In Oracle Pl-sql, the left and right connections can also be implemented in the following wayExample:SELECT Stu_name, class_nameform students, Classeswhere students.classid (+) = Classes.idThe above SQL query uses the right connection.That is, the other side of the location where "(+)" is the direction of the connection.Right connection description all records to the right of the equal sign are displayed, regardless of whether they are matched on the left side,That is to say, in the above exampl

to the Internet. In fact, many network faults are not caused by problems with network switches, routers, network cards and other devices, but by poor quality of Network cables, crystal heads, or socket modules. Network disconnection or slow speed is mostly caused by poor network quality and high impedance signal attenuation. In overcast and rainy weather, disconnection often occurs, most of which is caused by bad quality of metal connectors of crysta

The SOS guy gave an integrated method of apache + tomcat + connectors-Linux Enterprise Application-Linux server application information. The following is a detailed description. You have installed apache, Jdk, tomcat, and mod_jk.so. Configure # mod_jk.conf and workers. properties Configure mod_jk.conf as follows: # Point out the location of the workers. properties file required for mod_jk module work JkWorkersFile/usr/local/apache2/conf/workers. prope

[] = "8.0.0"; static const char sw_rev[] = sw_version_string; #undef str# undef xstr#undef _string_ OK to here I need the function has been done. Everybody just take a debugging tool to see it, it's OK. Careful study of the implementation of the principle, feel their own understanding of the definition of the macro into a level ... It's not that complicated, actually. S was stringified when it was used in Str, so it was not macro-expanded first. But s are an ordinary argument to Xstr, so it's c

Createprogram in WebGL. Use the function Attachshader when assigning shaders to program objects. The first parameter of the Attachshader function is the program object, and the second parameter is the shader.After the shader assignment ends. Depending on the program object, to connect Two shaders, this time using the Linkprogram function, the parameter is the program object.and generate shaders. To infer whether the connection to the shader was successful, use the Getprogramparameter function a

to NiO in the current http1.1 protocol, and if there is nokeepalive attribute added, in most scenarios, NiO did not pull the gap with bio too big, and even some scenes, Tomcat's bio model is higher than NIO;There is no point in comparing performance here, because performance testing is a test in different application types, different hardware environments, different soft armor versions, and even different JDK performance differences are very large, objective factors, and Tomcat's Web server is

to a remote host asynchronously. For example, the GUI program opens the connection via a button, but we do not want the GUI interface to freeze until the connection is complete. The Boost::asio provides an asynchronous way to connect.Use Bind shared_ptr.#include 　　If you want to pass a Boost::asio object, we generally use the SHARED_PTR smart pointer. Because most objects are non-copyable that cannot be copied, and we determine that the object remains valid for the duration of the call.We use b
