Class OPLCachedRowSet OPLCachedRowSet Classes OPLCachedRowSet A OPLCachedRowSet is a disconnected, serializable, scrollable container for tabular data. A primary purpose of the OPLCachedRowSet class is to provide a representation of a JDBC ResultSet that can be passed between different components of a remote application. For example, a OPLCachedRowSet can be used to send the result of a query executed by an Enterprise JavaBeans component running in a server environment over a network to a client running in a web browser. A second use for OPLCachedRowSets is to provide scrolling and updating for ResultSets that don't provide these capabilities themselves. A OPLCachedRowSet can be used to augment the capabilities of a JDBC driver that doesn't have full support for scrolling and updating. Finally, a OPLCachedRowSet can be used to provide Java applications with access to tabular data in an environment such as a thin client or PDA, where it would be inappropriate to use a JDBC driver due to resource limitations or security considerations. The OPLCachedRowSet class provides a means to "get rows in" and "get changed rows out" without the need to implement the full JDBC API.A OPLCachedRowSet object can contain data retrieved via a JDBC driver or data from some other source, such as a spreadsheet. Both a OPLCachedRowSet object and its metadata can be created from scratch. A component that acts as a factory for rowsets can use this capability to create a rowset containing data from non-JDBC data sources.The term 'disconnected' implies that a OPLCachedRowSet only makes use of a JDBC connection briefly while data is being read from the database and used to populate it with rows, and again while updated rows are being propagated back to the underlying database. During the remainder of its lifetime, a OPLCachedRowSet object isn't associated with an underlying database connection. A OPLCachedRowSet object can simply be thought of as a disconnected set of rows that are being cached outside of a data source. Since all data is cached in memory, OPLCachedRowSets are not appropriate for extremely large data sets.The contents of a OPLCachedRowSet may be updated and the updates can be propagated to an underlying data source. OPLCachedRowSets support an optimistic concurrency control mechanism - no locks are maintained in the underlying database during disconnected use of the rowset. Both the original value and current value of the OPLCachedRowSet are maintained for use by the optimistic routines.Synopsis public class OPLCachedRowSet extends BaseRowSet implements RowSetInternal,Serializable,Cloneable { // Public Constructors public OPLCachedRowSet() throws java.sql.SQLException;

ExceptionsSQLExceptionif an error occurs.Create a OPLCachedRowSet object. The object has no metadata.Method absolute(int)absolute Methods absolute Synopsis: public boolean absolute(int row) throws java.sql.SQLException; ExceptionsSQLExceptionif a database-access error occurs, or row is 0, or rowset type is TYPE_FORWARD_ONLY.Move to an absolute row number in the rowset. It notifies listeners that the cursor has moved.If row is positive, moves to an absolute row with respect to the beginning of the rowset. The first row is row 1, the second is row 2, etc.If row is negative, moves to an absolute row position with respect to the end of rowset. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) indicates the next-to-last row, etc.An attempt to position the cursor beyond the first/last row in the rowset, leaves the cursor before/after the first/last row, respectively.Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().Method acceptChanges()acceptChanges Methods acceptChanges Synopsis: public void acceptChanges() throws java.sql.SQLException; ExceptionsSQLExceptionif an error occurs.Propagate all row update, insert, and delete changes to a data source. An SQLException is thrown if any of the updates cannot be propagated. If acceptChanges() fails then the caller can assume that none of the updates are reflected in the data source. The current row is set to the first "updated" row that resulted in an exception, in the case that an exception is thrown. With one exception, if the row that caused the exception is a "deleted" row, then in the usual case, when deleted rows are not shown, the current row isn't affected. When successful, calling acceptChanges() replaces the original value of the rowset with the current value. Note: Both the original and current value of the rowset are maintained. The original state is the value of the rowset following its creation (i.e. empty), or following the last call to acceptChanges(), execute(), populate(), release(), or restoreOriginal(). Internally, a RowSetWriter component is envoked to write the data for each row.Method acceptChanges(Connection)acceptChanges Methods acceptChanges Synopsis: public void acceptChanges(java.sql.Connection _conn) throws java.sql.SQLException; Parameters _conn - a database connection ExceptionsSQLExceptionif an error occurs.Like acceptChanges() above, but takes a Connection argument. The Connection is used internally when doing the updates. This form isn't used unless the underlying data source is a JDBC data source.Method afterLast()afterLast Methods afterLast((( Synopsis: public void afterLast() throws java.sql.SQLException; ExceptionsSQLExceptionif a database-access error occurs, or rowset type is TYPE_FORWARD_ONLY.Moves to the end of the rowset, just after the last row. Has no effect if the rowset contains no rows. It notifies listeners that the cursor has moved.Method beforeFirst()beforeFirst Methods beforeFirst Synopsis: public void beforeFirst() throws java.sql.SQLException; ExceptionsSQLExceptionif a database-access error occurs, or rowset type is TYPE_FORWARD_ONLYMoves to the front of the rowset, just before the first row. Has no effect if the rowset contains no rows. It notifies listeners that the cursor has moved.Method cancelRowDelete()cancelRowDelete Methods cancelRowDelete Synopsis: public void cancelRowDelete() throws java.sql.SQLException; ExceptionsSQLExceptionif an error occurs.Cancels deletion of the current row and notifies listeners that a row has changed. After calling cancelRowDelete() the current row is no longer marked for deletion. An exception is thrown if there is no current row. Note: This method can be ignored if deleted rows aren't being shown (the normal case).Method cancelRowInsert()cancelRowInsert Methods cancelRowInsert Synopsis: public void cancelRowInsert() throws java.sql.SQLException; ExceptionsSQLExceptionif an error occurs.Cancels insertion of the current row and notifies listeners that a row has changed. An exception is thrown if the row isn't an inserted row. The current row is immediately removed from the rowset. This operation cannot be undone.Method cancelRowUpdates()cancelRowUpdates Methods cancelRowUpdates Synopsis: public void cancelRowUpdates() throws java.sql.SQLException; ExceptionsSQLExceptionif an error occurs.The cancelRowUpdates() method may be called after calling an updateXXX() method(s) and before calling updateRow() to rollback the updates made to a row. If no updates have been made or updateRow() has already been called, then this method has no effect. It notifies listeners that a row has changed, if it has effect.Method clearWarnings()clearWarnings Methods clearWarnings Synopsis: public void clearWarnings() throws java.sql.SQLException; ExceptionsSQLExceptionif a database-access error occurs.After this call getWarnings returns null until a new warning is reported for this ResultSet.Method close()close Methods close Synopsis: public void close() throws java.sql.SQLException; ExceptionsSQLExceptionif an error occurs.Releases the current contents of this rowset, discarding outstanding updates. The rowset contains no rows after the method release is called. This method sends a RowSetChangedEvent object to all registered listeners prior to returning.Method columnUpdated(int)columnUpdated Methods columnUpdated Synopsis: public boolean columnUpdated(int columnIndex) throws java.sql.SQLException; Parameters columnIndex - the first column is 1, the second is 2, ... return - true if the column has been updated ExceptionsSQLExceptionif a database-access error occursDetermine if the column from the current row has been updated.Method createCopy()createCopy Methods createCopy Synopsis: public RowSet createCopy() throws java.sql.SQLException; ExceptionsSQLExceptionif an error occurs.Creates a RowSet object that is a deep copy of this OPLCachedRowSet object's data. Updates made on a copy are not visible to the original rowset; a copy of a rowset is completely independent from the original. Making a copy saves the cost of creating an identical rowset from first principles, which can be quite expensive. For example, it doesn't do the query to a remote database server.Method createShared()createShared Methods createShared Synopsis: public RowSet createShared() throws java.sql.SQLException; ExceptionsSQLExceptionif an error occurs.Returns a new rowset object backed by the same data. Updates made by a shared duplicate are visible to the original rowset and other duplicates. A rowset and its duplicates form a set of cursors that iterate over a shared set of rows, providing different views of the underlying data. Duplicates also share property values. So, for example, if a rowset is read-only then all of its duplicates will be read-only.Method deleteRow()deleteRow Methods deleteRow Synopsis: public void deleteRow() throws java.sql.SQLException; ExceptionsSQLExceptionif a database-access error occurs, or if called when on the insert row.Delete the current row from this OPLCachedRowSet object and it notifies listeners that a row has changed. Cannot be called when the cursor is on the insert row. The method marks the current row as deleted, but it does not delete the row from the underlying data source. The method acceptChanges must be called to delete the row in the data source.Method execute()execute Methods execute Synopsis: public void execute() throws java.sql.SQLException; ExceptionsSQLExceptionif an error occurs.Populates this OPLCachedRowSet object with data. This form of the method uses the rowset's user, password, and url or data source name properties to create a database connection. If properties that are needed have not been set, this method will throw an exception. Another form of this method uses an existing JDBC Connection object instead of creating a new one; therefore, it ignores the properties used for establishing a new connection. The query specified by the command property is executed to create a ResultSet object from which to retrieve data. The current contents of the rowset are discarded, and the rowset's metadata is also (re)set. If there are outstanding updates, they are also ignored. The method execute closes any database connections that it creates.Method execute(Connection)execute Methods execute Synopsis: public void execute(java.sql.Connection _conn) throws java.sql.SQLException; Parameters _conn - a database connection ExceptionsSQLExceptionif an error occurs.Populates the rowset with data. The first form uses the properties: url/data source name, user, and password to create a database connection. If these properties haven't been set, an exception is thrown. The second form uses an existing JDBC connection object instead. The values of the url/data source name, user, and password properties are ignored when the second form is used. Execute() closes any database connections that it creates. The command specified by the command property is executed to retrieve the data. The current contents of the rowset are discarded and the rowset's metadata is also (re)set. If there are outstanding updates, they are also ignored.Method findColumn(String)findColumn Methods findColumn Synopsis: public int findColumn(java.lang.String columnName) throws java.sql.SQLException; Parameters columnName - the name of the column return - the column index ExceptionsSQLExceptionif a database-access error occurs.Map a Resultset column name to a ResultSet column index.Method first()first Methods first Synopsis: public boolean first() throws java.sql.SQLException; ExceptionsSQLExceptionif a database-access error occurs, or rowset type is TYPE_FORWARD_ONLY.Moves to the first row in the rowset. It notifies listeners that the cursor has moved.Method getArray(int)getArray Methods getArray Synopsis: public Array getArray(int colIndex) throws java.sql.SQLException; Parameters colIndex - the first column is 1, the second is 2, ... return - an object representing an SQL array Get an array column.Method getArray(String)getArray Methods getArray Synopsis: public Array getArray(java.lang.String colName) throws java.sql.SQLException; Parameters colName - the column name return - an object representing an SQL array Get an array column.Method getAsciiStream(int)getAsciiStream Methods getAsciiStream Synopsis: public InputStream getAsciiStream(int columnIndex) throws java.sql.SQLException; Parameters columnIndex - the first column is 1, the second is 2, ... return - a Java input stream that delivers the database column value as a stream of one byte ASCII characters. If the value is SQL NULL then the result is null. ExceptionsSQLExceptionif a database-access error occurs.A column value can be retrieved as a stream of ASCII characters and then read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a get method implicitly closes the stream. . Also, a stream may return 0 for available() whether there is data available or not.Method getAsciiStream(String)getAsciiStream Methods getAsciiStream Synopsis: public InputStream getAsciiStream(java.lang.String columnName) throws java.sql.SQLException; Parameters columnName - is the SQL name of the column return - a Java input stream that delivers the database column value as a stream of one byte ASCII characters.
