public void clearWarnings () throws SQLException

Clears all warnings reported for this Connection object.

Clears all warnings reported for this Connection object.
After a call to this method, the method getWarnings
returns null until a new warning is
reported for this Connection object.
Throws:
- SQLException - SQLException if a database access error occurs or this method is called on a closed connection

public void close () throws SQLException

Releases this Connection object's database and JDBC resources immediately instead of waiting for them to be automatically released.

Calling the method close on a Connection object that is already closed is a no-op.

It is strongly recommended that an application explicitly commits or rolls back an active transaction prior to calling the close method. If the close method is called and there is an active transaction, the results are implementation-defined.

Throws:
- SQLException - SQLException if a database access error occurs

public void commit () throws SQLException

Makes all changes made since the previous commit/rollback permanent and releases any database locks currently held by this Connection object.

Makes all changes made since the previous
commit/rollback permanent and releases any database locks
currently held by this Connection object.

public PreparedStatement prepareStatement (String sql) throws SQLException

Creates a PreparedStatement object for sending parameterized SQL statements to the database.

A SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed.

public void setAutoCommit (boolean autoCommit) throws SQLException

Sets this connection's auto-commit mode to the given state.

Sets this connection's auto-commit mode to the given state. If a connection is in auto-commit mode, then all its SQL statements will be executed and committed as individual transactions. Otherwise, its SQL statements are grouped into transactions that are terminated by a call to either the method commit or the method rollback. By default, new connections are in auto-commit mode.

The commit occurs when the statement completes. The time when the statement completes depends on the type of SQL Statement:

For DML statements, such as Insert, Update or Delete, and DDL statements, the statement is complete as soon as it has finished executing.
For Select statements, the statement is complete when the associated result set is closed.
For CallableStatement objects or for statements that return multiple results, the statement is complete when all of the associated result sets have been closed, and all update counts and output parameters have been retrieved.

NOTE: If this method is called during a transaction and the auto-commit mode is changed, the transaction is committed. If setAutoCommit is called and the auto-commit mode is not changed, the call is a no-op.
Parameters:
- autoCommit - true to enable auto-commit mode; false to disable it
Throws:
- SQLException - if a database access error occurs, setAutoCommit(true) is called while participating in a distributed transaction, or this method is called on a closed connection

Throws:
- SQLException - if a database access error occurs or this method is called on a closed connection
See Also: Connection.getCatalog(),

public void setClientInfo (Properties properties) throws SQLClientInfoException

Sets the value of the connection's client info properties.

Sets the value of the connection's client info properties. The Properties object contains the names and values of the client info properties to be set. The set of client info properties contained in the properties list replaces the current set of client info properties on the connection. If a property that is currently set on the connection is not present in the properties list, that property is cleared. Specifying an empty properties list will clear all of the properties on the connection. See setClientInfo (String, String) for more information.

If an error occurs in setting any of the client info properties, a SQLClientInfoException is thrown. The SQLClientInfoException contains information indicating which client info properties were not set. The state of the client information is unknown because some databases do not allow multiple client info properties to be set atomically. For those databases, one or more properties may have been set before the error occurred.

Parameters:
- properties - the list of client info properties to set

Throws:
- SQLClientInfoException - if the database server returns an error while setting the clientInfo values on the database server or this method is called on a closed connection

Since: 1.6

See Also: setClientInfo(String, String),

public void setClientInfo (String name, String value) throws SQLClientInfoException

Sets the value of the client info property specified by name to the value specified by value.

Applications may use the DatabaseMetaData.getClientInfoProperties method to determine the client info properties supported by the driver and the maximum length that may be specified for each property.

The driver stores the value specified in a suitable location in the database. For example in a special register, session parameter, or system table column. For efficiency the driver may defer setting the value in the database until the next time a statement is executed or prepared. Other than storing the client information in the appropriate place in the database, these methods shall not alter the behavior of the connection in anyway. The values supplied to these methods are used for accounting, diagnostics and debugging purposes only.

The driver shall generate a warning if the client info name specified is not recognized by the driver.

If the value specified to this method is greater than the maximum length for the property the driver may either truncate the value and generate a warning or generate a SQLClientInfoException. If the driver generates a SQLClientInfoException, the value specified was not set on the connection.

The following are standard client info properties. Drivers are not required to support these properties however if the driver supports a client info property that can be described by one of the standard properties, the standard property name should be used.

ApplicationName - The name of the application currently utilizing the connection
ClientUser - The name of the user that the application using the connection is performing work for. This may not be the same as the user name that was used in establishing the connection.
ClientHostname - The hostname of the computer the application using the connection is running on.

Parameters:
- name - The name of the client info property to set
- value - The value to set the client info property to. If the value is null, the current value of the specified property is cleared.

Throws:
- SQLClientInfoException - if the database server returns an error while setting the client info value on the database server or this method is called on a closed connection

Since: 1.6
