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 the URL is null or 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. These properties take precedence over any properties sent in the URL.

MySQL protocol takes the form:

jdbc:mysql://host:port/database

Specified by:

connect in interface Driver

Overrides:

connect in class NonRegisteringDriver

Parameters:

url - the URL of the database to connect to

info - a list of arbitrary tag/value pairs as connection arguments

Returns:

a connection to the URL or null if it isn't us

Throws:

SQLException - if a database access error occurs or the url is null
