Interface RowSet

All Superinterfaces:: ResultSet

public interface RowSet
extends ResultSet

The RowSet interface adds support to the JDBC API for the JavaBeans(TM) component model. A rowset can be used as a JavaBean in a visual Bean development environment. A RowSet can be created and configured at design time and executed at runtime. 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 setXXX() methods provide a way to pass input parameters to a rowset. The RowSet interface supports JavaBeans events, allowing other components in an application to be notified when an important event on a rowset occurs, 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(TM) 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.

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 ResultSets will also easily be made to work with rowsets.

Method Detail

addRowSetListener

public void addRowSetListener(RowSetListener rowSetListener)

RowSet listener registration. Listeners are notified when an event occurs.

Parameters:: rowSetListener - - an event listener

clearParameters

public void clearParameters()
                     throws SQLException

In general, parameter values remain in force for repeated use of a RowSet. 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; this can be done by calling clearParameters.

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

execute

public void execute()
             throws SQLException

Fills the rowset with data. Execute() may use the following properties: url, data source name, user name, password, transaction isolation, and type map to create a connection for reading data. Execute 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 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.

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

getCommand

public String getCommand()

Get the rowset's command property. The command property contains a command string that can be executed to fill the rowset with data. The default value is null.

Returns:: the command string, may be null

getDataSourceName

public String getDataSourceName()

The JNDI name that identifies a JDBC data source. Users should set either the url or data source name properties. The most recent property set is used to get a connection.

Returns:: a data source name

getEscapeProcessing

public boolean getEscapeProcessing()
                            throws SQLException

If escape scanning is on (the default), the driver will do escape substitution before sending the SQL to the database.

Returns:: true if enabled; false if disabled
Throws:: SQLException - - if a database-access error occurs.

getMaxFieldSize

public int getMaxFieldSize()
                    throws SQLException

The maxFieldSize limit (in bytes) is the maximum amount of data returned for any column value; it only applies to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.

Returns:: the current max column size limit; zero means unlimited
Throws:: SQLException - - if a database-access error occurs.

getMaxRows

public int getMaxRows()
               throws SQLException

The maxRows limit is the maximum number of rows that a RowSet can contain. If the limit is exceeded, the excess rows are silently dropped.

Returns:: the current max row limit; zero means unlimited
Throws:: SQLException - - if a database-access error occurs.

getPassword

public String getPassword()

The password used to create a database connection. The password property is set at runtime before calling execute(). It is not usually part of the serialized state of a rowset object.

Returns:: a password

getQueryTimeout

public int getQueryTimeout()
                    throws SQLException

The queryTimeout limit is the number of seconds the driver will wait for a Statement to execute. If the limit is exceeded, a SQLException is thrown.

Returns:: the current query timeout limit in seconds; zero means unlimited
Throws:: SQLException - - if a database-access error occurs.

getTransactionIsolation

                    String typeName)
             throws SQLException

JDBC 2.0 Set a parameter to SQL NULL. This version of setNull should be used for user-named types and REF type parameters. Examples of user-named 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-named or REF parameter. In the case of a user-named 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-named 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-named or REF type then the typeName 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 a SQL user-named type, ignored if the parameter is not a user-named type or REF
Throws:: SQLException - - if a database-access error occurs.

setObject

public void setObject(int parameterIndex,
                      Object object)
               throws SQLException

Set the value of a parameter using an object; use the java.lang equivalent objects for integral values.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument java object 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 SQLData, the rowset should call its method writeSQL() to write it to the SQL data stream. else If the object is of a class implementing Ref, Blob, Clob, Struct, or Array then pass it to the database as a value of the corresponding SQL type. Raise an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of those interfaces.

Parameters:: parameterIndex - - The first parameter is 1, the second is 2, ...; object - - The object containing the input parameter value
Throws:: SQLException - - if a database-access error occurs.

setObject

public void setObject(int parameterIndex,
                      Object object,
                      int targetSqlType)
               throws SQLException

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

Parameters:: parameterIndex - - The first parameter is 1, the second is 2, ...; object - - The object containing the input parameter value; targetSqlType - - The SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
Throws:: SQLException - - if a database-access error occurs.

setObject

public void setObject(int parameterIndex,

                      int j,
                      int scale)
               throws SQLException

Set the value of a parameter using an object; use the java.lang equivalent objects for integral values.

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 its method writeSQL() to write it to the SQL data stream. else If the object is of a class implementing Ref, Blob, Clob, Struct, or Array then 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.

Parameters:: parameterIndex - - The first parameter is 1, the second is 2, ...; object - - The object containing the input parameter value; j - - The SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.; scale - - For java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types this is the number of digits after the decimal. For all other types this value will be ignored
Throws:: SQLException - - if a database-access error occurs.
