TSDBDriver (JDBCDriver 2.0.5 API)

java.lang.Object
- com.taosdata.jdbc.TSDBDriver

所有已实现的接口:

Driver
```
public class TSDBDriver
extends Object
implements Driver
```
The Java SQL framework allows for multiple database drivers. Each driver should supply a class that implements the Driver interface
The DriverManager will try to load as many drivers as it can find and then for any given connection request, it will ask each driver in turn to try to connect to the target URL.
It is strongly recommended that each Driver class should be small and stand alone so that the Driver class can be loaded and queried without bringing in vast quantities of supporting code.
When a Driver class is loaded, it should create an instance of itself and register it with the DriverManager. This means that a user can load and register a driver by doing Class.forName("foo.bah.Driver")
