Data | refresh | no Refresh | show due to the recent web site need to use no refresh data, so on the Internet to check some data, no refresh data implementation without the use of JavaScript or XMLHTTP or IFRAME to achieve. Find a code on the Internet is not to use is too inefficient, and some even make my CPU up to 100%, I based on the online code and access to some information, provide the following two cases without refreshing data examples, to ens

If the full table is scanned, assuming 10 data blocks, then only 1000 blocks of data can be accessed, since the data blocks accessed by the full table scan Less, the index will certainly not be used. 3. The leading fuzzy query cannot take advantage of the index (like '%XX ' or like '%xx% ') If there is such a list of code values for ' AAA ', ' AAB ', ' BAA ', ' BAB ', if where code like '%ab ' condition, because the front is Fuzzy, so can not use the order of the index, must go to fin

(semi-synchronous) replication protocol. Once the local disk write is completed and the replication packet reaches the peer node, it is considered to be written on the master node as completed. Data loss can occur in cases where the participating two nodes fail simultaneously because the data in transit may not be committed to the disk.Protocol C:Synchronous replication Protocol. Write is considered complete only if the disk on the local and remote n

MySQL deletes data in several cases and whether to free disk space:1, DROP table table_name immediately free disk space, whether it is InnoDB and MyISAM;2. TRUNCATE TABLE table_name immediately frees up disk space, both InnoDB and MyISAM. Truncate table is somewhat similar to the drop table and then creat, except that the CREATE table process is optimized, such as when the table structure file is already there and so on. So the speed should be close t

I just saw a post posted on the 51testing Forum, saying that I don't have a good idea to write test cases. Are there any good test coverage methods for some complicated functional points, such as advanced queries, do I have to list such detailed test cases? ~~~~ After reading it, I couldn't help but speak. As a tester, designing a test case is my job. If the basic patience of writing a test case is discarde

in a general software company, design and write Test Use Cases has been a very important basic for testers work . However, many software testing practitioners or other departments will always feel that test cases are not necessary to write. We can think of a software development process:Product personnel to determine user needs, product personnel, developers, testers, UE personnel, such as review, developer

There's not much difference in the template of the test case, and I always wanted to find a good test case template when I first came into contact with the test. Typically, the test case template includes the main three items: operating instructions, expected results, and no pass. With these three items, the other is based on your needs to embellish, my blog has a I now use the test requirements and use case template, can refer to. The question is how to fill in the template, that is, how to wri

1. If you want to modify the value of an argument through a function call, you should define the parameter as a reference type;For example, to exchange a two-digit value with the Swap function, you should define the parameter as a reference type2. To obtain multiple result values through a function call, you can also use reference parameters;3. When passing large objects to a function, to avoid copying arguments to adjust efficiency and to use class types that cannot be copied(whose copy constr
