boolean |
acceptsURL(java.lang.String url)
Retrieves whether the driver thinks that it can open a connection to the given URL.

java.sql.Connection |
connect(java.lang.String url,
java.util.Properties info)
Attempts to make a database connection to the given URL.

Retrieves the driver's major version number.

getMinorVersion()
Gets the driver's minor version number.

Return the parent Logger of all the Loggers used by this driver.

getPropertyInfo(java.lang.String url,
java.util.Properties info)
Gets information about the possible properties for this driver.

boolean |
jdbcCompliant()
Reports whether this driver is a genuine JDBC Compliant™ driver.

public java.sql.Connection connect(java.lang.String url, java.util.Properties info) throws java.sql.SQLException
The driver should throw an SQLException
if it is the right driver to connect to the given URL but
has trouble connecting to the database.
The Properties
argument can be used to pass arbitrary string tag/value pairs as connection arguments.
Normally at least "user" and "password" properties should be included in the Properties
object.
Note: If a property is specified as part of the url
and is also specified in the Properties
object, it is implementation-defined as to which value will take precedence. For maximum portability, an application
should only specify a property once.

public java.sql.DriverPropertyInfo[] getPropertyInfo(java.lang.String url, java.util.Properties info) throws java.sql.SQLException
The getPropertyInfo
method is intended to allow a generic GUI tool to discover what properties it
should prompt a human for in order to get enough information to connect to a database. Note that depending on
the values the human has supplied so far, additional values may become necessary, so it may be necessary to iterate
though several calls to the getPropertyInfo
method.

true
here if it passes the JDBC compliance tests; otherwise it is required to return false
.
JDBC compliance requires full support for the JDBC API and full support for SQL 92 Entry Level. It is expected that JDBC compliant drivers will be available for all the major commercial databases.
This method is not intended to encourage the development of non-JDBC compliant drivers, but is a recognition of the fact that some vendors are interested in using the JDBC API and framework for lightweight databases that do not support full database functionality, or for special databases such as document information retrieval where a SQL implementation may not be feasible.
