each selected row in the table based on its rowid and does a row-by-row access. Index unique scan – Only one row will be returned from the scan of a unique index. It will be used when there is an equality predicate on a unique (B-tree) index or an index ...
is found, the process starts over again. All the records associated with that ICON (that is, that have the same unique ICON number) are read and processed. Any child ICONs are put on a stack or queue to be processed next. To see the list of possible record types, seeRecord Types. ...
If there is a particular operation that takes a bit more time than the time it takes to supply input to it, a queue may be implemented before it. 队列用于软件,每当某事需要完成用一个异步方式。 如果有比时间采取更多时间它的特殊操作采取对供应输入到它,队列也许在它之前被实施。 [translate] a...
Imagine you have a stack of integers, S, and a queue of integers, Q. Draw a picture of S and Q after the following operations: 1. pushStack(S, 12) 2. enqueue(Q, 8) 3. pushStack (S, 14) 4. pushSta Implement a Stack computer in Javascript. A computer that keeps a stack: when...
Explain what does the following function do: void foo(Queue *q, Stack *s) { while (!q->isEmpty() { s->push(q->dequeue); } while (!s.isEmpty()) { q->enqueue(s,pop()); } } Question 2: What command would you use to change to a different directory? Is B...
When using EXPLAIN PLAN with parallel queries, the database compiles and executes one parallel plan. This plan is derived from the serial plan by allocating row sources specific to the parallel support in the QC plan. The table queue row sources (PX Send and PX Receive), the granule iterato...
