public interface: RowSet [javadoc | source]

All Implemented Interfaces:
    ResultSet

All Known Implementing Classes:
    FilteredRowSet, JdbcRowSet, CachedRowSet, SyncResolver, JoinRowSet, WebRowSet

The interface that adds support to the JDBC API for the JavaBeansTM component model. A rowset, which can be used as a JavaBeans component in a visual Bean development environment, can be created and configured at design time and executed at run time.

The RowSet interface provides a set of JavaBeans properties that allow a RowSet instance to be configured to connect to a JDBC data source and read some data from the data source. A group of setter methods (setInt, setBytes, setString, and so on) provide a way to pass input parameters to a rowset's command property. This command is the SQL query the rowset uses when it gets its data from a relational database, which is generally the case.

The RowSet interface supports JavaBeans events, allowing other components in an application to be notified when an event occurs on a rowset, such as a change in its value.

The RowSet interface is unique in that it is intended to be implemented using the rest of the JDBC API. In other words, a RowSet implementation is a layer of software that executes "on top" of a JDBC driver. Implementations of the RowSet interface can be provided by anyone, including JDBC driver vendors who want to provide a RowSet implementation as part of their JDBC products.

A RowSet object may make a connection with a data source and maintain that connection throughout its life cycle, in which case it is called a connected rowset. A rowset may also make a connection with a data source, get data from it, and then close the connection. Such a rowset is called a disconnected rowset. A disconnected rowset may make changes to its data while it is disconnected and then send the changes back to the original source of the data, but it must reestablish a connection to do so.

A disconnected rowset may have a reader (a RowSetReader object) and a writer (a RowSetWriter object) associated with it. The reader may be implemented in many different ways to populate a rowset with data, including getting data from a non-relational data source. The writer can also be implemented in many different ways to propagate changes made to the rowset's data back to the underlying data source.

Rowsets are easy to use. The RowSet interface extends the standard java.sql.ResultSet interface. The RowSetMetaData interface extends the java.sql.ResultSetMetaData interface. Thus, developers familiar with the JDBC API will have to learn a minimal number of new APIs to use rowsets. In addition, third-party software tools that work with JDBC ResultSet objects will also easily be made to work with rowsets.

Method from javax.sql.RowSet Detail:
 public  void addRowSetListener(RowSetListener listener)
    Registers the given listener so that it will be notified of events that occur on this RowSet object.
 public  void clearParameters() throws SQLException
    Clears the parameters set for this RowSet object's command.

    In general, parameter values remain in force for repeated use of a RowSet object. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values, which can be done by calling the method clearParameters.

 public  void execute() throws SQLException
    Fills this RowSet object with data.

    The execute method may use the following properties to create a connection for reading data: url, data source name, user name, password, transaction isolation, and type map. The execute method may use the following properties to create a statement to execute a command: command, read only, maximum field size, maximum rows, escape processing, and query timeout.

    If the required properties have not been set, an exception is thrown. If this method is successful, the current contents of the rowset are discarded and the rowset's metadata is also (re)set. If there are outstanding updates, they are ignored.

    If this RowSet object does not maintain a continuous connection with its source of data, it may use a reader (a RowSetReader object) to fill itself with data. In this case, a reader will have been registered with this RowSet object, and the method execute will call on the reader's readData method as part of its implementation.

 public String getCommand()
    Retrieves this RowSet object's command property. The command property contains a command string, which must be an SQL query, that can be executed to fill the rowset with data. The default value is null.
 public String getDataSourceName()
    Retrieves the logical name that identifies the data source for this RowSet object.
 public boolean getEscapeProcessing() throws SQLException
    Retrieves whether escape processing is enabled for this RowSet object. If escape scanning is enabled, which is the default, the driver will do escape substitution before sending an SQL statement to the database.
 public int getMaxFieldSize() throws SQLException
    Retrieves the maximum number of bytes that may be returned for certain column values. This limit applies only to BINARY, VARBINARY, LONGVARBINARYBINARY, CHAR, VARCHAR, LONGVARCHAR, NCHAR and NVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.
 public int getMaxRows() throws SQLException
    Retrieves the maximum number of rows that this RowSet object can contain. If the limit is exceeded, the excess rows are silently dropped.
 public String getPassword()
    Retrieves the password used to create a database connection. The password property is set at run time before calling the method execute. It is not usually part of the serialized state of a RowSet object.
 public int getQueryTimeout() throws SQLException
    Retrieves the maximum number of seconds the driver will wait for a statement to execute. If this limit is exceeded, an SQLException is thrown.
 public int getTransactionIsolation()
    Retrieves the transaction isolation level set for this RowSet object.
 public Map<?> getTypeMap() throws SQLException
    Retrieves the Map object associated with this RowSet object, which specifies the custom mapping of SQL user-defined types, if any. The default is for the type map to be empty.
 public String getUrl() throws SQLException
    Retrieves the url property this RowSet object will use to create a connection if it uses the DriverManager instead of a DataSource object to establish the connection. The default value is null.
 public String getUsername()
    Retrieves the username used to create a database connection for this RowSet object. The username property is set at run time before calling the method execute. It is not usually part of the serialized state of a RowSet object.
 public boolean isReadOnly()
    Retrieves whether this RowSet object is read-only. If updates are possible, the default is for a rowset to be updatable.

    Attempts to update a read-only rowset will result in an SQLException being thrown.

 public  void removeRowSetListener(RowSetListener listener)
    Removes the specified listener from the list of components that will be notified when an event occurs on this RowSet object.
 public  void setArray(int i,
    Array x) throws SQLException
    Sets the designated parameter in this RowSet object's command with the given Array value. The driver will convert this to the ARRAY value that the Array object represents before sending it to the database.
 public  void setAsciiStream(int parameterIndex,
    InputStream x) throws SQLException
    Sets the designated parameter in this RowSet object's command to the given input stream. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

    Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setAsciiStream which takes a length parameter.

 public  void setAsciiStream(String parameterName,
    InputStream x) throws SQLException
    Sets the designated parameter to the given input stream. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

 public  void setBigDecimal(int parameterIndex,
    BigDecimal x) throws SQLException
    Sets the designated parameter in this RowSet object's command to the given java.math.BigDeciaml value. The driver converts this to an SQL NUMERIC value before sending it to the database.

 public  void setBlob(int parameterIndex,
    InputStream inputStream) throws SQLException
    Sets the designated parameter to a InputStream object. This method differs from the setBinaryStream (int, InputStream) method because it informs the driver that the parameter value should be sent to the server as a BLOB. When the setBinaryStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY or a BLOB

    Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setBlob which takes a length parameter.

 public  void setDate(String parameterName,
    Date x,
    Calendar cal) throws SQLException
    Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database. With a a Calendar object, the driver can calculate the date taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
 public  void setDouble(int parameterIndex,
    double x) throws SQLException

    Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the CallableStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be send to the server as a LONGNVARCHAR or a NCLOB
 public  void setNClob(int parameterIndex,
    Reader reader,
    long length) throws SQLException
    Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB
 public  void setNString(int parameterIndex,
    String value) throws SQLException
    Sets the designated paramter to the given String object. The driver converts this to a SQL NCHAR or NVARCHAR or LONGNVARCHAR value (depending on the argument's size relative to the driver's limits on NVARCHAR values) when it sends it to the database.
 public  void setNString(String parameterName,
    String value) throws SQLException
    Sets the designated paramter to the given String object. The driver converts this to a SQL NCHAR or NVARCHAR or LONGNVARCHAR
 public  void setNull(int parameterIndex,
    int sqlType) throws SQLException
    Sets the designated parameter in this RowSet object's SQL command to SQL NULL.

    Note: You must specify the parameter's SQL type.

 public  void setNull(String parameterName,
    int sqlType) throws SQLException
    Sets the designated parameter to SQL NULL.

    Note: You must specify the parameter's SQL type.

 public  void setNull(int paramIndex,
    int sqlType,
    String typeName) throws SQLException
    Sets the designated parameter in this RowSet object's SQL command to SQL NULL. This version of the method setNull should be used for SQL user-defined types (UDTs) and REF type parameters. Examples of UDTs include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

    Note: To be portable, applications must give the SQL type code and the fully qualified SQL type name when specifying a NULL UDT or REF parameter. In the case of a UDT, the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for UDT and REF parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the typeName parameter is ignored.

 public  void setNull(String parameterName,
    int sqlType,
    String typeName) throws SQLException
    Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

    Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

 public  void setObject(String parameterName,
    Object x) throws SQLException
    Sets the value of the designated parameter with the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types.

    The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

    Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

    This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

 public  void setObject(int parameterIndex,
    Object x) throws SQLException
    Sets the designated parameter in this RowSet object's command with a Java Object. For integral values, the java.lang equivalent objects should be used.

    The JDBC specification provides a standard mapping from Java Object types to SQL types. The driver will convert the given Java object to its standard SQL mapping before sending it to the database.

    Note that this method may be used to pass datatabase-specific abstract data types by using a driver-specific Java type. If the object is of a class implementing SQLData, the rowset should call the method SQLData.writeSQL to write the object to an SQLOutput data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

    An exception is thrown if there is an ambiguity, for example, if the object is of a class implementing more than one of these interfaces.

 public  void setObject(int parameterIndex,
    Object x,
    int targetSqlType) throws SQLException
    Sets the designated parameter in this RowSet object's command with a Java Object. For integral values, the java.lang equivalent objects should be used. This method is like setObject above, but the scale used is the scale of the second parameter. Scalar values have a scale of zero. Literal values have the scale present in the literal.

    Even though it is supported, it is not recommended that this method be called with floating point input values.

 public  void setObject(String parameterName,
    Object x,
    int targetSqlType) throws SQLException
    Sets the value of the designated parameter with the given object. This method is like the method setObject above, except that it assumes a scale of zero.
 public  void setObject(int parameterIndex,
    Object x,
    int targetSqlType,
    int scaleOrLength) throws SQLException
    Sets the designated parameter in this RowSet object's command with the given Java Object. For integral values, the java.lang equivalent objects should be used (for example, an instance of the class Integer for an int). If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified * by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.

    The given Java object will be converted to the targetSqlType before being sent to the database.

    If the object is of a class implementing SQLData, the rowset should call the method SQLData.writeSQL to write the object to an SQLOutput data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

    Note that this method may be used to pass datatabase-specific abstract data types.

 public  void setObject(String parameterName,
    Object x,
    int targetSqlType,
    int scale) throws SQLException
    Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used.

    The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

    Note that this method may be used to pass datatabase- specific abstract data types.

 public  void setString(String parameterName,
    String x) throws SQLException
    Sets the designated parameter to the given Java String value. The driver converts this to an SQL VARCHAR or LONGVARCHAR value (depending on the argument's size relative to the driver's limits on VARCHAR values) when it sends it to the database.
 public  void setTime(int parameterIndex,
    Time x) throws SQLException
    Sets the designated parameter in this RowSet object's command to the given java.sql.Time value. The driver converts this to an SQL TIME value before sending it to the database, using the default java.util.Calendar to calculate it.
 public  void setTime(String parameterName,
    Time x) throws SQLException
    Sets the designated parameter to the given java.sql.Time value. The driver converts this to an SQL TIME value when it sends it to the database.
 public  void setTime(int parameterIndex,
    Time x,
    Calendar cal) throws SQLException
    Sets the designated parameter in this RowSet object's command with the given java.sql.Time value. The driver will convert this to an SQL TIME value, using the given java.util.Calendar object to calculate it, before sending it to the database.
 public  void setTime(String parameterName,
    Time x,
    Calendar cal) throws SQLException
    Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
 public  void setTimestamp(int parameterIndex,
    Timestamp x) throws SQLException
    Sets the designated parameter in this RowSet object's command to the given java.sql.Timestamp value. The driver converts this to an SQL TIMESTAMP value before sending it to the database, using the default java.util.Calendar to calculate it.
 public  void setTimestamp(String parameterName,

 public  void setTimestamp(String parameterName,
    Timestamp x,
    Calendar cal) throws SQLException
    Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
 public  void setTransactionIsolation(int level) throws SQLException
    Sets the transaction isolation level for this RowSet obejct.
 public  void setType(int type) throws SQLException
    Sets the type of this RowSet object to the given type. This method is used to change the type of a rowset, which is by default read-only and non-scrollable.
 public  void setTypeMap(Map<?> map) throws SQLException
    Installs the given java.util.Map object as the default type map for this RowSet object. This type map will be used unless another type map is supplied as a method parameter.
 public  void setURL(int parameterIndex,

 public  void setUrl(String url) throws SQLException
    Sets the URL this RowSet object will use when it uses the DriverManager to create a connection. Setting this property is optional. If a URL is used, a JDBC driver that accepts the URL must be loaded before the rowset is used to connect to a database. The rowset will use the URL internally to create a database connection when reading or writing data. Either a URL or a data source name is used to create a connection, whichever was set to non null value most recently.
