Class Description

                                                                      
 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 TSQLResult and TSQLRow.                          
                                                                      


TSQLServer* Connect(const char *db, const char *uid, const char *pw)
 The db should be of the form:  <dbms>://<host>[:<port>][/<database>],
 e.g.:  mysql://pcroot.cern.ch:3456/test, oracle://srv1.cern.ch/main, ...
 The uid is the username and pw the password that should be used for
 the connection. Depending on the <dbms> the shared library (plugin)
 for the selected system will be loaded. When the connection could not
 be opened 0 is returned.
