// TSQLServer //
// //
// Abstract base class defining interface to a SQL server. //
// //
// To open a connection to a server use the static method Connect(). //
// The db argument of Connect() is of the form: //
// <dbms>://<host>[:<port>][/<database>], e.g. //
// mysql://pcroot.cern.ch:3456/test, oracle://srv1.cern.ch/main, ... //
// Depending on the <dbms> specified an appropriate plugin library //
// will be loaded which will provide the real interface. //
// //
// Related classes are TSQLStatement, TSQLResult and TSQLRow. //
// //
