public interface Driver
The JDBC driver uses URLs to specify the location of specific data. URL
format typically takes the form " xxxx:yyyy:SpecificData", where "
xxxx:yyyy" is referred to as the subprotocol and is normally
the same for all of a particular driver. " SpecificData" is a string
which identifies the particular data source that the driver should use.
A driver needs to be registered with a DriverManager. It is
registered and instantiated by calling Class.forName("DriverURL")
with the URL string as argument.
DriverManager| Modifier and Type | Method and Description |
|---|---|
boolean |
acceptsURL(String url)
Returns whether the driver thinks that it can open a connection to the
given URL.
|
Connection |
connect(String url,
Properties info)
Attempts to make a database connection to a data source specified by a
supplied URL.
|
int |
getMajorVersion()
Gets the driver's major version number.
|
int |
getMinorVersion()
Gets the driver's minor version number.
|
DriverPropertyInfo[] |
getPropertyInfo(String url,
Properties info)
Gets information about possible properties for this driver.
|
boolean |
jdbcCompliant()
Reports whether this driver is a genuine JDBC CompliantTM driver.

boolean acceptsURL(String url) throws SQLException
url - the URL to connect to.true if the driver thinks that is can open a connection
to the supplied URL, false otherwise. Typically, the
driver will respond true if it thinks that it can handle
the subprotocol specified by the driver.SQLException - if a database error occurs.Connection connect(String url, Properties info) throws SQLException
url - the URL to connect.info - some properties that should be used in establishing the
connection. The properties consist of name/value pairs of
strings. Normally, a connection to a database requires at
least two properties - for "user" and "password" in order to pass authentication to the database.SQLException - if a database error occurs.int getMajorVersion()
int getMinorVersion()
DriverPropertyInfo[] getPropertyInfo(String url, Properties info) throws SQLException
This method is intended to provide a listing of possible properties that the client of the driver must supply in order to establish a connection to a database. Note that the returned array of properties may change depending on the supplied list of property values.
url - the URL of the database. An application may call this method
iteratively as the property list is built up - for example,
when displaying a dialog to an end-user as part of the
database login process.info - a set of tag/value pairs giving data that a user may be
prompted to provide in order to connect to the database.DriverPropertyInfo records which provide
details on which additional properties are required (in addition
to those supplied in the info parameter) in order to
connect to the database.SQLException - if a database error occurs.boolean jdbcCompliant()
true if it passes all the JDBC compliance
tests.
A driver may not be fully compliant if the underlying database has limited functionality.
true if the driver is fully JDBC compliant, false
otherwise.
