Update less site ranking is the better, of course, for the industry. Site collection does not need more than 1000, these included quantity is very abnormal. 1 updated information on the rankings do not have much value is not more than the value of the update of the larger, updated content to do outside the chain, not necessarily ranked. Does not update the content does not send the chain, the rank is very stable. Site optimization upfront, your site i

Oracle classification sorting/ranking can be achieved through the Aggregate functions rank () and dense_rank.Rank () and dense_rank ():-- Two ranking methods (partition and no partition): use and do not use Partition-- Two calculation methods (continuous and discontinuous), corresponding function: dense_rank, rankThe usage of dense_rank is the same as that of rank (), but there is a difference: When dence_r
PHP to do a ranking, according to the time ranking, the chart is in reverse chronological order, queued fields need to be ordered by time.
The correct queuing sequence and sequence number are reversed 5.4.3.2.1

I'm a master of magic!
Not order by time, okay?
If you sort by ID, you can write this
SELECT * FROM table order by id desc;
Not order by time, okay?This method is OK, but the preceding sequence number is according to Desc, and the back line is
Row_number () is similar to rownum and more powerful (it can be sorted from 1 on each group)
Rank () is the Skip sorting. When there are two second names, the next is the fourth name (also in each group)
Dense_rank () L is a continuous sorting, with two second names still followed by the third.
In contrast, row_number is a http://www.itpub.net/thread-244881-1-1.html without repeated values based on [deptno] for continuous sorting without repeated se
