public interface RowSet
extends ResultSet

The interface that adds support to the JDBC API for the JavaBeans^TM 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.

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.

Returns:

a string url

Throws:

SQLException - if a database access error occurs

See Also:

            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.

url - a string value; may be null

Throws:

SQLException - if a database access error occurs

See Also:

getUrl()

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.

Parameters:

paramIndex - the first parameter is 1, the second is 2, ...

sqlType - a value from java.sql.Types

typeName - the fully qualified name of an SQL UDT or the type name of the SQL structured type being referenced by a REF type; ignored if the parameter is not a UDT or REF type

Throws:

SQLException - if a database access error occurs

setNull

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.

Parameters:

parameterName - the name of the parameter

sqlType - a value from java.sql.Types

typeName - the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or SQL REF value

Throws:

SQLException - if a database access error occurs or this method is called on a closed CallableStatement

SQLFeatureNotSupportedException - if the JDBC driver does not support this method

setBoolean

void setBoolean(int parameterIndex,
                boolean x)
                throws SQLException

Sets the designated parameter in this RowSet object's command to the given Java boolean value. The driver converts this to an SQL BIT value before sending it to the database.

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the parameter value

Throws:

SQLException - if a database access error occurs

setBoolean

void setBoolean(String parameterName,
                boolean x)
                throws SQLException

Parameters:

parameterName - the name of the parameter

x - the parameter value

Throws:

SQLException - if a database access error occurs or this method is called on a closed CallableStatement
