As the WWW transmission protocol, HTTP is very simple: the client establishes a connection with the remote server, then sends a request, the server processes the request, returns response, and closes the connection. However, this simple process

After the driver class is loaded, an instance of the driver class will be registered. Establish a connection to the database We do not need to directly access the driver class implementing the driver interface in the program, but the driver Manager manages these drivers. The driver interface provides a connect () method to establish a

First, go back to the company to find the installation of SQL Server 2000Program, Cannot be found, so search on the Internet, find it, download it, during installation, because there is a default instance for installing SQL Server 2005, change to the name instance for installing SQL Server 2000, after the installation is successful, enter sql2k \ Dev in system management. The program reports an error. The reason is that the SQL connection string we wrote is as follows: Server = sql2k \ dev;

Check a lot of information, ASP and MySQL connection currently has two ways: one is the use of components, more famous is MYSQLX, but a pity to 99 dollars. Two is to use MYODBC to connect, let's look at the second way. Platform for testing: MySQL 4.0 for Radhat Linux (you can also use for Windows) Windows 2003 Standard Edition Windows XP 中文版 I.

Thank the party, thanks to CCTV, thanks to the search engine, this does not find a good article, special turned around and share. There are 3 ways to connect to access in PHP. (1) Create the system data source, with the ODBC function provided by PHP. (2) You can also use PHP's ODBC functions, but do not create a data source. Open Datebase

the newly generated logical connection object is valid. When the associated pooledconnection.getconnection is called, any previously existing connection objects are automatically closed. The Listener (Connection pool manager) is not notified of the event. A connection pool manager shuts down physical connections by calling the Pooledconnection.close method. This method is typically only called in a specific environment: when the application server encounters a normal shutdown when the con
