The __function__ feature was originally designed for the C language, however, C + + programmers often needed additional information about their functions, and in Visual Studio 2005, two other non-standard extension features were supported: __funcdname__ and __funcsig __, which is translated into the decorated name and signature of a function, respectively. The decorated name of the function is useful, for example, when you want to check whether two c

used. Disadvantages: The speed of accessing data records is affected to a certain extent; It is difficult to change the data source: JDBC supports multiple databases, and operations between different databases must be different, which makes it very difficult to change the data source. 2. process and principle of connecting to the database through JDBC 1,Load the driver of the specified data

the database has user information, if any, on the output login success can The above is to create the MyDatabase database, and then create the user table, the fields are username, password Before looking at the code, because JDBC is a database connection pool, some methods need to use the Mysql-connector-java-5.1.7-bin.jarJust throw it under the web-inf-lib.

The most common database connection technology in Java isJDBC. At present, almost all mainstream databases provide corresponding JDBC drivers, which can be simply understood.. NET database client DLL ,. net. If netframework does not support databases by default (such as sqllite and MySQL), you must download a dedicated database client DLL file and add a reference to this DLL in vs.net, then you can use it to connect to the database.
