included in my site! Just the sixth day after the rectification! with my own experience and lessons, I would remind you: 1, the site was K, first from their own web site to find the reasons for timely rectification. Because of your site you know the situation. 2, do not rush to write to Baidu, there may be Baidu K you are not the reason you write the problem, lest self-defeating, never turn over the opportunity. 3, do not excessively stack hot words 4, every day to develop a good habit of check

Again hashing:In order to eliminate the original aggregation and two times the aggregation, you can use another method: the re-hashing, two times the aggregation is caused by the two detection algorithm generated by the detection sequence step is always fixed: 1,4,9,16 ...One way x needs to do this is to produce a probe sequence that relies on the keyword, not every keyword. Then, different keywords can use different probe sequences, even if they map

When using a USB flash drive, when you click on the "Safe removal of hardware" and did not unplug the USB flash drive, and suddenly want to continue to use the U disk, how to do? I believe you must first unplug and then reinsert the USB stick. Here's a quick trick to re-enable your USB drive. With DevCon combined with batch processing, the above complex operations can be achieved with a click. The DevCon utility is a command-line utility that can re

Tag: Sum--Execute Start SELECT query statement OTT First arc--with reusing subqueriesFor complex query statements that use the same subquery multiple times, the user may divide the query statement into two statements. The first statement stores the subquery results in a temporary table, and the second query statement uses the staging table to process the data. Starting with Oracle 9i, a subquery can be given a name by using the WITH clause, and all tasks can be completed in one statement, thus a

When emptying a table, reinsert the data and find that the field count of the Auto_increment attribute is not starting at 1, you can use the following command methodDelete from test;ALTER TABLE ' Test ' auto_increment=1(Benefit, you can set auto_increment to start at any value)Tip: If the table columns and data are many, the speed will be very slow, such as 90多万条, will be more than 10 minutes.Method TwoTRUNCATE TABLE test(benefit, simple, auto_increment value restart count)In general we use the

, the lock is implemented by code, to ensure that the lock must be released, you must put unlock () into finally{}* A java.util.concurrent package has been added in JavaSE5.0 to support synchronization. The Reentrantlock class is a re-entrant, mutex, and lock interface that implements the same basic behavior and semantics as using the Synchronized method, and extends its capabilities* Applicable: In the case of resource competition is not very intense

, using the LIMIT clause has no problem, and when the amount of data is very large, the use LIMIT n, m is very inefficient. Because the mechanism of limit is to scan from scratch every time, if need to start from the No. 600000 line, read 3 data, you need to scan to locate 600,000 rows before reading, and the scanning process is a very inefficient process. Therefore, for large data processing, it is very necessary to establish a certain caching mechanism in the application layer (seemingly the b

Because the server 1 minutes to disconnect the idle connection

Label:For programming is to make a variety of data processing, and in general, the final storage of data is the database, the database of SQL operations is very important. If a table in a database holds a large amount of data, and two of the tables have the same data, how can you query the last or the first data of the records associated with this field based on the same field value?First, simply as an experimental point of view, you first need to create a table, and then fill a small amount of
