DB::Connection
Inherits DB::BeginTransaction < DB::SessionMethods < DB::QueryMethods < DB::Disposable < Reference < Object
Database driver implementors must subclass Connection.
Represents one active connection to a database.
Users should never instantiate a Connection manually. Use DB#open or Database#connection.
Refer to QueryMethods for documentation about querying the database through this connection.
Note to implementors
The connection must be initialized in #initialize and closed in #do_close.
Override #build_prepared_statement method in order to return a prepared Statement to allow querying.
Override #build_unprepared_statement method in order to return a unprepared Statement to allow querying.
See also Statement to define how the statements are executed.
If at any give moment the connection is lost a DB::ConnectionLost should be raised. This will allow the connection pool to try to reconnect or use another connection if available.
