Populates this CachedRowSetImpl object with data from the given ResultSet object. This method is an alternative to the method execute for filling the rowset with data. The method populate does not require that the properties needed by the method execute, such as the command property, be set. This is true because the method populate is given the ResultSet object from which to get data and thus does not need to use the properties required for setting up a connection and executing this CachedRowSetImpl object's command.

Propagates all row update, insert, and delete changes to the underlying data source backing this CachedRowSetImpl object. 

NoteIn the reference implementation an optimistic concurrency implementation is provided as a sample implementation of a the SyncProvider abstract class. 

This method fails if any of the updates cannot be propagated back
to the data source.  When it fails, the caller can assume that
none of the updates are reflected in the data source.
When an exception is thrown, the current row
is set to the first "updated" row that resulted in an exception
unless the row that caused the exception is a "deleted" row.
In that case, when deleted rows are not shown, which is usually true,
the current row is not affected.

 If no SyncProvider is configured, the reference implementation leverages the RIOptimisticProvider available which provides the default and reference synchronization capabilities for disconnected RowSets. 
Throws:
  • SQLException – if the cursor is on the insert row or the underlying
         reference synchronization provider fails to commit the updates
         to the datasource
  • SyncProviderException – if an internal error occurs within the SyncProvider instance during either during the process or at any time when the SyncProvider instance touches the data source.

Populates this CachedRowSetImpl 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.

Retrieves the name of the SQL cursor used by this CachedRowSetImpl object. 
In SQL, a result table is retrieved through a cursor that is named. The current row of a ResultSet can be updated or deleted using a positioned update/delete statement that references the cursor name. To ensure that the cursor has the proper isolation level to support an update operation, the cursor's SELECT statement should be of the form select for update. If the for update clause is omitted, positioned updates may fail. 
JDBC supports this SQL feature by providing the name of the SQL cursor used by a ResultSet object. The current row of a result set is also the current row of this SQL cursor. 
Note: If positioned updates are not supported, an SQLException is thrown. 
Throws:
Returns:the SQL cursor name for this CachedRowSetImpl object's cursor

Retrieves a ResultSetMetaData object instance that contains information about the CachedRowSet object. However, applications should cast the returned object to a RowSetMetaData interface implementation. In the reference implementation, this cast can be done on the RowSetMetaDataImpl class. 

For example:

RowSetMetaDataImpl metaData =
    (RowSetMetaDataImpl)crs.getMetaData();
// Set the number of columns in the RowSet object for
// which this RowSetMetaDataImpl object was created to the

Retrieves the value of the designated column in the current row of this CachedRowSetImpl object as an Object value. 
 The type of the Object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC 3.0 specification. 

This method may also be used to read datatabase-specific
abstract data types.

 This implementation of the method getObject extends its behavior so that it gets the attributes of an SQL structured type as an array of Object values. This method also custom maps SQL user-defined types to classes in the Java programming language. When the specified column contains a structured or distinct value, the behavior of this method is as if it were a call to the method getObject(columnIndex,
this.getStatement().getConnection().getTypeMap()). 
Params:
  • columnIndex – the first column is 1, the second is 2, and so on; must be 1 or larger and equal to or less than the number of columns in the rowset
Throws:

Moves this CachedRowSetImpl object's cursor to the row number specified. 
If the number is positive, the cursor moves to an absolute row with respect to the beginning of the rowset. The first row is row 1, the second is row 2, and so on. For example, the following command, in which crs is a CachedRowSetImpl object, moves the cursor to the fourth row, starting from the beginning of the rowset. 

   crs.absolute(4);



 If the number is negative, the cursor moves to an absolute row position with respect to the end of the rowset. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) moves it on the next-to-last row, and so on. If the CachedRowSetImpl object crs has five rows, the following command moves the cursor to the fourth-to-last row, which in the case of a rowset with five rows, is also the second row, counting from the beginning. 

   crs.absolute(-4);


If the number specified is larger than the number of rows, the cursor
will move to the position after the last row. If the number specified
would move the cursor one or more rows before the first row, the cursor
moves to the position before the first row.

 Note: Calling absolute(1) is the same as calling the method first(). Calling absolute(-1) is the same as calling last(). 
Params:

Moves the cursor the specified number of rows from the current
position, with a positive number moving it forward and a
negative number moving it backward.

 If the number is positive, the cursor moves the specified number of rows toward the end of the rowset, starting at the current row. For example, the following command, in which crs is a CachedRowSetImpl object with 100 rows, moves the cursor forward four rows from the current row. If the current row is 50, the cursor would move to row 54. 

   crs.relative(4);



 If the number is negative, the cursor moves back toward the beginning the specified number of rows, starting at the current row. For example, calling the method absolute(-1) positions the cursor on the last row, absolute(-2) moves it on the next-to-last row, and so on. If the CachedRowSetImpl object crs has five rows, the following command moves the cursor to the fourth-to-last row, which in the case of a rowset with five rows, is also the second row from the beginning. 

   crs.absolute(-4);

 If the number specified is larger than the number of rows, the cursor will move to the position after the last row. If the number specified would move the cursor one or more rows before the first row, the cursor moves to the position before the first row. In both cases, this method throws an SQLException. 
 Note: Calling absolute(1) is the same as calling the method first(). Calling absolute(-1) is the same as calling last(). Calling relative(0) is valid, but it does not change the cursor position. 
Params:
  • rows – an int indicating the number of rows to move the cursor, starting at the current row; a positive number moves the cursor forward; a negative number moves the cursor backward; must not move the cursor past the valid rows
Throws:
  • SQLException – if there are no rows in this rowset, the cursor is positioned either before the first row or after the last row, or the rowset is type ResultSet.TYPE_FORWARD_ONLY

Moves this CachedRowSetImpl object's cursor to the previous row and returns true if the cursor is on a valid row or false if it is not. This method also notifies all listeners registered with this CachedRowSetImpl object that its cursor has moved. 
 Note: calling the method previous() is not the same as calling the method relative(-1). This is true because it is possible to call previous() from the insert row, from after the last row, or from the current row, whereas relative may only be called from the current row. 
 The method previous may used in a while loop to iterate through a rowset starting after the last row and moving toward the beginning. The loop ends when previous returns false, meaning that there are no more rows. For example, the following code fragment retrieves all the data in the CachedRowSetImpl object crs, which has three columns. Note that the cursor must initially be positioned after the last row so that the first call to the method previous places the cursor on the last line. 

    crs.afterLast();
    while (previous()) {
        String name = crs.getString(1);

Moves the cursor for this CachedRowSetImpl object to the insert row. The current row in the rowset is remembered while the cursor is on the insert row. 
 The insert row is a special row associated with an updatable rowset. It is essentially a buffer where a new row may be constructed by calling the appropriate updateXXX methods to assign a value to each column in the row. A complete row must be constructed; that is, every column that is not nullable must be assigned a value. In order for the new row to become part of this rowset, the method insertRow must be called before the cursor is moved back to the rowset. 
 Only certain methods may be invoked while the cursor is on the insert row; many methods throw an exception if they are called while the cursor is there. In addition to the updateXXX and insertRow methods, only the getXXX methods may be called when the cursor is on the insert row.

     * After populating this rowset with data, the method

Updates the designated column with a character stream value, which will
have the specified number of bytes. The driver does the necessary conversion
from Java character format to the national character set in the database.
It is intended for use when updating NCHAR, NVARCHAR and LONGNVARCHAR columns.
The updater methods are used to update column values in the current row or
the insert row. The updater methods do not update the underlying database;
instead the updateRow or insertRow methods are called to update the database.

Params:
  • columnIndex – - the first column is 1, the second is 2, ...
  • x – - the new column value
  • length – - the length of the stream
Throws:
Since:1.6
