procedure and a trigger Triggers are very similar to stored procedures, and triggers are also sets of SQL statements, the only difference being that triggers cannot be invoked with an EXECUTE statement, but are automatically triggered (activated) when a user executes a Transact-SQL statement. A trigger is a stored procedure that executes when a data in a specified table is modified. Pass- through creates triggers to enforce referential integrity and consistency for logically related data in dif

, and future to implement threads with return resultsThe Executorservice, callable, and future three interfaces are actually executor frameworks. The thread that returns the result is a new feature introduced in the JDK1.5, and with this feature it is no longer necessary to get the return value. And it can be flawed if it is achieved.A task that can return a value must implement the callable interface. Similarly, a task without a return value must implement the Runnable interface.After performin

reasonable allocation of server resources Cpu:apache MySQL in high-load environment, disk IO read and write too much, will certainly occupy a lot of resources, it is inevitable that the CPU occupies too high. Memory: Memory library, database software hard disk: file web2.0 architecture Select MongoDB+redis or mysql+Memcached is a better combination, the logic is simple to use NoSQL current main web site architecture LAMP, LNMP, LLMP now there is a lnamp architecture on the network, which is the

can join, can not delete the original method, but cannot add the instance variableExtension: Extension can add instance variables and methods at the same time, and the method must be implemented, can be regarded as a private classProtocol: A protocol is a list of methods that are shared by multiple classes, and the methods listed in the protocol do not have a corresponding implementationInheritance: Not only can add instance variables and methods, but also can rewrite the method of the original

, frequent new/delete is bound to cause memory space discontinuity, resulting in a large number of fragments, so that program efficiency is reduced. For the stack, there is no problem, because the stack is advanced out of the queue, they are so one by one correspondence, so that there will never be a memory block from the middle of the stack poppedAllocation method: The heap is dynamically allocated and there are no statically allocated heaps. Stacks

. Conversely, when Getfullname () is assigned to the test variable, the context refers to the Global Object (window). This is because test is a property that is implicitly set to the global object. For this reason, the function returns the FullName of the window, that is, the value defined in the first row.Question 5:call () and apply ()Now let you solve the previous problem and make the final Console.log () print Aurelio De Rosa.　　ReplyThe problem can change the function context by forcing the

.x:sorted (iterable,/, *, Key=none, reverse=false), python2.x and sorted are somewhat different, with fewer CMP parameters.Key accepts a function that accepts only one element, the default is NoneReverse is a Boolean value. If set to True, list elements are sorted in reverse order and default to FalseFocus on how key works:key specifies a function that receives a parameter that is used to extract a keyword from each element for comparison. The default value is None.(2). The. Sorted () function s

This is the first part of a series of advanced Java interview questions. This section discusses Java core issues such as mutable parameters, assertions, garbage collection, initializers, tokens, dates, calendars, and so on. What is a mutable parameter? The purpose of the assertion? When do I use assertions? What is garbage collection? Use

pattern:First, declare the shared variable to be volatile;Then, the synchronization between threads is realized by using the atomic condition update of CAs.At the same time, the communication between threads is implemented with volatile read/write and the volatile reading and writing memory semantics of CAs.AQS, Non-blocking data structures and atomic variable classes (classes in the Java.util.concurrent.atomic package), the underlying classes in these concurrent packages, are implemented using
