- Description copied from class:
NonRegisteringDriver
- Try to make a database connection to the given URL. The driver should
return "null" if it realizes it is the wrong kind of driver to connect to
the given URL. This will be common, as when the JDBC driverManager is
asked to connect to a given URL, it passes the URL to each loaded driver
in turn.
The driver should raise an SQLException if it is the right driver to
connect to the given URL, but has trouble connecting to the database.
The java.util.Properties argument can be used to pass arbitrary string
tag/value pairs as connection arguments.
My protocol takes the form:
jdbc:mysql://host:port/database
- Specified by:
connect
in interface java.sql.Driver
- Overrides:
connect
in class NonRegisteringDriver
- Parameters:
url
- the URL of the database to connect toinfo
- a list of arbitrary tag/value pairs as connection arguments
- Returns:
- a connection to the URL or null if it isnt us
- Throws:
java.sql.SQLException
- if a database access error occurs- See Also:
