#include <TMySQLServer.h>
Open a connection to a MySQL DB server.
The db arguments should be of the form "mysql://<host>[:<port>][/<database>]", e.g.: "mysql://pcroot.cern.ch:3456/test". The uid is the username and pw the password that should be used for the connection.
In addition, several parameters can be specified in url after "?" symbol: timeout=N n is connect timeout is seconds socket=socketname socketname should be name of Unix socket, used for connection multi_statements tell the server that the client may send multiple statements in a single string (separated by ;); multi_results tell the server that the client can handle multiple result sets from multiple-statement executions or stored procedures reconnect=0|1 enable or disable automatic reconnection to the server if the connection is found to have been lost compress use the compressed client/server protocol cnf_file=filename Read options from the named option file instead of from my.cnf cnf_group=groupname Read options from the named group from my.cnf or the file specified with cnf_file option If several parameters are specified, they should be separated by "&" symbol Example of connection argument: TSQLServer::Connect("mysql://host.domain/test?timeout=10&multi_statements");
