Method Detail

connect

public java.sql.Connection connect(java.lang.String url,
                                   java.util.Properties info)
                            throws java.sql.SQLException

Attempts 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 driver manager is asked to connect to a given URL it passes the URL to each loaded driver in turn.

The driver should raise a 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 passed arbitrary string tag/value pairs as connection arguments. Normally at least "user" and "password" properties should be included in the Properties.

Specified by:

connect in interface java.sql.Driver

Parameters:

url - the URL of the database to which to connect

info - a list of arbitrary string tag/value pairs as connection arguments. Normally at least a "user" and "password" property should be included.

Returns:

a Connection object that represents a connection to the URL

Throws:

java.sql.SQLException - if a database access error occurs

connect

public FirebirdConnection connect(FirebirdConnectionProperties properties)
                           throws java.sql.SQLException

Description copied from interface: FirebirdDriver

Connect to the specified database using the specified connection properties.

Specified by:

connect in interface FirebirdDriver

Parameters:

properties - instance of FirebirdConnectionProperties created in FirebirdDriver.newConnectionProperties() method.

Returns:

new connection to the Firebird database.

Throws:

java.sql.SQLException - if an error happened while connecting to the database.

newConnectionProperties

public FirebirdConnectionProperties newConnectionProperties()

Description copied from interface: FirebirdDriver

Create new instance of FirebirdConnectionProperties that can later be used in FirebirdDriver.connect(FirebirdConnectionProperties) call.

Specified by:

newConnectionProperties in interface FirebirdDriver

Returns:

instance of FirebirdConnectionProperties.

acceptsURL

public boolean acceptsURL(java.lang.String url)
                   throws java.sql.SQLException

Returns true if the driver thinks that it can open a connection to the given URL. Typically drivers will return true if they understand the subprotocol specified in the URL and false if they don't.

Specified by:

acceptsURL in interface java.sql.Driver

Parameters:

url - the URL of the database

Returns:

true if this driver can connect to the given URL

Throws:

java.sql.SQLException - if a database access error occurs

getPropertyInfo

public java.sql.DriverPropertyInfo[] getPropertyInfo(java.lang.String url,
                                                     java.util.Properties info)
                                              throws java.sql.SQLException

Gets information about the possible properties for this driver.

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 getPropertyInfo.

Specified by:

getPropertyInfo in interface java.sql.Driver

Parameters:

url - the URL of the database to which to connect

info - a proposed list of tag/value pairs that will be sent on connect open

Returns:

an array of DriverPropertyInfo objects describing possible properties. This array may be an empty array if no properties are required.

Throws:

java.sql.SQLException - if a database access error occurs TODO check the correctness of implementation TODO convert parameters into constants

getMajorVersion

public int getMajorVersion()

Gets the driver's major version number. Initially this should be 1.

Specified by:

getMajorVersion in interface java.sql.Driver

Returns:

this driver's major version number

getMinorVersion

public int getMinorVersion()

Gets the driver's minor version number. Initially this should be 0.

Specified by:

getMinorVersion in interface java.sql.Driver

Returns:

this driver's minor version number

jdbcCompliant

public boolean jdbcCompliant()

Reports whether this driver is a genuine JDBC COMPLIANT^TM driver. A driver may only report 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.

Specified by:

jdbcCompliant in interface java.sql.Driver
