DriverManager

extends Object
java.lang.Object
   ↳ java.sql.DriverManager

Class Overview

Provides facilities for managing JDBC drivers. The android.database and android.database.sqlite packages offer a higher-performance alternative for new code.

Note that Android does not include any JDBC drivers by default; you must provide your own.

The DriverManager class loads JDBC drivers during its initialization, from the list of drivers referenced by the system property "jdbc.drivers".

Public Methods

public static void deregisterDriver (Driver driver)

Added in API level 1

Removes a driver from the DriverManager's registered driver list. This will only succeed when the caller's class loader loaded the driver that is to be removed. If the driver was loaded by a different class loader, the removal of the driver fails silently.

If the removal succeeds, the DriverManager will not use this driver in the future when asked to get a Connection.

Parameters
driver the JDBC driver to remove.
Throws
SQLException if there is a problem interfering with accessing the database.

public static Connection getConnection (String url, Properties info)

Added in API level 1

Attempts to establish a connection to the given database URL.

Parameters
url a URL string representing the database target to connect with
info a set of properties to use as arguments to set up the connection. Properties are arbitrary string/value pairs. Normally, at least the properties "user" and "password" should be passed, with appropriate settings for the user ID and its corresponding password to get access to the corresponding database.
Returns
Connection a Connection to the database identified by the URL. null if no connection can be established.
Throws
SQLException if there is an error while attempting to connect to the database identified by the URL.

public static Connection getConnection (String url, String user, String password)

Added in API level 1

Attempts to establish a connection to the given database URL.

Parameters
url a URL string representing the database target to connect with.
user a user ID used to login to the database.
password a password for the user ID to login to the database.
Returns
Connection a Connection to the database identified by the URL. null if no connection can be established.
Throws
SQLException if there is an error while attempting to connect to the database identified by the URL.

public static Connection getConnection (String url)

Added in API level 1

Attempts to establish a connection to the given database URL.

Parameters
url a URL string representing the database target to connect with.
Returns
Connection a Connection to the database identified by the URL. null if no connection can be established.
Throws
SQLException if there is an error while attempting to connect to the database identified by the URL.

public static Driver getDriver (String url)

Added in API level 1

Tries to find a driver that can interpret the supplied URL.

Parameters
url the URL of a database.
Returns
Driver a Driver that matches the provided URL. null if no Driver understands the URL
Throws
SQLException if there is any kind of problem accessing the database.

public static Enumeration<Driver> getDrivers ()

Added in API level 1

Returns an Enumeration that contains all of the loaded JDBC drivers that the current caller can access.

Returns
Enumeration<Driver> An Enumeration containing all the currently loaded JDBC Drivers.

public static PrintStream getLogStream ()

Added in API level 1

This method was deprecated in API level 1.
Use getLogWriter() instead.

Gets the log PrintStream used by the DriverManager and all the JDBC Drivers.

Returns
PrintStream the PrintStream used for logging activities.

public static PrintWriter getLogWriter ()

Added in API level 1

Retrieves the log writer.

Returns
PrintWriter A PrintWriter object used as the log writer. null if no log writer is set.

public static int getLoginTimeout ()

Added in API level 1

Returns the login timeout when connecting to a database in seconds.

Returns
int the login timeout in seconds.

public static void println (String message)

Added in API level 1

Prints a message to the current JDBC log stream. This is either the PrintWriter or (deprecated) the PrintStream, if set.

Parameters
message the message to print to the JDBC log stream.

public static void registerDriver (Driver driver)

Added in API level 1

Registers a given JDBC driver with the DriverManager.

A newly loaded JDBC driver class should register itself with the DriverManager by calling this method.

Parameters
driver the Driver to register with the DriverManager.
Throws
SQLException if a database access error occurs.

public static void setLogStream (PrintStream out)

Added in API level 1

This method was deprecated in API level 1.
Use setLogWriter(PrintWriter) instead.

Sets the print stream to use for logging data from the DriverManager and the JDBC drivers.

Parameters
out the PrintStream to use for logging.

public static void setLogWriter (PrintWriter out)

Added in API level 1

Sets the PrintWriter that is used by all loaded drivers, and also the DriverManager.

Parameters
out the PrintWriter to be used.

public static void setLoginTimeout (int seconds)

Added in API level 1

Sets the login timeout when connecting to a database in seconds.

Parameters
seconds seconds until timeout. 0 indicates wait forever.
