16// //
17// TMySQLServer //
18// //
19// MySQL server plugin implementing the TSQLServer interface. //
20// //
21// To open a connection to a server use the static method Connect(). //
22// The db argument of Connect() is of the form: //
23// mysql://<host>[:<port>][/<database>], e.g. //
24// mysql://pcroot.cern.ch:3456/test //
25// //
26// As an example of connecting to mysql we assume that the server is //
27// running on the local host and that you have access to a database //
28// named "test" by connecting using an account that has a username and //
29// password of "tuser" and "tpass". You can set up this account //
30// by using the "mysql" program to connect to the server as the MySQL //
31// root user and issuing the following statement: //
32// //
33// mysql> GRANT ALL ON test.* TO 'tuser'@'localhost' IDENTIFIED BY 'tpass';
34// //
35// If the test database does not exist, create it with this statement: //
36// //
37// mysql> CREATE DATABASE test; //
38// //
39// If you want to use a different server host, username, password, //
40// or database name, just substitute the appropriate values. //
41// To connect do: //
42// //
43// TSQLServer *db = TSQLServer::Connect("mysql://localhost/test", "tuser", "tpass");
44// //
