Label:Oracle 11g When the SQL statement does not add an order by, it appears that the result is returned in the order of ROWID.I've also seen some of the relevant documentation, and the official meaning of Oracle is that without order by, the order of output is not guaranteed . So, here's the question:If now I select X

Reference from: Two fork tree pre-order, middle sequence, post-order traversal Mutual seeking method (Fancheng) Today we are still concerned about the foundation of the two-fork tree, the relationship between the pre-order, the middle order and the sequential traversal. First, the known pre-

2, but when modifying a table, whether it is a clustered index or a heap of data pages are in natural order to insert data backwards, the offset on the page can be demonstrated. Because the smallest reading unit of a database is a page, the physical order within the page does not matter, just maintaining the logical order of the data within the page.When data is

this series as effective JavaScript 's reading notes. Don't be fooled by the name of the higher-order function. In fact, higher-order functions represent only two types of functions: Functions that accept other functions as arguments Functions that return values as functions With this definition, you may find that you have already used them, typically the callback functions that are passed

In this paper, the optimization of count, table connection order, conditional order, in and exist in SQL optimization is very practical. Details are as follows: One, about count Have you seen some online articles about count (*) and count (columns), is the Count (column) more efficient than count (*)? In fact, the individual feels that count (*) and Count (column) are simply not comparable, COUNT (*) cou

1-byte sequenceBecause different computer systems use different byte sequences to store data, the same 4-byte 32-bit integer is stored in memory in a different way. The byte order is divided into small tail byte sequence (Little endian) and large tail byte sequence (big endian), most of the Intel processor uses the small tail byte sequence, the Motorola processor most uses the big tail (large endian) byte order
