Class Overview

The standard implementation of the JoinRowSet interface providing an SQL JOIN between RowSet objects.

The implementation provides an ANSI-style JOIN providing an inner join between two tables. Any unmatched rows in either table of the join are discarded.

Typically, a JoinRowSet implementation is leveraged by RowSet instances that are in a disconnected environment and thus do not have the luxury of an open connection to the data source to establish logical relationships between themselves. In other words, it is largely CachedRowSet objects and implementations derived from the CachedRowSet interface that will use the JoinRowSetImpl implementation.

Public Constructors

public JoinRowSetImpl ()

Constructor for JoinRowSetImpl class. Configures various internal data structures to provide mechanisms required for JoinRowSet interface implementation.

Throws
SQLException if an error occurs in instantiating an instance of JoinRowSetImpl

Public Methods

public boolean absolute (int row)

Moves this JoinRowSetImpl 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 JoinRowSetImpl 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 JoinRowSetImpl 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().

Parameters
row a positive number to indicate the row, starting row numbering from the first row, which is 1; a negative number to indicate the row, starting row numbering from the last row, which is -1; must not be 0
Returns
  • true if the cursor is on the rowset; false otherwise
Throws
SQLException if the given cursor position is 0 or the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

SQLException if (1) this method is called when the cursor is on the insert row, before the first row, or after the last row or (2) this rowset is ResultSet.CONCUR_READ_ONLY

public void execute ()

Populates this JoinRowSetImpl 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.

Throws
SQLException if an error occurs or the necessary properties have not been set

public void execute (Connection conn)

Populates this JoinRowSetImpl object with data, using the given connection to produce the result set from which data will be read. A second form of this method, which takes no arguments, uses the values from this rowset's user, password, and either url or data source properties to create a new database connection. The form of execute that is given a connection ignores these properties.

Parameters
conn A standard JDBC Connection object with valid properties that the JoinRowSet implementation can pass to a synchronization provider to establish a connection to the datasource
Throws
SQLException if an invalid Connection is supplied or an error occurs in establishing the connection to the data soure

public InputStream getUnicodeStream (int columnIndex)

This method is deprecated.
No replacement.

A column value can be retrieved as a stream of Unicode 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 Unicode.

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.

Parameters
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 this rowset
Returns
  • a Java input stream that delivers the database column value as a stream of two byte Unicode characters. If the value is SQL NULL then the result is null.
Throws

public InputStream getUnicodeStream (String columnName)

This method is deprecated.
use the method getCharacterStream instead

Retrieves the value stored in the designated column of the current row as a java.io.InputStream object. A column value can be retrieved as a stream of Unicode 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 Unicode.

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 getXXX method implicitly closes the stream.

Parameters
columnName a String object giving the SQL name of a column in this JoinRowSetImpl object
Returns
  • a Java input stream that delivers the database column value as a stream of two-byte Unicode characters. If the value is SQL NULL, the result is null.
Throws
SQLException if the given column name does not match one of this rowset's column names or the cursor is not on one of this rowset's rows or its insert row

public SQLWarning getWarnings ()

The first warning reported by calls on this CachedRowSetImpl object is returned. Subsequent CachedRowSetImpl warnings will be chained to this SQLWarning.

The warning chain is automatically cleared each time a new row is read.

Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by statement methods (such as reading OUT parameters) will be chained on the Statement object.

Returns
  • the first SQLWarning or null

public String getWhereClause ()

Return a SQL-like description of the WHERE clause being used in a JoinRowSet object instance. An implementation can describe the WHERE clause of the SQL JOIN by supplying a SQL strings description of JOIN or provide a textual description to assist applications using a JoinRowSet.

Returns
  • whereClause a textual or SQL descripition of the logical WHERE cluase used in the JoinRowSet instance
Throws
SQLException if an error occurs in generating a representation of the WHERE clause.

public void insertRow ()

Inserts the contents of this JoinRowSetImpl object's insert row into this rowset immediately following the current row. If the current row is the position after the last row or before the first row, the new row will be inserted at the end of the rowset. This method also notifies listeners registered with this rowset that the row has changed.

The cursor must be on the insert row when this method is called.

Throws
SQLException if (1) the cursor is not on the insert row, (2) one or more of the non-nullable columns in the insert row has not been given a value, or (3) this rowset is ResultSet.CONCUR_READ_ONLY

public boolean isAfterLast ()

Indicates whether the cursor is after the last row in this JoinRowSetImpl object.

Returns
  • true if the cursor is after the last row; false otherwise or if the rowset contains no rows
Throws
SQLException if an error occurs

public boolean isBeforeFirst ()

Indicates whether the cursor is before the first row in this JoinRowSetImpl object.

Returns
  • true if the cursor is before the first row; false otherwise or if the rowset contains no rows
Throws
SQLException if an error occurs

public boolean isFirst ()

Indicates whether the cursor is on the first row in this JoinRowSetImpl object.

Returns
  • true if the cursor is on the first row; false otherwise or if the rowset contains no rows
Throws
SQLException if an error occurs

public boolean isLast ()

Indicates whether the cursor is on the last row in this JoinRowSetImpl object.

Note: Calling the method isLast may be expensive because the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in this rowset.

Returns
  • true if the cursor is on the last row; false otherwise or if this rowset contains no rows
Throws
SQLException if an error occurs

public boolean last ()

Moves this JoinRowSetImpl object's cursor to the last row and returns true if the operation was successful. This method also notifies registered listeners that the cursor has moved.

Returns
  • true if the cursor is on a valid row; false otherwise or if there are no rows in this JoinRowSetImpl object
Throws
SQLException if the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

public void moveToCurrentRow ()

Moves the cursor for this JoinRowSetImpl object to the current row. The current row is the row the cursor was on when the method moveToInsertRow was called.

Calling this method has no effect unless it is called while the cursor is on the insert row.

Throws
SQLException if an error occurs

public void moveToInsertRow ()

Moves the cursor for this JoinRowSetImpl 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. A getXXX method should be called on a column only after an updateXXX method has been called on that column; otherwise, the value returned is undetermined.

Throws
SQLException if this JoinRowSetImpl object is ResultSet.CONCUR_READ_ONLY

public boolean next ()

Moves the cursor down one row from its current position and returns true if the new cursor position is a valid row. The cursor for a new ResultSet object is initially positioned before the first row. The first call to the method next moves the cursor to the first row, making it the current row; the second call makes the second row the current row, and so on.

If an input stream from the previous row is open, it is implicitly closed. The ResultSet object's warning chain is cleared when a new row is read.

Returns
  • true if the new current row is valid; false if there are no more rows
Throws
SQLException if an error occurs or the cursor is not positioned in the rowset, before the first row, or after the last row

public boolean previous ()

Moves this JoinRowSetImpl 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 JoinRowSetImpl 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 JoinRowSetImpl 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);
         int age = crs.getInt(2);
         short ssn = crs.getShort(3);
         System.out.println(name + "   " + age + "   " + ssn);
     }
This method throws an SQLException if the cursor is not on a row in the rowset, before the first row, or after the last row.

Returns
  • true if the cursor is on a valid row; false if it is before the first row or after the last row
Throws
SQLException if the cursor is not on a valid position or the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

public void readXml (InputStream iStream)

Reads a stream based XML input to populate an WebRowSet

Parameters
iStream the java.io.InputStream from which this WebRowSet object will be populated
Throws
SQLException if a data source access occurs
IOException if a IO exception occurs

public void readXml (Reader reader)

Reads this JoinRowSet object in its XML format.

Parameters
reader the java.io.Reader stream from which this WebRowSet object will be populated
Throws
SQLException if a database access error occurs

public void refreshRow ()

Sets the current row with its original value and marks the row as not updated, thus undoing any changes made to the row since the last call to the methods updateRow or deleteRow. This method should be called only when the cursor is on a row in this rowset.

Throws
SQLException if the cursor is on the insert row, before the first row, or after the last row

public boolean relative (int rows)

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 JoinRowSetImpl 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 JoinRowSetImpl 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.

Parameters
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
Returns
  • true if the cursor is on a row in this JoinRowSetImpl object; false otherwise
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

public void removeRowSetListener (RowSetListener listener)

Removes the designated object from this JoinRowSet object's list of listeners. If the given argument is not a registered listener, this method does nothing. Note: if the RowSetListener object is null, this method silently discards the null value.

Parameters

Returns
  • true if (1)the current row is blank, indicating that the row has been deleted, and (2)deletions are detected; false otherwise
Throws
SQLException if the cursor is on a valid row in this rowset
See Also

public boolean rowInserted ()

Indicates whether the current row has been inserted. The value returned depends on whether or not the rowset can detect visible inserts.

Returns
  • true if a row has been inserted and inserts are detected; false otherwise
Throws
SQLException if the cursor is on the insert row or not not on a valid row
See Also

public boolean rowUpdated ()

Indicates whether the current row of this JoinRowSetImpl object has been updated. The value returned depends on whether this rowset can detect updates: false will always be returned if it does not detect updates.

Returns
  • true if the row has been visibly updated by the owner or another and updates are detected; false otherwise
Throws
SQLException if the cursor is on the insert row or not on a valid row
See Also

public void setJoinType (int type)

Sets the type of SQL JOIN that this JoinRowSet object will use. This method allows an application to adjust the type of JOIN imposed on tables contained within this JoinRowSet object and to do it on the fly. The last JOIN type set determines the type of JOIN to be performed.

public CachedRowSet toCachedRowSet ()

Creates a separate CachedRowSet object that contains the data in this JoinRowSet object.

If any updates or modifications have been applied to this JoinRowSet object, the CachedRowSet object returned by this method will not be able to persist the changes back to the originating rows and tables in the data source because the data may be from different tables. The CachedRowSet instance returned should not contain modification data, such as whether a row has been updated or what the original values are. Also, the CachedRowSet object should clear its properties pertaining to its originating SQL statement. An application should reset the SQL statement using the RowSet.setCommand method.

To persist changes back to the data source, the JoinRowSet object calls the method acceptChanges. Implementations can leverage the internal data and update tracking in their implementations to interact with the SyncProvider to persist any changes.
